Biodiversity is disappearing because of global companies and their monoculture practice. Because we buy products from the other end of the world. Because we eat burgers and processed food, made in factories. Because we use make-up and facial creams and air fresheners. We are their market.
If we make our stuff, our food, if we eat less meat, if we use natural toiletry products made by ourselves, big companies will lose their market and they will have no reason to kill nature.
