I don't know whether other people have seen this/ know about it, but I thought it might be of interest.

It's a petition to be handed in by a group of London Councillors to Boris Johnson and
the London Assembly this Wednesday (8th).

Many of London's parks and open spaces no longer provide respite from pollution.
Maintenance staff drive around in large trucks and use ear-splitting
power-tools. Worst of these is the leaf-blower used all year round whether
there are leaves or not. They are used by local authorities in housing estates
parks school playgrounds practically everywhere. Research shows the fumes and
dust they emit are dangerous to the public while the air blasts are cruel to
wildlife and damaging to plants.

The petition is calling for these machines to be banned from local authority use
and for petrol trucks and chainsaws to be withdrawn from parks and green spaces.

To view the petition and sign it please Google the Gopetition site and type in
'petrol-free parks' into that site's search engine or at
