    高一必修1英语第三单元作文1

    Look out, there are only concave ground skin, large swaths of forest are cut down, become people's life wood products. People have been displaced by herds of animals for their own sake. It's not a false fantasy, it's a bloody fact.

    Once upon a time, many animals and plants in the world were destroyed, and so many animals and plants were endangered. Why? This is all because human beings are cutting trees and destroying the ecological environment, which is the root cause.

    Land resource is one of the three major geological resources (mineral resources, water resources, land resources) and is the most basic resource and labor object of human production activities. Human land use degree reflects the development of human civilization, but also cause direct damage to the land resources, the main show is unreasonable reclamation plant caused by soil erosion, land desertification, soil secondary salinization and soil pollution, soil and water loss is particularly serious, but facing the world today and a serious crisis. It is estimated that the amount of topsoil in the world's arable land is about 23 billion tons per year.

    Some argue that acid rain is a silent crisis, and the worst environmental threat we've ever seen, an invisible enemy. This is not alarmist. As industrialisation and energy consumption increase, acid emissions are also increasing, and they enter the air, forming acid rain through a series of functions.

    Although the red tide has been around since ancient times, with the rapid development of industrial and agricultural production, water pollution is becoming more and more serious, and the red tide is becoming more and more serious. Since the first report in 1933, there have been 194 large-scale red tides since 1994, including only four in the 1960s and 157 in 1990. Oil pollution is very harmful to water quality and aquatic life. The oil that floats on the surface of the water can quickly spread, forming an oil film, which prevents the surface from contacting with air, and reduces the dissolved oxygen in water. Oil contains polycyclic aromatic hydrocarbons, which can be harmful to human health after the accumulation of aquatic organisms. Sulfur dioxide is mainly produced by burning fuels such as coal and fuel, followed by nature, such as volcanic eruptions and forest fires. Sulfur dioxide is strongly irritant to the conjunctiva and upper respiratory tract of the human body, but can be damaged by inhalation tube and can cause bronchitis, pneumonia and even pulmonary edema respiratory paralysis. In the short term, the mortality rate of the elderly or chronic patients with the concentration of 0.5mg/m3 air is higher and the concentration is higher than 0.25 mg/m3, which can aggravate the condition of the respiratory diseases. The number of people with prolonged exposure to 0.1 mg/m3 of air was increased. In addition, sulfur dioxide can cause corrosion, peeling, fading and damage to metal materials, housing construction, cotton spinning fabrics, leather paper and other products. It can also turn yellow or even die.

    Protecting the environment is everyone's responsibility.

    Today, China's economy has made the great achievement. More and more foreign people come to China to seek for cooperation. It is true that people's life standard has been improved a lot during the last decades, but the environment has been polluted badly. When I was very small, I could see the green trees and clean water around my hometown, but now, the river becomes smaller and the rubbish can be seen everywhere. I feel so sad about it. We have sacrificed so much to chase the profit.

    If we can't save the environment, we won't live the comfortable life. For us, we should not throw away the rubbish and plant more trees. The little things we do will make a great difference.

    As we all know, the environment around us is getting worse and worse. In some places we can't see fish swimming in the river or trees on the hills. Bird there is less and less fresh water in the world.Some people even have no clean water to drink. So I think we must do something to protect the environment. But what can we do? How to protect our environment? For example, we can go to school on foot or by bike instead of taking a car. We had better use shopping basketbets instead of plastic bags when we go shopping. We should use both sides of the paper when we write. Do't use paper cups. At our school dinning room, use our own bowls and chopsticks instead of disposable ones. We can reuse the water and save the electricity.In a word, if everyone pays more attention to ourenvironment, there will be less pollution and our life will be better.

    "There is only one earth", I hope everyone will protect our environment well.
