Answer-Because when fossil fuels are burned,the fossil fuels are running out more and more and so sientists are trying to figure out a way for fossil fuels to become more of a renewable resources then a nonrenewable resource so that we have more of a likely cause that we will have a future use of all the fossil fuel that are about to run out just like an extinct species.

The right answer is A.
Insecticides are active substances or phytosanitary preparations with the property of killing insects, their larvae and / or their eggs. They are part of the family of pesticides, themselves included in the family of biocides, both of which are regulated in Europe by specific directives.
Some pestiids such as organoclorides are broad-spectrum, ie they act on several insects at the same time (whether they are good or bad).
