I reckon they'll have to clean themselves over the next few million years. They're after finding plastic deposits at over 2 miles of depth off the Kerry coast recently. Fuck knows how you'd clean that up without doing more harm than good. Same goes for the Fukushima Pacific leak. The most important thing is to stop adding to the damage. Another big thing is bees, they're vital and being killed off rapidly. I've seen one in the last two summers where I used to see hundreds. All you see now are wasps. Far too many insect species being killed off and it puts the entire ecosphere at risk.
