Do you drink orange juice in the morning?

Lots of Americans like a glass of orange juice in the morning.

A lot of America's orange juice is made from Florida oranges.

But over these twenty years, Florida has had fewer and fewer oranges.

Why?

Twenty years ago, Florida's orange trees got a disease.

When a tree gets this disease, the oranges stay small and fall off before they've grown properly.

These oranges don't taste good either.

The disease is brought by a tiny insect.

The insects are so small that with one gust of wind, they can fly to other trees.

Now Florida has ninety-five percent fewer oranges than twenty years ago.

Lots of people have stopped growing oranges.

Florida used to have fifty-four orange-juice factories; now it has only four.

A man who has grown oranges for many years said: this used to be a lively little town.

His orange trees got sick, so he had no choice but to grow other things.

But now scientists have found new ways.

This year, the American government approved two new methods.

The first is a new kind of orange tree that isn't afraid of the disease.

The second is to give sick trees a kind of treatment that helps them fight the disease.

People have already bought hundreds of thousands of new orange trees to plant next spring.

The Florida government is also giving money to help people buy the new trees.

But the new trees will only have oranges in two years.

A man who has worked here for twenty years said: this is the first time in twenty years I've felt hope.

There's another problem: the number of people drinking orange juice has also halved.

Do you think Florida's oranges can come back?
