Many people in Germany said, after the second world war, that they never knew what was going on in the concentration camps. They never knew what was going on in eastern Europe. They never knew of any horrors.
Today many people don’t know that we are ruining our planet. (How is this possible?) They don’t know about the man made climate change and what deforestation leads to. They don’t know where the nuclear waste, toxic waste and insecticides end up. They say. “There are so many negative losers out there. Don't worry. Try to be more positive. Science and private enterprise will solve the problems.”
Well, many people know that our way of living is unsustainable but they don’t want to live in an environmentally friendly way. They prefer to use a private car instead of public transportation, and they prefer to travel by air instead of trains. They prefer to eat cheap pork from factory farms. They are like nicotine addicts who know very well that smoking is harmful and causes cancer but they keep on smoking anyway.
