John Shanahan, civil engineer, President of Environmentalists for Nuclear - USA: At Environmentalists for Nuclear - USA, we aim to be respectful and appreciative of the environment and nature in general. As advocates for nuclear power, we aim to have the best managed nuclear power programs for the whole world. That requires cooperation and teamwork across countries to minimize problems. How well can mankind do using nuclear power? To answer this, we look at how well mankind can do displaying nature in ideal situations in botanic gardens. In these photos in the Denver Botanic Gardens, every tree, blade of grass, flower and bush is placed by professional gardeners. We can, we must do as well with nuclear power.
