Talking About Green

A green roof is partially or fully covered with plant life (vegetation) and soil. It could be any growing medium planted over a waterproof membrane. The additional layers which could be included are a root barrier, irrigation system and drainage option.
A green roof can serve as a valuable and readily accessible recreational area and can also help improve the urban climate.
Green roofs, particularly, made of plants which are grown in absorbent substance helps reduce storm water overspill, reduce energy usage, cool the environment and lengthen the lifespan of the building and roof. Green roofs can offset the undesirable heating effect. They are now a big consideration for sustainable and accessible construction.
You can have green walls and roofs which will be alive with lush, weed-free lawn that can even put most of the suburban yards to shame. There are options where instead of grass a succulent called sedum can be used. Sedum is very drought-resistant, it stays green and doesn’t grow very fast so that the maintenance is less. Green roofs works as a non-intrusive, natural building material which creates a confined growing room for plants to flourish and interweave.
Green rooftops are becoming one of the best green living ideas for urban dwellers who long for communal sceneries for occasional entertainment, refuge and complete family relaxation. Green roofs absorb noise, trap dust, recycle carbon dioxide, absorb and break many gaseous pollutants and helps reduce the negative climatic effects of urbanization.

Recently heard about a geography class that grows many vegetables like peas, beans, okra, broccoli, tomatoes, bell peppers, lettuce and potatoes on there green roof and donates all of it.
Especially in the densely populated cities there are very less opportunities to create new green areas. So, green roofs are an excellent method to improve the quality of life. In some countries and cities green roofs are almost compulsory for every building construction.
So, planting on roofs and walls is one of the most innovative and quickly acceptable ideas for eco green living in the worlds of horticulture and built environment.
