Light Pollution Affects Cougars & Mule Deer

 Francine Parks

10-26-20

        A recently done study showed that mule deer in light-polluted areas become more active during both day and night, than mule deer who are not in these areas. It also showed that their predator, cougars, are still able to hunt the mule deer in light polluted areas, which they do by observing the darkest spots and recognizing it as their prey. Since artificial light is typically found near homes or in settled areas, both cougars and mule deer are now found closer to those types of settings, while still maintaining their predator-prey relationship.

        I think that while it is good that the natural relationship between the cougars and mule deer still exists, artificial light is overall not a great addition to the environment. Mule deer, cougars, and all other animals are safer and more suited to living in areas with natural light and similarly natural conditions. When wild animals start to come closer to populated areas, it increases their chance of getting hit by a car or having contact with human-made pollution, which is damaging both to them and to their habitat.

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
