The ocean is vast but most of the area has been invaded by humans.

Thirteen percent of the world's ocean area is considered to be untouched, they are waters undisturbed by human industrial activities.

We often know a lot about protected natural areas and help avoid human impact, but there are few documents that study similar conditions in the oceans.

In the latest study published in Current Biology, scientists have identified the most pristine waters, not directly affected by humans, and the marine ecosystem is free. development, accounting for only 13% or about 34 million km.

The map of the seas still retains the pristine scenery beside the seas that have been impacted by humans around the world.Data: Kennedy Elliott, Ng Staff;Kendall R. Jones, Wildlife Conservation Society.

In these places, the ocean is still preserved intact as millions of years ago. It is not surprising that these waters are too far away from the residential areas, making them unreachable, such as the distant seas of the Earth's north and south poles. The waters near the coastline of the countries, only 10% are preserved in pristine condition and 5% of them are protected by countries.

Although this can be easily speculated, but Kendall Jones' research has shown the data, he is the author of the study and expert on natural conservation planning at the World Conservation Society. Wild. Accordingly, the fishing industry has made people go further into the ocean, and adversely affect the marine ecosystem at the place they go through.

Through this research, he expects that the seas that remain untouched will at least keep it that way. Further, he hoped countries would plan and set up protection zones to preserve their national waters from the impact of mass industrialization.

The seas contain 97% of pristine waters around the world.Data: Kennedy Elliott, Ng Staff;Kendall R. Jones, Wildlife Conservation Society.

The polar waters are preserved in a very primitive state because few people live here, but they are still indirectly threatened by human industrial activities. When extreme environment changes lead to global warming, the ice in the two polar regions will melt and change the waters here.

Researchers have looked at the 15 factors that affect the ocean made by humans, such as fishing, pollutant discharge, nutritional degradation in the sea, as well as variable activity. climate change, acidification of the ocean .

Pristine waters tend to be more biodiversity and biological genetics than other seas . However, these places will be vulnerable to human encroachment because they have never been exposed to artificial negative effects.

'Looking at this map, we should appreciate the unspoiled little wild seas. Once devastated by humans, they will be hard to restore as they were, so protect the clean waters of human industrial impacts , 'said Kendall Jones.
