Whale Summary

Scientists have been able to look at different events in the ocean through a whale earwax. They can look at time periods and understand the correlation between certain events that have penetrated the ocean. In some cases, they found chemicals that had been outlawed many years before a specific whale was born. These tests show the lasting impact that chemicals have on the biosphere of the ocean. This method is also a lot more effective than collecting blood and poop, it is more accurate.
