Marine pollution is widely recognised as one of the four major threats to the world’s oceans, along with habitat destruction, over-exploitation of living marine resources and invasive marine species. Spills of oil and other chemicals into the marine environment, both from ships and land-based sources, is a significant source of pollution.

The biodiversity within the Solomon Island's geographical and political boundary are continuously under pressure from habitat destruction, overexploitation, waste, invasive species and climate change. Capacity constraints emanating from the absence of biodiversity values, institutional constraints, inadequate finance and the lack of scientific information are consequently undermining effort to lessen these pressures on biodiversity.

Invasive species are a major global threat to biodiversity and Pacific Islands are particularly vulnerable due to their isolation and relatively recent human occupation. Their native species often cannot cope with predation or competition from new arrivals. Niue already suffers from the impact of invasive species that have arrive in the country. However there are many more devastating species that are not present but found in other countries of the region and every effort needs to be made to prevent their arrivals.
