Fish Flingers Make Trees Grow Fast

In Hansen Creek, ecologist Thomas Quinn and students from the University of Washington studied and monitored salmon populations. Whenever they found dead salmon, they would throw the carcasses to the riverbank. However, after doing this for 20 years, Quinn and the students discovered that the forest on the side of their fish carcasses was growing faster than the opposite bank. They measured tree trunk diameters and nitrogen isotopes in white pine needles, and counted tree rings. They discovered that the nitrogen in the needles came from marine sources, proving their theory. If we used fish carcasses as growth enhancers, we could probably decrease the time it takes for some plants to grow.

    So weird! I wonder if it's possible that there were other factors involved.

    This could be beneficial if farmers ever have a shortened growing season due to climate change.

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
