Explain the term over exploitation in relation to commercial fisheries management.

-Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Overfishing and overhunting are both types of overexploitation.

-We have big boats, fancy GPS systems, and mechanized fishing lines, which causes more over exploitation

Overexploitation is a problem that threatens the oceans and marine species.

Overexploitation in fishing is related to the fact that so many examples of a marine species are captured that repopulation is impossible. This situation occurs due to the increase of the population in the countries. This is why large boats are now used for fishing and very aggressive techniques with all species, especially large carnivorous fish craving for their meat, but whose disappearance brings great imbalances.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

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."
