Hi everyone, my name is Mariana Shenouda , I live in cairo, Egypt. I didn’t think about the CO2 footprint until we did this survey. I was surprised to know that I’m above the average but I learned that if everyone tried to decrease his footprint I think everything will change . I tried to decrease mine especially in the transportation ,like if the way is not long I can walk instead of using transportation that effect our global warming. We have to try to care more so we can really make a difference, like we can decrease using electricity with shutting down the computer if we are not using it and turn off the lights when the sun still shine . I think everyone has to start to care more to make big difference.
