I get the density argument. But trees are important too...no matter how close to a subway station they are.
Since I am not advocating to preserve any the buildings here...as I am suspect folks living here are walking off with a good wallop of retirement money after conceding their homes to the developer (assuming how that works). But it would put me at ease if the developer preserve as much trees as possible and where possible.
....that's probably not the answer you where looking for. But it's the best I can do in defending my emotional response to this. Sorry.
