What Do Ducks Hear? And Why Do We Care?

Aubrey Trout

It is hard to understand ducks and hard to tell if they can hear underwater. When ducks dive into water for fish they often get caught in fishing nets, over 40,000 ducks die a year. Over the years there has been a tactic of trying to send pings that send warning like they do with other mammals, but first we need to know if it works. So Ms, McGrew is doing some experimenting trying to do some hearing test with animals, like giving them treats when they react to sound. Then the ducks learned how to peck certain targets when they heard a noise underwater. All the ducks react different but studies say they can hear under the water about three kilohertz.

    Hopefully we can save a large population of ducks from dying each year with the use of these pings. It's interesting to learn how many ducks die a year because they aren't talked about much.

    Why has no one thought of this question? It's interesting how McGrew approached this experiment.

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
