And today is Earth Day. Millions of people around the globe are expected to take part in events honoring the protection of the environment. A new report from the Oxfam aid agency warns relief groups will be overwhelmed within the next six years by people affected by climate-related disasters. More than 375 million people are expected to be affected each year until 2015, up from the 250 million people today. Oxfam is calling for greater support for aid groups to offset the dangers. Oxfam says, “There is nothing inevitable about a future in which greater numbers of people die and are made destitute by natural hazards and conflict.”
