Status of terrestrial ecoregions - threats and vulnerabilities
In a World Wildlife Fund for Nature (WWF) study, experts identified 200 periority terrestrial ecoregions - defined as large scale ecological systems with characteristic flora, fauna and climate with high priority for conservation. Furthermore, as presented in this map, the 200 ecoregions were ranked based on their current and future threats and conservation status. From the study - 47% of the terrestrial ecorgions are considered critical or endan...

Coastal areas with high population densities are those with the most shoreline degradation or alteration. Densely populated areas close to seas are also the most attractive for a lot of economic activity. The graphic shows the proportion of the population that lives within 100 km of the coast, for each of the world's nations and where there are coastal zones with high degree of human alteration (compared to 'natural' landcover). In addition, the ...
