I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics.

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.

The environmental movement can only survive if it becomes a justice movement. As a pure environmental movement, it will either die, or it will survive as a corporate 'greenwash'. Anyone who's a sincere environmentalist can't stand that role.

Genetic engineering has never been about saving the world, it's about controlling the world.

Nobody defines it as something women shouldn't be doing. In a way, there are more mathematicians, more doctors, more scientists in India than there are in this country. We even had a woman head of state, and that's something the United States has yet to catch up with.

The first issue that compelled me was a very strange split between India being highly development scientifically (we were the third biggest scientific manpower in the world then) and yet at the same time struggling with amazing poverty. The linear equation that says that modern science equals progress and the reduction of poverty did not apply to India. It wasn't working.

As usual, in every scheme that worsens the position of the poor, it is the poor who are invoked as beneficiaries.
