You have got it backwards. These trees were not felled by individuals who were toiling to make a better tomorrow. On the contrary, greedy industralist made them toil and die for their profit. When Queen Victoria and her chronies were filling their pockets by looting the world, London was still a slum. Henry Mayhew documented this in his publication London Labour and the London Poor[1].

Things like 8 hour work week, health benefits etc were achived in blood.
