Under-reported global environmental problems

1. Ocean acidification. I've been hearing about how excess carbon dioxide is changing the PH balance in the oceans for about a year, we'll see how serious the effects will be.

2. Global nitrogen overload: we're now adding more biologically-available nitrogen fertilizer to the planet's ecosystems than all the naturally processes do, combined. Look forward to a planet of weeds and algae - that's the direction we're heading.
