Ganges River: A Plastic Pollution Crisis

The Ganges River, considered to be one of the most polluted rivers in the world, is inundated with plastic waste. Flowing through northern India and Bangladesh, the river provides water resources to over half a billion people, or 40% of India's population. However, an estimated 6,000 tons of plastic waste exit the Ganges annually, threatening the region's water supply and endangering wildlife. The plastic waste in the Ganges includes discarded fishing gear, plastic packaging, disposable bottles, and cutlery, with polyethylene identified as the most abundant type of waste. Efforts to address this crisis, such as the National Geographic's Sea to Source: Ganges expedition, aim to raise awareness, educate, and find solutions to reduce plastic pollution.

The Ganges is the fifth most polluted river in the world

The Ganges River, formed by the confluence of the Bhagirathi and Alaknanda rivers in the western Himalayas, is considered the fifth most polluted river in the world. It is worshipped as "Ganga Mata", the divine mother responsible for sustaining life and nurturing civilization throughout India's history. Despite its cultural significance, the river faces a dire issue with plastic pollution, threatening both the environment and the health of those who depend on it.

The Ganges is a major artery, flowing across northern India and Bangladesh through one of the largest and most heavily populated river basins globally. This high population density contributes significantly to the river's pollution. Inadequate trash collection systems result in plastic waste being strewn across areas where monsoon rains wash it into the river. The city of Haridwar, regarded as holy in the Hindu religion, generates close to 11 tonnes of plastic waste daily, with this amount potentially doubling during festivals. Much of this waste is either directly dumped at the Ganges ghats or illegally discarded in vacant sites.

A recent study by the Wildlife Institute of India identified various plastic items, including discarded fishing gear such as nets, ropes, and lines, as well as single-use plastic products like bags, bottles, and cutlery. These items contain toxic materials like polyethylene, polypropylene, and polystyrene, which endanger aquatic life and turn the river into a toxic water body downstream. The Ganges and two nearby waterways are estimated to release up to three billion microplastic particles into the Indian Ocean each day.

The pollution in the Ganges has severe consequences for the millions of people who rely on it for their daily needs. It provides water resources for over half a billion people, approximately 40% of India's population. The contamination of the river with human waste, industrial contaminants, and microplastics poses significant health risks to those who depend on it for drinking, bathing, and religious practices.

Addressing the plastic pollution in the Ganges requires a multifaceted approach. It involves improving waste management systems, promoting recycling and proper disposal, and raising awareness about the environmental impact of littering. The National Geographic Society's "Sea to Source: Ganges" expedition aims to educate students about the impacts of plastic pollution and empower them to take action in their communities. By understanding the problem and taking collective action, there is still hope to mitigate the pollution in the Ganges and protect this vital waterway for future generations.

More than 6,000 tons of plastic waste flow into the river annually

The Ganges River is considered one of the most polluted rivers in the world, with an estimated 6,000 tons of plastic waste flowing into it annually. This waste includes polyethylene from discarded plastic bags, food packaging films, and milk bottles, as well as single-use plastic products like throw-away cutlery, plates, cups, and bottles. These items are difficult to recycle and decompose, persisting in landfills and flowing through sewers and rivers into the oceans, endangering various life forms.

The plastic waste in the Ganges is a complex issue with multiple sources. One significant contributor is the direct dumping of plastic waste into the river, particularly at the Ganges ghats (embankments on the banks of the Ganges where pilgrims bathe and offer prayers). Haridwar, a holy city in the Hindu religion, generates close to 11 tonnes of plastic waste as untreated waste and litter on a regular day, with this amount potentially doubling during festivals. Another source of plastic leakage is riverside slums, where garbage collection is inadequate, and plastic waste enters the river through open drains.

The CounterMEASURE project by the United Nations Environment Programme (UNEP) has identified 17 leakage hotspots in Haridwar, including vacant lots, slums with open drains, and sluice valves at barrages. Similarly, in the city of Agra, an estimated 10-30 tonnes of plastic waste from 9 hotspots make their way into the Yamuna River, a major tributary of the Ganges. The project has also been deployed in Prayagraj, where roughly eight tonnes of plastic litter per day are estimated to leak into land and riverine ecosystems, with almost 100 hotspots identified across the city.

The plastic waste in the Ganges is not just a local problem but also has far-reaching consequences. The Ganges and two nearby waterways are responsible for pumping up to three billion microplastic particles into the Indian Ocean each day. These microplastics, measuring less than 5 mm in size, can bind to harmful pollutants and metal nanoparticles, increasing their toxicity. The Ganges River Basin, with more than 655 million people relying on it as a water source, is described as the most populous river basin in the world.

The issue of plastic pollution in the Ganges is being addressed through various initiatives and research projects. The National Geographic Society sponsored a research expedition, "Sea to Source: Ganges," in 2019 to study the flow of plastic into the ocean and develop strategies to prevent plastic from reaching the ocean. The CounterMEASURE project by the United Nations Environment Programme (UNEP) aims to track and survey the leakage and movement of plastic waste in the Ganges and Mekong rivers. These efforts are crucial in mitigating the environmental impact of plastic pollution and protecting the river's delicate ecosystem.

Plastic waste in the Ganges is estimated to be 1000 billion pounds per year

The Ganges River is considered one of the most polluted rivers in the world. It is worshipped as "Ganga Mata", the divine mother responsible for nurturing and sustaining life and civilization in India. The river provides water for over 400 million people, or 40% of India's population. However, it is heavily contaminated with industrial runoff, untreated sewage, and household waste.

The high levels of plastic pollution in the Ganges are a result of a combination of factors. One significant factor is the lack of proper waste management and recycling infrastructure in the areas surrounding the river. It is estimated that 10-25% of plastic waste generated in these areas is littered and not routed through appropriate disposal channels. This litter accumulates in hotspots within and around cities, and during the rainy season, it is washed into the river. In addition, plastic waste is often directly dumped at the Ganges ghats, the embankments on the river banks where pilgrims bathe and offer prayers.

To address the plastic pollution in the Ganges, various initiatives have been undertaken. The CounterMEASURE project, funded by the United Nations Environment Programme (UNEP) and Japan, aims to track and survey plastic waste leakage and movement in the Ganges and Mekong rivers. The project has identified plastic accumulation and leakage hotspots in cities along the river, such as Haridwar, Agra, and Prayagraj. National Geographic has also sponsored research expeditions, including one in 2019 with a team of scientists, engineers, and staff from various countries, to study the extent of plastic pollution in the river and develop solutions.

Despite these efforts, the Ganges continues to be a highway of plastic waste, and the problem of plastic pollution in the river remains a pressing issue that requires further attention and action.

Plastic waste in the river includes polystyrene and polyethylene

The Ganges River is one of the most polluted rivers in the world. It is considered the fifth most polluted river, with an estimated 6,000 tons of plastic waste flowing out of it each year. The river provides water resources for over half a billion people, or 40% of India's population, and is worshipped as "Ganga Mata", the divine mother responsible for sustaining life and nurturing civilization throughout India's history. Unfortunately, an overwhelming amount of 1.2 billion pounds of plastics are dumped into the Ganges annually.

The plastic waste in the river includes polystyrene and polyethylene. Polyethylene, in particular, is the most abundant type of waste found in the river. It comes from discarded plastic bags, food packaging films, and milk bottles, which are difficult to recycle and decompose. These single-use plastic products persist in landfills and flow through sewers and rivers, endangering various life forms. The accumulation of polyethylene in the Ganges turns the river into a toxic water body downstream.

In addition to polyethylene, polystyrene is also present in the river as a result of waste plastic materials. Polystyrene is commonly found in fishing gear, such as nets, ropes, strings, and lines. These discarded pieces of fishing equipment pose a significant threat to the Gangetic river dolphins, turtles, frogs, and birds.

The presence of these plastic pollutants in the Ganges River is a pressing issue that requires attention and action. The high levels of plastic waste not only endanger the environment but also impact the millions of people who depend on the river for their daily needs.

The plastic waste in the river is a threat to wildlife

The Ganges River, considered to be the fifth or sixth most polluted river in the world, is worshipped as "Ganga Mata", the divine mother responsible for sustaining life and nurturing civilization throughout India's history. It is relied on as a water source for roughly 400 million people, or 40% of India's population. Despite this, an overwhelming amount of 1.2 billion pounds of plastics are still dumped into the river annually.

Secondly, plastic waste can indirectly affect wildlife by impacting the aquatic ecosystem. Microplastics can alter the properties of the ecosystem, leading to the death of fish, birds, and marine mammals. The accumulation of plastic waste can also disrupt the natural habitats of various species, hindering their ability to feed, breed, and shelter. This disruption can have cascading effects on the entire food web, potentially leading to population declines or even local extinctions.

Furthermore, plastic waste in the Ganges River is not limited to the river itself but also extends to its tributaries and surrounding areas. The Yamuna River, a major tributary, receives an estimated 10–30 tonnes of plastic waste from the city of Agra alone. This waste often originates from riverside slums with poor garbage collection systems, where plastic enters the river through open drains. The plastic debris also comes from the industrial sector, with contributions from the footwear industry in the form of synthetic leather and rubber trimmings.

The plastic pollution in the Ganges River and its tributaries is a pressing issue that requires urgent attention. The impact of this pollution on wildlife is evident, and the threat to the delicate balance of the ecosystem is imminent. Comprehensive measures, including improved waste management systems, increased recycling initiatives, and stricter regulations, are necessary to mitigate the threat that plastic waste poses to the wildlife dependent on the Ganges River and its surrounding habitats.
