If you're looking for an introduction to the climate crisis, this is an excellent one. I've always watched and loved Attenborough's documentaries, and this book is no different (there's a feature film with the same name "A Life On Our Planet", if you'd prefer that). 

I love nature. I love learning about animals and plants and their complex ecosystems. 

David mentions one particular phenomenon called the "shifting baseline syndrome". Basically, each generation defines normal by what it experiences, we judge the natural world as we see it TODAY. 

We look at all the beautiful wilderness; the oceans, rain forests, savannas and all the creatures thriving within them and we think it majestic, infinite. But we forget that mankind has obliterated most of the wild, and what's left today is but a tiny fraction of what it had been. 

We don't understand what we're missing. 

And that's a sad thought. 

(This is a hopeful optimistic book btw, regardless of my review😂)
