its true that all media (even the sun

) have their own 'views' on topic which manifests itself as an agenda. Facts get reported differently highlighting negative rather than positives for example.
That other great bastion of facts http://en.wikipedia.org/wiki/Agriculture#Environmental_impact suggests that 43% of the worlds land area is used for agriculture but mostly cattle.
This is the UN report
http://www.virtualcentre.org/en/library/key_pub/longshad/A0701E00.pdf
Says 26% in the report?! This is non-ice cap maybe Russia is considered perma-frost?
Although I am not a vegetarian surely one of the problems is the inefficient use of land for producing meat rather than fruit and vegetables? Worse than that:
It is one of the largest sources of greenhouse gases—responsible for 18% of the world's greenhouse gas emissions as measured in CO2 equivalents
I don't have the
facts to hand but even bio-fuels are not carbon neutral. The carbon required in producing them will add to the problems we have though I would imagine at a slower rate than mineral oils. However, changes in land use can have un-predicted effects on the environment. What would happen to the worlds eco-system if 50% of 'huge' Russia became intensively farmed? Where would all the water come from? I start thinking about space mirrors and directing light at this point and go all Star Trekky...
