Burning too much fossil fuel, humans are eroding Earth's oxygen source

The fact that people burn too much fossil fuels to serve electricity production and life activities are unintentionally causing the oxygen (O ₂ ) in the atmosphere to decline sharply.

According to scientists from Lanzhou University, Gansu Province, China, the consumption of fossil fuels, the breathing process of humans, livestock and the number of fires is increasing rapidly has become The largest agent causes a sharp drop in oxygen levels in the air.

It is estimated that fossil fuel consumption accounts for 60-80% of the total oxygen consumption in the last century.

Oxygen is an indispensable oxygen to maintain life on Earth.

As we know, human and animal respiration continually consumes large amounts of oxygen and emits carbon dioxide in the atmosphere. In addition, the process of burning fossil fuels and generating energy also requires oxygen to maintain combustion. Therefore, it is not too much to say that oxygen is an indispensable oxygen to maintain life on Earth.

Scientists estimate that the world's oxygen concentration will decrease from the current level of 20.946% to only 20.825% if the annual oxygen consumption in the atmosphere increases to 100 billion tons by 2100.

Huang Jianping, the leader of the research team, urged heads of countries, environmental activists and all global citizens to take more drastic measures to combat the decline of oxygen .

This reduction in oxygen is not a major threat to human health.

According to Huang, although this reduction in oxygen is not a major threat to human health at the present time, if this trend continues, the environment will inevitably change. We cannot anticipate.

Huang stressed: " We must work harder to increase oxygen production and reduce consumption, such as promoting renewable energy use. However, the most critical condition to reverse this trend is. is a close cooperation between countries ".

The research by Chinese scientists was published in the recent Science Bulletin.
