"According to the World Resources Institute (WRI), land use represents 61 percent of the country's greenhouse gas emissions. That means deforestation causes far more climate pollution than all of the country's cars and power plants combined. In fact, Indonesia has the world's highest rate of deforestation, even higher than Brazil, which contains most of the Amazon rainforest. From 2000 to 2012, according to research published in Nature, Indonesia lost more than 23,000 square miles of forest to logging, agriculture, and other uses. That's roughly the size of West Virginia. In 2010, the government attempted to put the brakes on deforestation by exchanging a two-year moratorium on new logging permits for $1 billion in aid from Norway and the United States. But according to Susan Minnemeyer, a forest analyst at the WRI, that policy appears to have had the "perverse impact of accelerating [deforestation], because those with permits felt that they had to take action quickly or they would no longer be able to." This all adds up to global-scale pollution: Indonesia is the world's fifth-ranking greenhouse gas emitter, coming in just behind Russia and India. In other words, we can't stop climate change without saving Indonesia's rainforests. Indonesia is in the middle of a public health crisis from forest fire haze. The problem isn't just deforestation, but how that deforestation is happening. In Indonesia, forests are often cleared out with fire. This can be done legally with a permit, but it's often carried out illegally as well. This year, forest fires are also being fueled by El Niño-related weather patterns. The combination of El Niño and intentional deforestation has proven incredibly dangerous: The country has experienced nearly 100,000 fires so far this year, the worst since the last major El Niño in 1997. Fire activity typically ramps up in September and October, the end of the dry season, and over the last couple of weeks the conflagrations have grown to crisis proportions—hence Joko's hasty return. The fires are so big they can be seen from space. The greenhouse impact from those fires is staggering: On several days over the last month, emissions from Indonesian forest fires have exceeded all emissions from the US economy: World Resources Institute To make matters worse, more than half of those fires occur on land made of peat, the thick, soil-like material made from decomposed plant matter. Peat is packed with carbon, and fires that occur on peatland can have a global warming impact 200 times greater than fires on normal soil, according to the WRI. Last week, Joko said the government would stop issuing new permits for commercial development on peatland, but that won't stop the fires that are already burning. Climate pollution is just part of the problem. Firefighting costs are pushing $50 million per week. The impact of this fire season on Indonesia's economy could reach $14 billion. And the thick blanket of haze that is stretching from the country across Southeast Asia has caused at least 10 deaths from haze-related illness and 500,000 cases of acute respiratory illness. Your snacks and makeup are part of the problem. Of course, Indonesians aren't just chopping and burning down trees for fun. Besides logging, one of the main uses for cleared land is to plant African oil palm, the fruits of which are used to produce palm oil. Palm oil is the world's most popular form of vegetable oil, and half of it comes from Indonesia. It's also found in about half the processed food you encounter in a grocery store (as well as many cosmetics). "
