What are the of slash and burn?

Answer 1

Slash and burn occurs when virgin forest is cleared so people can grow crops in the clearing so formed. In the short term, crops will usually grow well, but eventually the nutrients are soon used up, and crop yields quickly fall. So the clearing is abandoned, and secondary nature growth results in shrubby growth. Having abandoned the clearing, slash and burn happens somewhere else, so it damages the virgin forest in the long term. There is no advantage in slash and burn, unless you don't care about our environment!
