He said that developed countries should create a fund to compensate the countries of the Amazon basin for generating oxygen. He argued that oxygen is "a priceless good," but the industrialised world should compensate the Amazonian countries because the oxygen they produce "benefits the entire planet." The compensation payments could be used to conserve the Amazon region, or to pay back creditors.
He said it was not fair to provide the world with oxygen for free, when agricultural machinery imported from rich countries is so expensive.
