There are a number of issues with London that can all be addressed with this one simple idea. Unfortunately London has a horrible air pollution problem which is causing illness and strain to our health service. It is also quite grey and lifeless in many areas. The first stage to our idea is to replace many brick and concrete walls with living walls, that do a great job of purifying our air and bring life back into the city. Our second stage is to develop an adhesive trellace-type material to be placed on bus stop rooves and on top of lamp posts to encourage mosses to grow. Our third stage would be to encourage the London Mayor to make sure as many new constructed buildings have a roof garden containing bee friendly plants as he can.

What we'll deliver:

• Install living walls all over London
• Develop an adhesive multi-purpose moss trellace

Why it's a great idea:

Not only does London become a healthier environment. It will certainly look great, it will be great for the endangered bee population and will turn London from a grey metropolis to a green city full of life.

Steps to get it done:

• Buy the requisite materials to build the walls
• Contact London councils as to where we would be granted permission to install the walls.
• Design and build prototypes for the green wall. Or else find an existing green wall solution that can be outsourced.
• Employ volunteers and/or school groups to help erect the walls.
• Rent a large enough area for the green walls to be produced

Improve health.
