Marine Pollution: Causes, Impacts, and What’s Being Done in India

When you think of marine pollution, the contamination of oceans and seas by harmful substances, often from land-based activities. Also known as ocean pollution, it’s not just a distant problem—it’s washing up on India’s 7,500-kilometer coastline, killing fish, poisoning seafood, and hurting communities that depend on the sea. Every year, millions of tons of plastic, untreated sewage, agricultural runoff, and industrial waste flow into the Indian Ocean. It’s not just litter—it’s a systemic failure of waste management, regulation, and awareness.

This problem doesn’t exist in isolation. It’s tied to plastic waste, single-use plastics that don’t break down and instead fragment into microplastics, entering the food chain, and coastal ecosystems, vital habitats like mangroves, coral reefs, and seagrass beds that filter water, protect shorelines, and support marine life. These ecosystems are collapsing under pressure. In places like Mumbai, Kochi, and Visakhapatnam, fishermen report fewer catches. Tourists avoid beaches choked with trash. Even the Ganges, which flows into the Bay of Bengal, carries tons of untreated waste from cities hundreds of kilometers inland.

But it’s not all bad news. Scientists, NGOs, and local communities are stepping in. Researchers are tracking how microplastics move through fish and shellfish. Engineers are designing low-cost filters for coastal wastewater. Students are organizing beach cleanups that double as data collection drives. And policymakers are starting to enforce bans on single-use plastics—though implementation is uneven. What’s clear is that fixing marine pollution isn’t just about cleaning up. It’s about changing how we produce, use, and dispose of things we treat as disposable.

Below, you’ll find real stories and research from across India—on how pollution is measured, who’s affected most, and what solutions are actually working. No theory. No fluff. Just what’s happening on the ground, in the water, and in the labs.
