     It's known to us that when we taste delicious food, some people are in hunger. They live a hard life. They are poor and always don't have enough food to eat.

     Food banks are the organizations to help these poor people. Food banks receive the food from companies or supermarkets, and also from donations from the public. In this way, they collect extra food and give out the food to people who are hungry.

     The first food bank was St. Mary's Food Bank. It started in 1967 in Arizona. In 1979, it became a larger organization named America's Second Harvest Network-made up of over 200 food banks across the USA. Each year, the Network provides food for more than 25 million hungry people in the United States, including more than 9 million children and nearly 3 million old people.

      Volunteers are important to food banks. There are many different ways for you to volunteer. You can help out through activities such as:

     *Sorting, boxing and packaging donated food.

     *Tutoring poor kids at your local Kids Café.

     *Transporting or delivering food.

      It's simple. Take part in it today, and let's try to make our world without hunger!
