Ecological Footprint Re-calculation

When I first took the Ecological Footprint quiz, I was shocked my score was 1.5 Earths. Sure I recycled and composted everything and had pretty good habits like unplugging all the wires from the outlets when I wasn’t using them, it still seemed high. Especially since I had terrible eating habits. I ate a lot of processed food and anything fresh, such as fruits and vegetables, was not local or organic. So, when I retook the EF quiz and received 1.8 it felt right. I think I must have messed up some calculations the first time to score as low as I did. My true EF score at the beginning of the quarter had to be over 2 Earths easily.

I am very pleased that I followed all my goals to reduce my EF–I’m assuming it did indeed decrease because I can guarantee my habits are a lot more greener now than they were at the beginning of the quarter. I didn’t meet my goal of 1 Earth, which I knew was farfetched but it was still worth a try. The biggest impact I think came from the Food category. I used to eat poultry products every single day and I successfully reduced that down to 2-3 times a week. During the past two weeks alone I only took the bus three times. I used to ride the bus at least two times every day to and from class. I kept carpooling and decreased the amount of time I spent in the shower to around 12 minutes (except when I wash my hair, then it’s not feasible). I’m also buying more organic and not eating as much processed food as I usually have which is not only good for the planet but me too. As I have stuck to my goals the entire quarter, I think it’s safe to say I won’t be reverting to bad habits as easily I’d feared I would.

Article 10: Power Pulls Drinking Water from Desert Air

Moisture Evaporator (left) from “Star Wars”

The second I read this article I became intrigued and thought how futuristic and sci-fi it sounded. In the article, it actually referenced Star Wars. The idea is to suck the humidity out of desert air and turn it into drinkable water. How it works it that you have a powder-filled box within another box and it’s left open in the night and when you close it in the morning, it helps heat and water vapor become trapped inside. The water condenses and trickles down the side. There are limitations though as this method only results in three ounces of water a day.

“The water goes in and the first ones go in and make the pores more polar and so more water comes in.” –Omar Yaghi, U.C. Berkeley chemist

Water is the most valuable commodity on Earth yet it is not treat at it’s true worth. Water scarcity is a huge issue and some places in the U.S., such as California, it’s already gotten so bad that they’re passing water restricting laws. As desperation and the eminent threat of lack of drinking water grows, I’m curious to see what kinds of solutions and innovative ideas begin to rise.

Article 9: 5 Ways for Businesses to Cut Down on Their Plastic Waste

About a month ago, I read an article on CNBC talking about scientists who had, accidentally, created an enzyme that would help make breaking plastic (PET) down easier. Plastic is a hot topic right now and something everyone who cares about sustainability is obsessed with, trying to figure out the best solution or method for dealing with this persistent material that just refuses to die. This article outlined some ways of dealing with it.

Five Ways of Cutting Down on Plastic

  • Reduce, Reuse, Recycle: An oldie but a goodie. Don’t use plastic when you can avoid it, reuse it, in packaging for example, and recycle
  • Think Through the Consequences: Consider what happens to products at the end of their lifecycle and integrate that into the design (as Ottman called it: Build In, Not Bolted On)
  • Talk to the Waste Industry: Before you go building something, make sure there’s a waste contractor who can deal with it
  • Don’t Forget the Polar Bears: You don’t want a polar bear to be homeless because your product contributed to climate change and melted her home, do you?
  • Shift the Economics: Once it’s in their best monetary interest to be greener, consumers will develop sustainable habits
