Beyond the Brink

Got Beyond the Brink by Peter Andrews for Christmas.

Only done a quick skim and read the first two chapters.

One point I've already pick up and agree with is the amount of climate change that is human induced but not due to greenhouse gases. Deforestation, particularly where the amount of tree cover drops below 10% is having a large affect on the local and regional scale that few city people understand and many farmers underestimate.

I think a lot of the lose of rainfall in the Eastern coast and internal of Australia is due to over clearing at the farm and shire level. The most stable rainfall is inevitably east of areas that are protected for some reason or where the country was so 'poor' that agriculture never got established.
