Did you know thousands of fruit trees go unpicked in parks, streets and back gardens every year?
That means a lot of apples and pears go to waste.
But thanks to a growing trend, groups of people are getting together all over the country to stop that from happening.
The groups are calling themselves Abundance and they are popping up in towns and cities everywhere - there's around 30 groups and counting.
They head out to local spots to collect all the unwanted fruit and take it to places like schools, community centres and even jam-makers!
