The Golden rule of the Pot luck

Dr. Stefano Bertozzi started out taking about sin and I wondered if this was just going to lead into another sermon that I could ask the priest at my church for any time. He uses sin to describe our actions. Like he sinned against the people in the African Sahel and in Bangladesh by flying to the ceremony to give the talk. By flying, he put 600 pounds of CO2 into the air. He said these people that suffer the most every time someone takes and takes, but never gives back. He presented the rule of the pot luck. If you bring 2 people to the pot luck, you bring enough food to feed two people. It's not right if you bring 6 people to the potluck and only bring enough food for one or two. If you take from the planet, you have to give back. Now jsut giving back exactly what you took, but more than that. The most blessed people in this world are the people that take very little and yet still give back even more than they took. These people are the people the world needs so desperately. I feel that "giving more than you take" is the main message of this speech.
