Throughout Earth the world known WWF organization proposes working with local fishers to incorporate measures to protect the fragile environment of aquatic life as well as establishing a network of community fishers so that they can take a more active and informed role in making decisions at the regional level about the management of aquatic resource.
Once one will see the example of Mekong River Basin and the ways on saving aquatic life over there, he can easily apply the rules of saving water basins by WWF to any other example. For instance, such factors like rich spawning grounds for the abundance of aquatic life, destructive fishing practices, the construction of hydroelectric dams and the diversion of water threaten the river's integrity, reflecting the situation of the whole world left. Degradation of soils, which are vitally important for human life, is not a rare thing nowadays. Regretfully, dams devastate rivers, which, in their turn, are the source of life both for soil and every other component of our life.
If a question of what can be done to stop destruction of the world we live in, the number of decisions on this topic will appear. The first decision concerns the constraints of aquatic like consumption. The second involves limitations or refuse from destructive actions like the expanding network of dikes and roads, altering the natural hydrologic process, disrupting the regular replenishment of agricultural soils and fish yields and potentially contributing to the ever increasing severity and frequency of the floods. The third but not the least in importance in regards to saving of aquatic life is stopping deforestation in all the water basins, which leads to increased erosion of the land and a build up of sediment, which fills the deep pools and changes the aquatic habitat. People should understand that deforestation profits are nothing in comparison of dismal prospects of worldwide self-destroy.
Any aquatic ecologist of the world, being asked, would respond you that aquatic fauna has played a major role in the lives of the people settled along water banks and on floodplains, providing an abundance of fish and freshwater for thousands of years. It is a pity that nowadays the historic role of water is being preferred to the race of earning more money by means of modernization. It is well-known that even the milliard population of the Earth would have felt no hunger and poverty at all if for proper and even distribution of all the resources available. Moreover, the manhood would prosper a lot without making much harm to surroundings.
Aquatic life is a must for the most people's food and livelihoods. Despite its eminent importance, the rich diversity of aquatic life is comparable with mining industry or agricultural one, but shall we eat iron ore? Is there a chance of humanity survival without water at all? Once you have a look at laying waste of tropical forests or broadening borders of deserts of the world - you will see the irreversible changes the little groups of humans can do.
