Biology Extinction Question?

Question

Put citations in your discussion for each question

Research the causes of extinction today. Are all, or most, of the causes the result of human intervention?

Answer 1

Do your own homework, write your own papers, cite your own sources.

Answer 2

Research is more than just asking for other folks to tell you the answers - it's actively looking for answers yourself. This can be tough when you're just starting out, so you might want to start by doing a search on 'extinction', and then start seeing what you can find out about organisms that have become extinct over the past century or so. Maybe compare what's known or conjectured about the causes of modern extinctions to past extinctions, like the extinctions in the Triassic (when dinosaurs appeared and took over many of the land niches), at the end of the Cretaceous (when lots and lots of organisms went belly-up), and during the Pleistocene (when most of the really large mammals, especially in North America, vanished). You might look up Labrador Duck, Great Auk and Carolina Parakeet for some interesting insights, as well as doing a search on 'flightless endemic species'. The library might help, but there aren't too many books that discuss extinction as more than a passing note. Good luck!

Answer 3

One can argue the fact that because we are losing species at the same rate today as occurred during the Cretaceous–Tertiary extinction event which saw the loss of all the major dinosaur groups that man has a big hand in it..

I guess when you have 6 plus billion of any species it's going to have an effect... If one bear poops in the woods ..no big deal but when you got 6 billion bears pooping ..you got a problem ;-) and that IS effecting ever other critter on this planet...

Some can survive and unfortunately some can't handle the can that occurs in the environment as a result of human pressure.
RESEARCH it yourself...you might actually learn something ;-)
