Endangered Species Up The Risk Of Extinction For Other Species In Ecological Community: Theoretical biologists at Linköping University and the University of Sheffield have demonstrated the codependency of natural creatured by showing that threatened species put their neighbors at risk.

Brazil warns EU on green biofuel controls: The battle over biofuels continues to heat up. Members of the European Union are talking about restrictions on biofuel imports which don’t meet certain environmental on social impact standards. Unsurprisingly, biofuel-exporting nations are raising a fuss over the idea. Andre Aranha Correa do Lago, head of the Brazilian Foreign Ministry’s energy department, told reporters Friday that his country’s biofuel program has no negative impact, and he’s planning to bend a few ears in Brussels to underline up his claims.
