Worrying Pattern of Oxygen: We Risk even more Worrying Patterns if Oxygen Supply Continues to Decline

Today, oxygen in most of the world's oceans rapidly decreases, the rate of decline put at two percent since the 1950s, some part of the tropics showing as much as a fifty percent reduction, with computer models estimating that global oxygen concentration may decline by seven percent by the year 2100.

While this happens, oxygen availability in the world's great cities shows imbalances, with urban areas of only 3.8 percent of the global surface accounting for 39 percent of terrestrial oxygen consumption between 2001 and 2015, their oxygen index greater than 100.

Meanwhile, the oxygen in the atmosphere shows alarming decline, the rate having speeded up over the past 100 years at 0.10 percent, compared to 0.7 percent in the past 800,000 years. 

Oxygen gives cells in the human body the ability to break down food, in order to provide the energy needed for survival, but it shows a reduction in water bodies, atmosphere, and cities, raising serious questions about the future.

The oceans store more than 93 percent of the earth's warming from climate change, but the higher the temperature of water the less soluble oxygen becomes, leading to  low-oxygen water to increase by 4.5 million square kilometers in the open oceans and over 500 low-oxygen sites in coastal waters, including estuaries.

The major cities on a worldwide basis experience about 12 to 17 percent of oxygen content when it dips down to earth, 19 percent at places of pristine nature, and 21 percent during prehistoric times, the imbalance today escalated by climate change.

The atmosphere lost 0.10 percent of its oxygen in the past, brought about by the burning of fossil fuel and deforestation, triggering climate change, activities that also made oxygen on the global level to plunge.

Oxygen enables living things to survive in their various environments, but climate change powers its decline in the atmosphere, water, and cities, making people ask serious questions about this development.

By 2080, about 70 percent of the world's oceans could be choked through the reduction in amounts of oxygen, while the average annual mean dissolved oxygen could create problems, as experts project the figure to decline by 1.5 to four percent by 2090.

By 2070, around 3.5 billion people could live with average temperatures in the mid 80s, while the decline in oxygen production could create further challenges, especially as the situation implies that humanity would be living outside its comfort zone.

By 2100, about three to four percent of oxygen could be lost in the oceans at the present rate of carbon dioxide emissions, while the decline in oxygen production could be worse in the waters of tropical regions, with much of the loss expected in the 1,000 meters of the water column, which could affect biodiversity.

Oxygen, of course, enables the survival of species in the top 1,000 meters of the water column, cities, and the atmosphere, but  shortage through climate change from 2070 to 2100 could prove dangerous, a development that gives rise to thoughts related to the solutions to the crisis.

In the 1960s and 1970s, the River Thames in England bounced back in terms of oxygen production, when the English authorities treated their waste water for the removal of chemicals. In the 1990s and 2000s, researchers stationed floats numbering 4,000 in the open seas, gathering data about low-oxygen events, leading to quicker responses to the problem. In the last few years, renewable energy increasingly replaced dirty fossil fuels with wind and solar energy generation. 

Oxygen Supply shows reductions, but through waste water treatment, the gathering of data, and the use of solar and wind energy, its generation could improve in water, atmosphere, and cities.
