Byproducts of Urban Life.

Urban life produces severe byproducts harmful to its ecosystem. Sewage is one such example. It is a type of wastewater that includes human faeces, household wastes that drains out as end-product. Developed countries pay highest attention to this issue as not only public health but the surrounding ecosystem, specially fisheries in the nearby rivers and lakes can get close to extinction, while developing countires overlook the issue simply on public hand. Sewage channels or drains are not enough, the wastewater needs to be treated before discharging to the nature, so that nature can do rest of the cleaning. Wastewater treatment is always to aid nature by not letting it overwhelmingly disrupting its cleaning capacity. Let us be more conscious about our wastes and help the environment becoming more healthy.

Green Tech for Green Planet

Plants, since the first Man walked on earth, became his friend,..... silent, beneficial and sacrificing for the highest creation in the universe. What a gift from God!! They will never speak, may be you will hear the whisper among the leaves if you care so. Being green, they put a beautiful pleasing color for our eyes. But this is not all. Scientists are now using plants to detoxify contaminated land. As industrialization is rapidly moving fast on the globe, more and more new areas are getting polluted which first and foremost threatens the ecosystem. Now plants can be used to extract these toxic contaminants from soil or wastewater. Althoug a long ways still to go, but some plants already showed promising results. Sunflower, as an example used in Chernobyl, to extract radioactive Uranium. At the end of extraction plants die but again silently. Where on earth there is a friend like this standing just next to you. What a Grace!!
