Advocating environmentally friendly bags can only reduce part of the white pollution. Most people in our lives continue to use non-degradable plastic bags for convenience. They do not realize how harmful plastics are to the environment and ourselves.
Plastic bags are made of polymer polymerization. Common materials are polyethylene PE, polyvinyl chloride PE and polypropylene PO, etc. The plastic bags made of these materials are light and easy to carry, and can hold a lot of things with a large load-bearing capacity. Compared with cloth bags, baskets are much more convenient. Plastic bags are thin and easily scratched, cannot be reused, and have low recycling value. Although it is very convenient to use, it causes great pollution and waste to the environment.
(1) The pollution of plastic to the soil, the plastic bag has a stable structure and is not easy to be degraded by natural microorganisms. It accumulates in the environment and causes great pollution to the soil, which directly affects the absorption of nutrients and water by our crops, resulting in reduced agricultural production.
(2) The harm caused by plastic bags floating into rivers and oceans, (a large number of plastic micro-particles float on the water surface, hindering the transmission of light in the water, affecting the utilization of light by various organisms, and interfering with their normal life activities. Plastics contain toxic The chemical composition will pollute the water source, causing a large number of fish and shrimp to die.
(3) It poses a threat to the survival of animals. Sheep likes to eat the oily residue wrapped in plastic bags. It is easy to eat the plastic bags together. The eaten plastic bags slowly accumulate in the stomach and are difficult to digest, and the sheep’s stomach squeezes. Filled with plastic bags, they could not eat, and starved to death; the plastic was translucent in the water and was eaten by sea turtles as jellyfish.
(4) Plastic bags cause air pollution. There are generally two ways to deal with plastic bags: collective burial and incineration. Collective burial. It takes more than 200 years for plastic bags to rot and seriously pollute the soil. Collective burning of plastic bags will emit toxic gases and harmful smoke and produce a greenhouse effect.
For our planet, do not use single-use plastic bags, and advocate the use of environmentally friendly bags.
