We are grateful to all the speakers who set aside time from their busy schedules and spoke to us on various aspects o Environment from 7th November to 11th November 2019 during this year's ELS. All the five days saw a packed hall with a turnout of around 80 audience members. We thank all our friends, the audience members, who keep encouraging us to conduct such programs as the Environmental Lecture Series by turning up in good numbers even on weekends.
