For almost five decades, [Dr. Vandana] Shiva has been deeply engaged in the fight for environmental justice in India. Regarded as one of the world's most formidable environmentalists, she has worked to save forests, shut down polluting mines, exposed the dangers of pesticides, spurred on the global campaign for organic farming, championed ecofeminism and gone up against powerful giant chemical corporations. Her battle to protect the world's seeds in their natural form rather than genetically altered and commercially controlled versions " continues to be her life's work. "I couldn't understand why were we told that new technology brings progress, but everywhere I looked, local people were getting poorer and landscapes were being devastated as soon as this development or new technology came in," she says. "No one was stopping to ask: what will be the impact on the environment? What will this cost the farmers? They only wanted to win the race and control all the world's seeds." Currently more than 60% of the world's' commercial seeds are sold by just four companies, which have led the push to patent seeds, orchestrated a global monopoly of certain [genetically modified] crops such as cotton and soya and sued hundreds of small-scale farmers for saving seeds from commercial crops. Shiva considers her most important work to be her travels through India's villages, collecting and saving seeds ... setting up more than 100 seed banks, and helping farmers return to organic methods.
