Oh yeah?

I live next to you and drill 2,000 feet down and start pulling up oil. What is the extent of that oil reserve relative to my land?

I pull water from an aquifer accessed from my land, which is next to yours.

I go out onto the deep blue sea and fish.

A river runs through my backyard and yours, and I fish that river.

The short term profit derived from cutting down the rain forest on my property which is next to yours allows me to live a great life, since I have nobody to pass on my inheritance to. However, the act of cutting down that rain forest has created edge effects at our common property line, which has a deleterious effect on the ecosystem of your property.
