Rachel’s home, 1963 
N1: The chemical companies say Rachel’s book Silent Spring is a hoax. 
N2: But the book is a best seller. 
N1: A television reporter comes to her house. 
Reporter: Miss Carson, the chemical companies say their products are safe. 
Carson: These companies aren’t here to protect the public. They want to make money.
Reporter: About 900 million pounds of pesticides were used last year. Are they all harmful?
Carson: The problem is that pesticides don’t just kill bad insects.  
Reporter: Please explain.
Carson: Say bark beetles are spreading disease in elm trees. 
Reporter: OK.
Carson: DDT is sprayed on these trees to kill the beetles. 
Reporter: That’s good, right?
Carson: But the leaves of these trees are now coated in poison. The leaves fall to the ground. Then earthworms eat them. 
Reporter: I see.
Carson: Birds eat the earthworms. Now the birds are poisoned. 
Reporter: Is DDT harmful to humans?
Carson: Cows eat hay that has been sprayed with DDT. 
N2: The reporter nods. 
Carson: DDT ends up in the milk and meat we get from those cows. This can make people sick. It can even cause cancer. 
Reporter: Why did you write this book, Miss Carson?
Carson: Because when humans go to war with nature, nobody wins.
