A. Environmental issues can be very controversial. There is a lot of propaganda that we should be skeptical of. Studies on the environment funded by grants from the government and science foundations are very lucrative for scientists, and we must never think that scientists are above being as totally depraved and sinful as anyone else. I have a degree in Environmental Studies, knew many environmental scientists, and remember them spending much of their time brainstorming about how to get grant money. And, although scientists would like us to believe that they approach a problem with neutrality, we should always consider whether a scientist’s conclusion is influenced by his politics. I am not saying that everything you read about various environmental crises is a lie. Nor am I trying to apply a broad brush to environmental scientists that paints them all as money-grubbing con artists. But I am saying that, as with anything, what we read about environmental issues should be viewed with a skeptical eye.
