Green roofs improve the quality of urban life - shouldn't all buildings have them?

Rooftops covered with grass, vegetable gardens, and lush tree trunks have become a common sight in many cities around the world. Even more private companies and city governments are investing in green roofs construction. Rooftops like this have multiple purposes and benefits.

First of all, such green roofs contribute to reducing pollution in urban areas and reducing urban heat, because plants absorb carbon dioxide and emit oxygen during photo synthesis, then it can be a habitat for many urban wildlife and thus mitigate damage to an already degraded ecosystem. Beside, it can save energy a and produce food.

According to a recent UK report, the green roofing market is expanding there at a rate of 17% every year. The opening of the world's largest rooftop farm in Paris is expected for 2020, with similar schemes in Chicago and New York. So far, Stuttgart in Germany is considered the green roof capital of Europe, while Singapore has moved on, installing green roofs on buses.

All research is being done on the subject and with the aim of scientifically proving the sustainability and benefits of green roofs and thus persuading developers and investors to adopt green roofs. Why not at the very construction of a building that is just about to be built. There are also researches related to the connection of drainage systems and everything necessary for the construction and maintenance of green roofs in order to manage water. It all even has to do with the mental health of the urban population as doctors increasingly prescribe staying in a green environment, dealing with gardening, and this is also helpful in the fight against obesity.
