Governments around the world are pushing for an end to plastic bags. More and more businesses are changing to paper products. Using paper is thought to be better than plastic. However, it is harmful to the environment, too.
Firstly, paper bags are made from trees. Trees, as you know, are good for the environment. They can slow down climate change. An increase in the use of paper bags can cause more deforestation(毁林).
Secondly, the production of paper things requires more energy and water. About 10 percent more energy and four times as much water are used to produce a paper bag than a plastic one. You might say that we can use recycled paper to save that energy and water. This seems to be a good idea. However, it takes even more energy and water to go through the recycling process than to make a new paper bag. Products made from recycled paper are also often short- lived.
Furthermore, paper products are heavier than plastic ones. That means they require more fuel to transport. Seven trucks are needed to transport two million paper bags, while only one truck is needed to transport the same number of plastic bags. The increased weight also leads to a larger amount of waste once the bags are thrown away.
So, paper products are actually a lose- lose result for both the environment and businesses. They are more expensive than plastic products. A paper straw costs about 5 to 12 cents, while a plastic one usually costs only about 2 cents.
In my opinion, the most environment- friendly way is to avoid single- use things altogether. Products like glass water bottles and steel straws can be used over and over again. They are much better than either paper products or plastic products. By increasing the use of these items, you can greatly reduce your throwaway waste and truly make our earth a greener place!
