The boundless capacity of the African American spirit in this country to say Hallelujah anyhow, to use our joy as a weapon, to use our creativity as a weapon, to use our moral clarity and our deep experience as a weapon not just to save Black people but to save all of these people.

Listen, here's reality. It is completely unfair and absolutely necessary that people who have been oppressed and marginalized have to lead everybody. That is MLK, that is Dolores Huerta, that is Fannie Lou Hamer, that is Ella Jo Baker, that is Nelson Mandela. You walk down the line.

We seem to forget that everything that is good for the environment is a job. Solar panels don't put themselves up. Wind turbines don't manufacture themselves. Houses don't retrofit themselves and put in their own new boilers and furnaces and better-fitting windows and doors. Advanced biofuel crops don't plant themselves. Community gardens don't tend themselves. Farmers' markets don't run themselves. Every single thing that is good for the environment is actually a job, a contract, or an entrepreneurial opportunity.
