Which factor is likely responsible for the changes observed in the worlds rainforest

The answer is human activity. The cause of changes comes from human activities, which, not like natural damage, are relentless and exhaustive. Although most of this deforestation is compelled by national and international economic forces, a major proportion serves no long-term purpose; it results from sustenance activities on a local level. Many of the effects from human-induced annihilation of the rainforests are probably permanent within our time. The part of humans in the deforestation of the world's forests is significant and extensive. Many activities contribute to this loss as well as sustenance activities, logging, oil extraction, fires, mining, war, commercial agriculture, cattle ranching, hydroelectric projects, pollution, hunting and poaching, the collection of fuel wood and building material, and road construction.
