4.2 Environmental Degradation & Biodiversity Loss

Lesson 21 of 26 in the free Sustainability Practices notes on Siksha Sarovar, written by Rohit Jangra.

The "Other" Crisis: Nature Loss

While the world is focused on CO2, biodiversity is collapsing at 1,000 times the natural rate. Nature provides "Ecosystem Services" (pollination, water filtration, soil health) worth $125 trillion annually.

1. The 9 Planetary Boundaries: Developed by the Stockholm Resilience Centre, this framework identifies nine systems (like climate, biodiversity, and ocean acidification) that keep the Earth stable. We have already crossed six of these boundaries, putting the Earth in a "danger zone."

2. From "Do No Harm" to "Nature Positive": Sustainability used to mean "be less bad." The new goal is "Nature Positive"—meaning the world should have more nature in 2030 than it did in 2020. Companies are now expected to restore forests, not just stop cutting them down.

3. TNFD: The Nature Version of TCFD: The Taskforce on Nature-related Financial Disclosures (TNFD) is a new framework that forces companies to report how their business depends on nature. For example, a food company must report the risk of losing bee populations (pollination risk).

4. Biodiversity Credits: Similar to carbon credits, these are a new financial tool where developers pay to protect or restore a specific area of nature to "offset" the damage they do elsewhere. However, these are highly controversial as ecosystems are unique and cannot be easily "swapped" or "offset."
