The Pacific Gas and Electric Co (pg&e), California's biggest natural gas company, has announced plans to buy natural gas generated from cow manure in the state dairy farms to fuel its power plants.

In India, primarily cattle dung is being used as an organic substrate for the production of biogas, however, majority of biogas digesters are underfed. Thus making it essential to evaluate other available organic sources for biomethanation. Various other animal wastes like poultry droppings, sheep droppings, rabbit droppings etc have been evaluated for biomethanation. Beside this, plant and crop residues have also been subjected to the process of anaerobic digestion under different conditions.

India's heritage of natural habitats and wild species is under growing threat from its biomass-dependent rural peoples and its consumeristic urban economy. As the mainstay of its wildlife conservation effort, then, India's wildlife reserves continue to face a range of extractive uses.
