I definitely agree with reusing plastic stuff, but how many times do we do it. Rather than it is cheap and easily available, how many we throw them daily? How many times can you reuse them? Cotton bags at least are not made by destroying the plant (I think) and they are reusable many times. If they are torn we can stitch them or throw it in the earth they will degrade. Is that the case for Plastic ones.
I know politicians and corporations have power. But for some time let us stop pointing things towards them and do what we can do.
