Warming Temperatures May Cause Birds To Shrink

In Australia and New Zealand, data was collected at 30 locations, collecting the measurements of 40 sparrows at each place. Their findings supported the idea that increasing summer temperatures lead to a smaller average adult size which could affect birds' fitness further down the line. By studying these birds, it helps the scientists to understand how they adapt to the changing climate. I think this can shed more of a light and make more people begin to research the effects temperature variation has on development. I never thought about the bodies of animals being different sizes on depending where they lived and the temperatures there. (cold temperatures= larger bodies, hot temperatures=smaller bodies)

    I love the connection between environmental change and evolution. I'm going to use this example in my biology class!

    This is an interesting article. It seems like the decrease in size could be an evolution because of the change in climate. However, it is definitely not a good change since, like you said, it will affect the birds' fitness.

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
