"As someone who is from the medical field, I do believe that everything roots from science. And I think that the greatest gift that we have in this generation is the sophisticated technical installations that we have, and so there is science in the phaseout of fossil fuels. But one thing that we can also agree on is we can always live the zero-waste and sustainable lifestyle. I've always been practicing it because sustainability will always ensure the stability in our future. And if we can master the transferability skills from a just phaseout, then we will have a greener and more sustainable future."
