Beware For Deforestation Effects

Deforestation gives a bad effect on the world climate and temperature change in the world. There are natural and anthropogenic factors can cause deforentation. Natural factors that can cause changes in forests over time including insects, forest fires, diseases, weather, competition between species, etc. Anthropogenic factors that can disturb forests include logging beyond a tolerable limit, urban sprawl, human-caused forest fires, invasive species with exsotic species, and the slash-burn practices of shifting cultivation. However, the loss and re-growth of forest leads to a distinction between two types of forest; primary or old-growth forest and secondary forest. 

Actually, forest includes in renuwable resources which is can be sustainable if there is well management of forest product. On the other side, the way to manage forest product did not follow what supposed to do. Nowdays, it is difficult finding forest-primary because of human activity which is not care and respect to our forest. Illegal logging becomes serious problem as time goes on. It needs serious handling because it gets in touch with crime. The rising of human necessities influence land-changing alterations. Forest plantations, coconut palm plantations, and mining activity in protection forest area become main affect of sustainable forest. Forest plantation, generally intended for the production of pulpwood and timber that increase the total area of forest worldwide. Actually, high-heterogeneous forest better than mono-specific condition or homogeneous which is heterogeneity influence the stabilization of forest. Most of people burn the forest to do land-clearing activity. However, it will be danger to our environment because of the smoke that contains damage gases. There are many mining activities in protection forest area that suppose forbidden for exploration activity.

Deforestation problem related with our best environment issue that is global warming. The disturbance of forest reduces the earth natural ability to absorb damage gasses. Accumulating damage gasses or pollution gasses in atmosphere that caused by human activity and deforestation activity can break ozone surface. There are kinds of damage gases such as: CO2, CO, CFC, SF6, CH4, etc.  Day by day, our earth becomes warm, there is an extreme weather condition, higher level of sea, changing pattern of precipitation, and melting of glaciers, species extinction, disturbing food webs, coastal flooding, increasing disease vectors. With these related great bad effects of deforestation, there have been many issues considering the responsibilities that we should be taken up against global warming. A major impact on global warming is the agreement of Kyoto Protocol, an environment committee, on December 1997 by many nations. The main objective of Kyoto Protocol is to reduce the emission of greenhouse gasses.
