In most situations, only 15% of the wood is used, the rest left to rot. Sometimes "just" the financially important trees are "extracted" - some trees are over 1000 years old (not unusual for e.g. Brazil Nuts) are felled. In cloud forests some trees do not grow at all for years so their age is unestimable. They still make good charcoal.
Palm oil is ecologically sound? Thousands of square kilometers of rainforest are felled to make way for plantations. Rivers are totally polluted with the waste products. Beef & pork production is mostly reliant on soya bean plantations - also on land where the rainforest was clear-felled.
