Polar bear behavior

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.

Behavior

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.

Baby polar bears behave differently from when they are fully grown-up adults. When they are older they tend to travel more and disengages from their mothers.

Electric transportation, good or bad for the environment?

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.

Conclusion

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.)

Conclusion

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.

Baby Polar bear cubs fact and what you can do to save them

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.

Habitat

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.

Diet

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.

Hunting

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.

Population

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.

  • Mating

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.

  • Denning

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.

  • Birth

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.

  • Growing up

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.

  • Characteristics

Polar bears are built for ice, and their body structure shows that.

  • Fur

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.

  1. Vote such representatives for who plans to reduce the consumption of carbon in the society.
  2. Spread awareness about how climate change can affect the overall environment.
  3. Encourage community member to change their lifestyle.
  4. Discuss facts related to global warming and its impacts on living beings.
  5. Avoid vehicles that increase air pollution.
  6. Increase use of fuel-efficient vehicles
  7. Use efficient systems for insulation of the building.
  8. Replace the light bulbs with the LED bulbs.
  9. Utilize solar sources for generating power.
  10. Do not waste water.
  11. Use energy-efficient appliance and turn them off when not in use.
  12. Increase consumption of whole foods.
  13. Avoid purchase of such products that are formed as a result of deforestation.
  14. Increase vegetables in your meals and decrease meat consumption.
  15. 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.
