I wanted to weave a green thread through the Conservative party; that's my job, and I signed up imagining that I would be in a very small minority within my party, possibly even on my own, battling away on these issues.
Sense About Science is much more than an innocent fact-checking service. It is a spin-off of a bizarre political network that began life as the ultra-left Revolutionary Communist Party and switched over to extreme corporate libertarianism when it launched 'Living Marxism' magazine in the late eighties.
The Conservatives are a confusing lot. They first denied climate change was a serious issue and then suggested strengthening the nuclear industry as a solution to it. They oppose the European Union, but support joining North American Free Trade Agreement, despite its obvious failure.
GM has never been about feeding the world or tackling environmental problems. It is and has always been about control of the global food economy by a tiny handful of giant corporations. It's not wicked to question that process. It is wicked not to.
There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.
We've all heard of the surveys revealing that teenagers think cows lay eggs, and others where children can identify more brand logos than trees, by a staggering margin. My view is that children will form a significant part of the green fightback. They instinctively understand the value of the environment.
More passengers fly in and out of London than any other city in the world. We are well-connected, we have ample capacity, and we are starting from a position of strength. The problem is that we don't use that capacity well.
Yes, Heathrow is the U.K.'s busiest airport, but new runways or a new airport are not the answer. It is far better to focus on improving capacity.
'The Ecologist' has lost money from the day it was launched in 1970, and will continue until the last edition is printed. It was never set up as a business venture. It was set up as a campaign, and like all good campaigns, it costs. Its various backers have, over the years, been happy to pay that cost.
'Green' cannot be allowed to become an excuse for stealth taxes. And nor should 'green taxes' be about punishment. Instead, they should represent a switch of emphasis. So if domestic flights are taxed, it should be on the absolute condition that the money is ploughed into improving the alternatives, such as trains.
Leonardo DiCaprio is a rare phenomenon. Whereas for so many celebrities an interest in the environment is a fashionable accessory, for DiCaprio it is a thread that runs through everything he does.
While big business gain subsidies and political access, small businesses drown in red tape, and individuals now risk being classified as terrorists for complaining about it. Economic globalisation is about homogenising differences in the worlds' markets, cultures, tastes and traditions. It's about giving big business access to a global market.
If there was a time when 'The Ecologist' appeared not to be making a difference at all, not doing something useful, I wouldn't do 'The Ecologist,' but I think it is useful.
I am cynical about politicians. My experience of politicians has been thoroughly negative. I have found that politicians are people that can not be taken at face value. There are very few politicians I have been impressed with.
In North America, more than half of all children travel to school by bus. We need a similar programme in London.
Climate change - for so long an abstract concern for an academic few - is no longer so abstract. Even the Bush administration's Climate Change Science Programme reports 'clear evidence of human influences on the climate system.'
We always hear from newspapers that while people understand the environmental challenge, they are unwilling to stomach the solutions. The trouble is, we only ever hear about the solutions from the media, and for whatever reason, they are almost always caricatured beyond recognition. If there's no appetite for green, it's not surprising.
