Due to chemicals, pollution, toxins, human and animal waste and don’t get me started on fracking there are a lot of people getting sick. 4 Billion case of diarrhea worldwide every year and 2.2 million avoidable deaths…a death every 14 seconds. Most of the world does not have a safe supply of water and in some countries women walk for hours to fetch water. In Jakarta, the poor pay water vendors 60 times the price of water on the standard connection, in Haiti they pay 100 times!
Half a billion people live in countries chronically short of water. By 2050 this is likely to rise to more than 4 billion. The problem is exacerbated by unsustainable depletion of groundwater stock, where nearly all of the world’s available fresh water is stored. 97% of fresh water is stored in these aquifers. They are severely deplete in parts of India, China, the Middle East, the U.S. and North Africa. The world is currently running a groundwater overdraft of 200 billion cubic metres a year.
