i have recently learnt that to make biofuels, the government has allowed producers to dig up peat bogs in britain. there are few peat bogs left in britain after it was widely used as a fuel and they are habitats for several endangered species. since biofuels harm the environment just as much as regular fuels, it makes it harder to find a green fuel. although there is the possibility of hydrogen powered cars, not many car producers are striving to produce cars that run on hydrogen.
