If we gave up eating beef we would have roughly 20 to 30 times more land for food than we have now.
Sadly, it's much easier to create a desert than a forest.
China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution.
Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year.
There is little evidence that our individual intelligence has improved through recorded history.
Fudging the data in any way whatsoever is quite literally a sin against the holy ghost of science. I'm not religious, but I put it that way because I feel so strongly. It's the one thing you do not ev...

If it hadn't been for the Cold War, neither Russia nor America would have been sending people into space.
I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.
If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that, but it's got all the sort of terms that religions use... The greens u...
There aren't just bad people that commit genocide we are all capable of it. It's our evolutionary history.
I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change. The inertia of humans is so huge that you can't really do anything meaningful.
One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You ite...
What I like about sceptics is that in good science you need critics that make you think: 'Crumbs, have I made a mistake here?' If you don't have that continuously, you really are up the creek. The goo...
You mustn't take what I say as gospel because no one can second-guess the future.
I'm a scientist, not a theologian. I don't know if there is a God or not. Religion requires certainty. Revere and respect Gaia. Have trust in Gaia. But not faith.
