To celebrate the international polar bear day we have made a list with fun facts that we collected over at our friends the Polar Bears International.
Check them out and make sure to do one small thing for the bears every day, whether it be taking a walk instead of using the car. Or if you want to push it even further you can go ahead and jump ship on fossil fuel altogether and get yourself an electric vehicle instead. Use the bus or just skip running to the store for that bag of chips that you know isn’t good for you either way. Small things matter when done by many!
When is the International Polar Bears Day
The internation polar bears day is at the 27th of February. #NationalPolarBearDay
Fun facts to celebrate the polar bears day
Polar bears are considered marine mammals just like whales, dolphins and seals. The fact is actually hidden in the bear’s Latin name, Ursus Maritimus, which means sea bear.
They are not really white. Their hair is pigment-free and transparent. It is also hollow which makes bright light and the snow around them reflect in their fur making it look white. If you see a polar bear straight after the molting period around spring/early summer they will look the whitest. Before the molting period begins they might look very yellow due to the oil that builds up in the fur due to their favorite snack, seals.
Polar bears hate getting dirty. In fact, they take snow-baths to get clean, which means they roll around in the snow after having a snack or getting dirty for any other reason. Dirty fur is a poor insulator and having proper insulation is important when you live in extreme colds.
Polar bears kiss to ask if the other might want to share a snack. Or they at least touch noses. The guesting bear will first walk around the bear until they feel comfortable enough to go ahead and ask for a share.
Polar bears don’t have territories, they have home ranges. This is due to the fact that their home area may change at any time due to the ice freezing up or melting. Some polar bears have been reported to wander places the size of Texas.
As marine mammals, they spend most of their time in Arctic. In cold weather, Polar Bears move to ice sea for hunting seals. Polar bears have thick fur as compared to other bears.
Different behavior, different times
Seasonal ice – Seals are available on ice seas, but there are areas where the seasonal ice sea is available. Polar bears wait for the winter season in such zones for hunting their food. It is not easy for them to live in such areas including Davis Strait, Baffin Bay, Western Hudson Bay, Foxe Basin, and Southern Hudson Bay.
Polar Basin Divergent Ice – As in such ice seas, in summer season ice melts. The polar bears travel a long distance in search of remaining ice packs or fast until the winter arrives. Polar bears are at high risk in these areas Chukchi Sea, Kara Sea, Barents Sea, Southern Beaufort Sea and the Laptev Sea.
Polar Basin Convergent Ice – Polar bears find more chances to hunt seals in such areas including Northern Beaufort Sea, Queen Elizabeth Islands, and Eastern Greenland. Polar bears do not need to travel much or fast, but scientists believe that after 75 years, ice will start melting in such areas.
Archipelago Ice – In regions like Gulf of Boothia, Lancaster Sound, Kane Basin, M’Clintock Channel, Viscount Melville Sound and Norwegian Bay, ice packs stay the whole year. Polar bears get more hunting grounds here.
Polar bears use body language, sounds and even smells for communicating with one another. Some of the typical responses of polar bears are,
When polar bears want to play, they head waging with one another from side to side.
When bears ask about something to another polar bear like for food, they slightly touch the nose of that bear with their nose.
Polar bears make a chuffing sound when they are feeling stressed.
Polar bear makes low growl for scolding her cubs.
Polar bears show his aggression by making the hissing sound.
During attack mode, polar bears’ head is down with ears that are laid back and a forward charging.
They growl deeply when communicating about the danger.
As a promoter for the arctic animals, polar bears first and foremost, we are always happy to hear about new climate-friendly transportation vehicles that emerge. Like the hoverboard for example. An electric transportation vehicle that has since it first got introduced spread like a wild-fire. Sadly, things ended pretty bad for some of those who jumped the gun on this new trend straight away.
We’ve taken a look at the effect these products may have on our planet and arctic wildlife.
What are the effects on our climate for using electric transportation
Perhaps you’ve read earlier in one of our articles about the small things and lifestyle changes you can do in order to lower your carbon footprint. If enough of us took the time to do at least one thing on our list the combined effect of everyone doing one small change to their lives would be huge. Not only for you but also for those with whom we share this planet, the animals.
The United States has done a great job cleaning up carbon dioxide outlets from power plants in order to generate natural and climate-friendly electricity. According to studies made, for the first time since 1979, cars, truck and airplanes emits more carbon dioxide than power plants do.
This is a huge step forward and a more than enough reason for us to start using different types of electric transportation.
We researched that even though there are different types of hoverboards with different battery sizes, the most standard one is 4400mAh. They are said to take you anywhere between 8-12 miles on a full charge which could easily translate into a store-run, going to school/work or the gym, there and back again.
A 4400mAh battery would consume ~125Wh of electricity in order to get from 0% to a 100% charge. At a cost of $0.14kWh it would cost no more than $0.14 x 0.125(kWh) = $0.0175.
For less than 10 cents per charge you can transport yourself + a backpack or 50lbs of groceries (depending on your weight) up to 8-12 miles. With the chart above in mind, we can draw to the conclusion that small electric vehicles like scooters, hoverboards or bikes used as substitutes for taking your car can have a very beneficial impact on today’s pollution of our planet.
Even though hoverboards target audience is kids, that could be you not having to take the car to pick them up or leave them at school. And considering these have the strongest batteries among the simple electric transportation vehicles, then using transportation for adults like scooters and bikes would end up consuming even less electricity. They often tend to go further on a full charge than hoverboards too. That due to the technology involved with balancing a humans total weight without making them fall off consumes more electricity.
For first-world countries across the world, using electronic vehicles can very much be a great but small investment for reducing the pollution of our planet. As long as there are things being done in order to ensure more natural and clean electricity. The impact will not only keep some of your hard-earned money in your pockets. It greatly affects the climate of our planet in a positive way.
Electric vs fueled transportation
Setting these two against each other to us feels meaningless, but we hope to be able to open your eyes to exactly what the differences between
With the above as an example. We estimate that a fully charged hoverboard can take you 10 miles (16 kilometers) and uses 0.125kWh of electricity per full charge.
We also estimate that a car uses about 1 liter of gas per 6 miles.
Hoverboard co2 outlet
Generating 1kWh with coal emits approximately 2 pounds of co2.
1kHw is equal to 80 miles of hoverboard-riding or 8 full charges.
A hoverboard passively emits 0.25 pounds of co2 per 10 miles or charge. (2 divided by 8 is equal to 0.25 pounds of co2 per charge.)
Car co2 outlet
Fuel used to take a car 10 miles (16 kilometers) are approximately 1.6 liters of gas.
1 liter of gas used by a car emits around 5.3 pounds of co2.
A car emits 8.48 pounds of co2 per 10 miles of driving. ( 5.3 times 1.6 equals 8.48 of co2 per 10 miles of usage.)
Next time you need to go somewhere close to home. If you have something that goes on batteries, plug it in and use that instead. Taking the car for shorter errands might even end up emitting more than the above-calculated co2 due to the fact that starting/stopping, traffic, and weather can have a negative effect on your car’s gas usage.
So for the love of all animals, our planet, and our kids. Seek to do the small things that add up to a huge difference.
Find all the information you need about baby polar bears
Polar bears are the unique symbol of the Arctic. As marine mammals, they spend most of their time in Arctic. In cold weather, Polar Bears move to ice sea for hunting seals. Many of the polar bear babies die during traveling from one place to another. They have thick fur as compared to other bears while the Cubs are with a thin layer of fur, that increases as they grow up.
As the changes in climate took place, global warming, it affected the entire population especially polar bear babies as they cannot travel long in search of food. It changed their life span and diet as well. It is believed that polar bears will disappear from planet Earth in 2100. They are sensitive to climate change. This issue must be taken seriously to stop their extinction.
Polar bear babies are mostly found on the top of ice packs. They can be found in areas including Russia, Canada, Norway, the United States of America(Alaska) and Greenland(Denmark).
The baby stays in the den after his birth. They spend most of their childhood in the den. Den provides them safety as they are young enough and cannot take care of themselves. Den keeps them warm. The dens are dug by their mothers.
A young polar bear travels up to 1000 kilometers for setting up its own home away from the mother once he becomes an adult.
The baby polar bear at early age nurture on their mother’s milk. The mother’s milk is nutritious, and Cubs grow rapidly in weight and size after taking it. Within few months, the baby is ready to eat solid foods like a seal. They take their mother feed for 13 to 19 weeks. The time is likely to increase with increasing number of siblings, insufficient food, and climate change.
For some time after birth polar bear babies are not able to find their prey and lactate on their mothers’ feed. Seals are the most favorite food as they grow up, rich on fat and proteins. The babies also eat walrus whale and beluga whale carcasses, vegetation (rarely) and various bird’s eggs. Polar bears and their babies migrate from one area to another for searching their prey and food.
Cubs at an early age are not able to hunt for themselves. The baby polar bears stay with their mothers. Their mothers teach them hunting and then they can hunt on their own. For almost two to three years’ polar bears eat the seals hunted by their mothers or mother’s milk. Polar bear cubs are prey for their mothers sometimes, as Cubs cannot hunt their food for 2-3 years.
The total estimate of the population of polar bears cubs is not available as it is not easy to keep track of how many of them stay alive. As due to climate changes, they have to travel from one distance to another in search of food. Therefore, many of them die during traveling while others are killed by predators. The reproduction process is slow that slows down the growth of population.
Birth of polar bears cubs
Polar bear’s life cycle changes from season to the season including mating, denning and birthing. As the reproductive cycle of the mother is about 2-3 years. The previous Cubs become strong and start living on their own before the newborn come.
As the spring season emerges and melting of ice starts, male polar bears look out for their mates. The initial mating takes place on ice sea.
During winter and fall, the female polar bear starts building a den. She will give birth to the cubs in the den. They make dens in areas filled with ice or near ice sea. They make a cave with an area in which she can turn around. She then waits inside the shelter for ice to cover its opening. During the six to eight months’ mother spends in the den, she does not eat anything.
During winter, between November to January, mother give birth to the 1 to 3 cubs. The newborns are covered with short fur and toothless and dependent on their mother.
Emerging from Den
During March or April, a polar bear comes out of the den as cubs are healthy enough until this time. From this period mother starts teaching her cubs about how they can survive in Arctic.
From two to three years, Cubs stay with their mother. Mother teaches them to swim, hunt, feed and most importantly survive. After three years, they leave their mothers and starts living on their own.
Polar bears are built for ice, and their body structure shows that.
Babies are born with thin hair that grows and increases with time. The fur of a polar bear cub need 4 to 8 weeks for growth, but some require up to 14 weeks for proper growth of their fur. After 14 weeks, they resemble their mothers.
Skin, Ears, & Tail
Cubs are covered with thick black skin, the thickness equal to 12.5 centimeters. The flabby skin and fur help them in staying warm. They have small ears and a short tail that conserves heat as much as possible for keeping them warm. Baby polar bears are toothless, cute little things.
Paws & Claws
They are born with small paws that lack nails or claws. Their paws help them to maintain balance while walking on the ice. The baby polar bears spend 8-14 weeks in the den and learn walking once they come out of the den. After 14 weeks, the claws of the Cubs start to grow so that he can learn and practice hunting. With the passage of time, his claws become strong and sharp.
Teaching baby polar bears
After emerging from the den, they stay with their mother. Their mother teaches them to walk, swim and hunt. Initially, mothers teach them to stalk the prey present on the surface of the land. Mother lower down their head and secretly follow the prey and grab it. The baby polar bears observe their mothers and learn hunting.
Polar Bears Extinction and Global Warming
Due to climate change, the overall population of polar bears got affected. The climate change is having adverse effects on the growth of baby polar bears. Global warming is creating huge risks for these small furry bears. As the amount of sea ice is disturbing. As global warming is making the ice melt quickly during summers, that force polar bears to travel miles away in search of prey. Many of the babies die during traveling while other become a prey of predators or male polar bears due to lack of food.
Measures to Control Polar Bear Extinction
It is ‘never too late to take action’ for saving baby polar bears and controlling global warming. These are some simple steps at an individual level which can save polar bears from extinction.
Vote such representatives for who plans to reduce the consumption of carbon in the society.
Spread awareness about how climate change can affect the overall environment.
Encourage community member to change their lifestyle.
Discuss facts related to global warming and its impacts on living beings.
Avoid vehicles that increase air pollution.
Increase use of fuel-efficient vehicles
Use efficient systems for insulation of the building.
Replace the light bulbs with the LED bulbs.
Utilize solar sources for generating power.
Do not waste water.
Use energy-efficient appliance and turn them off when not in use.
Increase consumption of whole foods.
Avoid purchase of such products that are formed as a result of deforestation.
Increase vegetables in your meals and decrease meat consumption.
Reduce your product consumption and recycle things.
These are small individual steps that can make a big difference in decreasing global warming. Don’t think that you cannot play your part or your actions will not affect the overall environment, as a single step can make a big difference. The government should also take measures for saving baby polar bears.
You made it all the way here to see me it must mean I managed to upset you! Did it need a fake to make you think about the problem? The extent at which the ice-caps are melting is unprecedented in the last 30 years.
And climate change could bring entire national economies to their knees, along with our daily lives! Even if we’re not skinning polar bears, we are already sacrificing their existence and our future! That is why it’s so important for all of us to act right now.
URSA is a leading manufacturer of thermal insulation materials that contribute to energy efficiency in buildings and by doing so reduce not only consumers’ energy bills but also CO2 emissions.
But there’s more.
To celebrate the re-opening of our Italian facilities, which were destroyed in 2012 during the earthquake we have launched the URSA Award dedicated to the best architectural projects offering maximum energy efficiency and lowest environmental impact regarding CO2 emissions, both essential features to deliver a sustainable building.
The URSA Award is our way of showing that using sustainable construction methods is the only way to reduce global warming.
But, there’s even more.
URSA is doing its part, let’s all do our bit make a donation now to our partner the Italian Climate Network, a non-profit association that works every day to combat global warming.
Your donation will be used to protect the environment and the future of our children!.
“Global warming causes the average temperatures in the world to increase.”
Around the North Pole, the cold season is becoming shorter, the sea ice melts earlier and the time during which polar bears can hunt for food diminishes every year.
This threat may seem remote, and difficult to explain to children growing up in more temperate regions of the world.
How can you make this situation more concrete and easier to understand? Here is what I propose.
If you do this project in the winter and it is cold enough where you live, fill a plastic tub or storage box with snow.
Pack the snow tightly. If it’s not cold enough outside, fill a plastic container with water and put it in the freezer until the water is frozen solid. Bring the frozen container into a warm room and put plastic polar bear figurines on the ice.
If you don’t have any polar bear figurines, you could make your own from play dough or paper.
Now, let the children observe what happens.
If you want to apply a more scientific method, start by asking the children to formulate hypotheses: “What do you think will happen?”, “How long is it going to take?”, etc.
Then, at regular intervals, let them observe what happens and let them measure the thickness of the ice.
Polar bears mainly feed on seals, which they hunt from the edge of sea ice.
With temperatures rising over the years, the ice floes shrink and the time during which polar bears can hunt for food diminishes as well.
As a result of these two effects, the survival of polar bears is threatened and in the long run, the species could disappear altogether.
This reality is represented in a very concrete(and simplified) way by the melting of the ice in the plastic container of our experiment.
Sometimes, dramatic images like this one are needed to inspire to action.
If you do this experiment, share the kid’s comments.
The polar bear is the world’s largest bear(along with the omnivorous Kodiak bear) with adult males weighing in at a whopping 770to 1,500 pounds. Polar bears are classified as marine mammals because they spend most of their lives on the sea ice of the Arctic Ocean. They have a thick layer of body fat and a water-repellant coat that insulates them from the cold air and water. Considered talented swimmers, they can sustain a pace of six miles per hour by paddling with their front paws and holding their hind legs flat like a rudder. Polar bears spend over 50 percent of their time hunting for food, but less than two percent of their hunts are successful. Their diet mainly consists of ringed and bearded seals because they need large amounts of fat to survive. Unlike grizzly bears, polar bears are not territorial. Although stereotyped as being aggressive, they are usually cautious confrontations and often choose to escape rather than fight. Polar bears are stealth hunters, and the victim is often unaware of the bear’s presence until the attack is underway.
However, due to the minuscule human population around the Arctic, such attacks are rare. Although polar bears live solitary lives, they have often been seen playing together for hours at a time and even sleeping in an embrace. Cubs are especially playful as well. Among young males, in particular, play-fighting may be a means of practicing for serious competition during mating seasons later in life. The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations currently in decline. Polar bears are forced to become long-distance swimmers to find food and places to sleep as Arctic ice continues to melt. New research published April 14 in the journal “Ecography” says that polar bears are swimming longer and longer distances as the ice they depend on for survival disappears.
One-hundred bears were tracked with GPS collars off the northern coasts of Alaska and Canada. In 2004, only 25 percent of these bears made swims of more than 31 miles, but in 2012, 69 percent of the bears were making these long journeys. In 2009, one female bear swam for nine days straight without stopping for food or rest. She traveled a total of 250 miles to reach a habitable ice slab.
Dr.Nicholas Pilford with the Institute for Conservation Research told NewsBeat Social his findings provide “another reminder of the rapid pace of environmental change in the arctic.
Maybe you’ve seen the image or read the tweet: “What doesn’t kill you makes you stronger. Except for bears, bears will kill you.”
Bears hold an important part of our imagination, especially on camping trips. It’s just turned autumn. Autumn is a beautiful time of year. Among the pleasantries of autumn are annual grade school class camping trips. I participated as a chaperoning parent in our children’s class camping trip – all memorable in one way or another – but one particularly memorable as to my choice of a campfire book.
My oldest son’s 4th-grade camping jamboree had all the makings of a great trip – great campground near a river, a Gold Rush town nearby, walks in the woods full of history and the warmth of a large campfire.
Everything was going great – an excellent hamburger dinner, Gold Rush style music, and camping under the stars – 0h – actually camping in a canvas tent. It was lights out. Everyone left to their respective tents. Fathers were in one group of tents with the boys, and mothers were in another group of tents with the girls.
My tent was well placed in the campground, and it was my job to oversee five boys. I’d planned well for the trip – warm clothes, hiking boots and a book that I knew the kids would love – Bear Attacks: Their Causes and Avoidance.
I knew that my storytelling aided by the book would add to the wonder of the wilderness. Once we were safe, all zipped up in our tents. I turned on my flashlight and asked the boys, not quite sleepy yet, if they would like for me to read them a story. The answer was a resounding yes; Oh, what dreams they must have enjoyed that night! Research shows that reading aloud enhances classroom instruction and improves academic achievement. I can’t say I was aware of that the investigation, but I figured that evoking the presence of bears on a campground full of fourth-graders was just what the doctor ordered.
Not long into a chapter of Bear Attacks, one of our young campers announced he wasn’t feeling too good and made a lightning-fast exit for his mother’s tent next door.
Momentarily pausing the story, I considered the possibility that the magic of reading aloud to children about killer bears might occasionally have a downside. No other parent chaperone, however, could bring the wonders of the wild to life quite as I could. The next morning I learned that Cory’s mother and some other chaperone mothers did not approve of my campground reading selection. Upon a two-or-three second reflection, I thought she made a fine point. For all remaining Fourth Grade Camping Trips, Bear Attacks stayed at home. Stalked by a Mountain Lion, I learned, proved much more kid-friendly.
I hope these give you some great ideas for your next camping trip.
North American Black Bears are omnivores, which means they eat a little bit of everything. The majority of their diet consists of grasses, fruits, and nuts, but they also get protein from insects, small mammals, and the carcasses of dead animals.
Even one taste of human food can cause a bear to change its behavior, and potentially become aggressive towards humans. Let’s take a look at the ways you can keep your food secure and bears safe at Lassen Volcanic National Park.
Camp sites in established campgrounds have food lockers. Put all of your food and scented items, like toiletries and bug repellent, in there when not in use. That way if a bear comes around, it won’t get a taste. Here at Lassen Volcanic, bears don’t associate vehicles with food, and we want to keep it that way.
So storing food and scented items in a hard-sided vehicle with the windows rolled up is appropriate. Make sure to keep ice chests and other food containers as hidden as possible. The trunk is a good place.
If you plan on heading into the backcountry for an overnight backpacking adventure in the wilderness, you must carry with you an approved bear-resistant food container, like a bear canister, to put all of your food and scented items in.
You can rent a bear canister from the Lassen Association at the Loomis Museum or the Kohm Yah-mah-nee Visitor Center Place the container on the ground at least 100 feet away from your tent.
If a bear does find it, it might bat it around, but it won’t get the smelly stuff inside.
And be sure not to leave your pack unattended at any time.
Do your part to keep Lassen’s bears safe, healthy, and wild, by properly storing your food and scented items when you come to enjoy your park.
The USGS conducts research on polar bears and has documented declines in their population. Survival rates and body size.
To better understand how sea ice decline in the Arctic affects polar bears, USGS scientists are using accelerometers to gather data about the energy needed for the bears to hunt for food.
The scientists use accelerometers to track the polar bear movements like a Wii-fit video game controller tracks yours.
Since the accelerometer data are cryptic, USGS scientists are using captive bears in zoos to understand what the data mean. Researchers did Geological Survey at the San Diego Zoo collecting accelerometer data from their adult female polar bear Tatiq.
And so the keepers here at the San Diego Zoo have been training Tatiq to wear a collar for the last four months and slowly getting her acclimated to the collar. And so now she’s able to wear the collar for about three hours a day without any issues. She’s totally comfortable wearing the collar and she doesn’t seem phased at all wearing it. And so researchers did videotaping her while she’s wearing this accelerometer collar to calibrate the accelerometer data.
Basically trying to understand what the accelerometer data looks like for different behaviors. So when Tatiq’s walking, what the accelerometer data looks like compared to when she’s swimming versus resting versus eating, with the intent of actually applying that information to accelerometer data we’recollecting from wild bears.
Researchers attached accelerometers to their GPS collars that they were deploying on wild polar bears in the Arctic. So this study should help them get a better understanding of how polar bears are responding to declines in sea ice and what the actual implications are for survival, body condition and then start to look at how future forecasts for declines might impact polar bears in the future.
