Yes, after a few hours being cooped up inside an aluminum alloy tube ingesting recycled air, airplane food is the last thing you need. But next time you plan on leaving your breakfast (featuring the infamous green eggs and ham) untouched, consider the following...
Recycling aluminum cans is one of the easiest things to do (and best for our environment), but did you know every time your plane lands in Toronto Pearson Airport, none of the pop cans you consumed on the flight gets recycled? (so does all the other recyclable garbage) This is due to possible probability of cross-contamination of disease-carrying agent from one country to another.
If you ever travel on a Canadian air carrier and spot a flight attendant with "pro-environment" buttons on her suitcase+apron, and that she leaves the aircraft carrying a bag of plastic bottles, and that she "forces" passengers to reuse plastic cups/bottles during a flight and asks people to take off their own plastic waste for recycling.... yep thats me.
I am a visual arts/industrial design student and I also work as a flight attendant for a Canadian Airline. After 3+ years in the industry, I have decided to either make a commitment to change something or quit this environmentally-devastating job.
