Haha fuck earth day, planting a tree won't make up for all the lights and computers left on at the place I work at (with over 8000 people at the complex).
Nor will it make up for all the 2nd world countries pumping out all their industrialization. Nor will it make up for all the other corporations and countries polluting the hell out of the Earth.
The Earth cannot sustain humans in the way that we are going. The Earth will be just fine, humans are fucked though.
