I believe that the tragedy [like terror attack] that's caused so much grief and suffering to so many thousands and thousands of people has also served as a call to action, because many people now are re-examining their own value systems, and the churches, temples, mosques and cathedrals are packed to overflowing for the first time in years.

There are many people out there (me being one of them) who can vouch that animals have feelings; they feel compassion and love, as well as pain!

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.

The more we spread the word, the further it will go and more it will change!

I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.

You cannot share your life with a dog, as I had done in Bournemouth, or a cat, and not know perfectly well that animals have personalities and minds and feelings.

Chimps act the way they feel unless they are afraid of reprisal if they do so. But that doesn't apply to humans.
