The Earth reaches the threshold of 'danger' to human survival

The Earth is gradually becoming dangerous to human survival, while people and their activities have contributed greatly to this situation. This is the result of a study published in the journal Science on January 15.

A group of 19 international experts conducted a 9-limit survey of Earth's safety assessment of human survival according to a report published in 2009.

Among 9 criteria, there are 4 criteria, including climate change, biodiversity, changes in land resource use and environmental pollution due to fertilizer abuse - both exceeded the safety threshold.

In particular, climate change and loss of biodiversity due to the number of extinct species exceeding the permitted threshold are two key criteria because if either of these two factors exceeds the serious limit for a long time, it may cause left Land falls into a completely new state.

Research results indicate alarming reality. While the amount of CO2 in the atmosphere at 350ppm is considered safe, it actually reached 397ppm, while the proportion of extinct species due to pollution or deforestation is higher than 10 to 100. Safety limit times allowed.

Other criteria such as the use of water resources, the level of acidity in the ocean environment and the degree of ozone depletion are still within safe limits.

Experts identify human beings themselves as making their living environment more harsh, destroying all efforts to reduce poverty and improve the quality of life.

The experts also warned about deforestation and environmental pollution caused by nitrogen and phosphorus in fertilizers.

This new study will be based on the United Nations as the Millennium Development Goals to help humanity balance the need for economic development with the goal of environmental protection.
