Why are cane toads are a problem?

Cane toads in Australia have been having bad impacts on the environment surrounding them. They do not have really any predators, so their population has been increasing very quickly. Any species who tries to consume them end up being harmed and or killed due to the poison that they release. This is causing a decline in many species and could lead to extinction. Scientists are trying to find ways to reduce and control their population size, but as of now, they are negatively impacting the environment which is leading to a bad outcome in the future.

    This article relates really well with the video we just watched, so fascinating! It's a shame that the species who try to consume them end up being harmed.

    This is interesting to see the downside of a purposely introduced species. The cane toads sticking around are now dominate in the environment but killing the previous species. Is it better to keep them or should we take them back to where they came from?

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
