When I held my first grandchild in my arms, my perception of time was transformed. I began to ponder what his life would be like. I reflected on how it would be shaped by our responses to the challenges we are facing today—global climate change, economic uncertainty, nanosecond technology and the eclipse of the American empire. I realized that as a grandparent I will have to do my best to ensure that the world will become a safe and healthy place for my grandson and all the other children born in 2010. In an interdependent universe, after all, there are hardly any private actions; everything we do reverberates across the planet. What we do in the present shapes the future and the futures of those who follow us. We are always planting seeds for fruit that we will never harvest.
