There is a real danger of losing our tenure on this planet altogether.
We've got to care about this matter of global warming
because if we don't do anything about it
there won't be anybody here.
During my lifetime the big change that's happened to the world
has been the development of machines and devices and inventions.
It's about time we went back
to taking an interest in the environment.
The Earth has an impossible atmosphere.
For it to have happened by accident,
the odds against it run into countless billions-to-one against.
So something's going on.
I tend to think of the Earth as alive in a sense
like an animal or a plant or any other living thing.
Gaia looks after us.
What happens to the planet
when more carbon dioxide is put in the air?
The Earth will get hotter.
It will heat up to a point
where no life on it of our kind will be possible.
Take an interest in the natural world,
in plants and animals and things that grow naturally.
Not worry too much at all about schooling.
The three R's yes, they're very important, but all the other stuff
I think could be ditched in favour
of a better understanding of the world.
There are answers of various kinds
but I think it needs the right sort of politics
to change people's thinking about these things
and I'd like to see these youngsters using their energies
and their talent in this way
rather than looking for some techy answer
because I don't think the answer's going to come that way.
I think we have all the things needed to stop global warming
we're just not using them.
