In 2015, the little Green information book detailed that the Nigerian populace is presented to elevated degrees of Particulate matter(PM) 2.5 which surpasses the ordinary norms/rules set by WHO at 94%, and it went further to express that 3% of kids under 5 years old experienced intense respiratory disease.
