What percentage of the Sundarbans mangrove forest has lost its capacity to recover from environmental stress between 2000 and 2024?
Answer: Option
Explanation:
A recent research study published in April 2026 highlights a concerning decline in the resilience of the Sundarbans mangrove ecosystem. It estimates that around 10-15% of the forest has lost its ability to recover effectively from environmental stress over the period from 2000 to 2024. This decline is attributed to multiple factors, including cyclonic disturbances, rising salinity due to reduced freshwater inflow, and human activities like shrimp farming and deforestation. The weakening resilience threatens biodiversity, including key species, and undermines the ecological stability of this critical mangrove habitat.

What was India’s rank in the 2025 World Air Quality Report published by IQAir?
Answer: Option
Explanation:
In the 2025 World Air Quality Report released by IQAir, India was ranked as the 6th most polluted country globally. The rankings were determined based on PM2.5 data collected from thousands of monitoring stations across numerous countries. Countries like Pakistan, Bangladesh, and Tajikistan ranked higher in pollution levels. The report also highlighted that only a small percentage of countries met the World Health Organisation’s recommended air quality standards. India’s position reflects ongoing environmental challenges, particularly in urban areas, where pollution continues to impact public health and quality of life significantly.
