What are some tips on environmental protection?

1. When cooking, use less coal stoves and instead use liquefied gas. When cooking, don’t wait until the oil is so hot that it smokes before putting food in, so as to reduce air pollution as much as possible.

2. Plant a variety of flowers and bonsais on the balcony at home, clean the room frequently, and dry the quilt frequently to keep the air in the home environment fresh and pleasant.

3. Reduce noise pollution and try to lower the volume when talking or recording.

4. Dispose of waste correctly, classify domestic waste, and discharge domestic water reasonably.

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, not to burn garbage at will, to maintain the health of the family and maintain a clean environment.

7. Collect plastic bottles, waste paper, etc. and sell them to waste collection stations to reduce garbage emissions.

8. Pets kept at home should be well taken care of to prevent them from disturbing neighbors’ rest and causing fecal contamination, so as to maintain a harmonious living community and environment.

9. Rice washing water can be used to water flowers, wash vegetables, and flush toilets.

10. Put used batteries into recycling bins or collect them and send them to recycling stations.

Save electricity, protect resources and reduce pollution.

Electricity is something that every primary school student comes into contact with every day, and it is also inseparable from our daily study and life, but now the consumption is staggering. Therefore, every move when using electricity must be based on conservation.

In our country, power generation mainly relies on burning coal, and the coal on the earth is limited. At the current consumption rate, the world's coal will be consumed within 250 years. After that, we will have no coal left for our descendants.

Saving electricity means saving coal, and it also directly contributes to reducing air pollution. Because acid rain is formed by the burning of coal, it can strongly corrode buildings and acidify soil and water quality, leading to reduced food production and the death of vegetation, fish and shrimp. According to calculations, the economic losses caused by acid rain in southwestern and southern my country alone amount to 14 billion yuan every year.

Saving electricity can slow down global warming. Due to the large amount of carbon dioxide emitted by coal burning, it acts like a cover to block the heat from the ground from radiating to the sky, creating a greenhouse effect. If the earth's temperature rises, it will cause droughts or floods, and will also melt icebergs. If all the icebergs on Earth melted, lower countries and islands would disappear.

Those of us living today are bound to enter the next century, and many of them are vulnerable to the increasing global warming. 135,000 children in 192 schools in Germany have vowed to reduce harmful greenhouse gases in their communities by 10%. They replaced energy-saving lamps, refused to use air conditioners, gave up cars, and chose bicycles. After seven months of hard work, they have reached their goal.

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

Love nature, care for flowers, trees, and animals.

Carry out tree planting and green protection activities.

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

Today, through various media, everyone is becoming more and more aware of the existence of environmental and development issues. Many people have heard about problems such as the disappearance of tropical rainforests, acid rain, ozone layer destruction, global warming, sharp decline in biodiversity, poverty, refugee flows, and food crises. But for many people, these events occur far away and do not occur in a local environment.

However, if you look closely, you will find 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 current 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 to sustainable development is compared to a track, then there are no spectators outside this track. Everyone is an athlete.

Environmental and development issues are not only a matter for the government, but also a matter for everyone and individuals.

Environmental protection knowledge is one of the essential qualities for talents in the 21st century. In order to enable teachers and students to deeply understand and understand the importance of environmental issues, and to improve teachers and students' environmental literacy such as environmental knowledge, awareness, skills, attitudes, values ??and behaviors. In accordance with the "Action Outline on Environmental Education" issued by the State Environmental Protection Administration, the State Education Commission, and the Central Propaganda Department, as well as the instructions and requirements of relevant superior departments, combined with the actual situation of the school, in recent years, middle schools in the development zone have comprehensively carried out activities to create green schools. We will make unremitting efforts to include environmental education as a major event in schools, and truly integrate the understanding of environmental education into the hearts of teachers and students.

In the activities of creating a green school, the school always attaches great importance to environmental protection education for students, advocates green civilization in schools and families, and implements environmental protection actions. While focusing on popularization, we also pay more attention to the connotation and insist on instilling environmental awareness and environmental ethics in students in various fields such as moral education, scientific and technological activities, team activities, and social practice. After several years of exploration and practice, good results have been achieved and some experience worth promoting has been accumulated.

Give full play to the role of the main channel of the classroom and make use of all available conditions to enable students to effectively master the environmental protection content in various subject textbooks and cultivate students' environmental awareness.

Pay attention to "green" publicity

At present, the top priority of environmental education is to educate students to "learn to be human" and enable them to have "green minds". In order to enable students to acquire "green" awareness as soon as possible, the school actively creates a good atmosphere of public opinion, organizes students to consciously participate in planned environmental practice activities, and encourages them to improve their environmental awareness and moral level as soon as possible.

First of all, the school has increased investment in environmental protection. The library and reading room subscribe to a large number of books, newspapers and periodicals with environmental protection propaganda content every year. The school’s audio-visual education center has special environmental protection video materials. Each class All computers are equipped with environmental protection information software. We use our spare time to regularly organize students to watch, so that students can understand the current situation of the environment, learn environmental protection knowledge, and use their own actions to protect the environment. In addition, the school also has a special environmental protection window to regularly promote environmental protection knowledge to students and cooperate with the school's environmental education work; the school league committee uses the blackboard newspaper as a front line for environmental protection promotion and often organizes activities between each grade with the theme of environmental protection knowledge. The blackboard newspaper competition, through the competition, promotes the introduction of "green" into the class; the "Voice of Campus" radio station has opened a "Global Village for You, Me and Him" ??column, whenever there are environmental activity days: such as Arbor Day, Bird Love Week, World Water When Day, Earth Day, Environment Day, etc. come, we actively carry out environmental protection propaganda and call on each class to carefully write environmental protection broadcast scripts based on the holiday theme; and the school also sets up relevant environmental protection placards on campus, such as saving energy, reducing pollution, green Consumption, eco-friendly shopping, improving the environment, saving the earth, etc. Through the development of these activities, students can start from "I", start from small things, and keep the environment in mind in everything.

Environmental Protection Day

International Wetlands Day

February 2 is International Wetlands Day. According to the Convention on Wetlands of International Importance, Especially as Waterfowl Habitat, signed in Ramsar, Iran, in 1971, wetlands refer to “areas of permanent or temporary marshes, peatlands or waters with stagnant Either flowing, fresh, brackish or salt water, including waters not exceeding 6 meters at low tide." Wetlands play an important role in protecting biological diversity, especially the habitat and migration of birds.

World Water Day

On January 18, 1993, the 47th United Nations General Assembly made a resolution to determine March 22 of each year as "World Water Day". The resolution calls on governments of all countries to carry out some specific activities on this day based on their respective national conditions to raise public awareness. Since 1994, the Chinese government has changed the time of "China Water Week" to March 22 to 28 every year, making the publicity activities more prominent with the theme of "World Water Day".

World Meteorological Day

In 1960, the World Meteorological Organization designated March 23 as "World Meteorological Day" to increase public attention to meteorological issues.

Earth Day

In 1969, U.S. Senator Gaylord Nelson of Wisconsin proposed holding lectures on environmental issues on university campuses in the United States. Soon, Dennis Hayes, a student at Harvard Law School in the United States, expanded Nelson's proposal to hold large-scale community environmental activities across the United States, and selected April 22, 1970, as the first "Earth Day." On that day, more than 20 million people in the United States, including members of Congress and people from all walks of life, participated in this grand environmental protection event. Across the country, people chanted slogans to protect the environment, holding marches, rallies, speeches and propaganda in the streets and on campuses. Subsequently, the impact gradually expanded beyond the borders of the United States and received positive responses from many countries around the world, eventually forming a worldwide environmental protection movement. April 22 has increasingly become a global “Earth Day”. On this day every year, various mass environmental protection activities are carried out all over the world.

World No Tobacco Day

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

World Environment Day

In the 1960s and 1970s, with the deepening of environmental protection movements in various countries, environmental problems have become major social issues, and some cross-border environmental problems have frequently occurred appeared, environmental issues and environmental protection gradually entered the life of the international community. From June 5 to 16, 1972, the United Nations held the Conference on the Human Environment in Stockholm. Government representatives and private individuals from 113 countries discussed contemporary environmental issues in the world and strategies for protecting the global environment, and formulated the United Nations Conference on the Human Environment. Declaration and the 109-suggested "Action Plan" to protect the global environment, which proposed 7 common views and 26 common principles to inspire and guide people around the world to maintain and improve the human environment, and recommended that The opening day of this conference is designated as "World Environment Day". In October 1972, the 27th United Nations General Assembly passed a resolution designating June 5 as "World Environment Day". The United Nations formulates the theme of each year's "World Environment Day" in a targeted manner based on the world's major environmental issues and environmental hot spots that year. The United Nations system and governments of various countries carry out various activities on this day every year to promote the importance of protecting and improving the human environment. The United Nations Environment Program also publishes the "Annual Report on the Current State of the Environment" and holds an international conference to commend the "Global 500".

World Day to Combat Desertification and Drought

Since the increasingly serious global desertification problem continues to threaten human survival, June 17th has been designated as "World Day to Combat Desertification and Drought" every year since 1995. Combating Desertification and Drought Days”.

World Population Day

On July 11, 1987, marked by the birth of a Yugoslav baby, the world's population exceeded 5 billion. In 1990, the United Nations designated July 11 every year as "World Population Day".

International Day for the Protection of the Ozone Layer

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

World Animal Day

More than 100 years ago, the Italian missionary St. Francis advocated "giving thanks to the animals that give love to humans" on October 4. In order to commemorate him, people designated October 4 as "World Animal Day".

World Food Day

Food around the world is becoming increasingly in short supply as the population grows rapidly. Since 1981, October 16th every year has been designated as "World Food Day".

International Day for Biological Diversity

The Convention on Biological Diversity officially entered into force on December 29, 1993. To commemorate this meaningful day, the United Nations General Assembly passed a resolution to Since 1995, December 29th every year has been designated as the "International Biodiversity Day".

Dangers of Acid Rain

Acid rain usually refers to acidic precipitation with a pH value of less than 5.6, which represents the pH index.

Acid rain in my country (acid rain usually refers to acidic precipitation with a pH value below 5.6 indicating a pH index) is spreading and is the third largest acid rain area in the world after Europe and North America. In the 1980s, acid rain in my country mainly occurred in Sichuan, Guizhou and Guangxi, represented by Chongqing, Guiyang and Liuzhou, with an area of ??1.7 million square kilometers. By the mid-1990s, acid rain had spread to a vast area south of the Yangtze River, east of the Qinghai-Tibet Plateau, and the Sichuan Basin, with the acid rain area expanding by more than 1 million square kilometers. The acid rain areas in Central China, represented by Changsha, Ganzhou, Nanchang, and Huaihua, have now become the areas with the most serious acid rain pollution in the country. The annual frequency of acid rain in the central area is higher than 90%, almost to the extent that it is always acidic 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 my country. Acidic precipitation also occurred in some areas of North China and Northeast China. In 1998, more than half of the cities in the country, including more than 70% of the southern cities and the northern cities of Xi'an, Tongchuan, Tumen and Qingdao, suffered from acid rain. Acid rain has become a prairie fire in my country, covering more than 30% of the country's land area.

The harm of acid rain is multi-faceted, including direct and potential harm to human health, ecosystems and building facilities. Acid rain can reduce the immune function of children, increase the incidence of chronic pharyngitis and bronchial asthma, and increase the incidence of eye and respiratory tract diseases in the elderly. Acid rain can also significantly reduce crop yields, especially wheat. Under the influence of acid rain, yields can be reduced by 13 to 34%. Soybeans and vegetables are also susceptible to acid rain, leading to a decrease in protein content and yield. Acid rain is also very harmful to forests and other plants. It often causes the leaves of forests and other plants to wither and turn yellow, aggravates diseases and insect pests, and eventually causes widespread death.

Among the air pollution in China, acid rain and floating dust are the most important ones. Over the past decade, the problem of acid rain has become increasingly prominent due to increasing emissions of sulfur dioxide and nitrogen oxides. China is now the third largest acid rain area after Europe and North America.

The main distribution areas of acid rain in my country are the Sichuan Basin south of the Yangtze River, 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 is now also occurring in northern regions such as Houma, Beijing-Tianjin, Dandong, and Tumen.

Acid rain can cause great harm to forest plants. According to domestic simulation experiments on the impact of 105 species of woody plants, when the pH value of precipitation is less than 3.0, it can cause direct damage to plant leaves, causing the leaves to become chlorotic, turn yellow, and begin to fall off. The longer the leaves are exposed to acid rain, the more severe the damage will be. Field surveys show that in areas where the precipitation pH value is less than 4.5, a large number of yellow leaves appear and fall off in masson pine forests, Huashan pine and fir forests, and the forests decline in large areas. For example, in areas where the precipitation pH value is less than 4.3 in Fengjie County, Chongqing, the average annual high growth of 20-year-old Masson pine forests is reduced by 50%.

The impact of acid rain on forests is largely caused by the deterioration of the physical and chemical properties of soil. Under the action of acid rain, the nutrients potassium, sodium, calcium, and magnesium in the soil will be released and leached away with the rain. Therefore, long-term acid rain will cause a large amount of nutrients in the soil to be leached, causing a serious shortage of nutrients in the soil, thus making the soil infertile. In addition, acid rain can release aluminum in the soil from its stable state, causing an increase in active aluminum and a decrease in organic complex aluminum. The increase of active aluminum in the soil can seriously inhibit the growth of forest trees.

Acid rain can inhibit the reproduction of certain soil microorganisms and reduce enzyme activity. Nitrogen-fixing bacteria, bacteria and actinomycetes in the soil are all significantly inhibited by acid rain. Acid rain can also significantly increase forest pests and diseases. In Sichuan, the disease index of masson pine forests in heavy acid rain areas is 2.5 times that of areas without acid rain.

The harm caused by acid rain to China’s forests is mainly in the provinces south of the Yangtze River. According to preliminary survey statistics, the Sichuan Basin has the largest forest area affected by acid rain, accounting for approximately 280,000 hectares, accounting for 32% of the forest land area. The affected forest area in Guizhou is approximately 140,000 hectares. According to some research results, due to the decline in forest productivity caused by acid rain in the southwest region alone, 6.3 million cubic meters of wood were lost, and direct economic losses reached 3 billion yuan (based on 1988 market prices). It is estimated that the direct economic losses caused by acid rain in 11 southern provinces can reach 4.4 billion yuan. Most experts now believe that the ecological value of forests far exceeds its economic value. Although there is still some controversy over the calculation method of the ecological value of the forest, and the calculated figures are not yet universally recognized by society, it is almost unanimous that the ecological value of the forest exceeds its economic value. According to these calculations, the ecological value of a forest is 2-8 times greater than its economic value. If calculated according to this ratio, the economic losses caused by acid rain to forests are extremely huge.

What is Halon?

The so-called Halon (transliteration of Halon) is the trade name of 1211 and 1301 that we usually talk about. It belongs to a class of chemicals called haloalkanes. , mainly used as fire extinguishing agent. It extinguishes fires by destroying the complex chemical chain reactions of combustion or explosions. Halon fire extinguishing agent widely used in the fire protection industry is an ozone-depleting substance. When people use halon fire extinguishers to put out fires or train, halon gas is naturally released into the atmosphere. Halon contains chlorine and bromine. After being exposed to solar radiation in the atmosphere, it decomposes into chlorine and bromine free radicals. These chemically active groups combine with ozone and take away an oxygen atom in the ozone molecule, triggering a destructive chain reaction. , causing ozone to be destroyed, thereby reducing ozone concentration and creating an ozone hole. Halons can survive in the atmosphere for decades, and their destructive effects on the ozone layer in the stratosphere will last for decades or even longer. Therefore, the destructive effect of halons on the ozone layer is huge. Scientific research has proven that halons are one of the main culprits in destroying the ozone layer.
