Now, environmental protection has become a topic of concern to everyone in society. We are a country with limited resources, and everyone should protect the environment and resources.

For example, the plastic products in China have seriously polluted our environment and brought "white pollution". Plastic shopping bags are a kind of "white pollution". They are not only consumables in daily life, but also consume a lot of plastic shopping bags every year in China. Plastic shopping bags not only provide convenience for consumers, but also cause serious waste of energy resources and environmental pollution due to excessive use and insufficient recycling. In particular, ultra-thin plastic shopping bags are easily damaged and most of them are discarded at will, which has become the main source of "white pollution". Therefore, China has also taken a series of environmental protection measures, such as the "Plastic Restriction Order"-using environmental protection bags is a way to control "white pollution-plastic bags".

Using environmental protection bags has many advantages, such as: the service life is longer than that of plastic bags; . Can be recycled; Low price, easy to popularize and so on.

Nowadays, people mostly use environmental protection bags when shopping in supermarkets and shopping malls, thus reducing the use of plastic bags and better protecting the environment. But now many environmental protection bags are paper products. For example, kraft paper bags and plastic paper bags are all made of paper. I don't think it's very environmentally friendly, because paper is also made of trees. Now humans cut down trees to make environmental protection bags, and such environmental protection bags are also damaging greening and not environmentally friendly.

I think we should use more environmental protection materials when using environmental protection bags, such as non-woven bags, canvas bags, cotton bags and so on. These materials are very environmentally friendly.

Non-woven bag (also called non-woven bag) is a very suitable environmental protection bag, because it is not only beautiful in appearance, durable, breathable and reusable. After the release of the plastic limit order, plastic bags will gradually withdraw from the packaging market, and some markets will be replaced by reusable non-woven shopping bags. Compared with plastic bags, non-woven bags can print patterns more easily and show colors more vividly. Coupled with this reusable feature, it is selected by many markets, supermarkets and shops.

Although non-woven bags are environmentally friendly, they are also selected by various businesses. However, this kind of bag also has a problem-the price is more expensive than plastic, which increases the operating cost for the owner. For example, if a household sells a catty of vegetables, the profit may be only 1 cent, so it is almost unnecessary to calculate the cost with ordinary plastic bags, but if you use environmentally-friendly non-woven plastic bags, you can hardly make money. Therefore, reducing the use cost is the key. Therefore, on the current environmental protection bag, many merchants print advertisements on the "environmental protection bag" to offset the use cost with advertising fees.

The most important thing is that mankind should save energy, protect the environment, reduce plastic pollution, promote comprehensive utilization of resources and protect the ecological environment.
