Advantages and disadvantages of garbage classification

1. Disadvantages of garbage classification

First of all, it will increase the amount of garbage buried or burned. In Beijing alone, garbage covers an area of 1 1,000 mu. The more garbage is burned, the more toxic gases are released and the more harmful dust is produced, which poses a great threat to our health.

Let's calculate how much waste of resources garbage will cause if it is not classified. According to the statistics of relevant departments, there are about 3 million tons of scrap steel and 6 million tons of waste paper in China every year. We often throw away more than 6 billion waste dry batteries, including 70,000 tons of zinc and 65,438+10,000 tons of manganese dioxide. If these resources can be reused, how much social wealth they will become. Not classifying not only wastes resources, but also pollutes the environment! Most batteries contain mercury, and when they are abandoned on the earth's surface, multi-layer metals will be oxidized and rusted. Mercury will slowly overflow from the battery, enter the soil or seep into the groundwater, and then enter the human body through crops or drinking water, damaging people's kidneys. Here, mercury can also be converted into inorganic mercury, which is converted into methyl mercury under the action of microorganisms and gathered in fish. After people eat this fish, methylmercury will do harm to human brain cells, seriously damage people's nerves, and even go crazy and die. The Minamata disease that caused a sensation in Japan was caused by methylmercury. A 1 battery rotted in the ground, and the mercury spilled from it was enough to permanently lose the agricultural value of square meters of soil. According to experts, 1 battery can pollute 600,000 cubic meters of water.

Two: the benefits of garbage sorting

The government should strengthen the enforcement of garbage sorting, and of course it is best to formulate a reward and punishment system, and the effect may be much more obvious. In addition, it is best to design a more convenient and eye-catching trash can, so that its logo is as popular as a traffic light, reminding everyone to sort garbage at all times. In this way, it can not only reduce pollution and protect the environment, but also save a lot of energy for the country.
