London's Heathrow Airport is going under major plans for expansion with a recently inaugurated Terminal 5 and plans for a third runway. Activists have been against the expansion due to its effect on climate - More planes means more carbon emissions. This time they came up with a new idea - why not buy a piece of land in the middle of the land planned for expansion.

Celebrities like "actress Emma Thompson, the comedian Alistair McGowan, millionaire Tory Zac Goldsmith", greenpeace and activists bought a portion a land in the middle of Heathrow's expansion project. The land plot is called "airplot" and a thousand of brits have their name on its registration.

Cons 

• More planes, more pollution = more carbon emissions
• More planes - more noise

Pros

• More planes - More jobs
• More planes - More money for London or UK (since every person flying through or from London pays airport tax)

The motley crew (a coalition of environmentalists, scientists and actors) has bought a small plot, about an acre in size, in the heart of the development area where an extra runway would be situated. The group vows to subdivide the property into hundreds, perhaps thousands, of smaller parcels and sell them off to environmental activists around the world, in an effort to bog down the government if it tries to buy up or seize the land.

On Tuesday, the organization announced that 5,000 supporters had signed up to be named as co-owners of the full plot, in hopes of slowing any initial legal proceedings.

"It started like most good ideas around here, with a conversation down at the pub," the environmental organization Greenpeace said in a blog on its British website. "We're now the proud owners of a small piece of land within the site of the proposed third runway at Heathrow."
