Using a greenhouse to battle greenhouse gases
The UN Environment Programme has just published its "Kick the CO2 habit" guide to beating greenhouse gasses as an individual.
Suggested methods include shutting down your computer at lunchtimes, jogging in the park rather than using a treadmill and drying clothes on a washing line rather than in a tumble dryer.
What many Brits may not realise is that they can be eco-warriors in their gardens too.
Growing plants helps to absorb the CO2 in the atmosphere, providing oxygen and helping to slow global warming by reducing greenhouse gasses.
Also, growing your own fruit and veg can not only save money, but also reduce the need for foodstuffs to be transported to the shops.
These simple pleasures can be even more rewarding when you know that you are doing your bit for the planet.
A recent report by economist Sir Nicholas Stern suggested that if no action is taken against climate change, the cost to the global economy could be between five and 20 per cent.
