With 8.3 million people living in London you may be excused for thinking there is not much space for everyone - but an alternative map of the capital has blown this fallacy out of the water.

The map illustrates 62 per cent of London is comprised of open greenspace and domestic gardens, while just 14 per cent of the capital is buildings and 12 per cent roads.

Within the city's limits there are 3,000 parks, 142 local nature reserves, 36 sites of special scientific interest, four UNESCO world heritage sites and two national nature reserves, and 3.8 million private gardens.

There are also 13,000 wild species as well as lots of cats and dogs.

For its size, London is one of the greenest cities in the world – something to celebrate.

The map has been put together by Greater London National Park - a website campaigning for London to be turned into the world's first 'national park city'.

It uses the Office for National Statistics generalised land use database (2005) to reveal the alternative picture of the capital.

If you can imagine London becoming the world’s first 'national park city' - with the main aim to conserve its communities, wildlife and habitats - add your name to this petition.
