In recent years, we have increasingly heard that the environmental situation on our planet has deteriorated severely. The reasons given for this are a whole series of phenomena, all of which are in some way related to human activities. Today we will not deal with concrete reasons, but consider their consequences. In addition, a group of researchers from the United Nations National Center for Environmental Analysis and Synthesis (NCEAS) has recently calculated how people have polluted the oceans in the past decade. And the answer to that question is really shocking.
How many people have polluted the ocean
According to the Editorial Board of Scientific Reports, a new study by American scientists has for the first time examined where and how rapidly the cumulative impact of humans on the oceans is changing. Absolutely everything was taken into consideration – from the pollutant load to the catch of the sea dwellers. We will not drag out the intrigue, saying that the total negative impact of humans on the oceans is nearly 60%. That is, today the ocean is 60% dirtier and poorer than 10 years ago!
This is a big problem, says lead author Ben Halpern. In addition, this problem has many reasons. We can not just fix one of them if we want to slow down and ultimately stop the growth rate of human ocean impacts.
Why has the ocean been so polluted in the last 10 years?
The key factor that scientists call climate change is global warming. It is known that greenhouse gas emissions are increasing due to the ever-increasing rate of industrial production. Due to climate change, the air temperature rose, causing the oceans to heat and acidify. It throws oil into the fire and the growth of marine life, which has grown several times in recent years.
Scientists say the situation will only worsen in the future if nothing is done. In the next 10 years, the changes will only increase between 2029 and 2030 and double. Regions of particular interest to ecologists include Australia, West Africa, the East Caribbean Islands and the Middle East.

However, scientists have good news (as in our channel in Telegram) that allows us to look more optimistically into the future of our planet. Researchers have found that every continent has its own "success stories." In these areas, the harmful effects on the environment have decreased, which has had a positive impact on the environmental situation throughout the region. In particular, fisheries and water pollution have declined off the coast of South Korea, Japan, the United Kingdom and Denmark. And scientists propose to other regions to take an example of the best in order to prevent the development of an environmental catastrophe.
