I have to admit that I'm not the best at being sustainable, but I sure do try.
For example, right now I'm sitting in an air conditioned airport waiting for my flight to Atlanta to start boarding. Eventually I'll be going to California, which is about 2,700 miles away. Double that because I need to come back (unfortunately). So after punching in a couple numbers into
TerraPass, I can calculate that this trip is going to produce at least 2,200lbs of CO2. WOW. That's equivalent to all the lights in my apartment running for 3 months straight, 24 hours a day.
BUT I walked and used the bus to get to the airport in the first place. AND I use energy efficient lights!
So do I still consider my efforts worthwhile?
Thats a tough question to answer, but the short end of the stick is yes. Living in America presents you with opportunities that are naturally going to make you make decisions that are more harmful for the environment. It's a combination of cheap energy and plentiful fuel-intensive activities.
If my ticket cost $2000 due to a higher environmental tax, I wouldn't have been able to afford the trip. But it doesn't, so I take advantage of the convenience.
I consider my efforts worthwhile because the small decisions towards sustainability can have more significant outcomes (atleast I'd like to think). Sure an airplane pollutes a ton, but choosing to eat locally empowers a healthier lifestyle for you and the environment for generations. Turning off the lights and the A/C for a few hours changes a behavioral mindset that says we always need everything "ON" to be happy. Riding a bike is like killing a lot of birds with one stone: exercise, sunshine, no gas and therefore no dependence on foreign oil. Although if you ride a bike in Gainesville, people will attempt to run you over.
The most important reason--of why this is all worth it--is that we are mindful. Just THINKING is saying that you care for future generations. Just being mindful of the hundreds of millions who live in extreme poverty is saying that you care that your lifestyle will not produce another burden for them to bear. For me, that is a starting point.
