We invite you to look at Nature. Find those secret corners, pieces that were left over, the apparently abandoned spots of a garden (yours or nearby). You may be surprised by finding a web of interactions. If you look at natural systems, you rarely find plants growing in evenly spaced out straight lines – instead, polycultures are Nature’s way of cultivating. Moreover, besides plants, there is an intricated web of life and relationships between them, animals (especially insects) and fungi. In all these relations, there is competition, parasitism, and symbiosis.
