1. Food: (1) Eat vegetarian food for one day on Earth Day, April 22nd. (Animal husbandry consumes a large amount of grains and beans, as well as a large amount of precious water; in order to graze cattle and raise pigs, virgin forests are sacrificed, causing a greenhouse effect). (2) Eat less (cook at home and eat out in just the right portion, and take it home if you can’t finish it). (3) Fast for one day (to experience the taste of environmental protection in the body). (4) Refuse to use styrofoam and require buffets or coffee shops to use paper cups (styrofoam is a carcinogen that also destroys the ozone layer that protects the earth. Styrofoam cups and buffet plates for drinking coffee have been around for hundreds of years It will still be garbage and continue to pollute the environment). (5) Refuse to buy high-mountain tea and high-cold vegetables (high-mountain tea and high-cold vegetables have caused Taiwan’s forests to disappear, destroyed mountainous soil and water conservation, and cannot function to store water. They also use large amounts of pesticides and fertilizers, polluting the ecology of water sources and reservoirs) . ; 2. Clothing: ⑴ Understand the source of clothing materials: 1. Choose natural cotton, linen and other natural materials (organic) before they can be recycled. 2. Buy and maintain clothes according to the washing instructions to extend the life of the clothes. ⑵Determining the demand depends on four factors: the frequency of laundry, the capacity of the home, lifestyle, and economic conditions to determine the frequency of clothing purchase. Try to control it well and not exceed the quantity (focusing on quality rather than quantity). ⑶ Tips for re-wearing old clothes: ① Self-awareness: Consideration of body shape, skin color, and lifestyle. ② Find out the popular key points: such as length, color, etc. Generally, simple and good tailoring (three-dimensional tailoring) can best express the interactive relationship between people and materials. ③Accessories, such as scarves, pins, and belts, are small in size, can be varied, have good effects, and are easy to collect. A small amount of clothes can be used as reliable accessories to highlight the art of dressing. 3. Living: ⑴Use more second-hand furniture (whether buying a house or renting a house, use more second-hand furniture, which can be recycled and reused and save resources. If you can hold regular second-hand flea markets in offices, communities, or online, it is environmentally friendly. , and can help each other and enhance interpersonal friendship). ⑵Use more planting and greening for home decoration (do not do excessive decoration at home, the principle should be simple and natural. Home decoration does not have to be artificial materials, you may as well use more ecological natural materials. A variety of potted flowers and plants, try to Use native tree species. If your home has a courtyard, leave more natural soil and less cement or hard pavement.) ⑶ Please use utensils to hold water, wash fruits and vegetables, dishes, brush teeth, and wash your face to save precious water resources (China is the 18th water-scarce country in the world. Currently, southern Taiwan has fallen into a severe drought, but our current water use The demand has reached the standard of the 100th year of the Republic of China. France's current water conservation policy is "take a bath once a week"; if our water consumption continues to worsen, we will also face the same situation (4) Power supply and air conditioning in the room. Concentrate use (try to use one air conditioner in one room as little as possible, work together when there are few people, and reduce the use of air conditioners and lights). 4. Do: ⑴ Take the stairs, do not take the elevator (those who live in the building, whether in the office or at home, If you are not in a hurry, you might as well try walking instead of taking the elevator, and take the stairs instead, which not only saves energy, but also allows you to exercise) ⑵ Walk more, ride a bicycle, use the public transportation system, and drive less and ride a motorcycle. 5. Others: ⑴ If you keep pets, please refuse to buy cat and dog insect repellents (when you discard cat and dog insect repellents, the pesticide ingredients are very lethal to the earth and can cause serious harm to the animal's body. harm). ⑵Refuse to purchase products tested on animals (A large number of cruel and unnecessary animal testing programs not only waste taxpayers’ tax dollars and cause problems in natural genetic inheritance, but also do not cause many major health problems for the ecological environment. (3) Refuse to take or use balloons (balloons are very difficult to decompose chemicals, which cause serious pollution on the earth. In addition, when the balloons float away, they may cause damage to wild animals (eagles, whales or Sea turtles, etc.) die from accidental ingestion)

Top Ten Environmental Problems in the World

Currently, the top ten environmental problems that threaten human survival are: (1) Global warming due to With the increase in population and the scale of human production activities, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFC), and carbon tetrachloride (CCl4) are released into the atmosphere. ), carbon monoxide (CO) and other greenhouse gases are increasing, causing changes in the composition of the atmosphere. The air quality is affected, and the climate is gradually warming. Due to global warming, it will have various impacts on the world. High temperatures can cause polar glaciers to melt and sea levels to rise by 6 centimeters every 10 years, thus causing some coastal areas to be submerged. Global warming may also affect changes in rainfall and atmospheric circulation, making the climate abnormal and prone to drought. Waterlogging disasters, all of which may lead to changes and destruction of ecosystems, and global climate change will have a series of major impacts on human life. (2) The depletion and destruction of the ozone layer is concentrated in the stratosphere 10 to 50 kilometers above the earth's surface. It has absorbed 90% of the ozone gas on the earth. The ozone concentration is maximum at 25 kilometers above the ground, forming an ozone concentration layer with a thickness of about 3 mm, called the ozone layer.

It absorbs ultraviolet rays from the sun to protect life on earth from excessive ultraviolet rays, and stores energy in the upper atmosphere to regulate the climate. But the ozone layer is a very fragile atmosphere. If some gases that destroy ozone enter, they will react chemically with ozone, and the ozone layer will be destroyed. The destruction of the ozone layer will increase the intensity of ultraviolet radiation on the ground, causing great harm to life on earth. Research shows that ultraviolet radiation can destroy biological proteins and genetic material DNA, causing cell death; increasing the incidence of skin cancer in humans; damaging the eyes, causing cataracts and blindness; and inhibiting the growth of plants such as soybeans, melons, vegetables, etc. , and penetrates the water layer 10 meters deep, killing plankton and microorganisms, thereby endangering the food chain of aquatic organisms and the source of free oxygen, affecting the ecological balance and the self-purification ability of the water body. (3) Reduction of biological diversity. The Convention on Biological Diversity states that biological diversity “refers to the wide variety of living organisms from all sources, including terrestrial, marine and other aquatic ecosystems and the ecological complexes they constitute; it Including diversity within species, between species, and in ecosystems. “In the long process of biological evolution, some new species will be produced, and at the same time, as ecological environmental conditions change, some species will also disappear. Therefore, biological diversity is constantly changing. In the past century, due to the rapid increase in population, irrational exploitation of resources by humans, and environmental pollution, various organisms and their ecosystems on the earth have been greatly impacted, and biodiversity has also been greatly affected. damage. Relevant scholars estimate that at least 50,000 biological species become extinct in the world every year, with an average of 140 species extinct every day. It is estimated that by the beginning of the 21st century, the loss of wildlife worldwide will reach 15% to 30% of the total number. In China, due to the pressure of population growth and economic development, the irrational use and destruction of biological resources, the loss of biological diversity has also been very serious. About 200 species have become extinct; it is estimated that about 5,000 plant species have become extinct in recent years. are already in an endangered state, accounting for about 20% of the total number of higher plants in China; about 398 species of vertebrates are also endangered, accounting for about 7.7% of the total number of vertebrates in China. Therefore, protecting and saving biological diversity and the living conditions on which these organisms depend are also important tasks before us. (4) Spread of acid rain Acid rain refers to rain, snow or other forms of precipitation with a pH value below 5.6 in atmospheric precipitation. This is a manifestation of air pollution. Acid rain has many impacts on the human environment. When acid rain falls into rivers and lakes, it will hinder the growth of fish and shrimp in the water, causing the fish and shrimp to decrease or disappear; acid rain also causes soil acidification, destroys soil nutrients, makes the soil barren, harms the growth of plants, causes crop yield reduction, and harms Forest growth. In addition, acid rain also corrodes building materials. Relevant data show that in the past decade or so, some monuments in acid rain areas, especially stone carvings, stone sculptures or copper statues, have been damaged more than in the past for more than a century or even a thousand years. There are currently three major acid rain areas in the world. The acid rain area in South my country is the only one that has not yet been controlled. (5) Sharp decline in forests On today’s earth, forests, our green barrier, are disappearing at an average rate of 4,000 square kilometers per year. The reduction of forests destroys their function of conserving water sources, resulting in the reduction of species and soil erosion, and reduces the absorption of carbon dioxide, which in turn intensifies the greenhouse effect. (6) Land desertification The global land area accounts for 60%, of which 29% is desert and desertification area. Six million hectares of land turn into desert every year. Economic losses are US$42.3 billion annually. There are 5 billion hectares of arid and semi-arid land in the world, 3.3 billion of which are threatened by desertification. As a result, 6 million hectares of farmland and 9 million hectares of pastoral areas lose productivity every year. The Tigris and Euphrates river basins, the cradle of human civilization, have turned from fertile soil into desert. China's Yellow River Basin also suffers from serious soil erosion. (7) Air pollution The main factors of air pollution are suspended particulate matter, carbon monoxide, ozone, carbon dioxide, nitrogen oxides, lead, etc. Air pollution causes 300,000 to 700,000 premature deaths every year due to smoke and dust pollution, 25 million children suffer from chronic laryngitis, and 4 to 7 million rural women and children are affected. (8) Water pollution Water is one of the substances we need most in our daily life and are most exposed to in the world. However, even water has now become a dangerous product. (9) Marine pollution Human activities have increased nitrogen and phosphorus in coastal areas by 50%-200%; excess nutrients have caused massive growth of coastal algae; red tides have appeared in the Baltic Sea, North Sea, Black Sea, East China Sea (East China Sea), etc. Marine pollution causes frequent red tides, destroying mangroves, coral reefs, and seagrasses, causing a sharp decline in offshore fish and shrimp, and causing heavy losses to the fishery industry. (10) Transboundary Movement of Hazardous Wastes Hazardous wastes refer to wastes other than radioactive wastes that are chemically active or toxic, explosive, corrosive and have other harmful properties to the human living environment. The United States stipulates in the Resource Conservation and Recovery Act that the so-called hazardous waste refers to a solid waste and a mixture of several solids. Because of its high quantity and concentration, it may cause or cause human death, or cause serious and difficult-to-treat diseases or cause serious illness. Remaining waste.

What can we do on Earth Day 2010? The Antarctic ice is melting; the mother river is crying; the Yunnan-Guizhou Plateau is suffering from severe drought; the forests are slowly disappearing; some animals will become our memories... What can we do on Earth Day 2010? Let us turn off the lights for one hour on March 27, 2010; we still need to continue to do: Throw less garbage; Use less water; Use less sanitary chopsticks; Drive less cars... Let us take care of us together Our common home - Earth!
