and whilst planting trees may not be the most effective thing

so I wouldn't say its a bad thing.

Two important parts of my post AP. I wasn't aruging that planting trees to combat CO2 is a good idea (although they take in small amounts) I was arguing that planting trees is a bad thing, thier pretty, do some small work towards converting CO2 to O, and are a good supply of wood....

But I do agree as a strategy for stopping global warming not great...

I wouldn't want something to drastic done about global warming as you said we could go to far the other way (or just mess up something else) I would rather we reduced (or somewhat nuetralised) our effect. Only if we are in serious trouble should we go to dratic measures (if were dead if we dont) otherwise we could just makes things worse...
