The document discusses how nature exists in a delicate balance, with many species relying on each other and the environment for survival. Climate change is disrupting this balance by reducing habitats and food sources. As ice caps melt and CO2 levels rise, polar bears, whales, and other Arctic animals are seeing their populations decline due to a lack of food and suitable living conditions. To maintain a healthy ecosystem, efforts must be taken to preserve the natural world and reduce human-caused damage to the environment.
