Plant biotechnology and renewable resources are the driving forces behind a more sustainable development of agriculture and other related industries in the world. Until the 21st century, the main task for most industries was to raise the volume of production to gain the highest profits possible. Non-renewable natural resources, such as oil, were the most profitable sources of energy. This tendency not only exploited these resources but had harmful side effects: growing environmental pollution and changing the earth into a desert, suitable neither for animals nor human beings. At the beginning of the 21st century, both scientists and green movements warn that it is necessary to change this philosophy of economic progress towards a more intensive exploration of renewable resources. Biotechnology is one of the very important and novel tools for obtaining diversified materials on the base of renewable resources. They can serve as a source for production of energy, novel materials, fibres, food, agrofine chemicals and composites. It is believed that diversified possibilities for using natural green resources and their processing can ensure balanced progress without side effects on the earths environment. This book presents research on the possibilities of creating progress in the processing of renewable resources within the study of biotechnology.
