Gulf of Mexico's oxygen devoid 'dead zone' could hit near-record 8,000 square miles
A major factor is over population of the human species and the over farming of the top soil, burning out the natural nutrients in it. thus non natural Fertilizer must be used in its place to feed the masses mouths of earth us . so if we dont cuting back in food production our oceans will start dieing and nature will cut us back on its own terms, https://www.dailymail.co.uk/sciencet...lf-Mexico.html
'A major factor contributing to the large dead zone this year is the abnormally high amount of spring rainfall in many parts of the Mississippi River watershed,' the National Oceanic and Atmospheric Administration said in a news release Monday.
That led to record amounts of water carrying large amounts of fertilizer and other nutrients downriver, it said.
The nutrients feed algae, which die and then decompose on the sea floor, using up oxygen from the bottom up in an area along the coasts of Louisiana and Texas.
