In 2025 between 2,700 and 3,200 million people have no potable water

According to studies, the existing oil will run out within 37 years to keep current consumption

The disproportionate increase in world population has been reported as a major environmental problem the planet on the third day of the course "Water and energy : technological challenges of the third millennium," Summer School Foundation Engineering and Society. Remained so Julián Blanco Gálvez , a researcher at the Plataforma Solar de Almería , European Award for Innovation 2004. According to the scientist, "the water in the world is stable, but the population grows exponentially in a way. We've gone from 500 million people in 600 to 2,000 million people in 1930, then to 4,000 million in the year 1976 and now we are 6.673 million human beings. The main problem with water is the number of existing people. To continue and the growth of the human race and made no quick solutions in 2025 will not have potable water between 2,700 and 3,200 million people. "
Julian White based his defense of alternative energy, especially the sun, on concrete facts, "according to studies, the existing oil will run out within 37 years to keep current consumption. In fact the price increase we are experiencing is due to being exhausted. Oil will never be cheaper than now. The only option is that before 2020, when it will have reached global peak oil production, solar energy is strengthened, which is useful not only as a source of energy, but also serves to clean water where no water drinking. "
coordinator The Economic Analysis of the DMA from the Ministry of Environment and Rural Josefina Maestu alerted engineers participating in the course: "Most of the groundwater in most of Spain is in a delicate situation, or is not good enough, or is overused." For the future raised the need to value water in economic terms, "we need to know the performance of one cubic meter of water on a golf course, a tomato farm and a Campot barley. Must see how the added value of water in production processes to decide what measures we take, what kind of society we want. "
Tomorrow, Thursday July 10 will be held the fourth day of the Engineering Foundation Course, and Society at Expo Zaragoza.
