Trapping has severely reduced the population of rabbits in an ecosystem, as shown in the bar graph below. What is the most likely effect this will have on other organisms? A bar graph shows types of populations on the x-axis and percent of balance on the y-axis from 0 to 200 by fifties. Grass = 100. Rabbit = 50.4. Snake = 100. Hawk = 100. a. The snake population will decrease rapidly and the grass population will increase rapidly. b. The hawk population will increase rapidly and the rabbit population will decrease rapidly. c. The grass population will decrease rapidly, and the snake population will increase rapidly. d. The grass, rabbit, snake, and hawk populations will all decrease rapidly.

"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."
