After acknowledging that this generation has heard more than its share of doomsday predictions — about ecological catastrophe, national decline, and generational degeneracy — Johnson pushes back firmly. She refuses to accept that any of these fates are foreordained. It is not inevitable that forests disappear, that topsoil erodes, or that famine decimates the human race. Her optimism is not naive; it is invested in the people sitting in front of her. The line pivots from abstract hope to concrete faith in the graduates themselves as the instruments of solutions not yet imagined.
