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.
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!)
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. You can read more about fish and their capabilities to clean water online. Here is the link to a discussion forum for this topic.
