Throwing a dead battery into a dump -> Battery acid gets dragged by the rain -> Polluting a river -> Flows polluting a sea -> Currents polluting all oceans.
Of course effects become smaller as scope grows, but still in many instances it's measurable, see Fukushima.
Didn't miss the point, just observing how it's an irrelevant and counterproductive distraction to the main issue. That sort of thing matters to some people.
As for the rest. I fully agree with sokoloff's reply.
That's not the question. The answer to that is Mexico, the article is about Mexico judging it and "cracking down".
The GP was clarifying the context. You refused to talk about the meat of their argument and instead opted to be pedantic about how the atmosphere diffuses.
No it doesn't matter. Where they do this is entirely beside the point. They can do it from international waters. Everyone is affected. Laws are arbitrary.
It's great that Mexico is stepping up and protect the atmosphere, which indeed impacts not just Mexico but everybody, but you're absolutely right that international waters are still a massive loophole in the laws of the world. Almost anything goes, there. Many ships still burn incredibly dirty fuel in international waters, simply because they can and it's cheaper. We really need better international regulation of these sort of commons.
I updated my post with a few questions to clarify your stance.
The point of the question is to ask whether you think this has 100% chance of not causing issues.
The next step of course would then be to say, okay if it isn't 100% safe then do you support Mexico's right to say, "hey this could cause us or the world harm, stop it".
I'm aware. But if it did cause issues it would concentrate in Mexico and dissipate globally.
But what I'm asking them is.. do they believe it's in Mexico's right to ask a person to stop experimenting on the atmosphere (global or otherwise) from their country.
It's perfectly in line with my position the whole discussion. Laws are arbitrary. Mexico is a soverign country and have the right to have whatever laws they want.
The discussion about what matters matters, even if the subject itself doesn't matter. It is perhaps the most important category of discussion. If we don't know what matters, how can we put our time to good use?
(though as another user points out this would diffuse globally, but still be concentrated locally)
