Energy saving composition 1 Energy saving and emission reduction is a theme that all of us are advocating, but it is useless to always take these principles and university questions as slogans. We need Qi Xin to work together to start with the small things in life, so that everyone can save a little every day. For example, office workers who are close to home can ride bicycles instead of driving to work, and choosing trains instead of planes for short trips can save a little for everyone in the world in one day.
Usually, when you take out the garbage in your community, you may find that most communities have at least four side-by-side trash cans, which will read: recyclable garbage, kitchen garbage, harmful waste and other garbage. This is the garbage classification now. In the past, in a corner of the community, you might see a pile of dirty garbage dumps there, with bugs and flies flying around and stinking, and you don't want to look twice. This is the traditional garbage disposal method-landfill, which will pollute the environment very seriously. Now with garbage sorting, it can reduce the floor space and environmental pollution, and also turn some recyclable garbage into treasure. Creating a garbage-free society really only needs us to lift a finger.
Whether housewives or professional women, most of them like shopping on weekends, and part of shopping is shopping in the vegetable market. When you are going to the market to buy food, you'd better bring your own shopping bag or reuse plastic bags, which will cause huge waste of resources. In addition, one side of the soil and water to support one side, we should try to eat local food. Of course, food should also pay attention to quality.
Saving water resources is an important issue that our country attaches great importance to. There is a well-known water-saving slogan: "Don't let your tears become the last drop of water on the earth". In fact, this is not an exaggeration. When the water resources are really gone, it's too late for you to cry. At that time, what good life can we talk about? In fact, Taomi water is a great detergent, which can be reserved for washing dishes. Water for washing hands, bathing, washing clothes and vegetables and relatively clean dishwashing water can be collected to wash rags, floors and toilets.
There are many beautiful, cool, fashionable and expensive cars and sports cars on the market now, and many rich people, big and small, have to spend this money to buy a "face". But is this really the so-called "face"? This is vanity, waste and luxury. Cars should be environmentally friendly, generous, dignified and practical, and reduce carbon dioxide emissions. Environmentally friendly gasoline and diesel can improve the performance of cars. It can clean the engine of the car, reduce the friction of the engine and make the fuel burn more fully, thus reducing air pollution. In addition, I want to tell those rich people that people will not respect you and worship you because you are rich and have a lot of money. Only by dressing solemnly and neatly and behaving politely and appropriately can we truly have dignity and face.
At present, it is the period when the winter tiger is raging, and it is either snowy, cloudy or sleet. In this weather, as long as it is a family with a little well-off foundation, it will turn on the air conditioner to keep warm. But as long as you do more exercise and check whether the gap between doors and windows is closed, you can reduce the time and frequency of turning on the air conditioner. Also, even in winter, you need to open the window to ventilate and let the air circulate. You can't stay together all the time, or you will catch a cold.
Let's keep a sensitive heart of loving ourselves and respecting life, listen to the voices of the earth residents, protect our only earth, and help ourselves, others and the earth together!
I found in a table that the human body is 65% water. Our bodies need a lot of water to keep healthy. If we lack water, we will die of thirst. Therefore, it can be seen how important water resources are to human life, and we must save water resources to protect human living space. So much water is polluted. Who polluted it? Facts have proved that those shameful things were done by us humans. From time to time, we will see people spraying pesticides on vegetables and melons in fields full of vegetables. Their purpose is to prevent insects from biting leaves; However, this behavior has caused serious agricultural pollution. Pollution is not only agricultural pollution, but also industrial pollution and domestic pollution, so the state calls on us to save water resources.
Usually, when we brush our teeth, the toothbrush is serving us, but the faucet is running with unnecessary water resources, so we should save water resources and let the previously wasted water come back to us, as well as washing vegetables, mopping the floor, watering flowers and washing cars. It can be seen that in our daily life, a lot of water is wasted, so we should try to waste it. In a small pond, we can often see many dead fish floating on the water, and from time to time there are waves of unpleasant smells floating from the pond; In a mangrove field, we can see that all mangroves have died. This is because the water has been polluted. So, we saw this muddy water. It can be seen that the environment where we grew up has been ruthlessly retaliated by nature. Let's work hard, for our growing environment and our beautiful home, come on!
Where we live, there is not only a lack of water resources, but also a lack of fresh air. Through hard work, I found a composition about the volume of various gases in the air. 78% is nitrogen, 2 1% is oxygen, and 1% is other components. Oxygen is a gas that supports combustion in air, and it is air mixed with various gases. Oxygen accounts for about 10% of the air volume.
Air is also the source of our life. Almost all living things on earth need air. Clean air is good for our health. The polluted air contains a lot of harmful substances. When air pollution is serious, it will endanger human health and plant growth. We feel very uncomfortable when we hold our breath. There are many things that can prove that air is the source of life. On the high mountain, we can see some climbers wearing oxygen masks trying to climb to the top. Also, if the air in our vase is pumped out, the flowers in the vase will wither in a few days. Therefore, through the above examples, we can confirm that air is the source of life.
Beautiful forest has many reputations, including oxygen factory, natural air conditioning gas, green water storage, air purifier and so on. -On busy roads, the exhaust gas emitted by cars will paralyze people's nerves, cause itching, damage the brain, lead to memory loss and even lead poisoning. In order to make the air fresh, we must save energy and reduce emissions. For the heavily polluted factory and automobile exhaust, we must spare no effort to update the equipment and put an end to pollution. For automobile exhaust emissions, we should try to use public transportation to reduce emissions, so that we can have a living space with bluer sky, brighter sunshine, brighter flowers, greener grass and clearer water.
Every drop is our hope. Every drop can save hundreds of people. We must cherish every drop of water. If there is no water, we humans may die of thirst. If there were no water, there would be no such beautiful world as ours. We should cherish every drop of water and every tear.
I remember when I was 10 years old, my sister and I liked playing with water very much, and we were called "masters of playing with water". One day, while my aunt was away, we began to play with water. First of all, we fill each basin with water to make a' back bounce', pick up the bottle and throw it at each other. When we are tired of playing, we all have a rest. Unexpectedly, since my sister played a sneak attack, I also fought back, and finally our clothes were all wet. I had a brainwave and thought of another way.
I knew I wouldn't go if I turned down the water meter I told my sister to turn down the water. My sister didn't believe me and asked in surprise, "Can you really keep the water meter from running?" "Don't believe me, try it yourself!" Just like I said. I mysteriously said to my sister, "I finished washing my face yesterday, didn't turn off the tap, and the water meter didn't go." My sister said happily, "Then let's get water quickly!" But I frowned and said, "But it's too slow!" "Never mind, take your time!" After our parents came back, we struggled to keep our parents a "secret", thinking that they would praise us. Who knows, dad said to us earnestly, "What are you doing?" This is stealing water. Who told you to do this? This is a waste of water. "After listening to my father's considerate words, my sister and I blushed at once.
Water is an indispensable part of human beings. We shouldn't let the last drop of water become our tears.
Water is not only an important raw material for industrial and agricultural production, but also a precious natural resource for human survival. Without water, there would be no life, no good natural environment and no sustainable development of social economy. Nowadays, the world has entered the era of water shortage, and there has been a global water crisis. Compared with other countries in the world, the situation of water resources and water environment in China is even more worrying: First, the total water resources in China are seriously in short supply. 1998, China's per capita water consumption was 225 1 m3, which was only 1/4 of the world's per capita level. It is predicted that when the population of China increases to16 billion in 20xx, the per capita water resources will decrease to 1760 cubic meters. Secondly, the spatial and temporal distribution of water resources in China is also very uneven. The absolute amount of water resources in the west is less than that in the east, and the per capita amount in the east is less than that in the west, showing two reverse grade distributions. Thirdly, the water environment in China is deteriorating, which leads to the decline in the availability of water resources. With the economic development, population growth and the improvement of urbanization level, the demand for water resources in China will further increase in the future. How to solve the contradiction between the shortage of water resources supply and the increase of demand has become a major issue that needs to be studied and solved urgently.
In today's world, fresh water only accounts for 3% of the total water, of which two thirds is ice, which shows how poor the world water resources are now! "If there is only the last drop of water left on the earth, it will be our tears." Every time I hear this sentence, my heart is always nervous, afraid that such a day will come. Now, China is really developed: there are factories and tall buildings everywhere. With the increase of population, water resources are not available. Saving is enough, but people waste it wantonly. Coupled with pollution, China has thus become one of the 12 water-deficient countries in the world!
We must save water and don't let the last drop of water turn into our tears! !
