The global problem of biodiversity loss, especially vegetation loss has been of concern since humans realized the implications of habitat destruction in the course of economic development. Plants form the bedrock of life and human material culture depends on them. Our human world has been so closely tied to plants that it is difficult to imagine human existence without them. Being the only primary producers, all other consumers in the food chain are dependent on plants for food, fibre and energy. Knowledge of plants, their habitats, structure, metabolism and inheritance is thus the basic foundation for human survival and the way a people incorporate plants into their cultural traditions, religions and even cosmologies reveals much about the people themselves.
