We must start somewhere. While it would be better to reduce plastic to zero, the goal is not realistic. Plastic bottles are much lighter than the alternative I grew up with: glass. Less weight means reduced transportation costs. And, since both can be recycled, it’s time now we adopt the means for recycling we had when I was a kid: adding a deposit charge which can later be refunded when returned. It works well (not perfectly) for beer bottles and cans and wine & liquor bottles here in Ontario. It should definitely be extended to ALL plastic bottles.
Great debatable question here: Why are we NOT doing this in Ontario? (Canada, or wherever you are)
