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.
Often times, other species can also invade an ecosystem and do harm to it by interrupting the life cycles of other organisms, causing a clash of nature that has already been damaged by the overflow of pollution. 5. Ocean Mining: Ocean mining in the deep sea is yet another source of ocean pollution. Ocean mining sites drilling for silver, gold, copper, cobalt and zinc create sulfide deposits up to three and a half thousand meters down in to the ocean.
