Why is "Air pollution in Colombia" trending?

Wikipedia Overview

Environmentally, Colombia is a mega-diverse country from its natural land terrain to its biological wildlife. Its biodiversity is a result of its geographical location and elevation. It is the fourth largest South American country and only country in South America to have coasts on the Pacific and Caribbean Sea. Colombia's terrain can be divided into six main natural zones: The Caribbean, the Pacific, The Orinoco region, The Amazonia region, the Andean region, and the Insular region. 52.2% of the environment is predominately the Andes, Amazon, and Pacific Basins, followed by the Orinoco basin 13.9%, the Andes and the Caribbean. The Tropical Andes, Choco, and the Caribbean are considered biodiversity hotspots which puts these areas at high risk of concentration of colonizing activities. Colombia host over 1800 bird species and at least one new species are detected every year. Decades of civil war and political unrest have impeded biological and environmental research in Colombia. The political unrest in Colombia catalyzes the alteration of land patterns through the cultivation of coca and opium crops, the redirection of extractive activities, and land abandonment in some areas.
