Environmental Protection Agency chief Andrew Wheeler on Wednesday said that polluted water, drought, and ocean trash are "the largest and most immediate environmental and public health issues affecting the world right now." He made his remarks in Washington on World Water Day, saying he is frustrated because "water issues often take a backseat" to larger discussions about global warming. "Most of the threats from climate change are 50 to 75 years out," Wheeler said. "What we need to do is make sure that the people who are dying today from lack of having drinking water in Third World countries, that problem is addressed."
