Lester R Brown has wrote this book which has been published free of charge as a pdf to download. It is simply a full scale plan to 'cure' the earth and save civilisation. He poses possible solutions for climate change, fossil fuel depletion, poverty, famine and disease. It has recieved fantastic reviews and I am in the process of reading the pdf myself. Thought I would post it here as it is totally free and looks a great read.

Cool thanks for this

Just a post to point out this would be a good point of reference to anyone doing any sort of earth science classes at school - The natural systems chapter would have supplemented my systems thinking unit am I will be informing my lecturer of this as soon as school resumes.
