and intersting counterpoint to biofuels is also here - Forget biofuels - burn oil and plant forests instead
There's an interesting little quote I'd like to take out for you from the current New Scientist mag:(hope you don't mind me posting this here. Did not want to open a new thread specifically)The latest planetary health assessment shows we need 1.l4 Earths to sustain the average lifestyle. The UN Environment Programme released its fourth Global Environment Outlook (GEO) report last week. And while the human ecological footprint is 21.9 hectares per person on average, the Earth's biological capacity is just 15.7 hectares per person.According to the Global Footprint Network, we went into ecological debt on 6 October this year, having consumed more than the planet can regenerate in one year. Similar footprint calculations recently found that Cuba is the only nation developing sustainably.About half of our footprint is accounted for by the areas that are required to absorb our greenhouse gas emissions, says Neville Ash of the UNEP World Conservation Monitoring Centre in Cambridge UK. Theother half is theland which produces our food, the forests which produce our timber, the ocean and rivers which produce our fish.The inflated size of our footprint is partially the result of the growth of the human population. Currently estimated at 6.7billion it could reach 8-10 billion by 2050. Ash says we could sustain the current and projected population if we all lived sustainably, the question is how?Article titled 'We'd like another half a planet please' by Catherine Brahic
