It is said to see the change in the generations. Those from the twenties understood the depression though they were to young to comprehend it and now people need to be shown what is happening in their own communitee on paper for it to be truth and factual. "Cite" the Site is all across America there are fewer operating farms and more houses.
Look at California. What happens when there is a 1" rain storm...the storm DRAINAGE SYETEM takes billions of gallons of water to the ocean. This water would have been absorbed into the ground 100 years ago. So the paved surfaces stop the water from entering the water table. Just a single acre of parking lot will produce approximately 325,000 gallons of run off water. When La is 469 and there is 640 acres in a square mile and over 90% of the city is paved or buildings per the 2010 census study. And if I did the numbers correctly that is 88 billion gallons of water lost per acre of rain. Granted this will only raise Lake Mead about .3 inches but it still increases the affects of the drought.
It is far more important that people learn how to lessen their affect on the plant than to loss ones grasp on reality and predict the disappearance of cities and tens of thousands of acres that was said to happen before 2015 due to global warming. Since this didn't happen the name is now Climate Change. Well guess what as the last several posts have stated the climate is always changing and will long after we are all dead.
Lets spend time more wisely and figure how to stop cancer, diabetes, and any of the other life threatening diseases that need the funds to investigate and find a cure; than flying to a foreign country to have a summit on Climate Change! And when that is moving forward we better fid a way to make our farm land operational again cause we are going to have a bunch more people to feed!
