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.

Water must be free for sustenance needs. Since nature gives water to us free of cost, buying and selling it for profit violates our inherent right to nature's gift and denies the poor of their human rights.

You are not Atlas carrying the world on your shoulder. It is good to remember that the planet is carrying you.

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.

Although two thirds of our planet is water, we face an acute water shortage. The water crisis is the most pervasive , most severe, and most invisible dimension of the ecological devastation of the earth.

When I find too many puzzles about the way explanations are given about why there is inequality - why people who work the hardest in the world end up being the poorest - I can't just sit back and not try to understand why the gaps between people are increasing, or why there are so many homeless and hungry people in the world.

The primary threat to nature and people today comes from centralising and monopolising power and control. Not until diversity is made the logic of production will there be a chance for sustainability, justice and peace. Cultivating and conserving diversity is no luxury in our times: it is a survival imperative.
