To reconnect with nature is key if we want to save the planet.

We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

We are always talking about how we can get more environmental and humanitarian education. It is about listening to the voice of young people - how they feel, and what would be most meaningful for them.

Farm animals are far more aware and intelligent than we ever imagined and, despite having been bred as domestic slaves, they are individual beings in their own right. As such, they deserve our respect. And our help. Who will plead for them if we are silent? Thousands of people who say they ‘love’ animals sit down once or twice a day to enjoy the flesh of creatures who have been treated so with little respect and kindness just to make more meat.

I have never had an animal that didn't have a personality, one differing from another.

Without the heart to ground it and open it to who we really can be as human beings, the brain is a very dangerous machine. A machine that is saying: we've got to have economic growth; we've got to have unending economic growth, otherwise societies will collapse. And yet there should be something saying: wait a minute, this isn't going to work.

Hundreds and thousands of young people around the world can break through and can make this a better world for all living things. Once young people know the problems and are empowered to act, they have great power to impact the world.
