    Qureshi started a group called Urban(city)Forest. The group plants trees in cities across Pakistan. For its first project, Urban Forest planted about l, 300 trees in a park in Karachi. Qureshi hopes the park will one day become a forest of 50,000 trees.

    Since 2015, Qureshi and his team have planted eight urban forests in Pakistan. Six are in Karachi. The trees help cool the air. They are homes for birds and insects(昆虫), too. Some trees grow fruit for people and animals to eat.

First, he met with students to teach them how trees help the environment(环境).Then students planted trees in the schoolyard. The trees make birds and colorful butterflies come to the schoolyard. Students go outside during science class to study the forest.
