At current rates of forest lost, the rainforests will likely disappear within a generation. Over 80% of Sarawak has been cleared, and this clearing has caused animals traditionally in lowland forest to retreat into the upland rain forests inland. Logging and cultivation practices have devastated tree cover, causing severe environmental degradation in the country. Floods in East Malaysia have been worsened by the loss of trees, and over 60% of the peninsula's forest has been cleared. With current rates of deforestation, the forests are predicted to be extinct by 2020. From 2000 to 2019, Sabah lost 1.60Mha, or 24%, of its tree cover. 51% of this loss came from Tongod, Beluran, Tawau, and Kinabatangan. In the same period, Sarawak lost 2.96Mha or 25% of its tree cover. Together, they made up 56% of Malaysia's 8.12Mha (28%) loss in tree cover during that period.
