I personally think that we can't really change anything without a change in mindset. This includes education as well. Changing one thing is great, but we do have to treat the underlying symptoms of a problem. The best thing humans can do is read up and be conscious and aware of what we are doing, as well as being willing to see other people as just that, people. Once that happens, we can go on to reduce our water usage, reduse our carbon footprint and other such things.
