Examples of human protection and destruction of the environment

In ancient China, our ancestors had realized the importance of protecting the environment. Here are some examples of protecting the environment.

1. Mencius' practice of protecting the environment;

There are many records in Mencius Hui Liang Wang Shang. One of the paragraphs reads:? "Don't go against the farming season, the valley can't win food. Countless people can't enter the bay pool. Fish and turtles can't beat food. Axe gold gets into the mountain in time, and mywood can't be used. ? From his remarks and the example of Li Ge above, we can see that people in the pre-Qin period emphasized the utilization of resources, which should be reasonably grasped according to the "weather". In order to make biological resources as renewable and sustainable as possible. Similar remarks can be easily found in other works of pre-Qin philosophers.

2. Xunzi's practice of protecting the environment:

Xunzi, a famous thinker in the Warring States period, wrote: "Today is the raw grain of the earth, and people are good at it, so the number of pots per mu is one year old _ and it is recovered, and then the number of melons, peaches, dates and plums is counted as pots and drums. Then, measure the quantity with meat and vegetables. Then six kinds of animals and wild animals-one is a race, and the giant fish, tortoise, loach and herring get together at different times. Then the birds are like a sea of smoke. Then insects are born in it, and countless people can eat each other. Obviously, wildlife resources and agricultural production are considered as important components of economic production.

Mencius and Xunzi advocated rational utilization of resources and sustainable development.

In recent years, due to the excessive utilization and development of nature by human beings, the temperature has risen sharply, smog has filled the sky, and sandstorms have struck. The following are examples of human destruction of the environment.

1. Global warming event

The earth is getting warmer. The thawing period of ice and snow in spring is about 9 days earlier than that of 150 years ago, but the starting time of frost in autumn is about 10 days. The climate will be warmer, glaciers will melt and sea level will rise, leading to the loss of coastal wetlands, mangroves and coral reefs. Seawater intrudes into the fresh groundwater layer along the coast, and the coastal land is salinized, which leads to the imbalance of natural ecological environment in the coast, estuary and bay, and brings great disasters to the coastal ecological environment.

The water area has increased. Water evaporation is also more, the rainy season is prolonged, and floods are more frequent. The chances of being flooded increase, the degree and severity of being affected by heavy rain increase, and the life of reservoir dams is shortened. Many small islands will disappear without a trace, and germs will spread the epidemic through extreme weather events, which will do harm to human health.

2. Waste and pollution of water resources

China is the country that uses the most water in the world, and it is also one of the countries that waste the most water resources. Agricultural water accounts for about 72% of the total water consumption, but only 1/? About 3, most of the losses are in the process of water supply and flooding.

According to statistics, the water consumption for car washing in Beijing in just one year is equivalent to the water storage capacity of one Kunming Lake or six North Seas. In the late 1980s, a farmer in Kunming poured a truck full of waste dyes into Panlong River, dyed the river red, and closed the waterworks for one day. One person pollutes a river. In the Huaihe River area with the most serious water pollution, 6.5438+0.8 million tons of serious pollutants enter the Huaihe River every year. Residents on both sides of the strait are prone to cancer and have a hard life; ? Today, what we see is still the heavily polluted Huaihe River, and what we hear is the call of/kloc-0.5 billion people in the Huaihe River Basin for blue sky and clear water, which leaves us with profound thoughts on the long-term control of Huaihe River pollution.

The forest was destroyed.

The global forest is facing an unprecedented serious crisis. Eight thousand years ago, the global forest covered nearly half of the earth's land. Today, the only remaining virgin forest in the global forest accounts for only 7% of the earth's land area. In the past thousands of years, global forests have provided habitats for millions of animal and plant species and all the resources needed by indigenous people who depend on forests for survival.

China's forest coverage rate is only? 13.92%, and the per capita forest area is only 17.2% of the world average. According to relevant data, China consumes 45 billion pairs of disposable chopsticks and wood/kloc-0.33 million cubic meters every year. To cut down about 25 million trees, it is necessary to destroy 146 square kilometers of forest. Disposable wooden chopsticks are widely used.
