Small knowledge of environmental protection

1. Use less coal stoves for cooking, and use liquefied gas instead. Don't wait for the oil to smoke when cooking, so as to minimize air pollution.

2. There are a variety of flowers and bonsai on the balcony at home, and the room is often cleaned and the quilt is often dried to keep the air in the family environment fresh and pleasant.

3. Reduce noise pollution, and try to reduce the volume when talking or playing on the tape recorder.

4. Properly handle wastes, classify domestic garbage and reasonably discharge domestic water.

5. Protect wild animals and plants, do not eat wild animals, and protect ecological balance.

6. Advise family members, relatives and friends not to smoke or burn garbage at will, so as to maintain the health of family members and keep a clean environment.

7. Collect plastic bottles and waste paper and sell them to waste collection stations to reduce waste discharge.

8. Take good care of the pets kept at home, so as to avoid affecting the rest of neighbors and fecal pollution, and maintain a harmonious living community and environment.

9. Rice washing water can be used for watering flowers, washing vegetables and flushing toilets.

1. Put the waste batteries into the recycling bin or collect them and send them to the recycling bin.

save electricity, protect resources and reduce pollution.

every primary school student is exposed to electricity every day, and we can't live without it every day in our study and life, but now the consumption is amazing. Therefore, every move when using electricity should start from saving.

in China, power generation mainly depends on coal burning, and the coal on the earth is limited. At the current consumption rate, the global coal will be consumed within 25 years. After that, we will have no coal left for our future generations.

saving electricity means saving coal, and it also directly contributes to reducing air pollution. Because acid rain is formed by coal burning, it can strongly corrode buildings and acidify soil and water, resulting in reduced grain production and death of plants, fish and shrimp. According to calculation, the economic losses caused by acid rain in southwest and south China alone amount to 14 billion yuan every year.

saving electricity can slow down global warming. Because of the large amount of carbon dioxide emitted by coal combustion, it blocks the heat from the ground from radiating to the outside of the sky like a cover, which has a greenhouse effect. If the temperature of the earth rises, it will cause drought or flood, and it will also melt icebergs. If all the icebergs on the earth melt, countries and islands with lower altitudes will disappear.

Living today, we are bound to enter the next century. Many of them are vulnerable to global warming. 135, children in 192 schools in Germany vowed to reduce the harmful gases that cause greenhouse effect in their communities by 1%. They put on energy-saving lamps, refused to use air conditioners, gave up cars and chose bicycles. After seven months of hard work, they have achieved their goal.

In a blink of an eye, we have entered a beautiful June, which is a great opportunity to plant trees and green the country. In order to create a good green home and protect the ecological environment, I suggest students:

Love nature, love flowers and trees and protect animals.

carry out tree planting and green protection activities.

Actively publicize environmental protection and bring environmental awareness to thousands of households

Nowadays, through various media, everyone is more and more aware of the existence of environmental and development problems. Many people have heard of the disappearance of tropical rain forests, acid rain, ozone layer destruction, global warming, sharp decline in biodiversity, poverty, refugee flows, food crisis and other issues. But for many people, these things happen in distant places, not in the local environment.

However, careful observation reveals that many of these problems occur locally, even on campus. Students and teachers in schools are consumers of resources. At the same time, as members of the community and present or future citizens, teachers and students are also responsible for community development and have the responsibility to contribute to the sustainable development of the community. If the road of sustainable development is compared to a runway, then there are no spectators outside this runway, and all people are athletes. The problem of environment and development is not only a matter for the government, but also a matter for everyone and individuals.

knowledge of environmental protection is one of the necessary qualities for talents in the 21st century. In order to make teachers and students deeply know and understand the importance of environmental problems, and improve their environmental knowledge, awareness, skills, attitudes, values and behaviors. According to the Outline of Action on Environmental Education issued by the State Environmental Protection Bureau, the State Education Commission and the Central Propaganda Department, and the instructions and requirements of the higher authorities, combined with the actual situation of the school, in recent years, the middle schools in development zones have carried out the activities of creating green schools in an all-round way. Putting environmental education into a major event of the school is always unremitting, and the understanding of environmental education is truly integrated into the hearts of teachers and students.

in the activities of creating green schools, schools always attach importance to the education of environmental protection for students, advocate green civilization in schools and families, and implement environmental protection actions. While doing a good job of popularization, we should pay more attention to connotation and insist on instilling environmental awareness and environmental ethics in students in moral education, scientific and technological activities, team activities, social practice and other fields. After several years of exploration and practice, we have achieved good results and accumulated some experiences worth popularizing.

Give full play to the role of the classroom as the main channel, and make use of all available conditions, so that students can effectively grasp the contents of environmental protection in the textbooks of various subjects and cultivate their awareness of environmental protection.

Pay attention to "green" propaganda

At present, the urgent task of environmental education is to educate students to "learn to be human" and make them have a "green mind". In order to make students have "green" consciousness as soon as possible, the school actively creates a good public opinion atmosphere, organizes students to consciously participate in planned environmental practice activities, and urges them to improve their environmental awareness and moral level as soon as possible.

First of all, the school has increased investment in environmental protection. Libraries and reading rooms subscribe to a large number of books, newspapers and periodicals with environmental protection propaganda content every year. The audio-visual education center of the school has special video materials on environmental protection. The computers in each class are equipped with environmental protection information software, and students are regularly organized to watch them in their spare time, so that students can understand the current environmental situation and learn environmental protection knowledge, thus protecting the environment with their own actions. In addition, the school also has a special environmental protection window to publicize environmental protection knowledge to students regularly to cooperate with the school's environmental education work; The Youth League Committee of the school regards blackboard newspaper as the front position to publicize environmental protection, and often organizes the evaluation of blackboard newspaper with environmental protection knowledge as the theme among all grades, so as to promote "green" into the class through evaluation; The "Voice of Campus" radio station has set up a column of "You, Me, He and the Global Village". Whenever environmental activity days, such as Arbor Day, Bird-loving Week, World Water Day, Earth Day and Environment Day, come, they actively promote environmental protection and call on all classes to carefully write environmental protection radio drafts according to the theme of the festival. In addition, the school also set up environmental protection placards on campus, such as saving energy, reducing pollution, green consumption, environmental shopping, improving the environment, saving the earth and so on. Through the development of these activities, let students start from "me", start from small things, and take the environment in mind everywhere.

Environmental Protection Day

International Wetland Day

February 2nd is the International Wetland Day. According to the Convention on Wetlands of International Importance Especially as Waterfowl Habitat, signed in RAMSAR, Iran in 1971, a wetland refers to "a long-term or temporary swamp, peat land or water zone with static or flowing, or a fresh water, brackish water or salty water body, including a water body less than 6 meters at low tide". Wetlands play an important role in protecting biodiversity, especially the survival and migration of birds.

World Water Day

On January 18, 1993, the 47th United Nations General Assembly made a resolution to designate March 22nd as World Water Day every year. The resolution invites governments to carry out some specific activities on this day according to their national conditions in order to raise public awareness. Since 1994, the Chinese government has changed the time of "China Water Week" to March 22-28 every year, making the publicity activities more prominent on the theme of "World Water Day".

World Meteorological Day

In 196, the World Meteorological Organization designated March 23rd as "World Meteorological Day" to raise public awareness of meteorological issues.

Earth Day

In 1969, Gaylord Nelson, a senator from Wisconsin, proposed to hold lectures on environmental protection in American universities. Soon, Dennis Hayes, a student of Harvard Law School in the United States, extended Nelson's proposal to hold large-scale community environmental protection activities in the United States, and selected April 22, 197 as the first "Earth Day". On that day, more than 2 million people in the United States, including members of Congress and people from all walks of life, took part in this grand environmental protection activity. Throughout the country, people shouted the slogan of protecting the environment, and marched, assembled, made speeches and publicized on the streets and campuses. Subsequently, the influence expanded and exceeded the national boundaries of the United States, which received positive responses from many countries in the world and eventually formed a worldwide environmental protection movement. April 22nd is also becoming a global "Earth Day". On this day every year, various forms of mass environmental protection activities are carried out all over the world.

World No Tobacco Day

In 1987, the World Health Organization designated May 31st as "World No Tobacco Day" to remind people to pay attention to the harm of cigarettes to human health.

World Environment Day

In the 196s and 197s, with the deepening of environmental protection movements in various countries, environmental problems have become major social problems, and some environmental problems that cross national boundaries frequently appear, and environmental problems and environmental protection gradually entered the life of the international community. From June 5 to 16, 1972, the United Nations held a conference on the human environment in Stockholm. Government representatives and non-governmental people from 113 countries discussed the contemporary environmental problems in the world and the strategies for protecting the global environment, formulated the Declaration of the United Nations Conference on the Human Environment and 19 "action plans" for protecting the global environment, and put forward 7 * * * identical views and 26 * * identical principles to inspire and guide all countries in the world. In October 1972, the 27th United Nations General Assembly passed a resolution to designate June 5th as the "World Environment Day". According to the world's major environmental problems and hot spots in that year, the United Nations formulated the theme of "World Environment Day" every year. Every year, the United Nations system and governments all over the world carry out various activities on this day to publicize the importance of protecting and improving the human environment. At the same time, the United Nations Environment Programme publishes the Annual Report on the Status of the Environment and holds an international conference in recognition of the "Top 5 in the World".

world day to combat desertification and drought

since 1995, June 17th every year has been designated as "world day to combat desertification and drought" because the increasingly serious global desertification problem is threatening the survival of mankind.

World Population Day

On July 11th, 1987, marked by the birth of a Yugoslav baby, the world population exceeded 5 billion. In 199, the United Nations designated July 11th as World Population Day.

International Day for the Protection of the Ozone Layer

On September 16th, 1987, 46 countries signed the Montreal Protocol on Substances that Deplete the Ozone Layer in Montreal, Canada, and began to take concrete actions to protect the ozone layer. The United Nations set up this commemorative day to arouse people's awareness of protecting the ozone layer and take concerted actions to protect the earth's environment and human health.

World Animal Day

More than 1 years ago, Italian missionary Saint Francis advocated "thanking the animals who gave their love to mankind" on October 4th. To commemorate him, people designated October 4th as "World Animal Day".

World Food Day

With the rapid growth of population, the world's food is becoming more and more in short supply. Since 1981, October 16th has been designated as "World Food Day".

International Biodiversity Day

The Convention on Biological Diversity came into effect on December 29th, 1993. To commemorate this meaningful day, the United Nations General Assembly passed a resolution to designate December 29th as the International Biodiversity Day every year from 1995.

harm of acid rain

acid rain usually refers to acidic precipitation with a Ph value lower than 5.6, which indicates the pH index.

Acid rain in China (acid rain usually refers to acidic precipitation with PH below 5.6, which indicates the pH index) is spreading, and it is the third largest acid rain area in the world after Europe and North America. In 198s, acid rain in China mainly occurred in Sichuan, Guangxi and Guangxi, represented by Chongqing, Guiyang and Liuzhou, with an area of 1.7 million square kilometers. By the mid-199s, acid rain had spread to the south of the Yangtze River, the east of the Qinghai-Tibet Plateau and the vast area of the Sichuan Basin, and the area of acid rain had expanded by more than 1 million square kilometers. The acid rain areas in Central China, represented by Changsha, Ganzhou, Nanchang and Huaihua, have become the most seriously polluted areas in China, and the annual frequency of acid rain in the central area is higher than 9%, almost to the point where it will be sour when it rains. The coastal areas of East China, represented by Nanjing, Shanghai, Hangzhou, Fuzhou, Qingdao and Xiamen, have also become the main acid rain areas in China. Acid precipitation also appeared in parts of North China and Northeast China. In 1998, acid rain fell in more than half of the cities in China, including more than 7% of the southern cities and Xi 'an, Tongchuan, Tumen and Qingdao in the northern cities. Acid rain has started a prairie fire in China, covering more than 3% of the country.

The harm of acid rain is various, including direct and potential harm to human health, ecosystem and building facilities. Acid rain can reduce children's immune function, increase the incidence of chronic pharyngitis and bronchial asthma, and increase the prevalence of eyes and respiratory tract in the elderly. Acid rain can also greatly reduce the yield of crops, especially wheat. Under the influence of acid rain, the yield can be reduced by 13% to 34%. Soybeans and vegetables are also vulnerable to acid rain, which leads to the decrease of protein content and yield. Acid rain is also harmful to forests and other plants, which often makes the leaves of forests and other plants yellow, aggravate pests and diseases, and eventually cause large-scale death.

Acid rain and floating dust are the most important air pollution in China. For more than ten years, the problem of acid rain has become more and more prominent due to the increasing emissions of sulfur dioxide and nitrogen oxides. Now China is the third largest acid rain area after Europe and North America.

The main distribution areas of acid rain in China are Sichuan Basin, Guizhou, Hunan, Hubei, Jiangxi, and coastal provinces such as Fujian and Guangdong. In North China, acid rain deposition is rarely observed, which may be due to less precipitation, low air humidity and low soil acidity in the north. However, it is worth noting that acidic precipitation has also appeared in northern areas such as Houma, Beijing-Tianjin, Dandong and Tumen.

acid rain can do great harm to forest plants. According to the simulation experiment of the influence on 15 woody plants in China, when the pH value of precipitation is less than 3., it can directly damage the leaves of plants, making them turn green and yellow and begin to fall off. The longer the leaves are exposed to acid rain, the more serious the damage is. Field investigation shows that the PH value of precipitation is small
