SILENT SPRING: A LEGACY OF SILENT SPRING: ORGANIC FOODS
Most agriculture was organic before humans developed artificial fertilizers and pesticides in the 20th century.
Although the modern organic farming movement began in the 1940s, before Silent Spring, Rachel Carson’s book increased public interest in alternatives to chemical use.
While yields per acre of organic crops are generally lower than crops using artificial fertilizers and pesticides, there are benefits:
- lower energy use per acre
- less environmental impact
- possible reduction in risks to human health
Increasing by 20% a year
Organic food accounts for only 1–2% of total food sales worldwide, but it is the fastest-growing area of agriculture, increasing by 20% a year since the early 1990s.
World organic food sales increased from US $23 billion in 2002 to $52 billion in 2008.
