Climate change and the discharge of nutrients threaten the oxygen levels in the oceans.
this is the sound of the gloomy forecast in a new report.
It is bad news for fish, such as tuna, marlin, and certain types of sharks, while it promises glory days of vandmændene, writes the BBC.
It is IUCN, the International Union for Conservation of Nature, an organization of 1300, both governmental and non-governmental organisations from all over the world, which is behind the so far largest study of the oceanic state.
the Report has just been presented at the united Nations climate summit in Madrid.
Denmark is among the world wide fund for nature, the Danish society for nature conservation and the Environment and Food members of the IUCN.
"If we run out of oxygen, it will mean the loss of nature, loss of biological diversity. It is a slippery slope towards the slim and the more jellyfish," says Minna Epps from the IUCN.
While it has been known for decades that the discharge of kvælstoffer, from, among others, agriculture and businesses, creates oxygen depletion in the water, so predict researchers now that the climate change accelerator iltmanglen further up.
While in the 1960s were 45 sea-places that had problems with oxygen depletion, as there is today mapped the entire 700 places, where oxygen levels in the oceans is so low, that animal and plant life suffer.
the Problem is that we emit more carbon dioxide than the plants, the sea and nature can record, it leads to the greenhouse effect. The more greenhouse gases, the more heat, causing the average temperature to rise on Earth - it gives climate change.
When the temperatures rise, the oceans, which absorb the heat, but the warmer the oceans become, the less oxygen they contain.
do we not get to grips with climate change, it is expected the oceans of the world have lost three to four per cent. oxygen concentration in 2100, according to the researchers forecast.
we Will have to keep track of iltsvindet, is the council from the report are the following:Restrict the emissions of greenhouse gases.Get a handle on emissions of nutrients from agriculture and businesses. Updated Date: 09 December 2019, 02:00
