> It turns out that oxybenzone can be toxic to baby coral at levels as low as 62 parts per trillion. In plain English, that's equivalent to one drop in 6.5 Olympic swimming pools. Dr C. Downs surveyed reefs in Hawaii and the US Virgin Islands. His team measured levels as high as 1,400,000 parts per trillion. That's more that 20,000 times higher than the toxic levels.

In the case of cosmetics there are many ingredients that should just be illegal, whereas in the case of air pollution it's an issue of goods and services that should be legal, but where the total levels of various pollutants aren't currently capped and then priced accordingly.
In my case this was our honeymoon, so we would have gladly (or at least begrudgingly) paid an extra couple hundred bucks or whatever. Whereas someone else just wanting to go to some conference might instead choose to participate remotely.
Sorry, didn't mean to pick on you. I just get frustrated when people saw anything remotely "save the planet" and then tell me about their massively polutting air travel to distance lands.
