Heather Matteson, Materials Scientist, Nuclear Reactor Operator, Environmentalist, Co-Founder of Mothers for Nuclear: I believe nuclear power advocates care about and want the same things as most Sierra Club moms and members. We want everyone in the world to be able to care for their children like we can for ours. We want a world of less air pollution for our kids. I changed my mind about nuclear, and my dad changed his mind, too. We might be destroying the planet, just like my dad thought. But in the end, we both came to think humanity is smart enough to save it.
