The Problems of the World Ocean Pollution Executed: Prontsevich Mikhail DS-3 Solidarnosty 11 -1
Generations leave and new inhabitants of the planet are born. Only the World ocean remains static and unchanging. Humanity could not find anything better how to dump industrial waste and various garbage.
What occurs in the ocean? Pollution has already led to a violation of the marine ecosystem. A lot of animal species have already disappeared, and we didn't notice that…
THE FISH INCLUDED IN THE RED BOOK
est arg he l ish T f Whale shark - the largest fish in the world. It length reaches 14 m, and more than 12 tons weigh, it is more, than 10 cars. Its colour is very funny - white spots on the blue green huge nose.
Black bream Life expectancy about 10 years.
Oil and oil products Oil is the most dangerous and widespread pollution of the ocean today. About ten million tons of oil is dumped in the ocean annually.
Chemicals The chemicals get to this huge reservoir in various ways. They also have a very negative impact on ecosystems… Pollution with pesticides of the oceans is especially dangerous, they can collect in the tissues of living organisms.
Heavy metals Extreme concern to ecologists, the pollution of the World Ocean with heavy metals. Such heavy metals as lead, cadmium, copper, nickel, arsenic, chrome and tin belong to the most dangerous. So, now annually about 650 thousand tons of lead get to the World Ocean.
Thermal pollution Thermal and nuclear power plants act as the main sources of the warmed-up waters. Thermal pollution of the Oceans leads to violation of its thermal and biological balance, impairs the reproduction of fish, and also destroys zooplankton.
waste water Pollution of the World Oceans with sewage is the second harm. Waste from chemical and metallurgical companies, textile and cellulose factories, and also agricultural complexes are the most dangerous. First, they merge into rivers and other reservoirs, and then fall into the World Ocean.
fishing We have learned to catch inhabitants of the seas and the rivers well. Through industrial systems there pass millions tone of sea water. For the last hundred years the mankind destroyed an ecosystem which the planet grew up for us thousands of years.
POLLUTION OF THE WORLD OCEAN Plastic is just the monster of the twentieth century. Getting to the rivers, and then to the ocean it becomes a disaster. A lot of plastic Islands are formed In the ocean and for this reason, the sea creatures often die.
CREAM FOR SUNTAN THREAT TO SEA INHABITANTS There are creams which we apply on skin not to be burnt, very dangerous to inhabitants of coral reeves. It would seem how much we apply it on skin? Absolutely slightly, but every time after bathing. Seven billion people do it, even if do not all bathe. Impact on the ocean enormous.
Ecological disruptions Without understanding and without realizing up to the end what can lead our influences to, we moved to the next century. Of course, we don't see the perishing coral reeves, disappearing animals, seaweed. We think that it is far from us and doesn't influence our life. But all processes on Earth are interconnected.
The problem of the World Ocean will not be solved by any country alone. It is important to join together to solve these problems, not only on paper.
For myself I have decided that I will try to throw out garbage to special places, to use less the washing liquids for preservation of purity of water. It is my small contribution to case on clarification of the planet.
