Logging, along with cultivation practices has devastated tree cover, causing severe environmental degradation in the country. Over 80 per cent of Sarawak's rainforest has been logged. Floods in East Malaysia have been worsened by the loss of trees, and over 60 per cent of the Peninsula's forest have been cleared. With current rates of deforestation, mainly for the palm oil industry, the forests are predicted to be extinct by 2020. Deforestation is a major problem for animals, fungi and plants, having caused species such as ''Begonia eiromischa'' to go extinct. Most remaining forest is found inside reserves and national parks. Habitat destruction has proved a threat for marine life. Illegal fishing is another major threat, with fishing methods such as dynamite fishing and poisoning depleting marine ecosystems. Leatherback turtle numbers have dropped 98 per cent since the 1950s. Hunting has also been an issue for some animals, with overconsumption and the use of animal parts for profit endangering many animals, from marine life to tigers. Marine life is also detrimentally affected by uncontrolled tourism.
