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. Continue reading “Guilty Confessions”
Recently I’ve been working on a project at my job – How much energy could we save if we changed our building’s roof to a green roof? Answer: I don’t know. That would require a lot of math which I don’t have the energy to calculate. But I did learn some stuff on the way to giving up. For instance: Changing up your roof adds oxygen to the air and attracts wildlife. Continue reading “Green Roofs”
When I visited the famed underground cistern of Istanbul, which once provided a constant water supply for a massive palace, I noted that fish swam around in the water to “reduce bacteria”. Of course we’ve all owned algae eating fish at one point or another that kept our goldfish tanks clean, but these were massive fish that took the form of catfish or maybe even koi. After much wonderment I had the chance to look further into this method of decontamination myself. It turns out that even scientists debate the effectiveness of using fish to clean water. With a little reading I discovered that fish might consume algae in reservoirs in developing countries, but they certainly don’t purify water enough to drink it. Fish catalyze a reaction that reduces ammonia from rain water, making the water more suitable for life but not quite drinkable. Frankly, it sounds like an experiment I’d really love to try.
Lima, Peru is said to have nearly one hundred percent humidity. That means that this major city located in a desert with less than one inch of rain per year has air that is completely saturated on the most humid days. Still, over 18 percent of the Peruvian population lacks safe water, and around 32 percent are not equipped with modern day sanitation.
Using inverse osmosis filtration and electricity, the University of Engineering and Tech of Peru developed a billboard that filters, condenses, and cleans water from air. The billboard can produce almost 100L of clean water per day. I hope that soon all billboards in Peru have this feature, and that the plans for building and modeling similar products are released!
