The map above illustrates the rate of deforestation from 1990-2000. Lighter pink/beige colors represent areas that have had little logging, whereas the darker red/maroon shaded areas embody terrains that have undergone heavy deforestation. This clearing of land is wiping Earth's forests on a massive scale, often resulting in damage to the quality of the land, as well as a contributor to habitat loss. Although forests cover 30% of the earth, large areas are being destroyed primarily in Brazil, as the map illustrates.
The United States, Canada, and eastern Europe are right behind Brazil in high rates of deforestation. Habitat loss is the #1 consequence from removing large forests, but other factors come into play as well. Removing trees deprives the forest of portions of its canopy, which
blocks the sun’s rays during the day and holds in heat at night. This
disruption leads to more extreme temperatures swings that can be harmful
to plants and animals.
"A more workable solution is to carefully manage forest resources by
eliminating clear-cutting to make sure that forest environments remain
intact. The cutting that does occur should be balanced by the planting
of enough young trees to replace the older ones felled in any given
forest. The number of new tree plantations is growing each year, but
their total still equals a tiny fraction of the Earth’s forested land" (www.enviornment.nationalgeographic.com).

This picture is very good at showing the amount of rainforest destruction. In the ten years displayed in this picture much of the forests have been affected. This has probably only gotten worse in the next 11 years. We really must take action to reduce and reverse the deforestation happening today.
ReplyDeleteYour artifact does is very clear in showing the environmental history of deforestation in the ten year span. The map shows that areas of rapid growth are prime examples of deforestation regions. It also shows that areas like the rainforest where resources are abundant are being striped heavily to meet the constant demand. Seeing how wide scale the issue is proves that something needs to be done before to much damage is inflicted.
ReplyDeleteDeforestation is certainly becoming a problem. Habitat destruction remains the number one cause of extinction and reduced biodiversity. Removing foliage from tropical rain forests is also highly destructive. Majority of the nutrients in a rainforest are held within the plants, not the soil. Therefore, when plants are removed, nutrients are lost and erosion becomes an issue.
