The natural process by which green house gases are removed from the atmosphere is the photosynthesis. But due to rapid deforestation and increasing green house gases (CO2) there could be shortage of oxygen in future. Atmospheric percentage of oxygen is only 21%, still sufficient, due to oxygen cycle. The process of photosynthesis requires CO2, water and a tree. But while percentage of trees going down and down per density of population shortage of oxygen likely. Then how to carry out process of photosynthesis without trees. Is there any method or can it be developed in future?

The question is aimed at offering solutions to the major issues of deforestation, use of agrochemicals and other agro-based activities associated with CO2 emissions. Although the rural poor developing countries may pose a threat since they do more of deforestation, while producers of agrochemicals may also promote their use.

Do we need to track the anthropocene and beyond in coastal sediments in particular or in fresh ponds?If so how do we go about it. I beleive this will be a befitting theme for International Geosphere-Biosphere programme.

Carbon emissions are going high in a steady pace, aerosols are very much present in the atmosphere, Deforestration, Sand mining all will result in critical morphodynamics of coastal region. All these will have impact in the top layer of earth, say 1-3m. Can we distinguish anthropogenic versus natural causes, or can we demarcate anthropocene from Holocene?
