You guys do know that without fossil fuels emitting carbon dioxide into the environment you wouldn't be able to cut and burn your inferior wood right? Quit living in the 1800's hippies, it's time to burn gas and get with the times.
I think you are a flaming idiot, I know you are a troll, but I am going to respond anyway.
At what point prior to about 500 years ago was the burning of fossil fuels commonplace? Nobody was mining coal, drilling for oil, burning natural gas, or had even thought about petroleum derivatives such as propane or diesel. So if nobody was using what you appear to define as fossil fuels, then we must not have had any trees on this planet prior to the 'discovery' and common use of 'fossil fuels'. Additionally - I think you have carbon MONoxide and carbon DIoxide mixed up. And both have been a substantial part of the atmosphere since the dawn of time - volcanoes and forest fires come to mind.
And when we're all run out of oil reserves and natural gas and coal, we will be back to burning wood, and maybe by that time we'll have found something clean and affordable to replace it all anyway - solar, wind, hydro or even fusion.
