There are many and different ways of approaching and deepen in the reflection on the ecological crisis and globalisation in general, or, more specifically, on genetic engineering, biotechnology, production and reproduction, free trade, poverty, health, food. One of the best means since it covers both possibilities, to my mind, is that one that offers the thinking and ecofeminist practice of Vandana Shiva. Hence I start highlighting that is a good idea to publish a book like this with Anna Cervera that contributes to spread and discuss the work of one of the most active women, known and recognized worldwide, both from feminism and the environmentalism or the alterglobalisation movement. The reasons for introducing ourselves into her vision abound. Her scientific training, being a voice of the South, her practical commitment to the poor of the earth and also to women, present and evident in her writings and speeches at various international forums, favour criticism to the development and economic growth generator of inequalities, poverty and degradation of the natural world, both locally and globally. A thought and a practice that responds strongly to what is judged as a "bad development" and that, conversely, adopts a perspective of subsistence, that one that comes from the basic needs of life.
