The Environmental World Wall Map from Global Mapping, 123 x 94cm (4ft x 3ft 1” approx.) & with laminated surface, showing a physical world map annotated with various environmental problems, with additional panels on deforestation, urbanization, land degradation, climate influences, etc. The main map shows the land masses with altitude colouring & relief shading to show the geography: mountain ranges, deserts, etc. Country names & boundaries are marked, plus a selection of cities, with those most polluted indicated by a special symbol. Other symbols indicate various environmental issues grouped into three types: man-made pollution (nuclear test sites & accidents, oil spills, etc), natural phenomena (deforestation, desertification, droughts, etc) & environmental impacts (pollution black spots, coral bleaching, areas affected by acid rain, etc). Panels under the map provided world maps dealing with deforestation, urbanization, land degradation & climate influences. Another panel shows the environmental changes in the Arctic. Also included are lists of worst oil spills & areas with worst air pollution, plus notes on acid rain & environmental hotspots.*LAMINATED & ENCAPSULATED WALL MAPS:** Laminated* wall maps have a thin layer of plastic usually applied to the printed side only. They can be written on with suitable marker pens without any damage to the map but, unless laminated on both sides, they are not damp-proof.* Encapsulated* wall maps are sealed between two sheets of plastic. They are more rigid & heavier than laminated maps of the same size. They are damp-proof & do not crinkle in humid conditions. Encapsulation gives the map a shiny surface, similar to being displayed behind glass. Many publishers & retailers often use these two terms interchangeably. Our map titles & descriptions follow the definitions provided above.
