World Environment Day is celebrated every year on 5 June in more than 100 countries. The theme for 2009 is climate change and the broader consequences of environmental change, and what societies can do in response.
Combating climate change and preserving ecosystems services that underpin our economies is an issue for everyone. Every individual’s efforts, no matter how small, can contribute to the sustainable development of our economies and communities around the world.

There are much better ways to travel than in a petrol-fuelled carThe average car emits a kilogram of carbon dioxide for every five kilometres travelled. A typical car in a typical year might emit three tones in a year.
The average passenger on a bus journey is responsible for a half that amount, for every kilometre travelled. And the average train traveller only a third. So public transport is better, especially if you are travelling alone. (And, in practice, the bus or train will make the journey anyway, so your hopping on board emits virtually nothing.)
If you must drive, hybrid cars are the latest mass-market attempt to reduce fuel consumption and so reduce pollution. They still run on petrol, but the petrol powers up a battery that in turn drives the car. This way the fuel is burnt at optimum efficiency. Other low-carbon alternatives include diesel engines, running your car on LPG, which requires retro-fitting, or on biofuels, which does not. In fact, thanks to an EU directive, most forecourts will soon be selling petrol with 5 per cent biofuel additives, so we will all be part of that revolution without knowing it.
But the real trick is to run your car less or, if you can, abandon it altogether. In many urban areas with good public transport systems, cars are more a hindrance than a help in most day-to-day journeys. Keep your kids (and you) fit by walking them to school. Ride your bike to the shops or the gym. If you have to drive, whether to work or school or for shopping, go with a friend. Driving in a car alone when you could share is an environmental crime. If it's a gas-guzzling SUV, so much the worse.
Think local. We all travel around far more than we need. It's time-consuming and often highly polluting. Use the neighbourhood store, school, park and cinema. If you are buying a new home, think about living in the city rather than in a suburb where the car may be an essential. Live near your work. Not everyone can arrange their lives this way all the time, but it will save time as well as reducing your climate footprint!!!!
And in the air
Do you really need to take that flight?Should we fly?
The short answer generally is try not to fly if you can avoid it. A new movement is starting up of people who refuse to fly, not through personal fear, but because of fear about what all those aircraft are doing to the atmosphere. Short-haul flights typically produce as much carbon dioxide per passenger per mile as a car with one occupant, though long-haul flights are a bit better. A trip from London to New York and back emits as much as a typical car driver does in a year - about half a tonne of carbon.
