"A warming climate already contributes to disease and early deaths worldwide, as populations experience greater risks from extreme weather events, poor air quality and infectious disease.
The World Health Organization estimates that 150,000 people die every year from the effects of climate change, and millions more suffer from illness, malnutrition and other health problems due to a warming planet."This is from a report done by the Environmental Defense Fund. The report also looks at how prepared the United States is for such disasters and their consequences. The findings show that even the U.S. is nowhere near prepared for numerous, large scale disasters, just look at Hurricane Katrina. If the U.S. is not prepared, how well do you think the rest of our world is doing?
