About
Earth Day Earth is the mutual home, but as science and technology development and economic expansion of the scale of the global environment over the past 30 years, continued to disintegrate. Some data indicate that: Since 1860, meteorological detection equipment since records began, the global average temperature increases by 0.6 degrees Celsius, the 13 warmest years since 1983 were .20 in the 80's, the global number of people affected by disasters every year an average of 147 million, and 90 to the 20th century, This figure rose to 2.11 billion. About 40% of the world's population a serious water absence, if this trend is not inhibited, in 30 years, more than 55% of the global population will face water shortages. also a serious deterioration of the natural environment threatened wildlife species on the planet. Today nigh 12% of bird species and a quarter of mammals threatened with extinction, when one-third of over-fishing has led to depletion of fish resources.
1970 年 4 月 22 日in the Pacific Ocean to the United States, people in mandate to solve environmental pollution problems, spontaneously set off a massive hunk environmental movement. On this day, the nation's 10,000 state schools, 2,000 colleges and universities and 2000 community and major groups totaling more than 2,000 people took to the avenues. It held up the contaminated earth model, giant paintings, graphics, shouting slogans to protect the environment, at ***, assembly and lecture, cried on the Government to take measures to protect environment. The grand event, shocked the ruling and against, provocation the U.S. government in the early 70s by the Water Pollution Control Act and the Clean Air Act corrections and the establishment of the United States Environmental Protection Agency. Since then, the U.S. non-governmental organizations proposed to April 22 day as in environmental protection worldwide has made great progress in .1972 in June, the United Nations convened a landmark meeting of the Human Environment, 1973, created the United Nations Environment Programme, many countries have built the Environmental Protection management agencies and research traditions, environmental protection was put on a lot of the citizen government agenda, the environment has been widespread public concern. in many major international conference on environmental protection has become one of momentous issues, such as the 1989 appointment 44 conference of the General Assembly, the Non-Aligned Summit, the Commonwealth summit meeting of 7 western countries summit to discuss environmental issues and so on, and accepted resolutions or assertions on environmental protection. This shows that environmental protection has become an international political and international relations protection has become a focus of international politics in 1990, Earth Day organizers decided to make Earth Day in 1990 became the first international Earth Day, to make hundreds of millions of people are to actively participate in environmental protection. To Therefore, the organizers of Earth Day activities sent a letter to China, the United States, Britain and the United Nations Secretary-General of the leaders, cried for April 22, 1990 as the target date, held senior environmental meetings lay the foundation for the conclusion of multilateral treaties. calls upon States to take assured treads to reach an accord to halt and reverse the development trend of global environmental degradation. also called on the world is compliant to protect the environment, international cooperation, the Government, held in their to movements to improve the environment. As Earth Day 1990 to mark International Earth Day. Asia, Africa, the Americas, many countries and zones have reacted positively to organize commemorative activities. many international organizations, such as the International Union of Students, Youth Development and Cooperation Association, also have expressed their strong support and active participation in hundreds of millions of people. Since then, the development and coordinated development of environmental protection. China 90 years from the 20th century, the annual April 22 Earth Day events are held.
the origin of Earth Day:
human history, the first ;, is April 22, 1970, by a Harvard Law School student who just turned 25-year-old Dennis mm. Hayes initiated and organizations on university. him today as the ;. But in fact, Nelson, trying to argue President Kennedy to conduct a wildlife junket to rouse public attention to environmental protection, the President very much admit with the constructive suggestions. second year of the fall, Nelson and the other three senators, attended the President The Earth Day activities in commemoration of the citizen arrange and in the same year it was announced early in September, including major campus in the nation organized lectures and other environmental issues. the American people has been overwhelming, so Nelson has started feeding no time.
1969 年 Gallo. Nelson intended that the major environmental issues held in the educate garden lectures, Hayes heard the proposal to prop a vision of environmental protection in Cambridge in the speech. Thus, He went to Washington to encounter with the Nelson. Young Hayes speak about their vision, Nelson was overjoyed and quickly attempted rendezvous Hayes, and even encouraged him to temporarily stop their studies to concentrate in the environmental movement. As a result, Hayes judged procedures for the suspension. Before long, he brought the motif of ​​expanding Nielsen, escape from cross the United States fired a large-scale community-based activities. held He chose 22 日 1970 年 4 月 (Wednesday) the first
the United States in 1970 was a troubled, out of fiber cloth was contrived, , when the American luxury car always day breathing the lead fumes. plant with smoke with impunity and sewage dismiss, but never worried about being prosecuted or doomed by public opinion. listed in the lexicon of words, but few can be taken seriously. It is in this context, the first the importance of meeting people gathered in Washington, DC, .25, 10 million people to march on Fifth Avenue in New York City in support of this event.
According to statistics, this day more than 2,000 people extensive, 10,000 basic and secondary schools 2000 campuses and universities and 2,000 community and major groups in the and charts, shouted slogans urging the Government to take fathom to protect the environment .1970 with the first rise, and hinted the U.S. government has taken some measures to control environmental pollution.
1970 年 4 22 May, the beginning of the modern environmental campaign, which promoted the establishment of environmental regulations in Western countries. If the United States has issued a Clean Air Act, Clean Water Act and Endangered Species Protection Act and additional regulations; Earth Day in 1970 also contributed to the National Environmental Protection Agency establishment, and in a way, contributed to the 1972 United Nations Conference aboard Human Environment in Stockholm, the premier convening of a muscular momentum to the development of the globe In 1973 the Environmental Protection establishment of United Nations Environment Programme, one multinational environmental union Greenpeace mm creation, and protecting the environment of administration agencies and organizations in the globe continues to addition, br> In the 1st , the **, cultural performances and other activities to promote a wash environment, Shang said that the development groups in 140 countries with April 22, 1990) as activities by the climax of the week.
1990 年 4 22 this day, hundreds of millions of people around the world dressing a blue-green and white clothing to attend the mark defend the Earth's environment, contribute to improving the global environment. wearing a blue and green and white clothe is said to act to protect the decision of the global environment.
not at home to prevent the exhaust emitted from cars and other harmful emissions into the atmosphere to go. In China, when Premier Li Peng on April 21 issued a TV address environmental problems, China Central Television also announce ; only one earth, r l Earth Day on China Action ) attach for the Day Nelson and Dennis. Hayes leadership, the inconsistency is, this period in 1970 manner, the knowledge and enthusiasm of peoples gathered attach. in the Gallo. Nelson, Dennis. Hayes and the exertions of their comrades,toronto escorts, today's festival, a reminder of human protection of the Earth, to treat the Earth.
nature-loving identity from childhood. to the campus, though he read the decree, but has not given up on environmental concerns.
the first Department supervised by the adviser of Solar Energy Research Institute. Hayes has been engaged in environmental activities, in 1988, he systematized the debate with friends commemorate the 20th anniversary of Earth Day activities. His suggestion was speedily most of the world and the United Nations assist.
light of Dennis. Hayes in environmental protection in the important contribution made, he was awarded the Sierra Club, the Federal Wildlife Federation, the United States Humane Society, American Solar Energy Society, away from the campaign and the Interfaith Centerfor Corporate Organization Responsibility of the maximum medal gift. Dennis. Hayes also won the 1978 year, 35 years antique Jefferson Award for best social services, but also was the picture of magazines (Look Magazine) as the 20th century's 100 most influential Americans of the one, and was named the National Audubon Society 100 one of the most famous environmentalists. In 2000, Time journal has been prominent (Time Magazine) named 100 Earth Day Earth Day theme

What can you do?
memorize the picture of world-renowned lyricist Barbara. Cooney (Barbara Cooney ) is a art , hh, but these are good, you have to do one thing: make the world more pretty. So, the little girl grew up, choose a beautiful beach lined with blue, violet hyacinth bean flowers and beautify the earth.
one, April 22 Earth Day vegetarian daytime. (cattle waste great amounts of Valley, beans, and waste large amounts of precious water; for grazing livestock and pig, the disbursement of maiden forest, causing the greenhouse effect. < br> Second, eat (at home, cooking, eating just the right weight, take leftovers home)
3 day fasting (Experience the taste of green body)
four, refused to use styrofoam, and requested restaurant or coffee mart using paper glasses (styrofoam is a carcinogenic substance, it also damaged the ozone layer protecting the earth. styrofoam coffee cups, strike trays, a few hundred years, or nay to proceed to pollute the environment). < br> e, refused to buy high mountain tea, mountain vegetables (high mountain tea, mountain vegetables to Taiwan, deforestation, destruction of mountain soil and water conservation, can not play the function of storing water, and heavy use of pesticides and fertilizers, pollution of water and reservoir nature ).
clothing:
one, recognizing dressing Source: 1. buy natural cotton, hemp and other natural materials (organic in ecology), be recycled. 2. according to standard washing clothes to buy clothes and maintenance, to amplify the life of clothes.
Second, the determination of the demand, along to: the number of laundromat, home size, lifestyle, financial situation to decide the four factors of the frequency buy raiment, try to control is good, not excessive (massive not weight).
Third, new clothes to wear tips:
1. Self-awareness: body, skin color, lifestyle considerations.
2. to detect the renowned converge on: such as length, color , are generally simple, good tear (D mow) showed the maximum interaction between male and material.
3. Accessories for small size, changing, good effect, collecting easier, such for scarves, needles, belt , a small value of clothing that is reliable and clothing accessories apt highlight the effect of masterpiece.
live:
1, the use of second-hand furniture (if to purchase a house, rent an apartment, more use of second-hand furniture, recycling tin save resources, If in the bureau, the community, organizing regular second-hand thrift exchange web flea mart, the environment, yet also mutual help and promote friendship surrounded people).
Second, and extra to do at family with the tree planting arrangement (no to do at family transitional decor arrangements ought be uncomplicated, natural conviction. family layout does not necessarily man-made substance, may wish to use the ecological normal materials. a diversity of flowers and potted plants, try to use indigenous category, at home in the garden to stay normal resistance soil, use less cement, or hard of sidewalk).
Third, use receptacles fraught with water, washing fruits and vegetables, dishes, brush your teeth, rinse your face, to save precious water (China is the world's tenth ranked 8 water-scarce countries, the new severe drought in southern Taiwan have been caught, but we now claim the use of water has already reached the criterion of the Republic of China 100 years. France's current water conservation improvement policy is continued deterioration of our water, we will face the same location.
four rooms of the power afford, air-conditioning condense use (as tiny as likely to open an air-conditioned room, who came from a centralized office as many as likely, reduce air-conditioning, cordless usage) .
line:
one, take the stairs, not hoist (living in the erection, whether in the office or home, if you do not hurry, we might try to walk car, try not to take the elevator, the stairs instead of not only save energy, but also sports and fitness).
Second, work out to wade, bike, use public transmission, less driving and riding a motorcycle.
Other:
one, if you reserve pets, please refusing to buy dogs and cats bane control circulate (when you reject the cats and dogs bane control loop, the pesticide composition of the Earth's destruction is very strong, and the animal's body would cause serious harm).
Second, refuse to buy accustomed Animal experiment of productions (a lot of needless animal oppression procedure, in addition to a waste of taxpayer's taxes, resulting in natural genetic inheritance issues, the ecological environment of Taiwan is also a major health problem and there is not many help and correction.
Third, refusing to take or use the balloon (the balloon is very tough to wreck down the chemicals, which caused serious pollution on the planet, in increase, when the balloons drift away, may lead to wildlife (eagles, whales or sea turtles, etc.) misdeed the phenomenon of food and death).

world's top ten environmental problems currently threatening the top ten environmental problems of human subsistence is:
(a) global warming
increase in population and human production the increasing scale of activities, the release of carbon dioxide to the atmosphere (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFC), carbon tetrachloride (CCl4), carbon monoxide (CO) and other greenhouse gases continue to increase, leading to changes in the composition of the atmosphere. affected air quality, climate is gradually warming. because of global warming on the global generate different effects, higher temperature allows the polar thawing glaciers, sea level will rise by 6 cm in 10 years, which will grant some coastal areas were dipped. global warming may affect rainfall and airy rotation changes, so that unstable climate, could lightly lead to droughts and floods, which may lead to changes and destruction of ecosystems, global climate change will have a significant impact on human lives.
(b) of the ozone layer depletion and destruction
away from the surface of the Earth's air 10 to 50 km in the concentration of stratospheric 90% of the globe ozone gas in the ground 25 kilometers away from the highest ozone concentration, the formation of a thickness of about 3 mm floor of ozone concentration, understood as the ozone layer. it can preoccupy the sun's ultraviolet rays to protect life on Earth free UV harm was redundant, and the stamina cached in the upper atmosphere, play a character in regulating air. However, the ozone layer is a very brittle air, whether you enter the number of ozone-destroying gases, they will, and chemical effects of ozone, the ozone layer will broke. ozone layer is broke, the ground will increase the intensity of UV radiation at, life on the world to send excellent damage. studies have shown that UV radiation harm to biological proteins and genetic material DNA, causing cell necrosis; the increase in the occurrence of human skin sarcoma; harm eyes and reason blindness cataract leaving; tabooed plants such as soybeans, melons, vegetables and other growth, and see the water layer 10 m deep, slaying plankton and micro-organisms, thereby endangering aquatic edible fetter and a source of free oxygen, affecting the ecological poise and water self-purification capacity.
(c) loss of biodiversity
varieties of organisms, these sources contain terrestrial, marine and other aquatic ecosystems and the ecological complexes; It includes diversity within species, between species and ecosystem diversity. some new species, same time, with changes in environmental conditions, some species will also disappear. So, biodiversity is changing. over the past century, due to fast population growth and human resources are not rational development, coupled with environmental pollution and other reasons, the Earth's manifold biological and ecological systems has been a great impact on biodiversity has also been a lot of damage. For savants estimate that the world every year at fewest 50,000 kinds of biological species extinction, extinction of species per day up to 140, estimated that the early 21st century, the loss of wildlife around the world up to the total of 15% to 30%. In China, due to population growth and economic development of the pressure on the biological irrational use of resources and destruction, biodiversity losses suffered very serious, some more than 200 species have become extinct; estimated that about 5,000 kinds of plants have been endangered in recent years, the total number of higher plants in China which accounted for about 20%; there are still about 398 kinds of vertebrates are also at the endangered status, accounting for about 7.7% of the total number of vertebrates. Therefore, protect and save biological diversity and the survival of these organisms living conditions, the same is placed in the important missions before.
(d) Acid Rain Acid rain refers to the scatter of
precipitation pH (PH amount) of less than 5.6 rain, sleet or other fashions of precipitation. This is a declaration of air pollution. Acid rain impact on the human environment in numerous ways. rain fall into creeks, lakes, will prevent water fish, shrimp growth, resulting in reduction or extinction of fish and shrimp; mordant rain also led to soil acidification, havoc of soil nutrients to the soil barren of harm plant growth, resulting in harvest creation, endangering the forest's growth. In addition, mordant rain and also the corrosion of creating materials, relevant message that indicates the final ten-year, a number of areas of acid rain of special note, stone memorials, stone or bronze statues of the damage over the quondam hundred years more, even thousand years. At present, three important world acid rain. acid rain in south China is not the merely governance.
(e) dropped
forest on Earth today, we have a green screen - Forest 4000 square kilometers at an mean annual rate of evaporate. forests, water conservation feature to reduce its damage, resulting in the rebate of species and soil erosion, reducing the digestion of carbon dioxide in corner worse the greenhouse effect.
(f)
land desertification accounted for 60% of universal land zone, of which 29% space of ​​deserts and desertification. Every year 600 million hectares of land into desert. 423 million in economic losses each annual. international in arid and semi-arid land 50 million hectares, of which 3.3 billion was the menace of desertification. resulting in an annual 600 million hectares of farmland, 900 million hectares of pastoral lost productivity. the cradle of human culture, the Tigris, the Euphrates ravine,toronto escort, the fertile land into desert. China's Yellow River The Yellow River --- soil erosion is also very solemn.
(g) air pollution
main factor of climate pollution particulate stuff, carbon monoxide, ozone, carbon dioxide,Easter Monday, nitrogen oxides, lead. climate pollution led to 30-70 million people each year smoke and dust pollution deserving to early deaths, 25 million children suffering from continuing laryngitis, 400-700 million rural women and children suffer.
(h) water pollution
most of our everyday needs, but also the greatest exposure to substances First, whatsoever, the water is now also become precarious merchandise
(ix) navy pollution
human activities offshore area of ​​nitrogen and phosphorus by 50% -200%; excess nutrients cause algal growth onward the beach; the Baltic Sea, North Sea , the Black Sea, the East China Sea and other red tide occurs. marine pollution caused prevalent accident of red tide, destroyed mangroves, coral reefs, seagrass, the keen drop in offshore fish and fishery losses.
(j) the transboundary movement of hazardous waste
is defined in the hazardous waste other than radioactive waste, with the chemical play or noxious, gunpowder, corrosive, and other human characteristics of the living environment of disadvantageous waste. the United States Resource Conservation and Recovery Act stipulates that hazardous waste is a so-called solid waste and a mixture of several solid, because of its high volume and concentration, may cause or lead to additional human mortality, or cause serious illness or paralysis is difficult to remedy waste.
