It would; just look at the amount of farmland currently used to produce plants used for the production of biofuels. It's a big impact on the food production capacity of the world, and it's mainly used to mix with regular oil-based fuels so that the oil/gas companies adhere to government standards, tax reductions and customer goodwill, whilst the biofuel producers get government grants and fundings and more tax deductions.
Of course, that's (iirc) first-generation biofuel, second/third generation (or grade) biofuel uses biowaste (shells, green stuff, animal waste, stuff that would otherwise be processed into compost or fertilizer).
Most biomass generation occurs at plants that have other operations involving wood, so even much of the wood burned is byproduct.
