Europeans don't like the working conditions of shipbreakers in India, and don't like the pollution it creates in India. Europeans can't directly tell the Indians what they can and cannot do.
Instead, the parent post is proposing to use the state surveillance app aratus to go after and prosecute the f** out of people that sell ships to India.
I said it seems like a lot of work to try to stop someone in another country from doing something in their own country.
I prefer the more hands off approach where you let people in other countries decide what they want to do as long as they aren't hurting you. If India wants to ban ship breaking or impose harsh restrictions, they can do that themselves. I think it's arrogant and dehumanizing for Outsiders to try to control what happens in India.
I don't disagree on the overall principle of avoiding the establishment of de-facto extraterritoriality, but it should be said that environmental pollution is not a localized problem. The Earth is a connected system, and what happens in India or China will eventually affect Europe and America (in the form of polluted air/water making its way here, or climate change provoked by emissions), and viceversa.
Environmental issues are inevitably global, and countries should talk about them and find global agreements that are fair and enforced by everyone. We can't just hide behind "my backyard, my rules".
Yes. What you are describing is very similar to people always asking for federal laws, when states or counties could handle problems as well. Out of a fear that those savages down in state X could vote for the 'wrong' policy.
They're regulating the behavior of their citizens in their domain to prevent them from doing actions that will lead to detrimental outcomes for their citizens.
