Ecological Footprint

I scored a 5.1 I knew before I finished the test that my score wouldn't be good. The things that hurt me are my food consumption and travel, but I really don't see any alternative. My family also uses a lot of fossil fuels for travel and work. I would assume my Dad's ecological footprint would be much worse than mine, making me realize more how much change we really need. Though I question really how the numbers are constructed, it makes some sense. I know that if everyone lived like me, we would be in great environmental trouble. But I don't know what I can do but inform friends about the problem and hope for a renewable alternative fuel. Things like this scare me.......
