I was thinking about CO2

[Churchill]

If the government are going to tax us on the amount of CO2 we produce, they should give a rebate for any CO2 offsetting we might pay for.

What you are assuming is that CO2 is a real environmental problem and not an excuse to raise revenue!

They get a lot of forest fires in the rain forests.

Creating a new rain forest while they are busy chopping down others to make room for agriculture doesn't make a lot of sense. It would probably make more sense to grow rapidly growing plants or coppice and burn that instead of coal. Still not viable though. Too many people.
