Almost one in seven children worldwide, most of whom are in South Asia, live in places where they are exposed to high levels of outdoor air pollution, the United Nation's children's agency UNICEF revealed on Monday.

The Conference of Parties is a part of the United Nations Framework Convention on Climate Change (UNFCCC) entered into force in 1994, aimed at reducing greenhouse gas concentrations in the atmosphere.

Together, outdoor and indoor air pollution are directly linked to pneumonia and other respiratory diseases that account for almost one death in 10 in children under the age of five, or nearly 600,000 children, making air pollution a leading danger to children's health, UNICEF said.

NewsGram brings to you current foreign news from all over the world. "Delhi's air remains so polluted throughout the year that it doesn't really have room for additional pollution during Diwali", Roychowdhury tells The Guardian.

But in New Delhi, the capital of India, the alarming numbers are hardly a surprise.

World Health Organization studies also claim that one in ten deaths of children under five is linked to air pollution. "Children are our future and we must do all in our power to protect them", Bengt said.

In South East Asia, satellite data showed the worst-affected areas were Laos, northern Thailand and China near Shanghai.

Improve air quality by cutting back on fossil fuel combustion and investing more on energy efficient sources.

There was a rapid build-up of various pollutants in Delhi's air on Sunday evening as bursting of firecrackers spiked the pollution.

About 300 million children in the world breathe highly toxic air, Unicef said in a report to be released Monday that used satellite imagery to illustrate the magnitude of the problem.

According to the Unicef report, earlier studies have indicated a relation with high air pollution and miscarriage, low birth rate, and children's cognitive function.

UNICEF defines high outdoor pollution as measuring six times as much as set in the World Health Organization's worldwide guidelines, Reuters reports.

It is also worth mentioning that children have small airways and more permeable respiratory tracts, so they are more likely to suffer blockages or develop infections, as their immune system hasn't fully developed.

Unicef warned the levels of global air pollution contributed to 600,000 child deaths a year - more than are caused by malaria and HIV/Aids combined.

Youngsters also breathe faster than adults and take in more air relative to their body weight. Countries will be called upon to take action to reduce air pollution.

Of the two billion children in the world who live in areas with toxic air levels, about a third of them live in north India and neighbouring countries.

Minimize children's exposure to air pollution by keeping schools away from factories and other pollution sources and using cleaner cookstoves in homes.
