The world of wildlife includes a huge number of species that live in various ecosystems on our planet, ranging from tropical forests and savannahs to polar ice and deep oceans. These animals play an important role in the ecosystems in which they live. They are involved in nutrition cycles, seed dispersal, plant pollination, and influence other aspects of the environment. Some of these animals are key species whose absence can significantly affect the ecosystem.

However, in present, many species of wild animals are threatened with extinction due to various factors, including the loss of their natural habitat, climate change, illegal wildlife trade, environmental pollution and other human activities. Therefore, it is very important to conserve and protect these animals and their habitats in order to maintain biodiversity and balance in ecosystems.
