Since animals require the special habitats for survival,the destruction or modification of habitats lead to the loss of shelters and food sources of the animals.This has a devastating impact on bio diversity and many species will be pushed towards extinction.
Trees are removed The nutrients can’t be locked up and loss The entire ecosystem is affected by the disruptive effects on nutrient availability
No roots of trees hold the topsoil The topsoil is washed away by heavy rain or blown by strong wind The nutrient of soil loss The exposed soil become infertile and abandoned & soil erosion occur
As forests are destroyed, human communities lose vital services such as protecting the soil, maintaining productive water cycles, and mediating both floods and drought at a local and a regional level.
Forests is removed No evaporation of water through the leaves and amount of carbon dioxide increase The air can’t be cool down and moistened The condition become hotter and drier Global warming
Ten thousands years ago,about half of the world’s land surface was covered in trees. About a third of these forests have completely disappeared today. The extent of global tropical deforestation through the 1980’s was estimated to be 16.9millon hectares a year. This means that an area of half the total size of Hong Kong is lost every day. Over 40% of all tropical forests have been destroyed in the last 50 years.
