1, pride in saving water-turn off the tap at any time to stop the water flow?
China is one of 12 water-deficient countries in the world, and its fresh water resources are less than14 of the world's per capita water. More than half of the more than 600 cities in China are short of water, of which 108 cities are seriously short of water. Groundwater resources are almost exhausted.
2. Protect the water source-protecting the water source means protecting life?
More than half of China's seven major water systems are polluted. Of the 35 key lakes, 17 are seriously polluted, and13 of the water bodies in China are not suitable for irrigation. More than 90% of urban waters are seriously polluted, more than 50% of urban water sources do not meet drinking water standards, and 40% of water sources are no longer drinkable.
3. Use one water for multiple purposes-let the water be reused?
70% of the earth's surface is covered with water, which is about 65.438+0.4 billion cubic meters, of which 96.5% is seawater. Although the rest is fresh water, more than half of it is water resources that can be directly used, such as ice, rivers and lakes, accounting for only about 0.003% of the total water.
4, turn off the lights-save electricity, less pollution?
China is a country with thermal power generation as the main energy source and coal as the main energy source. Coal accounts for more than 70% of the disposable energy structure. If it develops in the conventional way, it will need at least 654.38+000 billion tons of coal for energy consumption to reach the level of developed countries, which will be equivalent to the sum of global energy consumption. When coal burns, it will release a lot of harmful gases, seriously pollute the atmosphere, form acid rain and cause greenhouse effect.
5. Save electrical appliances-what to do to slow down global warming?
A large number of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation. The excessive carbon dioxide produced by burning these fuels is like a glass cover, which blocks the radiation of ground heat to outer space and leaves hot gas in the atmosphere, forming a "greenhouse effect". If the warming trend continues, the low-lying deltas in Bengal, Holland, Egypt and China and some island countries will be in danger of being swallowed up by the sea.
6. Support green lighting-everyone uses energy-saving lamps?
"China Green Lighting Project" is one of the key points of energy saving in China. According to the implementation plan of the project, energy-saving and high-efficiency lighting lamps will be promoted throughout the country during the Ninth Five-Year Plan period. By the year 2000, we will strive to save 22 billion kWh of lighting electricity, save the corresponding coal burning in power plants, and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide.
7. Use renewable resources-don't wait until the energy runs out?
90% of the energy currently used by mankind is oil, natural gas and coal. The formation of these fuels takes hundreds of millions of years, and they are non-renewable resources. Solar energy, wind energy, tidal energy and geothermal energy are renewable and are called renewable energy. People call those energy sources that do not pollute the environment "clean energy".
8. Being a "riding hero"-protecting the atmosphere starts from one step?
In Europe, in order to reduce air pollution caused by driving, many people are willing to go to work by bike. Such people are respected as environmental defenders. In order to purify the urban air, the Iranian capital Tehran has set up a "selfless car-free day". On this day, the Iranian president also went to work by bus with the citizens. In China and Shanghai, employees of some companies often share a taxi, which is called "fighting".

1, International Wetlands Day
Wetlands refer to "swamps, peatlands or waters that are static or flowing for a long time or temporarily, or water bodies of fresh water, brackish water or salt water, including waters less than 6 meters at low tide". Wetlands play an important role in protecting biodiversity, especially the survival and migration of birds.
2. World Water Day
Starting from 1994, the China Municipal Government changed the time of "China Water Week" to March 22nd-28th every year, which made the publicity activities more prominent on the theme of "World Water Day".
3. World Meteorological Day
1960, the World Meteorological Organization designated March 23rd as "World Meteorological Day" to arouse public attention to meteorological issues.
