First Vertebrates On Earth Arose In Shallow Coastal Waters



Roughly 480 million years ago, fish, the first vertebrates as well as our earliest back boned ancestors, arose in shallow coastal waters. It took scientists a long time to figure out what type of water and the depth of the water that fish arose in due to the tiny fossil records. From thorough experiments and research, it was discovered that fish remained in the shallow waters for about 100 million years in order to evolve and adapt to different environments before they occupy different areas of the ocean. I find this article fascinating due to the idea that the deep parts of the ocean were once cleared of all types of fish. Other than offering interesting facts, this article also gives added insight on the evolution of living organisms on planet Earth.

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
