"An estimated 100 million sharks are fished out of the world's oceans every year. Take a minute to mull over that figure. That's over a quarter of a million animals each day … If this number of humans were killed in a year, it would be called genocide. There is a name for what is happening in our oceans today: it is ecocide."

"When we set aside MPAs we protect the marine habitat. When we do that, fish stocks recover. Which supports food security. When we create MPAs, we protect the coral, which protects the shoreline and provides shelter for fish. Marine Protected Areas are places people want to visit for ecotourism, so it's good for the economy. It has, if you'll pardon the pun, a ripple effect. Marine Protected Areas are good for the world economy, for the health of the oceans, for every person living on this planet."

"For us to find lasting peace between people, we must first make peace with nature."

"I always feel nostalgic when I disembark (off a ship). It's not that I don't like land. I just love being at sea."

"To succeed as a pioneer you need two things: ignorance and purpose. Ignorance of just how tough the path ahead will be. And a driving purpose, which keeps you going nonetheless."

"Most Channel crossings are won or lost before the first stroke is even taken."

"Never, ever did I think that there would be a debate in this arid country about which was more important – gas or water. We can survive without gas. We cannot live without water."

"Look around the world. Wherever you damage the environment, you have conflict. We have had enough conflict in [South Africa] – now is the time for peace."

"Now is the time for change. We cannot drill our way out of the energy crisis. The era of fossil fuels is over. We must invest in renewable energy. And we must not delay."

"The right to have our environment protected for the benefit of our generation and the benefit of future generations is our most crucial human right. I do not say that lightly - especially given South Africa’s past."

"We cannot afford the luxury of cynicism or even pessimism in our reaction to climate change. The situation is too serious. We must tackle it head on – and immediately."

"I have seen what the challenge of the impossible does to some athlete's minds - once their minds accept that the impossible is achievable, their bodies soon follow."

"Afterwards, I saw a visible transformation in Pugh, and was reminded again of the power of a single event to change a sportsperson's life radically. I have witnessed this twice in my career - once when Joel Stransky kicked the winning goal in the 1995 Rugby World Cup final, and now with Pugh's North Pole swim. Both became more complete and confident people after achieving such sporting milestones."

"Lewis Pugh is a maritime lawyer by training and a pursuer of dreams by inclination. There isn't an ocean he hasn't wanted to swim, or a mountain he hasn't wan't to climb, and it's no surprise that he quit his well-paid lawyer's job in the City of London for a more interesting life."

"He just pulls on his Speedos and gets on with it. It's Britishly mad."

"Philosophy in its very act is a process of translation!"

"We are passengers, comprehended and displaced by metaphor."

"What I would like to show is that there is a vital dimension of their writing, which I call performative reflexivity, which if ignored or misunderstood will impede an adequate response to it."

"Nietzsche would say my friends lacked ears."

"Dialogue never ends not for lack of time or opportunity but for essential reasons."

"To understand how indirect communication is possible we must grasp what it is about ordinary communication that is being changed."

"Nietzsche's problem is how to be a philosopher once he has grasped the finitude of philosophy."

"The point is that philosophy is seen to have come full circle, and to have exhausted itself."

"After Hegel, philosophy confronts the possibility of its own death, and in some sense has to do so if it is to remain the most fundamental kind of thinking."

"Philosophy is an everlasting fire, sometimes damped down by setting itself limits, then flaring into new life as it consumes them. Every field of inquiry is limited, but philosophy has an essential relation to the question of limits, to its own limits."

"The educated man is the man who does not live in immediate intuition, but in his recollection so that little is new to him any longer."

"Like literature, philosophy is not distinguished from other subjects by a specific approach to a subject-matter independent of it. Chemistry deals with chemicals, biology with life and astronomy with very large, very distant objects. Philosophy can boast no such definite subject-matter."

"To say that all philosophy is writing is, minimally, to say that it is never the transparent expression of thought."

"Philosophy is said to have taken the 'linguistic turn' in this century. One hundred years ago, a philosopher would think in terms of mind, spirit, experience, consciousness; now the by-word is language."

"To recognize a difficulty is not to solve it."

"Language steps in where the angels of experience fear to tread."

"The immediate source of ecological crisis is capitalism... Capitalism is a cancer in the biosphere... I believe the color of radicalism today is not red, but green."

"Lead, follow, or get out of the fucking way."

"I do soundbites. Remember, I'm the druid that kicks arse — I'm not the druid that gets up there and waffles for 3 hours."

"Bullying behaviour can be communicated via text, mobile phones, internet, social networking sites, forums. But we can't limit it because these messages are then reinforced by television which glamorises yelling, swearing and vulgar behaviour as the way to walk the red carpet of acceptance."

"There is equality in the office but not on the street"

"Her iron will won international respect. Her unabashed femininity gained women’s. Margaret Thatcher was a lady’s lady."

"Women are more powerful than they think. A mother’s warmth is the essence of motivation. If we could liquefy the encouragement, care and compassion we deliver to our children it would surely fill an expanse greater than the Pacific."

"With all the clever brains in America it would be great to see more investment and focus on this essential research!"

"Tribalism has become trendy."

"Global warming causing climate change may be the ultimate issue that unites us all."

"More than a billion women around the world want to emulate western women’s lifestyles and are rapidly acquiring the material ability to do so. It is therefore vital that in our leadership we display some reserve and responsibility in our spending so that the world’s finite resources will be available for our children, their children and their children’s children."

"The style of kindness has changed."

"If you want to be in with a gang then you have to go along with hiding people's things."

"Everyone wants to be around her because she's always the one at the discos and at the centre of things."

"AAB actively campaigns to reduce aggression and counter bullying by creating peaceful campaigns such as Cyberkind."

"Boris Johnson has real contempt for Londoners. He hates that we celebrate each other's heritage; he hates that we try to pass on a healthy environment to our children; he hates that we look after our most vulnerable neighbours; and most of all he hates that we all expect to share in our city's financial success."

"Gordon Brown thinks you should solve climate change by changing your lightbulbs. We think you should solve climate change by changing your Government."

"Keir Starmer is abandoning so many pledges so quickly, it's sending a real message to people on the left – that they are no longer the party for things like improving child benefit policies, things like controlling rents. It will only be Green MPs arguing for these things in the next parliament, standing up for things like repealing the horrendous Public Order Act, which Labour wouldn't vote against. That does make our job easier in terms of getting elected. But it makes our job harder if we haven't got a decent government – it's concerning on a good-of-the-country level."

"I think at first they were a bit surprised that it had happened, then they realised it was really nice and it was good fun and we got on really well, they were good friends of ours as well so we had a good giggle with them as well."
