Eco Footprint in Cottage Living

I guess playing just 1 simday won't do much harm permanently, because you will affect the environment in a more steady direction over time. Playing other houses within the hood might help, too. Unless you rebuilt the cottage and used mostly bad stuff? In my game Bramblewood and Henford both became very green immediately, but then I play most lots and thy all do rather environment friendly stuff. They all have fireplaces though, which is bad, but growin g plants etc might make up for it.
