This is a nice bit of satire.
Of course, this highly dangerous substance is better known as "water."
1. Should the EPA step in and do something about Dihydrogen monoxide?Obviously the point here is to compare water with carbon dioxide. Both are natural substances, both are required for life on Earth, both are safe under normal circumstances, and so on.
I would suggest that the EPA would only be involved in controlling the amount of water in the environment if it were somehow changing in a way which could have negative consequences. This seems extremely unlikely. However, in some kind of science fiction scenario where the level of water in the atmosphere went greatly up or greatly down, it might be appropriate.
There
is evidence that the level of carbon dioxide in the atmosphere is going up sharply. The big debate, of course, is what effect this will have on the environment. I'm not going to get into the debate over global warming, but I think it is very evident that such a rise in carbon dioxide must have
some effect on the plant life on this planet. Maybe good (higher crop yields) and maybe not good (higher pollen levels) and most likely a mixture of both. In any case, it's a good idea to
monitor such levels.
Link2. Why is there so little press on Dihydrogen monoxide?Because there is no evidence that I know about that the level of water is rising or falling in the environment. There are, of course, reports on local changes in water; desertification and flooding, for example. If there
were a major change in the amount of water on this planet, that would get a
lot of press.
In any case, thanks for the laughs.
