National Tree Day is an annual event celebrated in various countries to promote the importance of trees and encourage communities to plant and care for them. It aims to raise awareness about the environmental benefits of trees, such as improving air quality, providing habitats for wildlife, and combating climate change. Typically held on the last Sunday in July in Australia, National Tree Day invites individuals, schools, and organizations to participate in tree-planting activities. Many local councils and environmental groups organize events, making it a community-focused initiative that fosters a sense of responsibility towards the environment.
