Please help me understand at least two ways the use of bioremediation can benefit society and two ways that it could be harmful.
Let's start by defining bioremediation: Bioremediation is any process which uses organisms (typically microorganisms, fungus, plants, or algae) or some component from the organism (i.e. enzymes) to return an environment to its natural state. Below I've listed just a few benefits and harms of bioremediation, along with some examples to get you thinking about further pluses and minuses of this technique.
How is bioremediation beneficial?
Bioremediation removes contaminants from an environment. The contamination was likely deleterious to the ecosystem and to public health, so by removing the contaminates, bioremediation can improved 1) public health, and 2) an ecosystem, including the ecosystem resources human society depends on (for example, clean water or ...
In this solution I define bioremediation and then speak to the benefits of using the method and the potential harms. I cite specific hypothetical examples.
