Compare to people in western Europe, people in the United States or Asia pay less attention to the environment, I think. However, eventually, all people on this planet will have to pay more attention and efforts to preserve our environment, which is now rapidly changing.
Recently, I noticed that all grocery stores in San Francisco quite using plastic bags. Three years ago, most of shops uses the plastic bags, but nowadays they all use paper bags instead. I think this is a part of the environmentalism movement, which is hitting the city.
However, I got a fundamental question about this change. Are paper bags better for the environment than plastic bags?
Quote from Stranger in a Strange Land:
MSNBC provides an educational piece about the debate of whether paper or plastic bags are better for the environment with their Battle Of the Bags website.Paper bags are good because they are compostable, recyclable and made from sustainable resource, trees. However, it is also true that we need more energy to make paper bags than to make plastic bags. These energies are generated by burning oils, which destroys our environment. And cutting trees to make paper bags will increase greenhouse effects. Therefore, I personally do not have the conclusion which one is better, and do not totally support San Francisco's movement toward paper bags.
In the bottom line, bringing own reusable bags to grocery stores is the best way. Although, it is not convenient, I will load many reusable bags in my car trunk not to forget to bring.
