TED: Every day you live, you impact the planet | Jane Goodall

The video discusses ultraviolet (UV) light, focusing on far UV C light, which is effective in killing viruses and bacteria while being safe for human exposure. Far UV C light has a shorter wavelength, making it unable to penetrate living cells, thus safe for skin and eyes. It can be used in indoor spaces to reduce virus transmission, including COVID-19. The video also addresses the challenges of implementing this technology, such as production capacity and cost, and highlights its potential as a tool against future pandemics.
