Read： 704 Time：17months ago Source：Transform the World with Simplicity

As a general material, plastic is widely used in various fields, such as packaging, construction, electronics, medical, automotive and so on. There is no doubt that plastic is an important product of scientific and technological progress, accelerating the development of human society. However, as people pay more attention to environmental protection and plastic-related issues continue to be revealed, this seemingly "magical" material has gradually caused widespread controversy.

So, what exactly is plastic? Simply put, plastic is a plastic material formed by one or more types of polymer particles. Such polymers can be natural, such as natural rubber, or synthetic, such as polyvinyl chloride, polystyrene, etc. Then add additives, colorants, etc., after adding thermoplastic blending into a variety of plastic products.

plastics have many advantages, such as wear resistance, corrosion resistance, corrosion resistance, sound insulation, insulation, etc., which can replace traditional materials, reduce the weight of articles, and improve efficiency and convenience. But at the same time, plastic also brings a lot of negative effects, such as pollution, garbage accumulation, non degradable and so on.

plastic pollution has become its biggest "side effect". Plastic products contain some harmful substances, such as benzene, formaldehyde, lead, etc., if long-term exposure to these substances, will cause adverse effects on human health. At the same time, plastic products are discarded, will also cause pollution to the environment. Studies have shown that a large number of plastic products are thrown away by factories, individuals and society at will, causing more and more serious environmental problems. Plastic debris has even become a killer of marine life, causing serious damage to the ecological balance. The treatment of

plastic waste has become a worldwide problem. Because most plastic products are non-degradable, waste disposal becomes a serious problem. Plastic products are buried in the ground for hundreds or even thousands of years before they can be decomposed naturally. At the same time, garbage incineration will also release many harmful gases, such as sulfur dioxide and nitrogen oxides, which pose a threat to the environment.

in order to solve these problems, people need to take some concrete actions. For example, controlling the content of toxic ingredients from the source of material production, using degradable materials instead of plastics, enhancing garbage disposal capacity, and encouraging recycling and reuse. At the same time, it is also an indispensable way to improve the environmental protection awareness of individuals and society and vigorously promote the development concept of low-carbon ecological and environmental protection.

sum up, plastic, as a great invention brought about by scientific and technological progress, is not only conducive to the development of industry and life, but also has many problems and disputes. We need to understand and use this material correctly, pay more attention to its environmental and health problems, and take reasonable measures to ensure our quality of life and achieve the goal of sustainable development.
