Invasive Worms

Foreign earthworms can come to the U.S. and ruin our soil, which can cause problems on that area’s food web.  Now there is evidence that invader earthworms near the Great Lakes could be stressing the region’s sugar maples. There are native earthworms in North America, but they’ve only stayed on regions where plant and humans do not live. Earthworms don’t move quick at all, it takes them like 10,000 years to make a small inroads on their own. It was interesting to learn about something that people weren't really paying attention to, but it is an important topic to discuss. It showed me that such a small insect could be causing this much damage to trees and the soil. Nobody would expect these insect to be so damaging to our environment and to sugar maples.

    This is very surprising to me as I thought worms couldn't really do much damage. It goes to show that we need to be aware of the conflicts that all organisms can cause.

    This is very interesting, because I have always thought that worms were beneficial to the soil instead of harmful. If it is only foreign earthworms that are ruining the soil, how can we tell the difference between native earthworms and foreign earthworms? And since earthworms move so slowly, how long will it take for them to really make an impact?

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
