Why is preventing pollution at its source the first strategy in minimizing environmental risk?
a.

it is easier and more effective to prevent pollution than to clean up and dispose of waste.
b.

remediation of contamination is easier than pollution prevention.
c.

habitat restoration cannot be undertaken with modern technologies.
d.

safe waste disposal is the easiest was to minimize environmental risk.

The correct answer for this question is a) It is easier and more effective to prevent pollution than to clean up and dispose of waste.

Yes, it is more effective way to control environmental risk by preventing pollution at its source. First it help us to control the flow of toxicity through water and air. It is often more difficult and expensive to control pollution after it has been released into the environment so it will also help us to cut the cost of treatment of pollutants

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
