Pros and Cons:

	Pros	Cons
Agriculture	·  Might actually make agriculture easier and more productive, resulting in more food/healthier food ·  Could help to make getting meat less painful and more plentiful, causing in less deaths and gruesomeness	·  The food might be dangerous to eat and might pass on the genes to future generations ·  According to some tests, some types of foods can cause those who eat it to be infertile
Medicine	·  Can help to make new discoveries in the medicine	·  The medicine might not work on humans if it only works on different animals ·  If animals are modified to be sick, it causes unease because so many animals would die from that
Endangered species	·  Can help to re-introduce endangered species and make them more likely to survive	·  The endangered species, if modified, might be dangerous to their territory like invasive species
Research	·  Research could work and we could have a break-through	·  The research could prove to be false
Donating Organs	·  More organs= less deaths	·  The organs might not function properly or be damaged ·  The person could feel uncomfortable with having, for example, a pig liver ·  The organs might cause different changes in the humans

Overall, I believe that the pros and cons are about equal. While there might be more cons, the pros can lead to revolutionary things.
