  • Graham Marshall

    Mr. Keshan Perera

    Wildlife and Nature have been consistent throughout my life. I have always been fascinated by the
    natural and developing world.

    I strongly feel that science has the potential to produce a sustainable planet if people are educated to
    understand its value. And my introduction to WNPS was no different. I first encountered the committee
    during one of their “Education for Conservation” programs held at my school in 2018. The program
    convinced me to join the WNPS Youth Wing, strongly believe that this committee is an exceptional
    platform to create awareness and execute conservation efforts. Currently working as a Junior Trainee
    Architect, I serve the organization by leading the Youth Wing to achieve its purpose.
