What could happen to the environment if there were no environmental scientists to monitor it? a. decline in air, land and water pollution; no one to ensure proper disposal of toxic wastes; decreased destruction of habitats; increase in species extinction; b. great increase in air, land and water pollution; no one to ensure proper disposal of toxic wastes; increased destruction of habitats; increase in species extinction; c. problems with enforcing the preservation of certain ecosystems and wildlife; great increase in air, land, and water pollution; decreased destruction of habitats; increase in species extinction d. increased destruction of habitats, decrease in species extinction; problems with enforcing the preservation of certain ecosystems and wildlife; prevent the depletion of earth's natural resources

b. great increase in air, land and water pollution; no one to ensure proper disposal of toxic wastes; increased destruction of habitats; increase in species extinction;

Explanation:

Environment scientists are the professionals who studies and survey about environment issues like pollution, species extinction or mass extinction and affect of natural calamity on the environment. They provide suitable solutions for these problems to the government and the local people. Hence, help in preserving the natural environment.

If there were no environment scientists to monitor the environment b. great increase in air, land and water pollution; no one to ensure proper disposal of toxic wastes; increased destruction of habitats; increase in species extinction; would occur.

This is because of the fact that there will be no awareness among the common people regarding the safety of the environment and no laws related to the environment protection will be implemented.
