Arbor Day

Arbor Day is a holiday all about trees. The word 'arbor' means tree in Latin. On this day, people plant new trees in their neighborhoods and parks. It is a great way to help the Earth and make the world a greener place.

How It Started

The first Arbor Day was held in Nebraska on April 10, 1872. A man named J. Sterling Morton wanted people to plant more trees on the open plains. On that first Arbor Day, about one million trees were planted. The idea spread quickly across the country. Today, many countries around the world celebrate Arbor Day.

Why Trees Matter

Trees give us clean air to breathe by taking in carbon dioxide and releasing oxygen. They also provide shade, food, and homes for animals. Trees help stop soil from washing away during storms. Planting trees is one of the best things we can do for the planet. On Arbor Day, schools and communities work together to plant new trees.
