The green emergency on blue gold is a quantity and quality issue. The availability of drinking water decreases and today it is increasingly polluted and contaminated.
From the point of view of quality, sewage and industrial waste (discharged for 90% and 70% directly into waterways), pollute lakes, rivers and seas. While quantitatively is alarming the fact that two billion people do not have water because they live in places where the availability of this is poor.
Speaking of water, we must see another emergency green: pollution of our oceans.
When you speak to oceans comes to mind of people dream landscapes, poets in the sea, and sometimes you do not think what the oceans have become open dumps. The role of the oceans in the Earth’s water cycle is very important since they water evaporates and rises into the atmosphere and then fall to earth as precipitation, and finally back to the seas through rivers. The oceans are also huge reservoirs of heat that absorb the energy radiated by the sun and release it slowly.
The management and the use of blue gold has becoming more and more weight in the great political and economic decisions.
