Make it compulsary for dog poop bags on sale to be biodegradable. Bags should be biodegradable rather than degradable plastic.
Why is this important?
Some dog owners collect the dogs poop in a bag and dispose of inappropriately which unpleasent and is worst than not picking up the poop as the bag will remain for decades. Biodegradabale bags would be better for the enviroment if disposed of correctly or incorrectly.
