Nearly 60% of terrestrial species diversity has been severely damaged

China News Service, July 16th, according to foreign media reports, a research report in the latest "Science" journal stated that the completeness index of species diversity in 58% of the earth's land area has fallen below the safe value

The report pointed out that the grasslands of the United States, Argentina, South Africa and Central Asia are the most affected by this, and the number of animals and plants in these areas has been reduced due to human activities

The main author of the report is Newbold, a scholar at University College London.

After the level of species diversity is reduced, natural ecological service systems such as crops that rely on bees and other insects to pollinate and spread, healthy soils that produce nutrients and water for food crops, and forests that absorb carbon dioxide in the atmosphere to cope with climate warming will face greater challenges.

Purvis, another author of the report, said, “Many policymakers are most worried about economic recession, but they don’t know that ecosystem recession is likely to bring more serious consequences
