I think it could be interesting for the forum to answer the questions. I'll start.
Safe to eat genetically modified foods? I would say yes with a nod to MP-Ryan, I remember the talk he and I had about GM food.
Favour use of animals in research? Depends on the research. For medicines and anything else important to living, I'd say yes. So girls can pretty themselves up with new makeup, no.
Safe to eat foods grown with pesticides, I'd say yes, broadly speaking.
Humans have evolved over time, yes.
Childhood vaccines such as MMR should be required, first impulse is to say yes, but really this should be something there shouldn't need to be a mandate for. It should be something everyone wants to do. And the problem with there being people on the fence or thinking it's a bad thing is if they are forced into doing it, then that can kind of make them think it's even more of a bad thing if they have to force you to do it. If I have to answer yes or no, I'll answer yes, but I would hope there would be no need to force such a thing if people were just educated enough to understand that it's the right thing to do. That still leaves your faith healers though even if you get rid of those fearing things like it causing autism or causing the very disease it's supposed to prevent.
Climate change is mostly due to human activity, yes.
Growing World population will be a major problem, yes, it will eventually if it keeps growing.
Favor building more nuclear power plants, I'd say only if renewable energy sources aren't going to cut it. I don't really have a strong opinion on it, but just one nuclear disaster does so much damage, ideally we would not have to rely on nuclear power.
Favor more offshore drilling, no opinion.
Astronauts essential for future of US Space program. I'm guessing this means astronauts vs robots going on missions? I don't really know, and neither do the public or the scientists judging by the 47-59 split. Right now a human is going to be more effective and versatile than any robot, but that could change. Especially in terms of sending a robot where a human, even in a spacesuit, can't go. Unless I have not understood the question, I don't see why we have to choose. Robots and astronauts both have their place.
Increased use of bioengineered fuel, yes, if we can.
Increased use of fracking, I don't have the facts to form an opinion on this. I see it in the news and know it's a controversial thing, but I don't know why.
Space station has been a good investment for the US, I don't have the facts for this either.
