Carbon and biofuel footprinting of global production of biofuels

It is an established fact that the Earth is sensitive enough to respond to the activities of humans. It is also an open secret that if we move in accordance with the will and nature of Earth with actions parallel to the nature of this beautiful planet then it will reciprocate with blessings for humans, if not then the whole of humankind must be ready to face the wrath of nature in one way or another or even face the possibility of a threat to the very existence of humankind. Biofuel is one of the most stunning alternatives to carbon petroleum products. The emission of carbon and other harmful greenhouse gases from the petroleum fuel are creating numerous problems to the health of people and also threatening the planet generally. However, biofuel is a product which can not only sort out the human need for fuel but also create the least amount of problems for nature. In this chapter we discuss the different types of biofuel, particularly in agriculture, where the residues and waste have a great impact and use in biofuel mechanisms. On the other hand, we have limitations from an agricultural land point of view because it could change its basic nature of the land from the crop cultivation point of view.
