Are Oceans Really That Important?

While you were reading the title of this article, you breathe about 2 times. You will continue to breathe while reading this article.

Here, one of the tasks of the oceans is to produce 70% of the oxygen we breathe in the atmosphere.

It is generally thought that forests and rainforests produce the majority of oxygen. However, while Amazon Rainforests only provide 28% of the oxygen, phytoplankton do a significant part of the work.

The ocean is a global system. In this global system, there is always a heat exchange in water bodies thanks to surface currents. At the same time, the ocean is in a heat exchange with the atmosphere. This circulation has a great impact on climate change. The ocean, which absorbs and distributes heat evenly, helps to slow the effects of global warming and climate change.

Oceans are a major economic resource.

About half of the world’s population live 100 km from the sea and 100 million people live 1 meter above sea level. Fishing, transportation,pharmaceutical industry, biotechnology are dependent on oceans.

The ocean, which is so effective in our lives without us realizing it, is in great danger. In our previous issue, we talked about how big the effects of climate change can be. One of the changes that the oceans are facing today and the effects of which we are rapidly seeing is Ocean Acidification.

Ocean Acidification 

Due to industrialization and human activity, the amount of carbon in the atmosphere is gradually increasing. Ocean acidification, on the other hand, is the increase in the pH of the ocean as it absorbs more carbon in the atmosphere every day. About 30 percent of total emissions have been absorbed by the oceans in the last 200 years. Today, the amount of carbon absorbed by sea water is around 25 percent each year. As a result of the reaction of seawater with carbon, minerals such as calcium are decreasing, while acidity that disrupts ecosystems increases.

As a result of the decreasing basic ions in water, many species such as coral reefs, mussels and plankton are among the threatened species. Marine creatures such as mussels use these substances to produce their outer shells, so it’s getting harder and harder to survive for them. In addition, acidification puts both coral reefs and 9 million creatures living around corals at risk because of its dissolution effect.

We are the people who can solve global warming and ocean acidification, which we discussed in detail in our previous issue.Taking a step to reduce greenhouse gases, producing environmentally friendly solutions in our daily lives are key. Using plastic as little as possible to reduce the amount of carbon and plastic in the oceans is critical for the preservation of the oceans.
