Many animals around the world are facing the risk of extinction in the wild, and this is happening for several reasons. One major cause is habitat destruction due to human activities such as deforestation, urbanization, and agriculture. As forests and other natural environments are cleared to make way for farms, cities, or industries, animals lose their homes and sources of food, leading to population declines. Additionally, climate change is altering ecosystems, making it difficult for some species to survive. For example, polar bears are struggling as ice caps melt, and many species are affected by rising temperatures and changes in weather patterns.
