Wow, I just want to say that we have an incredible array of topics covered in the Berkshire Encyclopedia of Sustainability. (Not to toot our own horn or anything!) The usual stuff that you hear about all the time, yes – carbon capture, coal, climate change, etc. – but we have tons of interesting stuff on places like Phoenix that are considered to be among the world’s most unsustainable cities – and yet Arizona State University is among the world’s top places if you’re serious about studying sustainability. (I guess it makes sense: if you want to study a problem, best not to be isolated from it!) Anyway, check out this list of topics – which is only scratching the surface.
