Interesting Segment from NPR’s TED Radio Hour

If you haven’t heard of it before, I think NPR does a really nice job putting together their podcast, TED Radio Hour.  As the title suggests, it’s a selection of related TED talks, but also mixes-in interviews with each of the featured speakers. The show translates well to an audio podcast but the video for each talk is easily accessible from the NPR website.

The episode from last week was titled, Everything is Connectedwhere the theme was based on “…how everything in nature is connected, and how we can restore its delicate balance.”  If you only had time to listen one segment, I would suggest, What Listening To Nature Teaches Us About Changing Habitats.   The segment features Bernie Krause, who has been recording the sounds of nature for over 45 years.  From the NPR link:

Bernie Krause is a bioacoustician whose recordings have uncovered nature’s rich sonic tapestry — along with some unexpected results. Krause captures the fading voices of nature, studying sonic interplay between species as they attract mates, hunt prey and sound out their roles in the ecosystem. His documentation of vanishing aural habitats is a chilling reminder of shrinking biodiversity.

Climate Change

I came across this article that I thought was pretty interesting. U.S. Secretary of State John Kerry talks about home important climate change is and the necessary actions that need to be taken in order to improve the atmosphere’s conditions.

The world taking care of itself

This link is about a bacteria found in the ocean that eats plastic which is the reason the quantity of debris has remained level according to the article. Scientist have begun to research whether this bacteria does good or just recycles the plastic toxins up the food chain.

Renewable energy has environmental impacts too

A biologist friend sent me this link about birds getting scorched at a new concentrated solar plant in the desert along the CA/NV border.

While the numbers of birds killed is probably much lower than the number that are killed by domestic cats and windows, ecologists look at what species are being killed in the context of their overall populations. If your cat kills 10 starlings or English sparrows this has much less ecological impact that if a wind farm kills 10 golden eagles.

Changing Your Perspective on Last Night’s Dinner: Quinoa

Quinoa, a nutritious grain-like food, has been in high demand over the past few years. This article addresses some concerns about the regions where quinoa is grown and how it is affecting their culture and sustenance. Can Americans and Europeans figure out a way to strike a balance, or will the Bolivians continue looking elsewhere for affordable food?

(Although this article was written three years ago, it still applies today because quinoa was served at dinner tonight, and at almost every meal)

Tokwe-Mukosi Dam failure in Zimbabwe

Tokwe-Mukosi-01

 

This crisis is still unfolding. The dam was constructed to combat drought-related water shortages. Flooding caused by recent heavy rains has seriously damaged the partially constructed dam. Families are being evacuated and there is a chance that the dam will completely fail. This illustrates that there are risks associated with engineering solutions to manage scarce resources.

“a picture is worth 1,000 words”

http://www.history.com/topics/water-and-air-pollution

I came across this link while writing an essay response to one of the questions on my first assignment for Prof. Nicodemus’ class, EGRS 352: Energy Technology and the Modern World. However, I’d like to share this with VAST 203. The photo I came across that website shows a lake full of pollution. It appears that almost all the garbage on the lake are recyclable materials. In my opinion, people should volunteer to not only pick up those bottles, aluminum, etc. but also take them to the recycling center to be recycled.

Concerns about SUVs

Here in the United States, we rely on cars to get around. Some of us, including me, drives a large SUV that only averages about 13 miles per gallon. While I enjoy driving an Escalade, I do have some concerns. I sometimes have a guilty feeling when I find myself driving alone (without any passengers and cargo). Since the Escalade is a nice car, I do get positive attention from friends. I also noticed that a large number of Lafayette ski team members drives SUVs, including a few Suburbans.

Since the US (especially outside the Northeast) do not have great public transportation system like Europe and East Asia, we have no choice but to drive. Some of us must drive SUVs due to carrying a lot of cargo or even due to having large families. Whether their SUV is for personal use or business, households prefer to keep the number of cars to a minimum to minimize costs of owning cars. Therefore, this leads people to drive their SUV alone. I do know someone who sold their SUV and switched to a sedan due to costs; I personally pay $80 to fill up my Escalade.

Petroleum is running out at a fast pace, unfortunately. While the gas mileage of cars have improved over the past few decades, the great news is that SUVs are being included too. I have seen an advertisement for a Hybrid Escalade, running on roughly 20MPG.

Snow Geese

As promised, here are a few pics of snow geese, all from within 10 miles of campus. The first shows several flocks passing high over my barn when I got home yesterday. Click for larger image.

Trash mountain

https://www.google.com/search?q=trash+mountain&tbm=isch&tbo=u&source=univ&sa=X&ei=gxf5UtGDOKrlyQGRuoGAAw&ved=0CD4QsAQ&biw=1279&bih=636#facrc=0%3Btrash%20mountain%20ocean&imgdii=_&imgrc=_

 

YUCK…the above link is the Google Images result of Trash Mountain, which shows a consequence of garbage dumping. Not only that it is harmful to the natural environment and hurting especially the oceans, it also ruins the beautiful landscape.

Opinion on high gas prices

We all have been here. We are complaining about gas prices these days. I can still remember when, as recent as a decade ago, the gas prices were between $1.00 and $2.00 per gallon. Now we pay around $3.00-3.50  a gallon in the northeast. I drive an SUV and it costs me $80 to fill up my gas tank. However, I think the gas prices are relatively low. In spring 2012, I took “VAST 270: Energy Resources and Tech” taught by Prof. Hornfeck (yes, VAST 203 is my second VAST course) and I can recall Prof. Hornfeck saying that our gas prices are actually low, considering the high demand for gas resulting in a major shortage. I believe that higher gas prices would deter larger number of people from continuously getting gas and get them to use a more efficient form of transportation (public transportation, bicycle, walk…). In Europe, while public transportation system is very good, the fuel prices are expensive. € 1.50 per liter, which is equivalent to $7.75 per gallon.
