Nature has gifted this rich biological diversity to us. We will not allow it to become the monopoly of a handful of corporations. We will keep it as the basis of our wealth and our sustenance.

Diversity creates harmony, and harmony creates beauty, balance, bounty and peace in nature and society, in agriculture and culture, in science and in politics.

If you want a cow to be not just a cow but a milk machine, you can do a very good job at that by creating new hormones like the Bovine Growth Hormone. It might make the cow very ill, it might turn it into a drug addict, and it might even create consumer scares about the health and safety aspects of the milk. But we've gotten so used to manipulating objects and organisms and ecosystems for a single objective that we ignore the costs involved. I call this the "monoculture of the mind."

The system of seeds based on monoculture is wrong and inappropriate. The biodiverse system has produced more food, and biodiversity means that seeds must be in the hands of farmers.

The people who see the population explosion in the Malthusian way - as a geometric progression - forget that population growth is not a biological issue. People are not increasing in numbers out of stupidity and ignorance. Population growth is an ecological phenomenon linked very intimately to other issues, such as the usurpation of the resources which allow people to live.

I think we have reached a stage now where we need to find solutions to economic injustice in the same place and in the same ways that we find solutions to sustainability. Sustainability on environmental grounds and justice in terms of everyone having a place in the production and consumption system - these are two aspects of the same issue. They have been artificially separated and have to be put back again in the Western way of thinking.

We will either defend the rights of people and the earth, and for that we have to dismantle the rights that corporations have assigned to themselves, or corporations will in the next three decades destroy this planet, in terms of human possibilities.
