The correct answer is (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;
The role of environmental scientists is to monitor the effect of pollution on environment. The environmental scientists determine the effect of pollution on the plants and animals. If the environmental scientist will not be there then, there would be no one who can tell that there is an increase in the air, land and water pollution. There would be no one who can tell us the proper ways to dispose waste, and there will be many more similar problems related to the environment.
