fastest pace of any time in the past 300 million years,
even more rapidly than during a monster emission of planet-warming carbon 56 million years ago, scientists said on Thursday.
Oceans get more acidic when more carbon gets into the atmosphere.
Human activities, including the burning of fossil fuels, have increased the level of atmospheric
carbon to 392 parts per million from about 280 parts per million at the start of the industrial revolution. Carbon dioxide is one of several heat-trapping gases that contribute to global warming.
The U.N. Intergovernmental Panel on Climate Change projects world temperatures could rise
by 3.2 to 7 degrees F this century."

very problematic, and are killing hundreds of species in the oceans.

Trees are a good idea, but not enough.
As a practical matter we can't plant enough trees to offset our fossil fuel use.
Try a carbon calculator like the one here: http://www.carbonify...-calculator.htm
How many trees do you get?
Now imagine trying to plant enough trees to offset the US's use of fossil fuels.
Can't just plant them, got to keep them growing. If the tree dies and decays or burns, then the CO2 that was sequestered in the tree's biomass goes right back into the atmosphere.

But we could at least try, right? Maybe I have understated the fossil fuel consumption. :) I'm not saying that it is the total package to save the environment.
