Lake-hopping is Anoop Ambili's thing. For Ambili, a paleoclimatologist, the Lonar Lake in Maharashtra, Tso Moriri in Ladakh and Renuka in Himachal Pradesh hide clues that help him reconstruct past climate changes going back to 10,000 years. Ambili is also studying microplastic pollutants in these freshwater lakes. For example, he is looking for pollutants such as microplastics in Renuka lake, a popular tourist spot and also the largest lake in Himachal Pradesh. Information about the changes in the lakes, Ambili believes, will shape how we design policies that address human-caused changes to natural ecosystems. In this episode, you'll hear what India's lakes tell us about our past, present and future. If you listen to Ambili's poignant observations of lakes and the challenges they face today, I'm sure you'll look at these water bodies from a different perspective.
