Great Barrier Reef experiencing third major bleaching treatment

The Great Barrier Reef is experiencing its most widespread bleaching treatments due to warm temperatures and warming oceans are threatening the corals. The Great Barrier Reef along with its surrounding areas are facing periods of heat stress in which is causing the third major bleaching in the past five years due to climate change. This is bothersome because coral does not have time to recover and grow back since the destructive events are occurring more frequently than scientists were expecting. Coral bleaching is a response to abnormal conditions that causes corals to expel tiny algae that live in their tissues to become white leaves the corals more susceptible to diseases. The corals are an important part of the ocean ecosystem because it is home to a diverse array of marine life and the bleaching is starting to have an impact on the biodiversity of the ecosystem. Climate change is having a huge impact on ecosystems and actions need to be taken to stop these destructive events from occurring before they cannot be reversed back to normal.

    I did my same blog post on this article and I found just as concerning and worrisome. The Great Barrier Reef is one of the oldest reefs and result of it being bleached is highly concerning. It has been a home to a vast amount of marine life and has provided food to many. Reefs also protect our shoreline from waves, storms, and floods. This meaning that marine life is not the only thing being impacted. Climate change is something that unfortunately cannot be resolved overnight, but maybe with more research, there could be a way to lessen the effects.

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
