Confused mayflies wreak havoc on a Pennsylvania bridge

Mayflies came back to the Susquehanna River after efforts were made to remove pollution, however, they are becoming a problem. Lights on the bridge over the river attract the mayflies by mimicking moonlight on the rivers surface, and they die on the overpass; sometimes the numbers are enough to result in knee-deep piles. The bridge is planning to be renovated to guide these insects back to the river rather than to the lights.

 I think this is a great example of how human activity can disrupt the natural cycles of organisms. The bridge not only causes problems for humans, but also for the mayflies who are trying to reproduce, and must be renovated to cater to both.

    I think its crazy how much humans can affect the natural order of things and causing animals to act differently than they normally would.

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
