According to the Air Quality Life Index (AQLI) 2025 report, air pollution has emerged as India’s most severe health threat, reducing the country’s average life expectancy by 3.5 years. The findings highlight the dire impact of air pollution on the health and well-being of millions of people across India.
The AQLI is a tool developed by Michael Greenstone and the Energy Policy Institute (EPIC) at the University of Chicago. It quantifies the impact of particulate air pollution (PM2.5) on life expectancy by combining long-term exposure data with global particulate pollution measurements. The AQLI helps to highlight the true cost of air pollution on communities worldwide and provides insights into the severe health consequences caused by air pollution.
Impact on India’s Life Expectancy:
Air pollution in India has reduced the average life expectancy by 3.5 years.
Toxic air pollution is responsible for more years of lost life in India than childhood and maternal malnutrition, and unsafe water, sanitation, and handwashing combined.
Pollution Levels Across India:
All 1.4 billion Indians live in areas where pollution levels exceed the World Health Organization’s (WHO) safe limit of 5 µg/m³ for PM2.5.
The northern belt of India remains the world’s most polluted zone, with 544.4 million people (38.9% of India’s population) living under severe air pollution.
Most Affected Regions:
Delhi-NCR is the worst-hit region, where residents face a loss of 8.2 years of life expectancy (based on WHO’s standards for air quality). Even with India’s own weaker PM2.5 standard of 40 µg/m³, residents of Delhi-NCR still lose 4.74 years of life expectancy.
Other severely affected states include:
Bihar: 5.6 years lost
Haryana: 5.3 years lost
Uttar Pradesh: 5 years lost
Potential Gains in Life Expectancy:
If air pollution levels were reduced to India's PM2.5 standard of 40 µg/m³, Indians could gain an average of 1.5 years in life expectancy.
Reducing pollution to meet WHO’s stricter guideline of 5 µg/m³ could add up to 9.4 months to life expectancy, even in cleaner regions.
Regional Trends:
South Asia is identified as the most polluted region globally, with PM2.5 concentrations rising by 2.8% in 2023 after a brief dip in 2022.
Air pollution across South Asia reduces life expectancy by an average of 3 years, with the most affected areas losing more than 8 years of life expectancy.
The report highlights the public health crisis created by air pollution, stressing the need for more stringent regulations and greater investment in reducing pollution levels.
It underscores the health inequities faced by people living in the most polluted areas, particularly in the north and east of India.
These findings support the growing calls for improving air quality standards, stricter enforcement of pollution norms, and widespread public health awareness.
The AQLI 2025 report paints a grim picture of air pollution’s toll on India's public health, pointing to a significant reduction in life expectancy. It emphasizes the need for urgent action to mitigate pollution, improve air quality, and ultimately increase the life expectancy of millions of Indians. The findings call for a collaborative approach involving government action, policy reforms, and individual participation to combat this growing environmental threat
The Tirupati Urban Development Authority (TUDA) has launched Operation SWARNA, a large-scale initiative aimed at rescuing the Swarnamukhi River from encroachment and land grabbers. The mission focuses on reviving its flow, rejuvenating its ecosystem, and ensuring the long-term sustainability of the river.
The Swarnamukhi River is a vital river in Andhra Pradesh, India. It holds cultural, religious, and ecological significance, especially as it flows through the sacred regions of Tirumala and Srikalahasti.
Location: The Swarnamukhi originates in the Eastern Ghats near Pakala village, in Chittoor district, Andhra Pradesh, at an elevation of 300 meters.

Length: The river stretches for a total of 130 kilometers.
Catchment Area: The river basin covers a catchment area of 3,225 sq.km.
The Swarnamukhi River is an independent river system, meaning it doesn't receive water from any major river networks.
Its flow largely depends on rainfall, especially in its upper catchment areas.
The river is heavily influenced by seasonal variations, with average rainfall decreasing from 1,270 mm at the eastern end to 762 mm at the western end of the basin.
The Kalyani River is its main tributary, and the Kalyani Dam was constructed in 1977 across this tributary to regulate water flow.
Religious Importance: The Swarnamukhi river holds immense religious value, especially for devotees visiting the Tirumala Venkateswara Temple and the Srikalahasteeswara Temple. These temples are major pilgrimage destinations for Hindus, making the river an important cultural landmark.
Ecological Importance: The river supports diverse ecosystems along its course, particularly in its flowing through hilly and rural landscapes.
Dependence on Rainfall: As an independent river system, the Swarnamukhi’s flow is vulnerable to changes in rainfall patterns, making its preservation critical for the local environment and agriculture.
The TUDA's Operation SWARNA aims to address several challenges faced by the Swarnamukhi River:
Combat Land Encroachment: The river has faced significant land grabbing, especially in its course through urban and rural areas. Operation SWARNA will work towards protecting and restoring its riverbed by evicting illegal land occupations.
Reviving the River’s Flow Area: The initiative will focus on revitalizing the areas where the river's flow is obstructed or diverted due to encroachments. This could include removing dumped waste, re-establishing natural channels, and managing the riverbanks.
Water Quality & Ecosystem Rejuvenation: By focusing on river rejuvenation, the operation aims to improve the river's water quality, allowing it to support local wildlife, and better serve the agricultural needs of nearby communities.
Sustenance of the River: With a focus on long-term sustainability, the operation will also implement measures to ensure the continued flow of water in the river during dry periods, possibly through infrastructure projects such as rainwater harvesting, watershed management, and the creation of more water storage facilities.
The Swarnamukhi River is an integral part of Andhra Pradesh’s geography and culture, and Operation SWARNA represents a concerted effort to protect and preserve this valuable natural resource. By combating land encroachment, revitalizing its flow area, and promoting sustainability, the initiative aims to secure the future of the river, benefiting the local communities, the environment, and cultural heritage of the region

A new study has revealed a fascinating behavioral observation about killer whales (also known as orcas): they may be exploring human behavior by offering whole prey to humans and waiting for a response. This unique interaction suggests that orcas might be trying to understand human reactions or even engage in a form of social exploration.
Scientific Name: Orcinus orca
Family: Delphinidae (Dolphins)
Killer whales, or orcas, are top predators in the ocean and hold the title of being the largest member of the dolphin family. Despite being called "whales," they are actually the largest species of dolphins.
Distribution:
Orcas are the most widely distributed cetaceans, found in all oceans, from the Arctic and Antarctic to tropical seas.
Appearance:
Orcas are easily recognizable by their striking black and white coloration, with black dorsal fins and white patches near their eyes and bellies.
Behavior:
Orcas are highly social and typically live in pods—maternally related groups that can vary in size from just a few individuals to over 30.
They are known for their complex and sophisticated communication systems, using underwater sound to communicate, navigate, and hunt.
Orcas have been observed demonstrating cultural behaviors, like teaching their young unique hunting techniques or vocalizations.
Hunting and Feeding:
As apex predators, orcas are capable of hunting a wide range of prey, from fish and squid to marine mammals such as seals, whales, and even sharks. Their intelligence and team-oriented hunting tactics make them formidable predators.
Habitat:
Orcas are found in a variety of environments, ranging from coastal waters to deep oceanic habitats. They are adaptive and can live in both colder and warmer regions of the world.
Threats:
While orcas are apex predators, they are not without threats. Entanglement in fishing gear is one of the most significant risks they face.
Habitat degradation due to pollution and the loss of prey species also poses a threat to orca populations.
Conservation Status:
The IUCN Red List has classified killer whales as Data Deficient, meaning there isn’t enough information available to assess their overall population trends or specific conservation needs.
Killer whales are not only fascinating for their role as apex predators but also for their complex social behaviors and intelligence. The discovery of them potentially interacting with humans by offering prey further underscores their remarkable adaptability and cognitive abilities.
As top predators, they play a critical role in the health of marine ecosystems. However, they face numerous challenges from human activities, including entanglement in fishing gear and habitat destruction, which threaten their populations.
