I can't speak to straws specifically, but on the question of so-called single-use plastics or plastics in consumer goods, work was done by our industry with the support of the United Nations in 2016, and updated last year. It was done by Trucost. What it said was that there are replacements for many of the plastics that are of concern, including those top 10 in the European Union, but when you look at the alternatives, the environmental and economic costs will be over $400 billion, four times as much for those alternative materials.
That comes back to our point: We have to be cautious when solving a problem that we don't simply replace it with a bigger problem. There will be applications where perhaps aluminum is equivalent, but perhaps aluminum is also much more expensive. You need to look at the picture as holistically as you can before simply making a ban on one material without thinking of the consequences of how consumers and industry will replace that with alternative materials. What are the implications of that? That is in our report, and the references are there if you wish to dig deeper.
