Plastic bag ban
Even when they are disposed properly, they  take many years to decompose. This generates a lot of garbage. In many cases, they are simply thrown away. This will pollute waterways. Thin pastic bags have been found in the oceans, where they affect the ecosystem of marine creatures. Several microbial species colonize on plastic particles making them more harmful. Plastic particles driven by winds form garbage patches in various parts of the oceans. The UN estimates that there will be more plastics than fish in the oceans by 2050 unless countries come up with urgent measures to promote efficient production, use and waste management of plastics throughout their life cycles.
