In recent years, we have increasingly heard thatThe environmental situation on our planet has worsened. As the reasons for this, quite a lot of phenomena are called, but all of them are somehow related to human activities. We will not go into specific reasons today, but consider their consequence. Moreover, recently a group of researchers from the National Center for Environmental Analysis and Synthesis of the United States (NCEAS) calculated how people have polluted the oceans over the past decade. And the answer to this question is really shocking.
How much people have polluted the ocean
According to the editorial board of Scientific Reports,A new study by American scientists first assessed where and how quickly the cumulative impact people have on the oceans is changing. Moreover, absolutely everything was taken into account - from pollution by harmful substances to the catch of marine inhabitants. We will not drag out the intrigue and say that the total negative impact of man on the world's oceans is almost 60%. That is, today the ocean is 60% dirtier and poorer marine life than 10 years ago!
This is a big problem, says the presenter.The author of the work is Ben Halpern. Moreover, this problem has many reasons. We cannot just fix one of them if we want to slow down and ultimately stop the growth rate of human impact on the oceans.
Why is the ocean so polluted over the past 10 years
The key factor scientists call changeclimate, namely global warming. It is known to be associated with an increase in greenhouse gas emissions due to the ever-increasing rate of industrial production. Due to climate change, there was an increase in air temperature, which caused the oceans to heat up and acidify. It throws oil into the fire and the growth of fishing for marine inhabitants, which has grown several times in recent years.
Scientists say that if nothing is done,in the future, the situation will only worsen. In the next 10 years, changes will only grow and double by 2029-2030. Regions of particular concern to ecologists include, but are not limited to, Australia, West Africa, the East Caribbean Islands and the Middle East.

However, scientists have some good news (as inour channel in Telegram), which allow us to be more optimistic about the future of our planet. Researchers have discovered that every continent has its own, as they called them, "success stories." These are areas in which the harmful effects on the environment have decreased, which favorably influenced the environmental situation in the region as a whole. In particular, fisheries and water pollution have declined off the coast of South Korea, Japan, the UK and Denmark. And scientists suggest to other regions what is called “taking an example” from the best in order to prevent the development of an environmental disaster.
