What other measures do you know to protect forests? Rejecting disposable chopsticks "The production and use of wooden disposable chopsticks objectively consumes a lot of wood resources, especially wooden disposable chopsticks belong to disposable consumption, which not only wastes wood resources, but also pollutes the environment."

-Minister of Finance, March 2005.

Consuming disposable chopsticks is a waste. When Chinese people go to China restaurants overseas, they may think: Why don't people use disposable chopsticks? China's per capita forest resources are lower than most countries in the world. In contrast, it should be strange for foreigners to come to China: Why do people in China use disposable chopsticks? FSC is a country with the strictest certification system for forest management and forest products processing trade in the world. Please try to buy products with FSC logo. In June, 2007, Greenpeace issued "Good Wood, Good Home-Green Wood Purchasing Guide" to help consumers make judgments. At present, you can go to B&; Q) Buy FSC certified wood products from IKEA. Personal environmental protection paper reducing paper use is something we can do at any time. How to be an environmentally friendly paper consumer? First of all, we can reduce unnecessary consumption. In addition, we can use recycled paper and paper produced by environmentally friendly raw materials (such as FSC certified wood) to ensure that the paper will not come from tree species with protective value or cause endangered animals to lose their habitat, and we can promote environmentally friendly production in the paper industry. Office environmental protection paper Every year, a large amount of wood from virgin forests is used to produce paper. For most of us, it is incredible to cut down hundreds of years old trees to make copy paper. However, such things happen every day in many areas, including China. You and your colleagues in your office can help change this damage. Forest is one of the most important natural resources for human beings. It not only provides us with wood and other forest by-products, but also has the functions of soil and water conservation, climate regulation, medical care and national defense, and is also a natural gene bank. However, forests are suffering unprecedented disasters. The main problems of China's forest resources are as follows: First, the per capita forest resources are very low. Compared with developed countries in forestry, there is a big gap. Second, the geographical distribution of forest resources is very uneven. Third, the volume of mature and over-mature forests in timber forests continues to decrease. Fourth, the quality of forests is not high. Fifth, the area of forest land has been seriously reversed. In order to prevent human friends from disappearing, how can we protect the forest? First of all, it is forbidden to cut down trees indiscriminately and change the backward concept of "relying on mountains to eat mountains". The forest on the mountain is not only handed down to you by "God", but also left to future generations. If all the trees are cut down now and the mountains are bald, it will bring disasters such as "mudslides" in a few years. At the same time, a number of forestry ecological engineering plans have been formulated and implemented to vigorously plant trees and protect the ecological environment. The "Three North" Shelterbelt System Project, which started at 1978, has managed many desertified lands from Heilongjiang to Xinjiang in the past 20 years. In addition, there are projects such as shelterbelt system in the middle and upper reaches of the Yangtze River and coastal shelterbelt system. And in line with the theme of hosting the Green Olympics in 2008, Beijing * * * Garden Department plans to carry out large-scale greening, and strive to make the green coverage rate of the planned construction areas in the city reach 45%. In fact, the protection of forest resources should "start from' small'"! "Small" has two meanings: the first is children, who have developed a good habit of protecting forest resources since childhood. When he grows up, protecting forest resources becomes a responsibility, and he has always been concerned about the existence of forest resources; The second is trivial matters. If we can't protect forest resources indirectly in ordinary trivial matters, then we can't protect forest resources better when we really need to protect them! In our daily life, there are too many places to protect forests! From cutting down trees to banning the use of disposable goods, all these can protect forest resources. However, relying on one person's strength is not enough. Protecting forest resources is everyone's responsibility! To this end, we primary school students can write some slogans that advocate everyone to protect forest resources, such as "leaving blue sky, clear water and green space to future generations" and so on. In this way, people can see these slogans anytime and anywhere to remind themselves: protect forest resources! I once saw a relationship diagram: people → from → people ↓ use ↓ use ↓ forest → wood. This diagram means that there are more and more people on the earth, but there are fewer and fewer forests. What's going on here? It turns out that people are constantly multiplying, and more and more people are cutting down indiscriminately regardless of the consequences, resulting in less and less forest resources, which may eventually disappear without a trace on the earth.

What else do you know about space knowledge? Please write down two cosmic spaces outside the earth's atmosphere, the whole space outside the atmosphere.

space

Physicists divide the atmosphere into five layers: troposphere (sea level to 10km), stratosphere (10 ~ 40km), mesosphere (40 ~ 80km), thermosphere (ionosphere, 80 ~ 370km) and outer atmosphere (ionosphere, over 370km). About 3/4 of the atmosphere above the earth. The outer edge of the stratosphere is the highest limit for an aircraft to fly with air support. Some high-altitude rockets can enter the middle layer. The lowest orbit of the satellite is in the thermocline, and its air density is 65,438+0% of the earth's surface. At the altitude of 16000km, air continues to exist, even at the altitude of 65438+ 100000km. From a strictly scientific point of view, there is no clear boundary between airspace and outer space. The Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space pointed out that it is impossible to put forward precise and lasting scientific standards to divide the boundary between outer space and airspace. In recent years, it tends to take the minimum height of a satellite from the ground (100 ~ 1 10) km as the minimum boundary of outer space.

A long time ago, there was a beautiful little village. The river in front of the village is crystal clear, the sky is blue and far-reaching, the air is fresh and sweet, and there is a dense forest behind the village. The breath of spring is very strong in the big forest. Rows of towering trees raise their arms like soldiers in the big forest. There is a lake called Swan Lake. Its water is delicious. Small animals in the big forest like to drink water here. Spring breeze people wear long braids of willows, and small flowers come out of the bedroom, only to see them wearing colorful flower skirts. However, soon, it became another look. "Oh, my God! It turns out that people pour those white plastic bags and other colorful garbage on me for convenience, which is really ugly. " Swan Lake said; "Yes, look at me. I am uglier than you. That white plastic bag flies around in the sky and hangs on my beautiful long braid. " Willow complained. The bird almost suffocated and said angrily; "It stinks. I have to leave quickly." I'm going to be smoked to death, and that child is even worse. It hurts to carve me with a knife. "The towering tree painfully shook his head and sighed. A little lark flew by and said, "Oh, my God! Where is this? Am I in the wrong place? " With that, he flew away. An old tortoise crawled slowly. It's always slow, but today, he lifted his feet and ran away quickly. Soon, there was no laughter and no singing of birds in the big forest. Nature is very angry. He was banging on people's windows with a strong wind and dust, as if he were complaining to others. People realized that they had done something wrong. They went into the forest, picked up all the rubbish and threw it into the dustbin. They cleaned up the floating objects on Swan Lake. Soon, the birds returned here to sing, and the beautiful big forest recovered its former joy.
