Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to environmental pollution. Sri Lanka is also vulnerable to climate change impacts such as extreme weather events and sea level rise. [1]
It is also the primary threat to the survival of Sri Lanka's biodiversity. [2] Sri Lanka has 751 known species of amphibians, birds, mammals and reptiles of which 21.7% are endemic, and over 3314 species of vascular plants, of which 26.9% are endemic. [4]
Although this is a point source, due to the distributional nature, long-range transport, and multiple sources of the pollution, it can be considered as nonpoint source in the depositional area. Atmospheric inputs that affect runoff quality may come from dry deposition between storm events and wet deposition during storm events.
According to the U.N. FAO, 28.8% of Sri Lanka was forested in 2010 (about 1,86 million hectares). In 1995, it was 1.94 million hectares or 32.2% [11] of the land area that was classified as dense forests while the balance 0.47 million hectares or 7% the land area classified as open forests.
Sri Lanka is a small island nation with rich and various marine ecosystems. Thus, the inhabitants of Sri Lanka rely heavily on fisheries, with approximately a quarter of a million families make their living from fishing. [34] However, climate change in Sri Lanka can impact biodiversity offshore.
Effects of industrialisation and urbanisation on the biology and water quality of three lagoons in southern Sri Lanka viz. Rekawa, Dondra and Galle with reference to water pollution and upstream land uses.

In 2019 a total area of 16.5% [2] of Sri Lanka was forested. In 2010, it was 28.8% [3] (and 32.2% in 1995. [4]) 9.0% [5] of Sri Lanka's forests are classified as primary forest (the most biodiverse form of forest and the biggest carbon sinks on Earth). Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in ...
Plant diversity and endemism in Sri Lanka are quite high. Of 3,210 flowering plants belonging to 1,052 genera, 916 species and 18 genera are endemic. [3] All but one of Sri Lanka's more than 55 dipterocarp (Sinhalese "Hora") are found nowhere else in the world. Sri Lanka's amphibian diversity is only becoming known now.
