Researchers estimate that nine million people die every year as a direct result of air pollution. In London, two million people - of whichare children - are living in areas with toxic air. As our cities grow and more people move into already crowded spaces, what do we need to do to transform our urban areas into healthy places to live?

An increasing body of research tells us that we should be letting nature back in. He studies the role of nature and green spaces in cities and towns, and how we can use the natural world to make urban environments healthier and more liveable. We need trees in our streets, plants in our gardens and flowers on our balcony. We need nature as our neighbour all the time. In return, the benefits to our health would be huge. Even flowers on a balcony can make a difference to our health.

Green spaces in cities mitigate the effects of pollution and can reduce a phenomenon known as the urban heat island effect, which refers to heat trapped in built-up areas. The urban heat island effect appears in towns and cities as a result of human activity. The heat generated by people, transport, shops and industry is trapped in the narrow ro and concrete structures, unable to escape to the atmosphere. Increased temperatures in summer le to an increased demand for cooling. This expands our energy consumption, which in turn intensifies fossil fuel consumption, increasing pollutants in the air and harmful smog on our streets.

Hotter pavements also damage the water cycle. This can be destructive to aquatic ecosystems, as changes in water temperature can be stressful or even fatal for marine life. Planning cities to include green spaces wherever possible is the first step in making our urban areas healthier.

For example, adding a layer of vegetation to rooftops and creating green roofs has proven to reduce the urban heat island effect. Having soil, plants and greenery on our roofs would both reduce surface temperature and serve as insulation for the structures below, reducing the energy needed to heat and cool the buildings. Green roofs can also help regulate rainwater, trapping it as it falls and filtering out pollutants.

Singapore's sky garden is a great example of a city bringing biodiversity into its centre. Trees in our streets also play their part, and a variety of tree species can have a profound effect. If we allow ecosystems to flourish, we have to spend less resources on maintaining them. Cecil recommends going beyond creating pockets of nature within a city. He says, 'If we give space to natural processes and link up our green spaces, we can create flourishing and wild ecosystems in man-made environments.

There were no sightings of the critically endangered smooth-coated otter in Singapore for decades. Now they are returning to the city, because of its dedication to nature. Some natural spaces are messy, but that's a good thing! Messy nature isn't just a great habitat for wildlife but it's good for children to play in.

Children's depression and ADHD is on the rise and one of the reasons is our disconnect from nature. Simply having access to green spaces in cities can do wonders for our stress levels and concentration at work. Cecil says, 'People need to interact with nature whenever the opportunity arises. Something as simple as a five- to ten-minute break during the workday can improve well-being and boost productivity.

Right now, however, accessing to green spaces isn't universal - what's more, it can be a driver of inequality in our societies. Ina Lancet study by Dr Richard Mitchell and Frank Popham of 40 million British people found a link between income inequality, access to green spaces and life expectancy. The study revealed that in rural areas with plenty of access to green spaces, the life expectancy of those on the highest and lowest incomes was roughly the same.

However, in urban environments, the gap in life expectancy was staggering. People on the lowest incomes living in cities are expected to live 10 years less than those on the highest incomes. This is due in part to the green spaces available to the richest people, who often live in open, leafy areas, while the poorest are often left living in overcrowded, heavily concreted areas.

Mitchell and Popham's showed that as you move along an axis of increasing access to green spaces, the difference in life expectancy decreases. But the problem can't be solved just by creating green spaces in poorer areas. She says, 'It's not as simple as just creating green spaces in certain areas. The situation we have at the moment is that high-quality urban areas, with good access to nature, are more expensive to live in.

It's a kind of green gentrification. Parks should be easily accessible, democratic spaces - somewhere you can go without the pressure to spend money, and meet people from all walks of life within your community.

It will take some effort to truly bring nature into the heart of our cities, especially to sprawling urban jungles. But there is plenty that all of us can do right now to protect what we have and encourage nature to flourish. By caring for and using the parks and green spaces near us, we show councils that these precious places are cherished. You can also use your voice. Talk or write to those who oversee the public green spaces in your area - in the UK, this would be your local council and MP - about the changes you'd like to see.

We all need to work together to create real change for people and the planet. You can help too. If we act together, we can make a positive difference. Here's how to do your bit to protect nature.
