What should we do in the face of global warming?

Global warming is a phenomenon related to nature, which is due to the continuous accumulation of greenhouse effect, resulting in the imbalance of energy absorbed and discharged by the geo-atmospheric system, and the continuous accumulation of energy in the geo-atmospheric system, leading to rising temperature and global warming.

Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have a strong permeability to visible light emitted by the sun, a strong absorption to long-wave radiation emitted by the earth, and a strong absorption of infrared radiation from the ground, leading to an increase in the temperature of the earth, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human survival.

On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises and the temperature difference with the ocean decreases, which in turn leads to the slow air flow and the smog can not be dispersed in a short time, which leads to the increase of smog weather in many cities and affects human health. Measures such as car restrictions and production suspension have only short-term and local effects, and cannot fundamentally change climate warming and smog pollution.

In a word, the harm of warming involves all aspects of human existence, from natural disasters to biological chain breakage.

So what methods and strategies have we formulated to deal with it?

First of all, scientists put forward an idea to build an artificial space ring around the earth, which is composed of small particles or spaceships to shield tropical sunlight and regulate the temperature of the earth. However, some opponents believe that this idea will definitely have some side effects. A belt of particles that can effectively scatter sunlight will make our night sky as bright as a full moon. In addition, the budget will be staggering, possibly reaching 6 trillion to 200 trillion dollars, which even NASA, the most well-funded scientific research institution in the world, can't afford. If the scattered particles are replaced by spacecraft, the budget may be less, and it is estimated that it can be reduced to about 500 billion US dollars.

Since the birth of the earth, the atmospheric temperature has fluctuated several times, and various factors such as solar radiation, cloud cover and greenhouse gases have affected or are affecting our climate. If you put a particle belt or spacecraft around the earth, a shadow will appear over the equator. In order to deploy these particles, you must use some special control spacecraft to look after the particle swarm like a sheepdog.

In the past century, the temperature of the earth has obviously increased, and this trend will continue in the next hundred years. Many studies have confirmed that the earth's temperature will rise by 1~20 degrees Fahrenheit in the next few centuries, the sea level will rise obviously, and some coastal cities will cease to exist. Some scientists have pointed out that reducing sunlight will reduce the temperature of the earth, and some ground or space systems can completely achieve this goal. However, some scientists pointed out that it is still impossible to calculate how much sunlight the earth can absorb and how much sunlight is reflected back into space, which is a key step in implementing the above plan.

American research shows that the activities of ancient farmers prevented the world from entering a new ice age. The results show that global warming caused by human activities is not a new phenomenon, and it may last for thousands of years. The British "Observer" quoted researchers as saying that prehistoric farmers who cut down trees and reclaimed the first field changed the content of greenhouse gases such as methane and carbon dioxide in the earth's atmosphere, and the global temperature gradually increased. Qian Wei Rudiman, a professor at the University of Virginia in the United States, said: "If it were not for the greenhouse gases brought by early agricultural activities, the current temperature of the earth would probably be the temperature of the Ice Age." Studies show that without human intervention, the earth will be 2℃ lower than that in the 20th century, and the spreading ice sheets and glaciers will affect most parts of the world.

Forests in the world are mainly divided into three categories: frigid (northern) forests, temperate forests and tropical forests. According to reports, today's forest ecosystem is gradually formed after 8000 years of evolution of nature. Nowadays, all virgin forests have become the targets of large-scale development and utilization of logging industry. In the tropics, many forests that disappeared in 2 1 century have been cut down in the past 50 years. From 1960 to 1990 alone, more than 450 million hectares of tropical forests were swallowed, accounting for 20% of the total tropical forest area in the world; Millions of hectares of tropical forests have been degraded by logging, farmland reclamation and mineral exploitation.

In addition, illegal logging and illegal trade in wood products continue to intensify all over the world, especially in developing countries with tropical forests and countries with poor government enforcement, such as Russia. This situation is further aggravated by the demand for cheap wood products in the international market.

By 2 100, the global temperature is estimated to rise by about1.4 ~ 5.8℃ (2.5 ~10.4 Fahrenheit).

We can start with the basic necessities of life:

Eat:

First, vegetarian food. Animal husbandry consumes a lot of food and beans, and also consumes a lot of valuable water resources; In order to graze cattle and sheep, raise pigs and chickens, the virgin forest was sacrificed, resulting in the greenhouse effect.

Second, eat less. Cooking at home, eating out is just right, and you can't finish it and pack it home.

3. 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, use a large number of pesticides and fertilizers, and pollute water sources and reservoir ecology).

Clothes:

Second, the demand depends on four factors, such as the number of laundry, the capacity of the family, lifestyle and economic situation, to determine the frequency of buying clothes, and try to control it as well as possible, not to overdo it (focusing on quality and light weight).

Third, the old clothes are newly worn:

1. Self-cognition: consideration of body shape, skin color and lifestyle.

3. 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. A small amount of clothes is a reliable accessory that highlights the artistic effect of dressing.

Live broadcast:

First, use more second-hand furniture (whether buying a house or renting a house, using more second-hand furniture can not only recycle and save resources, but also help each other and enhance interpersonal friendship if flea markets for regular second-hand goods exchange can be held in offices, communities and the Internet).

Second, use planting greening to do home decoration (don't do excessive decoration at home, be simple and natural. Home decoration does not necessarily need artificial materials, it is best to use 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's18th water shortage country, and South Taiwan Province Province is in severe drought, but our water demand has reached the standard of 20 1 1. The propaganda policy of water saving in France is "take a bath once a week"; If our water consumption continues to deteriorate, we will face the same situation.

Fourth, the power supply and air conditioning in the room are used centrally (try to turn on the air conditioning in one room as little as possible, and try to concentrate on office when there are few people, so as to reduce the amount of air conditioning and electric lights).

Ok:

First, take the stairs instead of taking the elevator (people who live in the building, whether in the office or at home, might as well take the stairs instead of taking the elevator if they are not in a hurry, which will save energy and exercise).

Second, go out and walk more, ride a bike, use the public transport system, drive less and ride a motorcycle.

Therefore, we should cherish the environment, defend our home on the earth and jointly create a better future.
