"Silent Spring" is proof that the left values nature over human life. Rachel Carson's alarmism led to the banning of DDT in Africa which resulted in more mosquitos, resulting in millions of human deaths due to malaria carried by mosquitos.
This is the difference between the secular left and the religious right. Most people who believe in the Word of God (Bible) believe that the earth was put here to serve us. Many on the secular left like the radical "Earth First" activists feel we should put humans second to nature. Lack of faith in the Almighty results in constant alarmism and constant crises - man made global warming, second-hand smoke, cancer-causing silicone breast implants. Without faith, we become chicken littles like the left.
