Living Wall

These vegetated surfaces don’t just look pretty. They have other benefits as well, including cooling city blocks, reducing loud noises, and improving a building’s energy efficiency.What’s more, a recent modeling study shows that green walls can potentially reduce large amounts of air pollution in what’s called a “street canyon,” or the corridor between tall buildings.

For the study, Thomas Pugh, a biogeochemist at the Karlsruhe Institute of Technology in Germany, and his colleagues created a computer model of a green wall with generic vegetation in a Western European city. Then they recorded chemical reactions based on a variety of factors, such as wind speed and building placement.

The simulation revealed a clear pattern: A green wall in a street canyon trapped or absorbed large amounts of nitrogen dioxide and particulate matter—both pollutants harmful to people, said Pugh. Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.

That’s why the green-wall study is “putting forward an alternative solution that might allow [governments] to improve air quality in these problem hot spots,” he said.Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.

This woman deserves a round of applause and a throne of gold. This is the most realistic & amazing thing for someone to say for this generation of students. I wasn’t able to go to college this year because my parents can’t afford to send me and I had every scholarship, grant, loan known to man and it still wouldn’t work. Finally someone gets it!

I will reblog this until the stars burn out……

white people are very brave when it comes to terrorizing black children who do not have the power to fight back. and are very surprise when someone comes to their defense.

I will reblog until I die.

Don’t look to any outsiders to protect our children.

Will never not reblog
