One has to listen to our wise ancestors: they knew how to build relationships with nature and accept themselves as part of it. The sea pollution that is present today not only creates environmental problems but also damages human health.
Nature gifts us plentifully with so many things, but it depends on us what our children will get. The main task here is to draw attention to existing environmental issues, in particular damage to water resources. It is necessary to share knowledge, learn, train, and open wide one’s eyes and hearts.
Nowadays, progressive water pollution is a question of great concern. The sources of pollution are numerous and the most harm is done to fish, among other water inhabitants.
Fish saturates the body with the most valuable fatty acids: the linoleic and the arachidonic (famous Omega 3 and Omega 6). They are important for normal metabolism and are also the building material for cell membranes. Omega 6 reduces the level of harmful cholesterol in the blood and minimizes the risk of atherosclerosis, having a beneficial effect on the work of the circulatory and cardiovascular systems. High content of phosphorus in fish affects the healthy work of the nervous system, increases efficiency and eliminates fatigue.
Every year the waters of the rivers, streams, seas, and oceans are increasingly polluted by waste from the chemical industry. Thus, a tendency of increasing amount of arsenic in ocean waters was observed. The ecological balance is damaged significantly by heavy metals such as lead, zinc, nickel, cadmium, chromium and copper.
For these and many other reasons, the same fish, which has always been considered a staple of healthy nutrition, now contains metals, industrial chemicals, pesticides or parasites that can harm us.
Fish and mollusсs accumulate heavy metals; lead and mercury are the most widespread. Long-lived and upstream fish types such as sharks, tuna, king mackerel, and others contain a higher concentration of mercury than other species.
When scientists researched the level of contamination of fish, mercury was found in all fish species subjected to testing. More than 20 percent of these fish contained mercury in concentrations exceeding the safe levels for people who eat fish on a regular basis.
That is why there is an increasing call for sustainable fishing these days. So what does it mean? It means leaving sufficient fish in the ocean, which ensures a community of fishers have enough healthy fish without damaging the marine environment. They should also ensure the long-term health of their resources.
The sustainability of fishery standards must be based on scientific research, and include at least these three main principles: minimize environmental impact, keep enough fish in reserves and manage fishery effectively, obeying the law and preventing illegal fishing. The fish populations must remain healthy and active.
Fishing must also be managed carefully so that other species within the ecosystem are not harmed. It is also very important to have enough flexibility, to quickly adapt to changing environmental conditions.
The achievement of sustainability is an ongoing process, which needs to be improved all the time by developing new ways of protecting marine resources for our future generations based on new scientific knowledge.
We have to learn how to think ecologically! Nature itself tells us that we need to start doing it as quickly as possible.
“People still do not understand that a live fish is more valuable than a dead one, and that destructive fishing techniques are taking a wrecking ball to biodiversity.” Sylvia Earle
