The global climate continues to warm and extreme weather increases. Which animals are better able to withstand the effects of climate change?
Global climate warming has been happening, and extreme weather has also increased, and the lives of small animals will also be affected. Scientists have studied some mammals living on land and found that llamas and African elephants have relatively strong cold resistance, and they are not easily harmed by extreme climate. These two animals have relatively long lifespans, few offspring, and strong individual survivability. And some small mammals with many offspring, such as mice, are easily harmed by the weather. As the weather changes, small animals may also experience some different changes due to the regional climate. For example, individual life spans may become longer, but offspring may decrease.
People can take off their clothes when the weather is hot, and when it is cold, they can hide in the underwear in the house and face the brazier or stove to keep warm. Therefore, compared with animals, humans are also more resistant to extreme weather. Adults must rely on tools. If they lose their tools, there is no way for people to survive. Under the same conditions, it is definitely easier for animals to survive in this kind of weather, because they rely on their own bodies to resist various weather effects.
Through the above research, we can see that the survival ability of large animals is still better than that of small animals, and their lifespans are also longer. For example, elephants can live a long time, but mice cannot. However, elephants have relatively few offspring, and it takes a lot of effort to give birth to a baby elephant. Therefore, different animals will undergo different changes in response to extreme weather, which is also a result of natural selection. In order to cope with natural conditions such as drought, large animals will invest more energy in their offspring, hoping that their offspring will live longer. This way each generation will be better than the last, and the genes of the large animals are preserved.
The earth is constantly changing, and human research has not stopped.
