Do you think that with the use of science, we are interfering with the "plan"?

By "plan" i mean what is meant to happen..if ur religious - what has god planned or even a fate believer..should we leave things alone? like not modify and fuse animal and human dna etc? or should we use our so called developed brains to "succeed" in life? are we succeeding or becoming more insane and materialistic?
Answer
I think some things should not be messed with. like cloning animals and giving them things they were not meant to eat. when i found out that the farmers were recycling their pig fetus it really made me sick. when they gave the cows parts of bones, etc. from other animals this was not their diet and of course something came out of it, mad cow. i think they should not mess around with living things in such a way that they change their normal way of eating, etc. i think now they are playing god when they try to recreate life on their own. something bad will come out of it. now they are talking about us eating cloned animals and they have already changed the makeup of plants to sell to us for food. what next? i fear that they are just going too far and it will be society that will suffer for it all.
