Forest and Ecosystem

Forests play the important role in natural and ecological stabilization. Alteration in present climate condition has a major impact to ecological system as a whole. Prediction of year 2020 (B.E. 2593) shows the exceed level of CO2 release comparing with the offset level from the global forests and ecosystems.

Rising in global surface temperature directly affects all organisms regarding plants and migration of some animal species to the cooler region. In the temperate region; animals, plants, and tress can relocate or migrate themselves with the distance of 25 – 40 kilometers per century. However, increasing of 3 degrees Celsius in the recent hundreds years may consequently cause the longer distance of organisms’ migration to more than hundreds kilometers.

Significant surge of CO2 level and other climate change factors have direct impacts on degradation of forest and species’ extinction. For instance, the forecasted outcomes of Amazon forest stated as 43 percent of 193 representative species will extinct in B.E. 2638; climate change will directly affect the animals and trees habitats; global warm will negatively affect the frequency of wildfire; less agricultural productivity; drought; storm; wildfire; rapid spreading of insects; and direct effects on millions’ households especially for the poverty.
