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、首先是成本問題，畢竟現在市場上用的紙袋少了，公司的產量也少了。紙袋的價格比塑料袋貴得多。使用塑料袋的多公司行業發展水平高，所以價格會相對更劃算。通常，一個塑料手袋的價格是4-5美分，而一個紙袋的價格是4-50美分，間隔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. 環境污染。許多人說紙袋更環保，但覺得這個問題需要再次討論。英國有機化學研究所(British institute of organic chemistry)的統計分析顯示，生產1噸塑料比生產1噸紙節省50%的原材料，減少91%的電力消耗，減少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.

　　根據具體情況,塑料生產的關鍵原材料的原油,造成的環境污染是環境污染在整個生產過程中原油開采,一些有機化工廢水的排放處理的過程中,和塑料產品的解決方案。生產制造紙制品的關鍵是樹或草，而關鍵的環境污染問題是對花草樹木的砍伐，破壞森林，在加工過程中破壞某些生長迅速的綠色生態樹木和工業廢水。

　　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.
