What are the reasons for the decline in polar bear breeding populations and the brink of extinction?

Polar bear. As the name suggests, it is a species of bear that lives in the Arctic.

Animals, they are the largest land carnivores in the world.

Their fur is white and flawless, hence the white bears.

Ice bears and other aliases. Polar bears have small heads and small ears, and they are very round, which makes them look very cute, but they eat seals and are particularly domineering in the Arctic, so it can be said that they are the overlords of the Arctic. They are very clever when hunting, they will first find out where the seals' breathing holes are, and then wait for the opportunity to move, once the seals show their heads, polar bears will immediately grab the seals and use their sharp claws to drag the seals out of the breathing holes.

If a seal happens to be encountered by a polar bear while on shore, the polar bear will hide out of sight of the seal, and then get close enough to catch the seal.

At present, the number of polar bears is slowly decreasing and even extinct, what is the reason? The first is because of the climate. Now the temperature of the world is rising, the living environment of polar bears is also being damaged, the ice floe in the Arctic is slowly melting due to the increase in climate, polar bears have nowhere to go, the range of activity is very small, slowly many polar bears are dying, and may face the danger of extinction in the future, especially in need of human protection.

The second is because of environmental damage. Polar bears rely on the hunt of seals, especially crested seals and saddle seals.

Seals like that, and walruses in addition to that.

Fish, seabirds, and other animals sometimes hunt and even eat carrion, making them veritable carnivores. If the habitat is destroyed or the hunting environment is changed, and there is less to hunt, then the survival of polar bears is greatly threatened, and extinction is not far away.

The third is because of human hunting. It is not the first time that humans have harmed animals for profit, and the endangerment of polar bears has a lot to do with humans, polar bears are scattered, and some polar bears may be trapped in large fishing nets and lose their lives. Polar bears may kill their companions if they lose the animals they hunt.

The main reason is the rise in global temperatures, which has led to the melting of glaciers, which has reduced the habitat and range of polar bears, which in turn has led to a decrease in the breeding rat food for polar bears.

In recent years, as the global temperature has warmed, the glaciers in the polar regions have gradually dissolved, and polar bears rely on glaciers for predation, which makes their predatory space smaller and more difficult, resulting in many polar bears starving to death because they can't catch food.

As the global climate warms and many icebergs melt, polar bears have no place to stay, and the number of breeders will naturally decrease.

Personally, I feel that because of global warming, glaciers are melting, so that polar bears have fewer places to live, and their predation conditions are reduced, and most of them are starving to death, so their reproductive ability is also reduced.

Global warming, a large number of glaciers melted, resulting in a very big change in the environment in which they live, a large number of human hunting, resulting in a sharp decline in the population.

The main reason is that global warming and melting glaciers have led to less and less living space and food for polar bears.

Because of food and habitat problems, they thought that global warming and glaciers melted, causing them to lose their homes and find no food.

After 80 years, the polar bear may never be seen again, and if it does happen, it will undoubtedly be a heart-wrenching event. So, what are the causes of polar bears' extinction? First, global warming; second, there are people who engage in illegal hunting; Thirdly, there is a problematic obstacle to their reproduction.

1. Global warming and rising temperatures

According to the relevant data report, as the global temperature is getting higher and higher, even exceeding people's expectations, the ice and snow in the Arctic are melting faster and faster, and the polar bears have suffered damage to their former homes. At the same time, the variety of foods that they usually eat is becoming less and less, and even worse, there have been news that polar bears have no way to eat and have to go into villages to forage for food. Therefore, as this series of circumstances changes, the survival of polar bears is under major threat, and it is possible that they will become extinct in the next few decades.

2. Illegal hunting, polar bears are becoming less and less

Although China has introduced a series of relevant policies for the protection of animals, and even severely punished those who break the law, there are still illegal elements behind it, in order to obtain some benefits from it, secretly hunting polar bears, using them for illegal trading, and even selling them to people in other countries. As a result, polar bears have also begun to gradually decrease because of their greed.

Third, there is a problem with reproduction

As the global temperature begins to rise, the Arctic ice floes will begin to melt, and polar bears used to rely on ice floes to freeze their food, so that they can get less food, their bodies will begin to change, and many will become malnourished, resulting in a decline in reproductive ability, and the number of polar bears will become smaller and smaller.

At present, the normal survival of polar bears is in a relatively critical state, since the past cannot be reversed, but I hope that everyone from now on, can use their own actions to reduce some of the damage to their homes: do not litter, implement garbage classification, love the environment, low-carbon travel.

1 They spend most of their time in a "stationary" state, sleeping and resting can better save physical energy, and a small part of the time is spent walking on land to find food, but polar bears often snatch food among themselves.

2 Polar bears rely on glaciers for predation, and in recent years, the global temperature has risen, resulting in the continuous dissolution of glaciers in the Arctic, making their living space smaller and smaller, and the difficulty of predation has increased, and many polar bears have starved to death because they could not catch prey.

3 Although the influence of climate is the main reason for the decline of their numbers, human environmental pollution, poaching also accounts for a large part, although the impact of one or two degrees of temperature reduction is not very great for humans, but for other animals it is indeed fatal, and the maintenance of the food chain requires many influences.

Because of the temperature, lack of water, lack of food, the environment has been damaged, and polar bears are not suitable for the season.

Global temperature warming, polar bears living in a gradually harsh environment, ice and snow melting, the temperature is gradually rising, by the serious hunting by humans, affected by these comprehensive factors, polar bears may become extinct in 80 years, so in this case, we must protect accordingly.

To avoid polar bears.

To be extinct, we should first focus on protecting the food of polar bears. Because only having enough food will not affect the survival of polar bears. In addition, it is necessary to control the temperature of the environment, polar bears are only suitable for this cold environment, if the temperature is relatively high, this may naturally affect the living environment.

The last point is the need to strengthen the breeding of polar bears, which is the key of the key.

1. Protect the food of polar bears.

Not long ago, a team of researchers spotted an extremely hungry polar bear gnawing on a dolphin.

And the dolphins that are leftover from the food are also stored directly, which is indeed a phenomenon that makes people feel unbelievable. Scientists have so far not seen polar bears eat dolphins, as most polar bears only eat seals. Storing food in snow and ice is also a very strange phenomenon, but it also makes everyone understand that if you can store all your food in ice, you can effectively ensure the food of polar bears.

2. Pay attention to temperature control.

Arctic. It will also usher in a high temperature of 38 degrees, which is relatively rare so far. This high temperature can also cause significant glacier melting in the Arctic, and the rate of melting is very fast.

With the gradual warming of the climate, this will naturally lead to the homelessness of polar bears, and the baby polar bears born have no place to rest, and a large number of deaths will occur. If some scientific means are used to effectively control the temperature of the environment, this will naturally be able to effectively avoid more hidden dangers.

3. Strengthen the breeding of polar bears.

The lifespan of polar bears is actually not very long, and the general lifespan is basically about 25 to 30 years, and individual polar bears may not even have this time stage. Moreover, most polar bears will be alone, and will not usually come into contact with other polar bears, and will only choose to contact with other partners when they enter the breeding season. In order to effectively avoid the extinction of polar bears, the first thing that should be chosen is to strengthen the breeding of polar bears, which is the key.

Slow down greenhouse gas emissions, care for the environment, don't litter, low-carbon lyricism, remove marine litter, reduce carbon dioxide emissions, and avoid glacier melting.

First of all, don't maliciously hunt polar bears. And to protect our environment so that the air doesn't warm and polar bears don't have a place to live.

You can let them have more children, don't bother, don't let them live in pollution.

Polar bears live on Arctic glaciers, because of global warming in recent years, the glaciers are slowly melting, so polar bears have no place to live, and often cannot prey on fish, so they are endangered. If we want to protect it, we need to keep the glaciers there.

The main thing is to reduce the emission of carbon dioxide, which is one of the greenhouse gases, and it is the most important gas。But how can we reduce CO2 emissions? Quite simply, because of the rise in living standards now, many people buy cars to get around, but did you know that there are a lot of greenhouse gases emitted by cars, so if it is not very necessary, we can choose public transportation.

Like the bus, although it can be a bit crowdedBut everyone takes a little less in a private carChina's billion-dollar population will emit much less carbon dioxide, which is of great significance for protecting the environment and slowing down global warming.

And we need to reduce the commercial felling of treesTrees absorb a lot of carbon dioxide every year to produce oxygen for us humans to survive, so we need to cut down trees protectively.

Trees play an important role in regulating the climateIn hot weather, trees can absorb heat, unlike land, which allows direct reflection of radiation, making local weather hotter.

At the same time, we do not litter, and we do garbage sorting at will。We can learn some knowledge about garbage sorting, just like the dry garbage sorting on the TV show before, which is very meaningful, unlike those meaningless entertainment. Especially in coastal areas, residents should pay more attention to this garbage, and do not let it flow into the ocean and destroy the marine ecology, so that polar bears can have food to satisfy their hunger.

We need to pay attention to saving paper and electricity, which are obtained from the consumption of the earth's resources。When we run out of resources, we can only plunder the resources of other creatures. As a result, many creatures are on the verge of extinction, not only the polar bear, he is just one of them, but many cute creatures are about to leave us.

The main reason for the extinction of polar bears is because of global warming, so reducing carbon emissions and keeping the earth's temperature stable is the root cause, so that polar bears can be truly protected.

We should dedicate some resources to building an artificial ecosystem for these polar bears, so that they can be better protected for a longer period of time.

Climate change in recent years has had a huge impact on polar bears and other species, and everyone should be low-carbon and strengthen the improvement of environmental pollution.

The main causes of polar bear mortality are melting glaciers, reduced food and poacher killing. We can start by protecting the environment, green and low-carbon, saving resources, and establishing relevant protection organizations, publicity and education.

We strive to protect the environment and prevent the atmosphere from warming. It's not our business alone. It is a contribution that the whole society, the whole country and even the whole world should make.

Polar bears are pitiful
