Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests—which leads to further deforestation. Forests are also cut as a result of growing urban sprawl as land is developed for dwellings.
Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees.
Yes, logging when strategically planned and excuted can be sustainable, but as you rightly identified most operations are illegal.
However, through education and support, we can get the illegal loggers to adopt sustainable logging practices.
On the natural disasters, we could adopt afforestation strategies to combat the identified deforestation agents. Thanks @izuchukwu1506
