I haven't read his new book, but I've read bits of it that were serialised in a newspaper.
Attenborough is a fascinating man and has a lot of interesting things to say.
His new book is about the environment and how to save it, basically.
He wants us to drastically cut down our meat intake and eat more fruit and veg. Nothing wrong with that, but he also wants us to stop using pesticides on crops. This got me thinking. How would that work? If more fruit and veg are to be eaten, we'd need more crops to feed the world's population. Pesticides do help put fruit and veg on our table. Without pesticides, there'd be no guarantee that people would be fed.
I think this is a problem with many who want to help the environment - they don't think of the details. Attenborough begins his book by saying that, originally, humans lived in balance with nature as hunter-gatherers. What this means is that mortality was high, starvation, killed in wars, etc. to keep the population down. This is why we've made such progress.
How we learn to keep the progress we've made and cut down our emissions is another thing.
Everyone breathing breathes out CO2. There is no solution, other than killing billions of people (which is obviously wrong).
