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. According to numerous scientific studies, fish, shellfish, and other important species are declining in many places.
A recent study which has mapped the total human impact on the seas for the first time has revealed that the picture is far worse than the scientists imagined. 40% of the world's oceans have been heavily affected by human activities, including fishing, coastal development and pollution from shipping.
