The "Haze" in Southeast Asia during 1997 was the result of extensive fires burning unchecked through drought-stricken forests. In Indonesia alone, an area at least the size of New Jersey was burned.
Deforestation for wood and agricultural land can provide numerous economic benefits. These include development, commercial farming and selling wood for industrious use. This can have many damaging environmental impacts and can harshly affect local and regional climate.
Forests absorb a lot of sunlight for photosynthesis, and only about 12 - 15% is reflected. The large amounts of energy absorbed by fo...
