I have tried many times without success to find out who is supplying Costco with it's gasoline. In our area it is delivered by an independant fuel delivery service so unless you followed the truck you would not know where it is comming and going to. The supplier could also change from time to time based on bidding.
Oceans around the world are becoming degraded. Evidence shows that human activities, including intense fishing around the world, are altering ocean ecosystems beyond their natural state.

Bass appear to have two effects on bluegill. First, bass simply eat a lot of sunfish helps control their numbers. Second, bass force small, vulnerable sunfish into thick weeds; but the big sunfish -- too large to be eaten by the bass -- are free to forage wherever food is most plentiful. So the presence of bass reduces the competition between small sunfish and large, thus allowing the large sunfish to grow even larger and faster.
