David Helvarg presents 50 Ways to Save the Ocean, practical, easily implemented actions everyone can take to protect and conserve the ocean. The book also looks at toxic pollutant runoff, protecting wetlands and sanctuaries, saving reef environments, and replenishing fish reserves.
Bio
David Helvarg
David Helvarg has devoted his life to the world's oceans and the people who depend on them. His memoir, Saved by the Sea, is the remarkable story of his career both in activism and journalism, where his fight to save the oceans has become a visionary and at times all-consuming cause.
This eloquent and honestly told tale of the changes in one man's journey and the world's oceans over the last half-century is also a profound, startling, and sometimes surprisingly funny reflection on the state of our seas and the intimate ways in which our lives are all linked to the natural world around us.
Helvarg is founder and president of the Blue Frontier Campaign, a Washington, D.C.-based organization working for ocean and coastal conservation. An award-winning journalist, he has written for the New York Times, the Los Angeles Times, Smithsonian, Popular Science, Sierra, and The Nation, and has produced more than forty documentaries for PBS, the Discovery Channel, and others. His previous books include The War Against the Greens, Blue Frontier, 50 Ways to Save the Ocean, and Rescue Warriors.
Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution. In 2007 the UN Intergovernmental Panel on Climate Change forecasted that by 2100 global average surface temperatures would increase 3.27.2 °F (1.84.0 °C), depending on a range of scenarios for greenhouse gas emissions, and stated that it was now 90 percent certain that most of the warming observed over the previous half century could be attributed to greenhouse gas emissions produced by human activities (i.e., industrial processes and transportation). Many scientists predict that such an increase in temperature would cause polar ice caps and mountain glaciers to melt rapidly, significantly raising the levels of coastal waters, and would produce new patterns and extremes of drought and rainfall, seriously disrupting food production in certain regions. Other scientists maintain that such predictions are overstated. The 1992 Earth Summit and the 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change attempted to address the issue of global warming, but in both cases the efforts were hindered by conflicting national economic agendas and disputes between developed and developing nations over the cost and consequences of reducing emissions of greenhouse gases.
Does that mean that in several million years the whole planet will look like a department store display at Christmas time, with fake plastic snow all over everything?
