This past week I took a trip to the old Bethlehem Steel site in Buffalo, NY. Although the general public is prohibited from the site while remediation is going on, I was allowed to tour the site with two engineers as guides. I got the chance to see what a Superfund Site truly looks like, and spoiler alert, it wasn’t the futuristic radioactive wasteland that toxic sites are typically portrayed as by so many sci-fi movies.
Lately I’ve been pondering what type of pet I’d like to own when I finally move out of my college dorm and into the real word. During my time searching the interwebs, I discovered several exotic and even wild animals that I could easily purchase online, such as sugar gliders and even fennec foxes. After a couple minutes, I found myself stumbling on article after article that advocates against owning novelty pets. And so the moral debate begins.
It’s time to go green. After studying the environment at university for four years I have decided to practice what I preach. I have written over 60 blog posts on environmental issues, formulated a personal memoir on my life as an environmentalist, and maintained a semi-annual environmental news page. Nevertheless, I still haven’t done everything in my power to end environmental issues.
How does one actually celebrate World Water Day? It’s not like other holidays with parades, family reunions, games, or special dinners. I’ve seen lots of articles for the day that has been broadcast all over the internet, and a couple suggestions on what to do. I decided on a shorter-than-usual shower and an informative blog post. (By the way, short shower means under 8 minutes in the realm of environmental engineering as this is the average time people spend under the shower head. If 8 is more than your normal, keep doing you!)
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.
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.
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?
