People have to find problems in their daily life. If people go to the supermarket, they usually show them plastic bags, but there are no paper bags. Many people say that paper bags are more environmentally friendly than plastic bags, so why don't shops sell paper bags instead of plastic bags?

　　1、是成本问题，毕竟现在市场上用的纸袋少了，公司的产量也少了。纸袋的比塑料袋贵得多。使用塑料袋的多公司行业发展水平高，所以会相对更划算。通常，一个塑料手袋的是4-5美分，而一个纸袋的是4-50美分，间隔10美分

　　1. First is the cost. After all, there are fewer paper bags in the market and the company's output is also low. Paper bags are much more expensive than plastic bags. Many companies using plastic bags have a high level of industry development, so the price will be relatively more cost-effective. Usually, the price of a plastic handbag is 4-5 cents, while the price of a paper bag is 4-50 cents, 10 cents apart

　　2. 环境污染。许多人说纸袋更环保，但觉得这个问题需要再次讨论。英国有机化学研究所(British institute of organic chemistry)的统计分析显示，生产1吨塑料比生产1吨纸节省50%的原材料，减少91%的电力消耗，减少75%的蒸汽排放。

　　2. Environmental pollution. Many people say paper bags are more environmentally friendly, but feel that this issue needs to be discussed again. According to the statistical analysis of the British Institute of organic chemistry, the production of one ton of plastics saves 50% of the raw materials, 91% of the electricity consumption and 75% of the steam emission compared with the production of one ton of paper.

　　根据具体情况,塑料生产的关键原材料的原油,造成的环境污染是环境污染在整个生产过程中原油开采,一些有机化工废水的排放处理的过程中,和塑料产品的解决方案。生产制造纸制品的关键是树或草，而关键的环境污染问题是对花草树木的砍伐，破坏森林，在加工过程中破坏某些生长迅速的绿色生态树木和工业废水。

　　According to the specific situation, the environmental pollution caused by the crude oil, the key raw material of plastic production, is the solution of the environmental pollution in the whole production process of crude oil exploitation, some organic chemical wastewater discharge treatment process, and plastic products. The key to the production of paper products is trees or grass, and the key environmental pollution problem is the cutting of flowers and trees, the destruction of forests, the destruction of some fast-growing green ecological trees and industrial waste water in the process of processing.
