People thought gaia was crazy until lovelock"s theory. Used by gain theorist - lynn margulis. Most of the time the earth has been around - it has been populated by microorganisms they have the important role of establishing the balance of life through endosymbiosis. Carson got a letter from olga hutchenson. Birds fall from sky, go into toxic shock and die. Carson wrote silent spring as a response to this. Ingested by small organism, eaten by bigger organisms. Ddt now illegal and us and canada - since early 70s. Used scientific arguments against silent spring and promoting ddt. Before her, there was no clean air act, clean water act etc. Reader"s digest didn"t let carson publish an article in their magazine about ddt etc so she decided to publish her own book. Cbs news aired the interview with carson even though all the sponsors backed away. Sun intensity increased by 30% but earth - gaia - temperature hasn"t changed.
