Which is a sustainable practice? why are invasive species dangerous to the environment?

For the first question, choose the option in which the practice would help in the preservation of nature, for example, by reducing pollution and waste, as well as protecting areas of wildlife from getting eradicated. For example, recycling would be a sustainable practice, in which you reuse hard-to-dispose man-made-materials.

For the second question, invasive species are dangerous to an environment, for they destroy the fragile original ecosystem. They generally would destroy one or more levels of the ecosystem, resulting in a total-reduction of the populations in each language, or else an imploding boom of a certain population that would soon strangle itself out from lack of resources.
