Essay on science and technology-don't waste garbage

Do you know that?/You know what? Do you know that?/You know what? China wastes 25 billion worth of resources every year! These resources are neither oil nor natural gas, nor high-tech products, but domestic garbage produced by every family every day. Unfortunately, we didn't properly classify the garbage, which not only made the garbage that can be used but can't be used as the source of secondary pollution, but also caused a huge waste of resources!

Let's take a look at the consequences of all the domestic garbage mixed together! First of all, it will increase the amount of garbage buried or burned. In Beijing alone, garbage accounts for.

The land has reached 1 1,000 mu. The more garbage is burned, the more toxic gases are released, and harmful slag and dust are 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.

Since garbage sorting is so important, why can't everyone do it well? After investigation, we found that many people are afraid of trouble and have insufficient awareness of environmental protection. Another important reason is that there are few trash cans in streets and communities, which makes it difficult for people to form a good habit of garbage sorting.

Hey, can we say that continuing to mix these rubbish together will pollute the environment and waste resources? That won't do. We must find a way to solve it If the government strengthens the enforcement of garbage sorting, it is of course 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.
