These steps only 'reduce' carbon footprint; they don't relieve us of our responsibility - that is, if we are complacent in other aspects or if we are apathetic to the exploitation of environment and people by big corporations and by people in our very neighborhoods. The steps in this video can only be a starting point. (See "Story of Stuff" and "The Corporation" on this site) ----- On a different note, on the use of tap water, obviously the suggestion in the clip applies only to some countries - mostly in the west. But over in those countries too, it is recommended to use effective filters: Pharmaceuticals - like antibiotics, mood stabilizers, and sex hormones - have been found in drinking water supplies in America. See here http://hosted.ap.org/specials/interactives/pharmawater_site/day1_01.html ----- The last point about factory farming of cattle and greenhouse effect in the clip relates to the issue of excessive meat consumption. The more the demand for meat, the more grain would be fed to cattle, instead of humans. It takes about 7 gm of grain to produce 1 gm of meat protein. About 40% of world grain is fed to animals, whereas you have more than 1 billion people in the world who, as per UN estimates, sleep undernourished or hungry each day. On world grain consumption see http://www.news.cornell.edu/releases/aug97/livestock.hrs.html ---- on world hunger stats see http://www.wfp.org/hunger/stats ------- On top of that, there is environmental degradation (excessive emission of 'methane') that the clip refers to. According to one analysis food 'production' process is more environmentally costly than food 'transportation', and if average Americans replace only 1/7 of their meat consumption with vegetables, it can minimize environmental cost equivalent to that which can be obtained through maximum localization (eating local). See more about that study at: http://www.ethicurean.com/2008/06/23/food-miles-vs-food-choices/ ----- Some people want to make it an argument about "food miles vs. food choices". I think we can incorporate all of these good ideas into our lifestyle - as we encourage eating local and organic (wherever it's realistically possible), we should also encourage cutting down on meat consumption.
