Do you guys Believe this is a true fact or not?

I was talking to my aunt from the Dominican republic and she said that the problem with America is simply that we experiment with to many things, alot of the things we experiment with isn't necessary. One example of a unnecessary experiment is that whole Liger thing that wasn't necessary (combination of tiger and lion) alls that did is create a new species that is eventually going to be extinct because there is only one. Many countries have mass amount of bugs and insects but still manage to have good fruits and vegetables Americans contaminate it. Do you agree with this? I personally do. Give your honest opinions and if You know of any more unnecessary experiments feel free to tell. Please and thank you.
