Transcript of deforestation

Current status >>>Brazil has extensive Savannah and brush; Indonesia has many dry islands; Kenya and Tanzania have only small patches of rain forest. Forest fires WHAT ARE THE EFFECTS??? what can we do about it?? In late 1997, The Philippines: -The islands that make up the Philippines used to be all forested. Today only 35% of those forests remain; the only (slightly) good news in that is about 28% remain as frontier forest. But with a deforestation rate over the past twenty or so years of 26%, the future isn't so bright.

****the current deforestation rate is around 2 percent per year Wildlife sanctuaries Industrialization & Conversion
to human settlement Deforestation the term which
refers to
irresponsible
cutting down
of trees in
forested areas WHAT ARE THE CAUSES????? Logging—both legal and illegal Shifting cultivation(kaingin system) Overgrazing *SOIL EROSION
*GLOBAL WARMING
*DISRUPTION OF THE WATER CYCLE
*LOSS OF BIODIVERSITY
*CLIMATE CHANGE
*FLOODING
*DROUGHT Sample Effect of Deforestation Typhoon Sendong at CAGAYAN DE ORO Nasa Deforestation Image Spanish arrived in the Philippines in the 16th century scattered coastal areas had been
cleared for agriculture and villages LITTLE HISTORY >>>A few hundred years ago, at least 95 percent of the Philippines was covered by rain forest; only a few patches of open woodland and seasonal forest BUT At the end of more than 300 years of Spanish colonial rule, rain forest still covered about 70 percent of the Philippines. Some islands had been heavily deforested, while others remained nearly untouched. Cebu was so badly deforested; Bohol and Panay had less than half of their original forest much of the highland rain forest remained intact having the highest density of both unique and endangered species in the world, its decline in old-growth forest from 70 percent to seven percent in less than a century is probably the most rapid and severe in the world.......:((((

Philippines Forest Figures (2010) Only about 5 percent of the Philippines land area is under some form of protection.  Over the past century, the islands that make up the Philippines have lost nearly three-quarters of their mangrove forests. 
The current rate of mangrove deforestation ranges from 2,000 to 3,000 hectares per year. 
Reforestation Commercial forest plantations thank you!!!!!!!!
