Large interest groups get medicinal plants collected from the fields and thus they endanger the plant species in natural conditions and many medicinal plants have come in the category of endangered plants due to their overexploitation. One possible answer could large scale fermenter culture of medicinal plants (Ashwani Kumar, Shikha Roy 2006 Plant Biotechnology and its Applications in Tissue Culture IK international, New Delhi; Karl-Hermann Neumann, Ashwani Kumar and Jafargholi Imani (2009) Plant Cell and Tissue Culture - A Tool in Biotechnology: Basics and Application Springer Heidelberg.

Traditional medicines are facing problems in the global market and sometime they are not up to the mark though the formulae are correct, ingredients some times are not botanically correctly identified, contents are not monitored , expiry dates are not mentioned. Famous Chavanprash from famous companies give a list of plants to form ingredients. Its is difficult to establish weather all the ingredients written on the label of the bottle which are vitalize themselves are within the expiry period or have required potency, or have proper chemical composition of ingredients.

Human body has 10 raise to the power 13 cells and it has 10 raise to the power 14 microbes in it if I have heard the lecture correctly delivered in a seminar abroad. Microbes have different interpersonal relations when alone . They behave differently if they are in company of human beings or with different microbes. Microbe human interaction in fat people and thin people is different . In fatty healthy people and in sick thin people the microbe human interaction may be different. Natural products have an effect on microbes and vice versa. Natural products might influence si RNA levels. Its the microbes, natural products and human body which act together,( a doctor can tell better,) but in eastern way of treatment emphasis is laid on curing mind , body and soul together.

I had a chance to pass on the road in front of hospital in West recently. I never had a chance to enter hospital from inside there. I remembered the poem of Ernest Hemmingway “East is East and West is West and twin shall never meet”. Its not to hurt anybodies true feelings its about way of life in east and west and the traditions will always be different because of way of life is different.

Soil has limited potential in terms of productivity and nutrient cycle regulation. Drinking water on the earth is limited. Excessive agriculture destroys soil structure and reduces chemical balance. Not all the minerals present in soil are available to the plants. Set aside lands have their own benefits in terms of regulation of pests and diseases as fallow land will prevent rapid spread of diseases in case they appear and it also improves soil health to have crop rotation.

Using corn or soybean for getting ethanol or bio-diesel additive could be good option for some nations, developing cellulose resources could be another with genetic engineering, while Jatropha is in mission mode in developing world, there cannot be general consensus what should make renewable energy crop.

The opinions may vary and logics could be different. Different paths could lead to same destination replacement of fossil fuel with bio-fuel. This goes with the assumption or scientific fact (which ever way you want it ) that using bio-fuel will help in green house gas mitigation.
