Deforestation in Indonesia has been a massive environmental impact on the country, home to some of the most biologically diverse forests in the world, ranking third behind Brazil and the Democratic Republic of Congo. As late as 1900, Indonesia was still a densely forested country with the total forest representing 84 per cent of the total land area. Deforestation intensified in the 1970s and continuously accelerated since then. As a result, the estimated forest cover of 170 million ha around 1900 decreased to 98 million ha by the end of the 20th century, at least half of which is believed to be degraded by human activity. At present rates, tropical rainforests in Indonesia would be logged out in 10 years. Illegal share of all logging is ca 80% in Indonesia.
