In the ancient times of China, the ancestors have realized the importance of protecting the environment, and the following are examples of protecting the environment.
1. What Mencius did to protect the environment:
There are a lot of records in this regard in the book "Mencius:King Hui of Liang". One of the paragraphs reads; ? "Do not go against the agricultural time, and the grain cannot be eaten. If you don't go into the bay, the fish and turtles can't be eaten. Fish and turtles cannot be eaten. If the axe and catty go into the mountains and forests at the right time, the timber and wood cannot be used. The following is an example of a book that was written by a man of the same name. From his words and the example of Liger above, we can see that the people of the pre-Qin Dynasty emphasized the use of resources and the need to grasp them in a reasonable manner according to the "time of the day", so as to regenerate biological resources as much as possible. so that biological resources could be regenerated as much as possible and utilized in a sustainable way. Similar statements can be easily found in other writings of the pre-Qin scholars.
2. Xunzi's approach to protecting the environment:
The famous thinker of the Warring States period, Xunzi, wrote; "Now is the soil of the birth of the five grains, people are good at governing, then mu a few pots, a year and a year _ and then gained, and then melons, peaches, jujubes, plums and the number of this to pots and drums. Then meat, vegetables and white vegetables to Ze amount. Then the six animals and beasts - one and plagiarized, soft-shelled turtles and fish and loaches, alligator and alligator in time and in groups. Then the birds and the eiders and the geese were like a sea of smoke. And then the insects were born among them, and the number of people who could eat and feed each other was countless. Obviously, wildlife resources and agricultural production are considered together as an important part of economic production.
Mengzi, Xunzi, advocating the rational use of resources sustainable development point of view.
In recent years, due to the overuse and exploitation of nature by human beings, it has led to a sharp rise in temperature, haze all over the sky, sandstorms, etc. The following are examples of human beings destroying the environment.
1. Earth Warming Events
The Earth is warming up, with the thawing of ice and snow in spring about nine days earlier than 150 years ago, while frosts start about 10 days later in fall. The climate is getting warmer, glaciers are melting, and sea level will rise, causing loss of ecological groups such as coastal beach wetlands, mangroves and coral reefs; seawater intrusion into the freshwater underground layer of the coast, and salinization of the coastal land, thus causing an imbalance in the natural ecosystem of the coast, estuaries and bays, and bringing great disaster to the ecology of the coastal zone.
The watershed area has increased. There is also more evaporation of water, the rainy season is lengthening, and flooding is becoming more frequent. There is a greater chance of flooding, a greater degree and severity of exposure to storms, and a shorter lifespan of reservoir dams. Many small islands will be left untouched, and pathogens are expanding epidemics and human health hazards through extreme weather events.
2. Water Waste and Pollution
China is the world's largest user of water, but also one of the most serious waste of water resources. Agricultural water consumption accounts for about 72% of the total water consumption, but the water that is really effectively utilized only accounts for about 1/?3 of the total water used in agricultural irrigation, and most of it is lost in the process of water delivery and diffuse irrigation.
According to statistics, Beijing's annual water consumption for car washing alone is equivalent to the water storage capacity of a Kunming Lake or six Beihai.
In the late 80's, a farmer in Kunming poured a crate of waste dyes into Panlongjiang River, which dyed the river red, shutting down the water plant for a day, "polluting a river by one person". The Huaihe River area, where water pollution is most serious, has 1.8 million tons of serious pollutants entering the river every year,? Residents on both sides of the river are suffering from cancer and hardship;? Today, we see is still a heavily polluted Huaihe River, heard the Huaihe River Basin 150 million people looking forward to the blue sky and clear water call, leaving us with the Huaihe River pollution is not cured deep thinking.
3. Forest destruction
The global forest is facing an unprecedented crisis. Eight thousand years ago, global forests covered nearly half of the Earth's landmass. Today, only 7 percent of the Earth's land area is covered by global forests, with remnants of the original forests. Global forests have provided habitat for millions of plant and animal species for thousands of years, as well as shelter and all the resources needed to sustain forest-dependent indigenous peoples.
China's forest coverage rate is only ?13.92 percent, and its per capita forest area is only 17.2 percent of the world's per capita level. According to relevant information, China's annual consumption of 45 billion pairs of drinking chopsticks, consuming 1.33 million cubic meters of wood, to cut down about 25 million trees, need to destroy 146 square kilometers of forest. The widespread use of disposable wooden chopsticks, to bring greater pressure on forest resources.
