There are four ways that people threaten other species. 1) Human Activity is when human’s destruction of a natural habitat such as forest leads to the decline of several species. 2) Invasive species is where people introduced species into other communities where they were not accustomed to the environment. Also, the new invasive species have no knowledge about the surroundings and the new habitat (Withgott, & Laposata, 2012).

Humans are large contributors to the decline of biodiversity. Two individuals interact between
