Indoor Air Quality and Green Plants

The speaker shares a personal story of becoming allergic to Delhi's air and discovering that three common plants—Areca palm, Mother-in-Law's Tongue, and money plant—can purify indoor air. These plants can reduce fresh air requirements while maintaining air quality standards. Implementing these plants in buildings has shown health benefits, increased productivity, and energy savings. The speaker emphasizes the environmental importance of this approach, given the growing energy demands and urbanization. The talk concludes with a call to action inspired by Mahatma Gandhi.
