What is biomass?
The main cons of biomass lie in how it's used. It does come with environmental risks; The Union of Concerned Scientists explains that biomass produced for energy can potentially be harvested at unsustainable rates, cause damage to ecosystems, produce harmful air pollution, consume large amounts of water and produce net greenhouse gas emissions. However, these risks are mitigated when biomass is managed properly. Energy crops should never compete with food crops for land, and emissions of biomass carbon should be taken up or recycled by subsequent plant growth.
