Half the World's Orca's Could Soon Dissapear--Here's Why


Overall, in this article it explains how within the next 30-50 years, killer whales may very well face a decrease and collapse in a population caused from a toxic chemical that eventually got banned. As well as, a chemical compound that goes by the name polychlorinated biphenyls, is changing the behavior of orcas and ruining their immune systems which is negatively affecting the killer whales reproduction which researchers conclude that the orca whale itself may not survive the next few generations. In other words, killer whales are now supposedly carrying 25% more PCBs than the normal amount to fertility. In conclusion, killer whales are coming to an end or extinction if not more is being done about the problem. In addition, what I enjoyed about reading this article is the fact that I didn't know much about killer whales until reading the article which gave me a little more knowledge on the animal as well as it was something I was unaware of so it taught me some new things such as what we can do, as a ecosystem, to prevent such harmful situations.

    First reaction is just "Wow!", honestly. Second reaction is it's sad. Humans are such destructive and self centered beings. I truly hope more action is taken to prevent them from dying off. I'd hate to see them go extinct

    This is very sad and depressing. Humans view themselves as the most superior being on this planet but this is so incorrect. This is shameful and disgraceful these creatures are majestic and beautiful and deserve to be preserved.

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
