Sounds fairly reasonable, if you cause the deaths of dozens if not hundreds by negligently or maliciously polluting the atmosphere then so be it.
Hopefully they will be bringing it back here as well for the likes of child and young people killers to name just a couple of categories.
Thing is I can understand genuine accidents, a tanker crossing a bridge and get's into a accident leaks and spill's. It wasn't intentionally dumped but the big companies like Foxcon who don't even give the workers gloves who handle thousands of toxic components a day and end up dieing at 30 years old through a industiral sickness. The should address that (as should the companys who contract the fab shops), and underage labour, it's not a kid working in a shop at the weekend or after school it's 10 year old and up assembling crap we take for granted on a daily basis, who end up sick because they have been working with chemicals or fumes that are highly toxic.
Start with that, then expand into whole environment protection meathods.
What is needed though, is a massive shift in our attitude to ewaist. One of the indians who I met at my last job prior to out souring. Told me of a town just up the road from him, who's sole product is copper not from mining but burning used cable and electrical products. The job employs young kid's like 4- 9 they pile it up, set it on fire and when it's burned out the pay the kid's to "Find the shiney" and the kids that find the most get the biggest pile of pennies, the kids that survive to adult hood become the ones who run the burn pits and pay the kids, it's a vicious cycle. That most of us could stop if we demanded recycling was done here inside the EU, we can process more and put the material back into circulation faster than any place in the 3rd world.
