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.
Salinity. Although everyone knows that seawater is salty, few know that even small variations in ocean surface salinity (i.e., concentration of dissolved salts) can have dramatic effects on the water cycle and ocean circulation.Throughout Earth's history, certain processes have served to make the ocean salty.vaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these salinity raising factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
