Saving the Oceans

The world of the sea shelters a considerable portion of the terrestrial biomass, in the most various forms. Genuine "biological pump", the sea plays an essential part in the regeneration of our atmosphere. But by an always increasing production of waste, the overexploitation of ecosystems among the most plentiful of life and a concentration of our cities along the coasts, we caused a considerable degradation of marine ecology. Many are the aggressions which we subject to oceans:
1. chemical pollution: it comes from the degasification of the boats, the shipwrecks of tankers and other ships in charge of toxic substances, and discharge of industrial waste water. 2. pollution of the organic type: it consists in particular of the discharge of waste water either in the rivers, or directly at sea. The eutrophication of coastal water which results from it contributes to the expansion of certain species to the detriment of others. 3. the genetic pollution: it results from the accidental introduction of species into zones where they constitute a threat by upsetting ecological balance. This form of pollution can cause a worrying reduction of biodiversity. 4. fishings are another aggression: the exploitation of the animal resources of seas is reaching its limiting point today, while the number of fishermen and the capacity of their working tools increase. The human concentration along the coasts and the disorganization which affects our poorest countries amplify these phenomena of depopulation of the oceanic funds. The power of the ocean and its resources are less than one had supposed a few decades before. This observation takes humanity with opposite course in her race with the oceanic richnesses. The solutions with all these evils can be easily conceived, but apply with difficulty. Already requiring an enormous political pressure in the developed Occident, they run up in the Third World against the socio-economic disorganization, the lack of means or the other urgencies that are facing these countries. However, even if their application remains a pious wish, the agreements, compromises, regulations and international quotas of production remain the best hope of "reasonable" evolution for the situation of the oceans.
