India tops list of pollution-linked deaths: Study

According to new study published in medical journal The Lancet, India has topped list of countries with pollution-related deaths in 2015.

In India, 2.51 million people died prematurely in 2015 due to diseases linked to air, water and other forms of pollution. Of the 2.51 million deaths in India, 1.81 million were related to air pollution, 0.64 million to water pollution, 0.17 million to occupational exposure and 95,000 linked to lead pollution

Key Facts

Globally, air pollution was biggest contributor linked to 6.5 million deaths in 2015, ahead of water pollution (1.8 million) and workplace-related pollution (0.8 million).

Most of the pollution-related deaths — 92%— were reported in low and middle income countries, and in rapidly industrialising nations such as India, China, Pakistan, Bangladesh, Madagascar and Kenya. China, with 1.8 million pollution-linked deaths in 2015, followed India.  Most of these deaths were due to non-communicable diseases caused by pollution, such as heart disease, stroke, lung cancer and chronic obstructive pulmonary disease (COPD).

India accounted for about 28% of an estimated 9 million pollution-linked deaths worldwide in 2015 and topped list of deaths linked to polluted air (1.81 million) and water (0.64 million).

China (1.58 million) was placed after India in deaths linked to air-pollution, followed by Pakistan (0.22 million), Bangladesh (0.21 million) and Russia (0.14 million). In deaths linked to water pollution, Nigeria (0.16 million) and Pakistan (74,000) were placed after India.

The Lancet study concluded that pollution is now largest environmental cause of disease and death globally — three times more those from HIV-AIDS, TB and malaria put together. It also found that pollution from outdoor and indoor air, water and soil contamination, and chemical pollutants was one of largest risk factors leading to premature death.


For the study, researchers had used data from Global Burden of Disease study, which brings together comprehensive estimates on effects of pollution on health, provides economic costs, and reveals the extent of contaminated sites across world for first time. Its aim was to raise global awareness on pollution, end neglect of pollution-related diseases, and mobilise resources and political will to effectively confront pollution.


Sawfish more threatened than tigers: Scientists

Scientists on World Sawfish Day (observed on October 17th) announced that sawfish, sighted off Indian coast less than 10 times in over a decade appears to be more threatened than tigers and elephants

Anecdotal evidence suggested that sawfish was once common along the Indian coast but today it may be the most endangered fish species in India.

Key Facts

Sawfish also known as carpenter sharks are a family of rays. They are characterized by long, narrow, flattened rostrum or nose extension, lined with sharp transverse teeth resembling saw.Sawfish are closely related to sharks and have shark-shaped bodies, hence, they are also called flat sharks.

They are elasmobranchs meaning their skeleton is made of cartilage. There are only five species of sawfish ever identified —knifetooth sawfish, smalltooth sawfish, dwarf sawfish largetooth sawfish and green sawfish.

Protection Status: In the International Union for Conservation of Nature Global Red List, sawfish family has been assessed either ‘Endangered’ or ‘Critically Endangered’ considering their threatened status, high extinction risk and observed population decline. The sawfish has been given high degree of protection as it is listed in Schedule I of the Indian Wildlife (Protection) Act 1972 enacted to save them from exploitation.
