I. Food: (1) April 22nd, Earth Day, a vegetarian day. Animal husbandry consumes a lot of grains and beans, as well as a lot of precious water; In order to herd cattle and raise pigs, the virgin forest was sacrificed, resulting in the greenhouse effect. (2) Eat less (cook at home, eat out in moderation, and pack up and go home after eating). (3) Fasting for one day (experience the taste of environmental protection in the body). (4) Refuse to use styrofoam, and ask cafeterias or coffee shops to use paper cups (styrofoam is a carcinogen and also destroys the ozone layer that protects the earth. Styrofoam cups and buffet plates for drinking coffee are still rubbish after hundreds of years and continue to pollute the environment. (5) Refuse to buy alpine tea and high-cold vegetables (alpine tea and high-cold vegetables make forests disappear in Taiwan Province Province, destroy soil and water conservation in mountainous areas, fail to play the role of water storage, and pollute water sources and reservoir ecology by using a large number of pesticides and fertilizers). ; Second, clothing: (1) Know the source of clothing materials: 1. Only natural materials such as natural cotton and hemp (organic) can be recycled. 2. Buy and maintain clothes according to the washing label to prolong the life of clothes. The demand is determined by four factors: the amount of laundry, the capacity of the family, lifestyle and economic situation. Try to control it well and don't overdo it. ⑶ Tips for wearing old clothes: ① Self-awareness: consideration of posture, skin color and lifestyle. (2) Find out the key points of fashion, such as length and color. Generally, simple and good cutting (three-dimensional cutting) can best express the interactive relationship between people and materials. (3) Accessories, such as scarves, pins, belts, etc., are small, diverse, effective and easy to collect, and a small amount of clothes are reliable accessories that highlight the artistic effect of dressing. (3) Housing: (1) More use of second-hand furniture (whether buying a house or renting a house, more use of second-hand furniture can not only be recycled, but also save resources. If flea markets for regular exchange of second-hand goods can be held in offices, communities and networks, (2) Use planting and greening for home decoration (don't do excessive decoration at home, take simplicity and nature as the principle. You don't have to use artificial materials for home layout. You might as well use more ecological natural materials. Potted plants of all kinds of flowers and plants, try to use native tree species, leave more natural soil in the courtyard at home, and use less cement or hard pavement). (3) Please use utensils to hold water, wash fruits and vegetables, wash dishes, brush your teeth and wash your face, so as to save precious water resources (China is the world's 18 water-deficient country, and South Taiwan Province Province has fallen into severe drought at present, but our current water demand has reached the standard of 100. At present, the propaganda policy of water saving in France is to take a bath once a week. If our water consumption continues to deteriorate, we will face the same situation. (4) Centralized use of power supply and air conditioning in rooms (one air conditioner should be opened as little as possible in a room, and the office should be concentrated as much as possible when there are few people, so as to reduce the amount of air conditioners and electric lights). 4. OK: (1) Take the stairs instead of the elevator (people who live in the building, whether in the office or at home, might as well walk instead of taking the elevator if they are not in a hurry, so it will save effort and exercise). (2) Go out and walk more, ride bicycles, use public transportation systems, drive less and ride motorcycles. 5. Others: (1) If you have a pet, please refuse to buy a cat and dog insect trap. When you throw away the cat and dog pest control ring, its pesticide composition is very destructive to the earth and will cause serious harm to the animal's body. (2) Refusing to buy products that use animals for experiments. A large number of cruel and unnecessary animal experimental projects not only waste taxpayers' taxes and cause natural genetic problems, but also do little to help and improve the ecological environment and major health problems. (3) Refuse to ride or use balloons (balloons are difficult to decompose chemicals and cause serious pollution to the earth. In addition, when the balloon floats away, it may lead to the death of wild animals (eagles, whales or turtles, etc.). ) wrong. )

Top ten environmental problems in the world

At present, the top ten environmental problems threatening human survival are: (1) Global warming. Due to the increase of population and the continuous expansion 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 The air quality is affected and the climate is getting warmer. Due to global warming, it will have various effects on the world. Higher temperatures can melt polar glaciers, and the sea level will rise by 6 cm every 10 year, which will flood some coastal areas. Global warming may also affect the changes of rainfall and atmospheric circulation, making the climate abnormal and prone to droughts and floods, which may lead to changes and destruction of ecosystems. Global climate change will have a series of significant impacts on human life. (2) The depletion and destruction of the ozone layer concentrates 90% of the ozone gas on the earth in the stratosphere 10~50 kilometers away from the earth's surface, and the ozone concentration is the highest at 25 kilometers away from the ground, forming an ozone concentration layer with a thickness of about 3 mm, which is called the ozone layer. It can absorb ultraviolet rays from the sun to protect life on earth from excessive ultraviolet rays, and store energy in the upper atmosphere to adjust the climate. However, the ozone layer is a very fragile atmosphere. If some ozone-destroying gases enter, they will react with ozone and the ozone layer will be destroyed. The destruction of ozone layer will increase the intensity of ultraviolet radiation on the ground and bring great harm to life on earth. Studies have shown that ultraviolet rays can destroy biological protein and genetic material deoxyribonucleic acid, leading to cell death; Increase the incidence of human skin cancer; Injury to the eyes, leading to cataracts and blindness; Inhibit the growth of soybeans, melons, vegetables and other plants. , and penetrate the water layer at the depth of 10 meter, killing plankton and microorganisms, thus endangering the food chain of aquatic organisms and the source of free oxygen, affecting the ecological balance and the self-purification ability of water bodies. (3) Reduction of biodiversity The Convention on Biological Diversity points out that biodiversity "refers to all kinds of organisms from all sources, including terrestrial, marine and other aquatic ecosystems and their ecological complexes; It includes diversity within species, between species and between ecosystems. " In the long process of biological evolution, some new species will be produced, and some species will disappear with the change of ecological environment conditions. Therefore, biodiversity is constantly changing. In the past century, due to the rapid increase of population, unreasonable exploitation of resources and environmental pollution, all kinds of creatures and their ecosystems on the earth have been greatly impacted and biodiversity has been greatly destroyed. Some scholars estimate that at least 50,000 biological species are extinct in the world every year, and an average of 140 species are extinct every day. It is estimated that by the beginning of the 265,438+0 century, the global wildlife loss will reach 65,438+05% ~ 30% of the total. In China, due to the pressure of population growth and economic development, the unreasonable utilization and destruction of biological resources, the loss of biodiversity is also very serious, and about 200 species have become extinct; It is estimated that about 5,000 species of plants are on the verge of extinction in recent years, accounting for about 20% of the total number of higher plants in China. About 398 species of vertebrates are also endangered, accounting for 7.7% of the total number of vertebrates in China. Therefore, it is also an important task for us to protect and save biodiversity and the living conditions on which these creatures depend. (4) acid rain diffusion acid rain refers to rain, snow or other forms of precipitation with PH below 5.6 in atmospheric precipitation. This is a manifestation of air pollution. The influence of acid rain on human environment is various. Acid rain falling into rivers and lakes will hinder the growth of fish and shrimp in water, leading to the reduction or extinction of fish and shrimp; Acid rain also causes soil acidification, destroys soil nutrition, makes soil barren, damages plant growth, reduces crop yield and damages forest growth. In addition, acid rain will corrode building materials. Relevant data show that in recent ten years, some historical sites in acid rain areas, especially stone carvings, stone carvings or bronze statues, have been destroyed for more than a hundred years, or even more than a thousand years. There are three major acid rain areas in the world. The acid rain area in South China is the only one that has not been treated. (5) Forests are drastically reduced on today's earth, and our green barrier, forests, is disappearing at an average rate of 4,000 square kilometers per year. The reduction of forest destroys its function of water conservation, leading to species reduction, soil erosion and reduction of carbon dioxide absorption, which further intensifies the greenhouse effect. (VI) Land Desertification The global land area accounts for 60%, of which desert and desertification account for 29%. Every year, 6 million hectares of land become desert. The annual economic loss is $42.3 billion. There are 5 billion hectares of arid and semi-arid land in the world, of which 3.3 billion hectares are threatened by desertification. As a result, 6 million hectares of farmland and 9 million hectares of pastoral areas lose productivity every year. The valleys of Tigris and Euphrates rivers, the cradles of human civilization, have changed from fertile soil to desert. Soil erosion in the Yellow River Basin of China is also very serious. (VII) 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. (8) Water pollution Water is what we need most in our daily life, and it is also one of the most exposed substances in the world. However, now even water has become a dangerous thing. (9) Marine pollution and human activities have increased nitrogen and phosphorus in coastal areas by 50%-200%; Excessive nutrients lead to a large number of coastal algae growth; Red tides occur in the Baltic Sea, the North Sea, the Black Sea and the East China Sea. Marine pollution leads to frequent red tides, destroying mangroves, coral reefs and seaweeds, resulting in a sharp decline in fish and shrimp in the offshore area and heavy losses in fisheries. (10) Transboundary Movement of Hazardous Wastes Hazardous wastes refer to wastes with chemical activity or toxicity, explosiveness, corrosiveness and other characteristics harmful to human living environment, except radioactive wastes. The United States stipulates in the Law of Resource Protection and Recovery that the so-called hazardous waste refers to a mixture of solid waste and several solids, which may cause or lead to human death or serious incurable diseases or disabilities because of its high quantity and concentration. What can we do on Earth Day 20 10? The Antarctic melted; Mother river is crying; The drought in Yunnan-Guizhou Plateau is serious; The forest is slowly disappearing; Some animals will be our memories ... 20 10 Earth Day, what can we do? At 20 10 on March 27th, we turned off the lights for one hour. We still need to stick to it: throw less garbage; Use less water; Use less sanitary chopsticks; Drive less ... Let's take care of our home, the earth!
