"The United Nations World Summit on Sustainable Development is being called a last chance for the international community to set a reasonable course on environmental protection, or face the possible collapse of the planet's ecosystems." (from Radio Free Europe). Although the article is vague, it seems to attribute this "last chance" language to Nitin Desai. When the "last chancers" are proven wrong again and again (things get worse, things get better), doesn't this rhetoric start to seem ridiculous?
