Plants are important natural resources to live and sustain human life. Plant products are essential for human activities including caring and curing. If life of human being depends totally in plants how it is sustaining or continued in near future?
It depends on what you consider "life". Plants sustain the trophic chain supporting human life, but human life is also supported by minerals, water and others.
Dear colleague Ramesh Prasad Bhatt :The sustainability of man towards the future depends on his judgment on rational use of natural resources and to develop production systems that reconcile the cycle "soil-plant-man-animal", all living beings on the planet, both biotic and abiotic carry and contain elements, data and information known in some cases and in others discovered, which can be vital in any field of knowledge of current and future science. The challenge is to promote and practice, knowing that in plants, a bird, in a geological layer may be the future of mankind responsible for the conservation and protection of nature human behavior.
