Your presentation does nothing to add to the biofuels and wider greenhouse debate. It, at best, spreads half truths and at worst is completely disingenuous. The arguments used are the same as those of George Monbiot and has been widely discredited as simplistic and overly dramatic.

Whilst it is true that rainforests are being damaged by rapacious over exploitation, biofuel production, on the whole is not the culprit. Its the growing desire for wealth from the developing world that is driving this land clearing. The vast majority of biofuel production does not come from previously virgin rainforest but from other agricultual land (look at rapeseed from Europe, corn and soy from the USA and sugar cane from Brazil which together make up the vast majority of all biofuel feedstocks and do not effect rainforests at all).

And while I agree that this, in the short term, is placing strains on food supplies, this is just a stepping stone. We MUST ween ourselves of the addiction to fossil fuels there is no doubt and biofuels is just one way. The use of food products is a temporary necessary evil in that it helps us learn how biofuels can be manufactured and used. We dont want anyone to stave and to that end, economic rules will prevail! The price of the biofuel feedstock will (and has already) skyrocket and thus create the impetus to develop new feedstocks like algae and jatropha. Check D1 Oils website  http://www.d1plc.com/agronomy.php for example. Once these new feedstocks, which by the way do not use any arable land at all, come on line, food prices will return to their normal levels. The growing "wealthy" population of the world will end up putting the greatest upward pressure on food prices, not biofuels.

And isn't a growing the wealth of the poor and reducing greenhouse gases what we all want?

There is absolutely nothing bogus about the presentation.

Biofuels represents all the worse aspects of our globalised economy. Just as we accept the concept of food chains with lions and polar bears sitting at the top and these chains going all the way down to bacteria and single celled organisms; then so it is with the products that we consume and we have a similar product chain. Those well off individuals in the west exploit the next layer of society down, who exploit the next layer down, and so on. Eventually you reach the very bottom, were you find people and ecosytems with no rights being totally exploited. That is the way it is with our system. To try and pretend otherwise is naiviety. See my blog for the recent NASA pictures of the Amzon burning for biofuel.

Yes the Amzon might be burning for other things, but it is now burning faster than ever before because of biofuels and that is an unavoidable conclusion.

And next time you watch the news about Afganistan and read of th billions it is costing us and the young lives that we are sacrificing, then reconsider that 1.3 million have now moved into starvation due to the escalating prices of staple foods.

What ever way you look at it, Biofuels are the most stupid idea that we have ever come up.
