Yes they should be replaced with something more environmentally friendly, but what exactly? We got along just fine for so long using paper straws so why can we not go back to them? So many drinks available now would be impossible to consume with a paper straw, the Asian milk teas, frozen slushie drinks, smoothies, juice drinks with lots of pulp, thick shakes, anything in a tetra-pak, etc. Would be great if somebody could come up with a paper or cardboard straw that is rigid enough to last until I finish my drink before collapsing. Of course the government could just ban the production of those plastic straws but for many businesses those frozen slushie drinks are literally the most profitable item and the only thing that keeps their business going, in summer they sell hundreds of them every day. Same goes for plastic takeaway containers and shopping bags, there has got to be an alternative, if I have to pay an extra 20 cents for a rigid cardboard straw I would gladly do that.
