What can be done to increase biodiversity in areas where it has been decreased?

Explanation:

Native plants are well adapted to local conditions and provide a low maintenance, drought resistant garden and can prevent local flooding. Attract “good” insects by planting pollen and nectar plants. Maintain wetlands by conserving water and reducing irrigation. Avoid draining water bodies on your property.

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

the answer is: metamorphic rocks often show the presence of fossils, also a
