Wasn't the weekend glorious? Saturday was the first day this year I was able to get outdoors and tart-up my garden. I cut the grass, forked over borders, gathered up fallen leaves, cleared old growth, sowed some seeds and enjoyed coming across some of the things that share this space.

There was a shield-bug, loads of fat worms, a couple of bees, a comma butterfly and an early painted lady butterfly; maybe it's from one of those grow your own butterfly kits that kids and organic gardeners love? Either way, the sunshine and fresh air left me feeling energised.

It was all so enjoyable I lingered into the evening, hoping to catch sight of the International Space Station scooting across the evening sky (I missed it yet again). The shocking truth pulling the rug from beneath this relaxing moment was that there wasn't a minute when I couldn't see at least one jet  plane in the sky.  With five airports, London's airspace is pretty busy.

Today, a new report commissioned by the RSPB, HACAN and WWF has been published raising doubts on the assertion that London's economy will benefit from increasing airport capacity.

It's been the assertion that London's economy is reliant on expansion that has driven Mayor Boris Johnson to pursue the creation of a mega-hub airport in the estuary (which he wants to call Margaret Thatcher International to "scare visitors" - call me naive, but I thought we wanted to attract visitors?). It seems the whole debate supporting airport expansion is built on flimsy foundations.

Flimsy or not, the real foundations for infrastructure development like airports involve a lot of concrete and tarmac; and an awful lot of space. Just like in my garden, stuff lives in these spaces. The cost of losing nature doesn't seem to worry the airport expansionists. They assert they can build new spaces for nature. 75% of Crops worldwide are pollinated by insects as are 94% of wild flowering plants. Bees, butterflies and more are vanishing at an alarming rate. Replacing wild spaces with new runways is not the way to support nature.

As the charity Buglife states, 'it's the small things that run the world'. Shrinking numbers of garden birds are a warning sign that nature is in touble. Rather than seeing airplanes soaring over my home, I'd far rather see developers investing in schemes which improve nature; allowing our communities, our economies and our well-being to soar. Protest against airport expansion by sowing native wildflowers and shrubs in your gardens and community spaces. That way, air passengers will be able to see a riot of colour indicating public support for nature as they fly into the Capital. Say it with flower power.
