Hi, I am Liao Lichun, a volunteer for environmental protection. I have received such titles as "Most Beautiful Volunteer" and "Beijing Role Model" due to years of commitment to ecological protection on the grassland in Inner Mongolia. Over the past few years, I have led volunteers for more than 15,000 times to participate in greening and environmental protection activities on the grassland in Inner Mongolia, with 1.3 million trees planted, the local ecological environment improved, and biological species enriched. Although the biodiversity of nature has been severely damaged due to human activities, we, based on our practice, really believe that people can bring beauty back to the world by their own hands. Therefore, I would also like to sincerely call upon all human beings to work together to protect biodiversity. I'd also like to invite young people from all over the world to participate in the "Colorful World" International Youth Painting Invitational Exhibition, and use their own brushes to show how brilliant a harmonious earth with biodiversity can be, so that more people can pay attention to the work of biodiversity conservation. To protect biodiversity, we are taking actions!
