Humans also have "physical examination reports" on earth.

See but not see

Is anyone in charge?

Recently, the United Nations Environment Programme (UNEP) released the Earth Physical Examination Report-Living in Peace with Nature: A Scientific Blueprint for Dealing with Climate Change, Biodiversity Loss and Pollution Crisis (hereinafter referred to as the Report).

This report shows that:

Humans should completely change their views on the "physical health" of the earth.

This report on page 168 provides a "diagnostic analysis" for the current and predicted future changes of the earth's environment caused by human activities.

The report points out that in the process of pursuing wealth and security, we must immediately learn to cherish basic "natural capital" such as geology, soil, air and water.

Many people expressed their views on the newly released report. Ivar Bast of the Norwegian Environment Agency, one of the authors of the report, said: "We occupy three-quarters of the land and two-thirds of the ocean-we completely dominate the earth."

At the press conference to release the report, UN Secretary-General antonio guterres said: "For a long time, we have been waging a stupid and suicidal war against nature ... The result is three interrelated environmental crises: climate destruction, biodiversity loss and pollution, which threaten our own viability."

"We are destroying the earth and putting our own health and prosperity at risk," said Inger Anonson, executive director of the United Nations Environment Programme, who released the report.

As people concerned have pointed out, the world is far from achieving the goal of protecting the earth. Although the whole world has promised to do its best to protect the natural environment, species are disappearing at an unprecedented rate and the ecosystem is gradually deteriorating.

For example, the report shows that at the current rate, the global average temperature will rise by 65438 0.5℃ around 2040 or even earlier.

Although the ozone layer is slowly recovering, mankind has deviated from the track of improving global warming envisaged in the Paris Agreement.

In fact, in addition to the frequent extreme climate in recent years, human beings have paid other painful prices. At present, a quarter of the world's diseases are related to the environment-including diseases caused by wildlife foci or diseases caused by contact with toxic wastes discarded by human beings. Pollution causes about 9 million premature deaths every year.

But is it really completely irreversible? The report also pointed out that it is time to change this. The whole world is trying to recover from a subversive epidemic. While considering adopting major policies to restart the economy, governments of all countries can also seize this unique historical moment and give priority to protecting the earth.

"The COVID-19 epidemic crisis has prompted people to rethink how to accelerate the transition to a sustainable future."

"Curing" the thorny situation of the earth does not mean lowering the living standard or stopping the pace of poverty alleviation. For example, the report points out that people can consider adopting some policies to achieve change. For example, a study commissioned by the British Treasury this month suggested replacing gross domestic product (GDP) as an economic indicator with an indicator reflecting the true value of nature.

According to the report, "the economic and financial system does not take into account the basic benefits that human beings get from nature, nor does it provide incentives for human beings to manage the natural environment wisely and maintain its value.

Traditional indicators such as gross domestic product exaggerate the progress, because these indicators fail to fully reflect the cost behind the degradation of environmental level or the reduction of "natural capital" represented by geology, soil, air and water ... If the value of natural environment is excluded, investment will run counter to economic solutions to protect the environment, reduce pollution, expand renewable energy and use resources more sustainably. "

Guterres also exemplified how important it is to change economic thinking at this time. He pointed out, "when we see the GDP growth during overfishing, we think it is accumulating wealth, but in fact we are destroying nature ... we are also cutting down forests and destroying nature."

Therefore, if humans begin to consider the value of the environment and the cost of environmental degradation to our health and safety, then people's decisions may be different.

Robert, head of the United Nations scientific assessment of climate and biodiversity and another main author of the report? Professor Watson believes that this means challenging enterprises and countries with vested interests in the field of fossil fuels-the government must have the courage to take action; Financial institutions can play a great role in stopping providing funds for large-scale agriculture of fossil fuels, deforestation enterprises and single crop cultivation; Aggressive enterprises will realize that if they can continue to develop, they can become pioneers in the industry and make profits.

For another example, the report "Better Growth: Ten Key Changes in the Use of Grain Land" released by the Grain Land Use Alliance 20 19 shows that only 1% of the annual subsidies to farmers are used to improve the environment, and most of the remaining money accelerates the greenhouse gas emissions of livestock, forest destruction and pollution caused by excessive use of chemical fertilizers.

Therefore, trillions of dollars of subsidies provided to fossil fuels and "destructive" agriculture must be transferred to green energy and food production. In addition to systematic changes, people in rich countries can also take actions to reduce meat consumption and avoid wasting energy and water.

At the same time, taxing carbon emissions also needs to be put on the agenda.

Improving the earth's ecological environment is not only the responsibility of a country or institution, but also the joint efforts of all people on the earth.

Several global meetings planned this year are also expected to be opportunities to change the status quo-the United Nations Environment Conference will be held online next week, followed by the 15 Conference of the Parties to the Convention on Biological Diversity (COP 15) and the United Nations Climate Change Conference.

However, in Watson's view, it is better to start than to sit and talk.

People are far from reaching the biodiversity target set by 20 10. This year's summit should not only focus on goals, but also focus on actions.

Last year, China announced that it would strive to achieve the peak of carbon dioxide emissions in 2030 and achieve carbon neutrality in 2060. On February 1 this year, the Measures for the Administration of Carbon Emissions Trading (Trial) promulgated by the Ministry of Ecology and Environment of China was officially implemented.

On 19, local time in the United States, the United States officially rejoined the Paris Agreement to deal with global climate change. US Secretary of State Blinken said, "Now, just as we joined the agreement in 20 16, it is equally important for us to rejoin the agreement today, and what we do in the next few weeks, months and years is even more important."

Although there is still a long way to go to change the ecological status quo, it is important for people of all countries to take action and realize the goal of sustainable development step by step.

As Guterres said: "There is no precedent for what we are going to do, but if 2020 is a disaster, let 202 1 become a place where human beings begin to live in peace with nature to ensure a fair and sustainable future."

The UN Secretary-General warned that a new UN report urged us to completely change our view of nature, and the Guardian reported that human destruction of nature was "stupid and suicidal".
