The oceans and seas cover more than two-thirds of the planet and are a vital source for survival. Not only is it a source of food for humans, it is also a source of energy and essential for the absorption of carbon dioxide.
Their importance shows that they must be preserved. But humans are the ones who misuse these resources and endanger the entire marine ecosystem. Most of the oceans and seas are international waters that are not under the jurisdiction of any country that regulates them. In this way, no one can guarantee your protection or care.
Problems in the oceans and seas
Predation, which in most cases is carried out in violation of the law, is one of the main problems. Indiscriminate fishing precedes the oceans and seas. Fishing companies are increasingly investing in larger vessels with industrialized fishing systems. They are the ones that cause the amount of fish to decrease dramatically day by day.
According to marine biologists, there is an excess of fishing boats and a very marked decline in the fish population. Added to this is the death of many marine fauna such as turtles, whales, sharks and dolphins. Some die from being caught in floating fishing nets. Others are victims of indiscriminate hunting for purely commercial reasons.
Other problems arise from the mistreatment of the planet
Another danger is the acidification of the oceans and seas as a result of pollution with carbon dioxide. The oceans absorb most of the CO₂ and carbonic acid is produced. By lowering the pH of the water in the ocean, the concentration of hydrogen also drops, which will harm smaller species in the near future.
As if that wasn’t enough, there is another threat that threatens life in oceans and seas. The water of the oceans has reached a temperature of more than half a degree over the past hundred years as a result of global warming and climate change. This rise in temperature leads to the death of coral reefs and the algae that live in them. As an example, it should be mentioned that 75% of the coral reef in Australia has disappeared.
Plastic waste is a big problem for the oceans and seas. Every year 8 million tons of plastic are thrown into the sea. These residues are deposited as microparticles on the sea floor, which fish often consume with their food. Much dirt is carried away by the various ocean currents and ends up on the high seas. Others, who do not move in the open sea, pollute and pollute the coasts of every continent.
Recycling and circular economy are some possible solutions. Education is paramount. This would enable future generations to be more sensitive and responsible. As marine biologists advise, measures must be taken against all of these threats in order to partially restore the world’s oceans and seas.
