Preventing water pollution is critical to protect future of agriculture. There is no agriculture without water. Fresh water runs into the ocean and once it’s there, it can’t be used anymore to grow crops. Unfortunately, draining off water without treatment is one of the most important causes of pollution, in particular in non-developed countries where agriculture is critical for the survival of the population.
Everybody drinks water… Humans depend on water, more than they depend on food. The quantity of water we require to generate meat is much higher than the quantity needed to grow vegetables or cereals.
Not treated waste water is also responsible to the increase of toxicity in the soil. This is terrible to our agriculture and availability of farmland. On the other side, wet waste can be used as fertilizer if properly treated, minimizing also the volume of inorganic wastes that are sent to the oceans everyday.
Pollution caused by sewage water is just one of the problems. Radioactive pollution is quickly becoming a significant concern, despite the efforts to reduce usage of nuclear energy. Environmental pollution is a wide concept including pollution of various biological and physical parts of the planet with a consequence for human life.
