Unfortunately, the overabundant use of plastic bags here, as well as the eco-unfriendly product packaging used in Thailand, is still a big problem. For example, in franchised convenience stores, it's common to see clerks putting each item into separate plastic bags, and then enclosing it all in one big non-biodegradable sack. Even worse, much of the product packaging here includes layer-upon-layer of plastic and styrofoam.
It's nice to see many Thai people walking around with natural cloth bags that read, "Say No to Plastic" or, "Save the Planet", even if it's just a trend (hopefully, it'll last). As individuals, we can each do our part if we cut down on using harmful materials. But, businesses here, big and small, need to get into the act, too.
