Geography is very practical. With the progress and development of mankind, geography has gradually integrated into our daily life. We used to think it was just an exam subject. However, I don't know that it is actually closely related to our lives. At the same time, it is also the most basic and important knowledge for us to build the motherland and protect the environment of the motherland. In the face of the motherland that has nurtured us for more than ten years, we may not be able to make any impassioned and well-known great contributions. However, we can build and protect our motherland bit by bit by making use of the geographical knowledge we know. You know, mastering a lot of life-related knowledge is not all about exam results, but about whether you can really understand and apply it to life and expand your thinking.
Through the study of geographical knowledge, we can understand the basic knowledge about the earth and the universe, world geography, China geography and local geography, and understand the problems of environment and development. It enables us to learn geography skills initially and learn a lot about the geographical knowledge, development degree, regional urbanization process, local customs and environmental problems of the motherland.
As far as the national conditions of China are concerned, the population problem is of outstanding significance. We know from the combination of high school textbooks (1, 2) and junior high school knowledge. China has a large population and rapid growth, which brings great pressure on resources, environment and economic development. Our generation is the future of the motherland. Through our study of geographical knowledge, we can plan how to use geographical knowledge and humanistic knowledge to solve or effectively alleviate our tired motherland from the beginning of contact.
We should know more and ask more questions. Take the world-famous Three Gorges Project of the Yangtze River as an example. Why was the dam built in Sandouping instead of Qutangxia? Only by asking more questions can we solve the problems in the discipline, understand more engineering principles and make better contributions to the construction of the motherland in the future.
In terms of resources; At present, the alarm of the world freshwater crisis has sounded, and "how to deal with the threat of water" has been prominently placed in front of people all over the world. China is a country with severe drought and water shortage. China's total freshwater resources are 2.8 trillion cubic meters, accounting for 6% of the world's water resources, ranking fourth in the world after Brazil, Russia and Canada. China's per capita water resources are only 2,300 cubic meters, which is only 1/4 of the world average, and it is one of the poorest countries in the world. Judging from the current development of 2 1 century, the three major problems, namely, flood disaster, drought and water shortage and deterioration of water ecological environment, especially the shortage of water resources, will increasingly become important factors restricting China's agricultural, economic and social development. The phenomenon of urban water shortage in China began in the 1970s, and then it expanded year by year. According to statistics, more than 400 of the 666 cities in China are short of water, with a daily water shortage of 65.438+0.6 million cubic meters and an annual water shortage of about 6 billion cubic meters. Due to water shortage, the annual industrial output value is more than 200 billion yuan. At present, there are still more than 30 million people and tens of millions of livestock in rural areas of China who have difficulty drinking water. In China, about14 people drink water that does not meet the hygienic standard, which directly affects people's health level.
Facing the problem of resources, we should learn from it and save resources according to our own national conditions. Such as; Israel, a West Asian country, makes full and rational use of water resources by increasing revenue and reducing expenditure, and its experience is worth learning from all countries.
Resources are the capital of a country's development. Without learning geography well and understanding the problems and utilization of China's resources, it is impossible to build the motherland.
At present, there are still important international issues; Environmental pollution. Humans have always thought that the water and air on the earth are endless, so they are not worried about sending tens of millions of tons of waste gas into the sky and dumping hundreds of millions of tons of garbage into rivers, lakes and seas. Everyone thinks the world is so big. What kind of waste is this? We are wrong, we know by studying geography; In fact, although the earth is large (with a radius of more than 6,300 kilometers), creatures can only live in the range from 8 kilometers above sea level to the seabed 1 1 km, and 95% of the creatures can only live in the middle range of about 3 kilometers. People have wantonly polluted this limited living environment from three aspects.
Environmental pollution has also caused great losses to our country. The annual cost of environmental pollution caused by economic development in China is close to 1 trillion yuan, and this figure is still increasing year by year.
The Environmental Economic Accounting Report of China in 2009 issued by the Environmental Planning Institute of the Ministry of Environmental Protection shows that the environmental pollution cost of China's economic development continues to rise. The pressure of environmental pollution control is increasing day by day. Since 2004, the cost of environmental pollution based on degradation cost has increased from 5 1 1.82 billion yuan to 970 1. 1 billion yuan. The cost of environmental deterioration in 2008 was 894.76 billion yuan.
At the same time, the total cost of environmental degradation and ecological destruction in 2009 was139162 million yuan, an increase of 9.2% over the previous year, accounting for about 3.8% of the GDP in that year.
Geography is an important subject that guides us to build and protect our motherland, and plays an important role in solving many important problems facing the world, so we should study geography well in order to build our great motherland.
