why might it be beneficial to regulate what species of plats and animals people are allowed to own in particular environments
Neko [114]
Hi there!

Regulating species and plants in a certain area is beneficial for a lot of reasons. Below I'll list one of the most important reasons for regulating.

- Invasive species. As a direct result of the danger invasive species pose, regulating animals and plants in an area can help reduce the risk of a non-native species wrecking havoc on the environment. In the past and as of today many pet owners buy plants and animals from across the globe. Once they get too big some release them into the environment without any regards for the potential disaster it could bring. An example of this would be the Burmese Python which completely upset the ecosystem of souther Florida once let loose.
