There is only one party that is serious about the environment and in a position to defend it: the Liberal Democrats. That's why it's vital as many Liberal Democrat supporters as possible take part in the day on action on 5 December.
Between 7 and 18 December, Copenhagen hosts a major climate change conference, during which the world's leading nations will attempt to negotiate a successor to the Kyoto Treaty.
We are seeing the horrors of climate change already: in the thousands forced to live in caravans after the great floods of 2007; and across the world, in places like Bangladesh being buffeted by cyclones and rising sea levels.
On Saturday December 5 there is a day of action in London including a march on Parliament to publicise its importance.
We are the party that will go furthest on cutting carbon emissions. We will go furthest in generating renewable energy. And we will go furthest in insulating homes.
The Liberal Democrats will make Britain carbon neutral by 2050 - and by 2020 will have brought our emissions down to the level scientists say will stop climate change.
But this will only happen if we take power at the next general election.
That's why it's vital as many Liberal Democrats as possible take part in the day on action on 5 December.
Please try and make it on 5 December and help us show why there's only one party that is both serious about the environment and in a position to exact real change.
The next parliament is likely to be the last that can stop dangerous climate change. And there is only one party that is both serious about the environment and in a position to exact real change: the Liberal Democrats.
Copenhagen is a vital staging post in the international fight to reduce carbon but the Government is not up to the task of driving through changes.
Labour has failed to cut emissions in the past and refuses to commit to what science demands in the future. We are still at the bottom of the European league table for levels of renewable energy, only above Malta and Luxembourg.
The Conservatives are a laughing stock on the international scene and their environmental policies consist merely of empty platitudes.
The Liberal Democrats are different. We are the only party in UK politics with the vision, policies, ambition and ability to kill carbon emissions.
We will make Britain carbon neutral by 2050. We will reduce emissions faster and more effectively than any other party. And we will make sure that every home is properly insulated within 10 years of taking power.
There is only a small window of opportunity to stop dangerous climate change. Only the Liberal Democrats will take it.
