Let’s test that. All the Greens and liberals (but I repeat myself) should save the Earth by committing suicide. We’ll make ‘em a nice memorial, we promise!
But that poses many problems in itself:
Methodology - Guns are out, as are plastic bags, drowning would waste water. I guess that would leave hanging, but; cotton or manila?
Disposal - Cremation is obviously out, as is burial at sea. We could just put them all in Greenland, but hell, that place is melting. Soylent Green to recycle?
