World Environment Day is celebrated annually on 5 th June to encourage awareness and work towards preserving the Ecosystems. We all depend on healthy environment for our survival but unfortunately people have been destroying the nature for their personal benefits. With this challenging situation, the World Environment Day is focused on the ecosystem restoration and the theme for 2021 is “Reimagine. Recreate. Restore.” which means preventing, halting, and reversing environmental damages. Every year a country is given the responsibility to host the event. This year Pakistan has been selected as a host in recognition of its efforts in environmental conservation and protection through various policies and programs being implemented in the country. All around the world events are celebrated to raise awareness about the environmental protection. A similar program was organized by the NUMS Department of Public Health under the supervision of HOD Prof Dr. Uzma Hassan. Associate Professor Dr. Tamkeen Jaffry briefed the students about the importance of the day and guided how they can contribute in this noble campaign. Students participated by designing posters to highlight the importance of tree plantation and prepared models to emphasize the value of recycling. Additionally they made a short video to share all the relevant information regarding growing trees, cleaning up trash and proper use and disposal of plastic products to protect our ecosystem
