1On June 5th, 972, the United Nations held the first conference on the human environment in Stockholm, Sweden, and adopted the famous Declaration on the Human Environment and the Action Plan for Protecting the Global Environment, putting forward the slogan of "protecting and improving the environment for this generation and future generations". This is the first conference in human history to study and protect the human environment in the world.
11300 delegates from13 countries and regions suggested that the opening day of the conference be "World Environment Day".
The delegation of China actively participated in the drafting of the above declaration, and put forward the 32-word policy of the China government on environmental protection approved by Premier Zhou Enlai at the meeting: "Overall planning, rational layout, comprehensive utilization, turning harm into benefit, relying on the masses, jointly protecting the environment and benefiting the people."
In the same year, the 27th General Assembly of the United Nations decided to establish the United Nations Environment Programme (UNEP) on the basis of the recommendations of the Stockholm Conference, and designated June 5th as World Environment Day every year, requiring United Nations agencies and governments and organizations around the world to hold various activities to protect the environment and combat public hazards around June 5th every year. The United Nations Environment Programme also publishes the annual report on the state of the world environment on this day.

Environmental problems that threaten human survival;
1, global warming
With the increase of population and the continuous expansion of the scale of human production activities, greenhouse gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), carbon tetrachloride (CCl4) and carbon monoxide (CO) are released into the atmosphere, resulting in changes in atmospheric composition.
2, the loss and destruction of the ozone layer
The ozone layer can absorb ultraviolet rays from the sun to protect life on earth from excessive ultraviolet rays, and store energy in the upper atmosphere to regulate the climate. However, the ozone layer is a very fragile atmosphere. If some ozone-destroying gas enters, it will react with ozone, and the depletion layer of the ozone layer will be destroyed.
3. Air pollution
The main factors of air pollution are suspended particles, carbon monoxide, ozone, carbon dioxide, nitrogen oxides and lead. Air pollution causes 300,000-700,000 people to die prematurely every year due to smog pollution, 25 million children suffer from chronic laryngitis, and 4-7 million rural women and children get sick.
