Desert Island

If you’re ever stuck on a desert island and have the chance to bring three things, don’t fret about potable water. Save your three wishes for a designer bikini, Netflix, or something more worth your while. According to Water Conditioning & Purification Magazine, activated carbon from coconut hull is a more efficient filter than activated carbon from bituminous coal. Below is a picture featuring this week’s topic of coconuts, and holding the coconut is a wonderful French traveler, writer, and inspirer I follow on Instagram, Jade Phoenix.

Grad School Purgatory

Since urban dictionary doesn’t quite spell it out for you, I will: This is when applications have been completed and sent, but there is neither an acceptance nor rejection from anyone. There is little to no knowledge of when an answer will arrive, if ever. This is grad school purgatory.

Blowing Bubbles

Did you know that bubbles can clean water? Specifically, dissolved air flotation (DAF) and ultrasound are two methods of making water safer with bubbles. DAF can be used to replace sedimentation in municipal drinking water treatment. Large particles are typically settled out using gravity, but with DAF, bubbles are produced by an oxygen tank pumping air into the bottom of a basin and small particles attach to the sides of the bubbles. The bubbles rise to the top of the basin and the particles are swept off the surface of the water by a skimmer.

Passive Acoustic Monitoring

The following article deviates from my conventional posts about homemade water treatment, but it is an important issue in the environmental realm- and could give scientists a clearer picture of endangered species.

“Within the field of cetacean research, a passive acoustic monitoring (PAM) system can be defined as a set of acoustic and electronic devices aimed at detecting and tracking marine mammals by listening to their vocalizations” – Brunoldi, et. al.

Greenwashing

All Natural. Organic. Eco-friendly. Green. Farm Fresh. These are the sexy buzzwords that draw us in to products that unscrupulously exploit our desire to go green. The FDA doesn’t regulate these terms, and they are often nothing more than just words. “Green” products contain the color green on the packaging. “Farm fresh” covers essentially any meat or dairy product. “Natural” is more of a sentiment than a descriptor. And just to give you a sense of the word “organic”, Dichloromethane is an organic compound and is toxic. I definitely wouldn’t want that in my salad. So then, how should caring consumers discern the environmentally-sound eggs from the chemical-ridden cosmetics?

Storms

Exhibit A: Picture of a microburst.

I was standing in front of the window of our small apartment. I could barely see it at my height. Perhaps it is one of my first memories. The sky was a purple and pink hue. It looked so pretty but Mom said there was a storm. You shouldn’t stand near a window in a storm. Continue reading “Storms”

Guilty Confessions

Microbeads are banned in some states.

Environmentalists like to act high and mighty sometimes, like earth goddesses destined to restore the ecosystem and punish those who harm it. Labor Day Weekend I was feeling determined. I ran two miles to watch Suicide Squad at the theater, and ran back. How environmentally conscious, right? I know I seem perfect, but I have some confessions to make.
