Plastic bags, really all plastic packaging, should be changed to biodegradable. Some plastics are carcinogenic (PVC) and don't break down for many thousands of years. The six huge gyres of floating plastic pollution in the world's oceans, and the loss of landfills within 10 years are very big and disgusting problems. The twice the size of Texas gyre between California and Hawaii is the worst. Waste is a function of population, and habits. California has converted to mostly 66% more per capita trash producing people (Mexicans, from 1995 research) from invasion and over-immigration in the past 25 years, and this is where most of the trash in that gyre comes from, by wind. Then we have places where, because the government went broke, trash has piled up 4 feet high with narrow paths through it, in Africa. I expect it to happen to California cities, too, as their state government goes further in the red. A portent for world conditions--broke governments and overflowing waste of all kinds, leading to a higher disease rate. Biodegradable packaging will help, some.
