Some animals have adapted their bodies to live more successfully in their habitats. Like polar bears have a thicker layer of fat to survive the extreme winters. But due to human activities like deforestation, chemical production, etc. many animals are not only facing habitat loss but also are unable to survive the changes that are taking in their natural habitat. Like for eg., the increasing temperature in the polar regions due to global warming has caused a lot of inconvenience for the polar bears. Human beings should stop this destruction before it's too late and there is no other way to protect these organisms.
