The Ganga might have stood witness to many stages of India’s civilisation, as Mahatma Gandhi once noted, but in recent decades it has become a conduit for sewage, solid waste, industrial effluents and other pollutants.
1. A new study by an NGO has found evidence of a modern-day scourge, microplastics, in the river, with the highest concentrations in Varanasi and Kanpur, followed by Haridwar.
2. What the data show is the alarming presence of plastic filaments, fibres, fragments, and in two places, microbeads, with their composition pointing to both industrial and secondary broken-down plastics from articles of everyday use.
3. These range from tyres, clothing, food packaging, bags, cosmetics with microbeads, garland covers and other municipal waste.
4. The finding of significant levels of microscopic particles invisible to the naked eye at below 300 micrometres to 5 millimetres in the country’s holiest river calls into question the progress of two high-priority, well-funded missions of the government, Swachh Bharat, to deal with solid waste, and Namami Gange, to rid the river of its pollution.
5. Microplastics, recorded in recent times in the remotest of places — Mount Everest, Arctic snow, Icelandic glaciers, the French Pyrenees, and the depths of the Mariana Trench, among others — pose a hazard as plastics production outpaces the ability of governments to collect and manage waste.
6. Successive governments issued waste management rules, but dropped the ball on implementation.
7. Although the Centre recently issued a draft to tighten the Plastic Waste Management Rules, cities have failed to implement existing rules as well as the Solid Waste Management rules,
- on ending single-use plastics,
- waste segregation,
- recycling labels on packaging,
- extended producer responsibility for manufacturers and
- recovery of materials. Moreover,
Growing plastic waste will far exceed the capacity of governments to manage it, given that recycling has its limits. Swachh Bharat, therefore, must mean not merely keeping waste out of sight, achieved through costly dumping contracts, but sharply reduced generation, full segregation and recycling.
Plastic waste around the world is threatening the food web and the crisis demands a new global treaty modelled on the Montreal Protocol and the Paris Agreement. India needs to demonstrate that it is serious about a clean-up at home.

Darknet
Definition:
Darknet, also known as dark web or darknet market, refers to the part of the internet that is not indexed or accessible through traditional search engines. It is a network of private and encrypted websites that cannot be accessed through regular web browsers and requires special software and configuration to access.
The darknet is often associated with illegal activities such as drug trafficking, weapon sales, and hacking services, although not all sites on the darknet are illegal.
Examples:
Examples of darknet markets include Silk Road, AlphaBay, and Dream Market, which were all shut down by law enforcement agencies in recent years.
These marketplaces operate similarly to e-commerce websites, with vendors selling various illegal goods and services, such as drugs, counterfeit documents, and hacking tools, and buyers paying with cryptocurrency for their purchases.
