Easy for you to say if you are not paying $10k for the removal of a lot of large trees. Just like you won't be paying for the increased costs to cool my home in the summer now that I no longer have the natural and free cooling effect of shade on my house. Removing trees is not without consequences and like my example, the benefit of doing so from one season is often offset by the loss of that benefit from the opposite season.

And as a sales rep, by definition everything you say is likely not exactly true or accurate. Just get the signature on the contract is likely your boss's motto.
