trees absorb contaminants. However, their extent is decreas-
ing in tropical areas because of human population growth and
urbanization along coastlines, conversion of mangrove swamps
to shrimp farms, and the use of their wood for fuel. Without
the dense network of vegetation provided by the mangrove
trees, sediments loaded with pollutants can enter lagoons and
estuaries, which are sites of biodiversity and major sources of
income for local populations through fishing and aquaculture.
