Animals are one of the basic groups of life on Earth. They share a set of fundamental characteristics--they move, they feed on other organisms, they're multicellular and they reproduce sexually. They belong to the Kingdom Animalia, a group also known as the Metazoa, and, include organisms such as amphibians, birds and fish. The group also includes invertebrates and mammals as well as and reptiles. Wildlife is a term that traditionally refers to non-domesticated vertebrates, but has come into more general usage to refer to all wild plants, animals and other organisms. Domesticating wild species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts or forests, plains and other areas including the most developed urban sites, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around the world is impacted by human activities.
