Geography of the European Netherlands Geography of the European Netherlands The geography of the Netherlands in Europe is unusual in that much of its land has been reclaimed from the sea and is below sea level, protected by dikes. Another factor that has influenced its physical appearance is that the country is among the most densely populated on Earth. It is ranked 30th overall on that scale, but is behind only three countries having a population over 16 million. Consequently, the Netherlands is highly urbanized. Geographic coordinates: 5.45°E and 50.30°N The Dutch RD coordinate system ("Rijksdriehoeksmeting") is also in common use; see (pdf, in Dutch;
Environmental issues in the Niger Delta Niger Delta. Vegetation in the Niger River Delta consists of extensive mangrove forests, brackish swamp forests, and rainforests. The large expanses of mangrove forests are estimated to cover approximately 5,000 to 8,580 km² of land. Mangroves remain very important to the indigenous people of Nigeria as well as to the various organisms that inhabit these ecosystems. Human impact from poor land management upstream coupled with the constant pollution of petroleum has caused five to ten percent of these mangrove forests to disappear. The volatile, quickly penetrating, and viscous properties of petroleum have wiped out large areas of vegetation. When spills
