C
Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein’s jobs is defending(辩护) an industry behind the plastic shopping bags.
Americans use more than 100 billion plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited(禁止) in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic - bag makers are hiring scientists like Stein to argue that their products are not as bad for the earth as most people believe.
Among the bag makers’ argument: many cities with bans(禁令) still allow shoppers to buy paper bags, which are easily recycled but require more energy to produce and transport. And although plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.
The industry has aimed at the product which has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the less plastic - bags will be used. However, longer - lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the earth than plastic.
Environmentalists don’t doubt these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.
