Even if they find alternatives for plastics people should be ready to accept it and go for alternatives
We do already have nice alternatives, including fully biodegradable plastic. But people don't use it because it is slightly more expensive, and a bit less durable.
Yes, that is true but if the alternatives are available in abundance, then there is a possibility that people might then go for alternatives. But change starts from the individual. We will try to use alternatives and there will be circumstances where we may find it difficult to avoid plastics. Execpt for those situations, it will be good to make it as a self descipline.
