Talking about aquatic ecosystems, it means that the overall water ecosystems, whether on land, such as rivers, lakes, marshes, and of course the ocean. Trying to understand how they are interrelated to each other, understand each role.
It is important to understand about how the ecosystem work, in order to develop knowledge about how good ecosystem management, gave an overview to make policy, to then be able to take the most appropriate action to protect the aquatic ecosystems.
The water supply is closely related to the life aquatic ecosystems and ecosystem sustainability in a broader sense. Nature has a system and a unique and powerful mechanism to perform its function as a giant water filter and as a means of re-charger reserves of freshwater resources that are necessary for life.
Water stored in the soil in addition to functioning as a backup source of fresh water, also has an important role in maintaining the shape and construction of the land, and to prevent, reduce, or slow the occurrence of abrasion. Excessive exploitation of ground water will trigger the seep of sea water, far into the inland region, and accelerate the decline in soil surface.
Aquatic ecosystems are composed of various components that are inside, such as rocks, plants, animals, micro-organisms, etc.. The existence of living creatures in aquatic ecosystems can be used as a measure of the damage. This is something that really makes sense, when an ecosystem contaminated by pollutants then it will reduce the quality of life of living things in it.
From a few decades ago, the number and diversity of pollutants has increased significantly. These pollutants not only micro-organisms such as parasites, but also heavy metals and synthetic chemicals.
The most dangerous pollutants usually come from plant waste are thrown away without a proper sewage treatment system. Next came the threat of pollutants from transportation and waste from households. In large quantities, the resulting pollutant transport system and household no less dangerous than sewage plant. It is certain that ecosystem damage will occur very alarming.
Ecosystems like a chain of life that are strongly interlinked to form an unbroken perfect circle. And aquatic ecosystems is one part of the chain.
Damage to aquatic ecosystems can be described as the breaking chain of life, and it means a threat to the survival of all living creatures that exist in this world.
It will be recalled that the water is a very important element for the survival of life. When we preserve the aquatic ecosystems, then that means that maintained the continuity of life.
