So that's a bigger and bigger proportion of the plants being eaten.

And that increases the amount of light which reaches the forest floor.

So the entire ecosystem's changed.

And because nature isn't a linear system, it's hard to be precise about how our forests have changed, but it certainly would have changed a lot.

It would probably have a far thicker depth of leaves, probably good news for kids and grown-ups who want to run around scuffing up leaves.

There's always a joy in the autumn.

But the types of plants which can grow will have changed.

I don't think I needed more enthusiasm for earthworms anyway.

It makes you really appreciate how important they are.

They do so many things for us as a society and for the planet.

They ask for very little in return.

And we should celebrate them and celebrate all that they do for us.

I love the sense of mystery.

When I'm feeling down, I've had enough.

All I need to do is pick up my binoculars and walk outside.
