Imagine that two forests are surveyed for plant diversity. Researchers record 42 species in Forest A and 58 species in Forest B. At first glance, Forest B appears more diverse—but Forest A was surveyed using 20 quadrats, while Forest B was surveyed using 50. The difference could reflect real ecological variation, greater sampling effort, or … Continue reading Species Accumulation Curves and Rarefaction: How to Compare Biodiversity Samples Fairly
Two habitats can contain the same number of species and still differ greatly in biodiversity. One may contain similar numbers of individuals from every species, while the other may be dominated by only one species. This is the central difference between species richness and species diversity. Species richness records how many species are present. Species … Continue reading Species Richness vs Species Diversity: Differences, Examples and How to Measure Them
AI may appear entirely digital, but every response depends on data centers, electricity and cooling. This article examines how much water AI uses, why estimates differ and whether the growing water footprint should concern us.
Extreme heat, flooding and water scarcity are beginning to affect the same cities. This article examines whether urban areas are becoming unlivable and what effective climate adaptation would require.
India is experiencing severe floods and landslides even though seasonal monsoon rainfall remains below normal in many regions. Here is how extreme rainfall, urbanisation and uneven rain distribution explain the contradiction.
Why has rainfall suddenly reduced across parts of India in July 2026? Learn what a monsoon break is, what causes it and how it affects farming, water and heat.
Heavy monsoon rainfall can trigger floods, landslides and urban waterlogging when rainwater exceeds the capacity of soil, rivers, slopes and drainage systems. This article explains the environmental science behind extreme rainfall, runoff, soil saturation and climate risk in India.
Explore the top sustainability trends in 2026, including climate adaptation, AI data centers, water risk, biodiversity loss, supply chains and sustainable finance.
Learn the difference between tree planting and ecological restoration, why planting trees is not always enough, and how real ecosystem recovery works.
Discover how climate change, biodiversity and ecosystems are interconnected and why protecting nature is essential for climate resilience and sustainability.
