Environmental activists have expressed concern over reliance on firewood for cooking or heating in refugee camps. The issue, they contended, poses risk to both the environment and people's health.
The United Nations Environment Programme's 'Action on Air Quality' report launched during the second session of the United Nations Environment Assembly (UNEA) in Kenya in May, stated that air pollution- both indoor and outdoor- remains a major challenge in Africa.
"About 600,000 deaths occur every year across the continent are associated with this invisible killer. With 23 per cent of global deaths (12.6 million) linked to environmental factors, WHO (the World Health Organisation) estimates that air pollution is responsible for 7 million deaths every year, the report says.
