Instead of just saying you care, DO SOMETHING ABOUT IT! Words don't matter Actions do! Half of you probably only say you care but don't do anything about it.
You make an excellent point. Unfortunately, individuals can enact only a miniscule affect. National governments also currently have relatively little clout in a neo-liberalist era. The IMF, World Bank, and other significant players (such as McDonald's, Starbucks, Symantec, etc.) have the infrastructure and the funding to make large-scale production sustainable, should they care to do so. And the general public has very little persuasion over these giants' decisions. What we can do is purchase products and services from corporations with proven track records of sustainable operations, so that we give them further money to invest in further sustainable operations. Because changing the current production line is an overwhelmingly expensive undertaking.
