"The only safe rule is to give more than we can spare. Our charities should pinch and hamper us. If we live at the same level of affluence as other people who have our level of income, we are probably giving away too little."

If success or failure of this planet and of human beings depended on how I am and what I do... How would I be? What would I do? We may now care for each Earthian individual at a sustainable billionaire's level of affluence while living exclusively on less than 1 percent of our planet's daily energy income from our cosmically designed nuclear reactor, the Sun, optimally located 92 million safe miles away from us.
