1. Make our outside spaces wildlife friendly
One in four species of birds, mammals, reptiles, amphibians and fish are on the verge of extinction or extinct. We can do our bit for our local species by making our gardens or outside space more welcoming for wildlife. The RSPB campaign Make a Home offers lots of excellent tips for making your space wildlife friendly.
Even the smallest balcony can offer food and shelter for birds and insects. Wildlife friendly does not have to be untidy, a formal pond will attract wildlife and many flowers adored by the most discerning gardener are equally loved by bees and other insects.
One person in six alive today is chronically hungry. I am not sure that the keenest grow-your-own enthusiast can solve this one but there are things we can do to help reduce food waste and local charities. Maybe you have fruit trees but are unable to pick the fruit or it's simply too much for you to use. Locally Northfield Ecocentre run Urban Harvest which collects unwanted fruit and vegetables and redistribute them to local charities, schools and a local Community Café, the rest is used to create lovely juices and preserves. Thousands of tonnes of fruit goes unused in our city gardens so why not help reduce the waste. Or if you haven't got any surplus why not help by volunteering with the harvest.
Between between 1970 and today 160 billion tonnes of carbon dioxide have been released into the atmosphere, that's more than in the previous 200 years. We can all help by buying plants and sourcing our hard-landscaping materials locally. There are many small plant nurseries which offer a larger and more interesting range of locally grown plants than you will find in the big Garden Centres. When re-designing a planting scheme or garden I always try and re-use or recycle what I can. If it isn't wanted or doesn't fit with the new scheme then there is nearly always someone who can use it, try advertising on your local Freecycle or Streetlife.

The final scorecard fact is that the Earth's population has almost doubled since 1970, and in the same period the share of cropland per person has almost halved. I had to think laterally on this one as I am not sure that I can help with either of these : ) But the message I think we should take is how lucky we are to have public and private green spaces to enjoy. We should celebrate this and ensure that we are making the most of whatever outside space we have - every little bit of green we can create in our cities helps reduce pollution, support wildlife and provides enjoyment not only to us but everyone one who passes by - guess which is my outside space?
