1, environmental protection is an eternal topic, and it is a problem that human beings must pay attention to in sustainable development. Environmental protection of the earth needs everyone's efforts, and marine health also needs our protection. A lot of rubbish and some harmful substances were thrown into the ocean. People throw rubbish into such a big ocean. Now the ocean has become the largest garbage dump, where all kinds of garbage from all over the world gather.
2. Polluting water resources means that nuclear explosion kills human beings. What human beings do is to harm themselves in the end. At first, the pollution discharged into the river exceeds the self-purification ability of the river, and finally it will become poison and eat into human mouth. A simple picture element plus an easy-to-understand copy constitutes a frightening environmental poster design.
3. The design of this environmental poster gives people the first impression. Under the lush green hills, there is turbid black harmful liquid flowing out of an artificial iron bucket, which is constantly disturbing people. The design of environmental protection poster is to use the displacement to turn the river into industrial liquid, and put a large industrial bucket at the source of the river. The picture is so expressive that it doesn't need a copy to explain it.
Provide information:
1, saving water is pride ―― turn off the tap at any time and don't let the water run empty. 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 more than 600 cities in China are short of water, among which 108 cities are seriously short of surface water resources, resulting in over-exploitation of groundwater. In the 1950s, wells in Beijing were able to pump water from 5 meters underground. Now the average depth of 40,000 wells in Beijing is 49 meters, and the groundwater resources are almost exhausted.
2. Protect the water source-protecting the water source means protecting life. According to environmental monitoring, about 6,543.8 billion tons of sewage is directly discharged into water bodies every day in China. 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, 40% of water sources are no longer drinkable, and 60%-70% of the total water shortage in southern cities is caused by water pollution.
3. Multi-use of one water-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.
