How can humans increase the rate of endangered of extinct species

a. reduce environmental impacts.

b. build and populate more zoos.

c. pass more laws about land use.

d. introduce new predators to an environment.

I would think A. Reduce Environmental Impacts.

If you build and populate more zoos, some of the endangered species might not be able to survive in captivity

If you introduce new predators they are going to kill all the endangered species and if you pass new laws about land use some people may kill the species

It's D. If you introduce new predators to an environment you will reduce a species population, and introducing a new predator can be done if humans release a predator that isn't usually in that environment. Plus, I took the test. :-)

probably not if net force is zero

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.
