Why Rainforests Are Being Destroyed and What’s at Stake

Rainforests are being destroyed primarily to make room for agriculture. Over the past two decades, permanent agriculture has accounted for nearly 60% of tropical primary forest loss, with cattle ranching and commodity crops like palm oil and soy leading the way. But the picture is more complex than farming alone: logging, mining, infrastructure development, and wildfire (increasingly worsened by climate change) all play significant roles, and government subsidies worth trillions of dollars continue to fund the industries doing the clearing.

Agriculture Is the Biggest Driver

Between 2002 and 2024, permanent agriculture was responsible for 59.7% of tropical primary forest loss worldwide. The single largest culprit within that category is beef. Between 2001 and 2022, cattle ranching drove the destruction of roughly 120 million acres of forest globally, an area larger than California. Most of that loss happened in the tropics, particularly the Amazon.

Palm oil and soy have also replaced millions of acres of tropical forest over the same period. In Indonesia, palm oil plantations remain a major force, contributing 14% of the country’s total deforestation in 2024. But pulpwood plantations, vast estates of fast-growing trees harvested for paper and packaging, actually overtook palm oil as Indonesia’s largest deforestation driver that year. The country lost 261,575 hectares of forest in 2024 alone, an area four times the size of Jakarta.

What makes agricultural clearing especially persistent is that it’s often legal. In Indonesia, 97% of deforestation recorded in 2024 occurred within legally permitted areas like existing concessions and infrastructure projects. A government moratorium on new permits to clear primary forest sounds protective, but it doesn’t apply to clearing within concessions that were already granted. Companies simply expand plantations on land they already have permission to use.

Logging and Road Building Open the Door

Logging accounts for 29.1% of tropical primary forest loss over the past two decades, making it the second-largest driver after agriculture. But logging’s impact goes beyond the trees that are cut. Roads built to access timber create pathways deeper into the forest, and those roads reliably bring further destruction. Research on Indigenous lands in the Brazilian Amazon found that for every additional kilometer of unofficial road, deforestation increases by 0.036 square kilometers in the surrounding area. Nearly 95% of all deforestation in the Amazon occurs within 5.5 kilometers of a road.

This pattern repeats across the tropics. Major roads open up previously inaccessible forest to settlers, ranchers, miners, and land speculators. The road itself may clear only a narrow strip, but the cascade of activity it enables can strip a region bare within years.

Mining Is Expanding Fast

Gold mining in the Amazon expanded by 400% between 1999 and 2012, growing from less than 10,000 hectares to more than 50,000 hectares. After the 2008 global economic recession drove gold prices up, the rate of mine expansion tripled, reaching over 6,000 hectares of forest cleared per year. In some parts of the Peruvian Amazon, deforestation from gold mining now exceeds all other forms of forest loss combined, including ranching, agriculture, and logging.

Small-scale and artisanal mining operations are a major part of the problem. By 2012, small mines made up 51% of total mining activity in the region, and their footprint had grown nearly 600% over 13 years. These operations are harder to regulate, often illegal, and leave behind not just cleared land but mercury-contaminated soil and waterways that prevent forest recovery.

Government Subsidies Fund the Destruction

A less visible but powerful force behind rainforest loss is money from governments themselves. Global subsidies for fossil fuels, agriculture, and fisheries exceed $7 trillion per year when both direct spending and indirect support are counted. That’s roughly 8% of global GDP. Direct government expenditures alone in these three sectors total about $1.25 trillion annually.

Agriculture subsidies specifically are responsible for the loss of 2.2 million hectares of forest per year, accounting for an estimated 14% of global deforestation. These subsidies often make it more profitable to clear forest for crops or cattle than to leave it standing, effectively paying farmers and corporations to destroy ecosystems. Reforming these payments is one of the most impactful levers available, but politically it remains difficult because the subsidies support powerful industries and large numbers of rural workers.

Wildfire Is Now a Major Factor

In 2024, wildfire became the single largest driver of tropical primary forest loss for the first time, responsible for almost half of that year’s total. Over the full 2002 to 2024 period, wildfire accounts for 16% of cumulative loss, but that number is climbing. Healthy rainforests are naturally resistant to fire because their dense canopy retains moisture. When forests are fragmented by logging and agriculture, the edges dry out and become vulnerable. Drought years, which are becoming more frequent with climate change, push the risk even higher.

This creates a destructive feedback loop. Deforestation and warming make fires more likely, fires destroy more forest, and the loss of that forest releases stored carbon and reduces rainfall, making the remaining forest drier and more fire-prone.

The Carbon Consequences

Tropical forests have historically acted as massive carbon sinks, pulling carbon dioxide from the atmosphere and locking it into wood and soil. That function is breaking down. Africa’s forests and woody savannas underwent a critical transition between 2010 and 2017, flipping from a net carbon sink to a net carbon source. Between 2007 and 2010, the continent’s forests were still gaining biomass. By 2010 to 2015, they were losing it, primarily because of deforestation in tropical moist broadleaf forests. This shift means forests that once helped slow climate change are now accelerating it.

The Amazon faces a similar risk. Modeling research published in 2025 projects that nine out of twelve Earth system models show Amazon dieback under high-emission scenarios. The tipping conditions: local temperatures rising above roughly 32°C and annual rainfall dropping below about 1,400 millimeters. Land-use change, meaning continued clearing, makes those thresholds easier to cross. If the Amazon passes its tipping point, the transition from forest to degraded savanna could involve an 80% or greater decline in the forest’s biological productivity.

Recent Progress and Its Limits

There is some positive news. Brazil reported that deforestation in the Amazon fell 11% between August 2024 and July 2025 compared to the previous year, with the cleared area dropping to 5,796 square kilometers. That decline reflects stronger enforcement and political will under Brazil’s current government. But 5,796 square kilometers is still a vast area, and the gains are fragile. Political leadership changes, commodity price spikes, or a severe drought year could reverse the trend quickly.

Indonesia’s situation illustrates how complicated “progress” can be. While illegal deforestation has dropped to just 3% of the total, legal deforestation surged in 2024 because existing concessions allow companies to keep clearing. Reducing deforestation in this context requires not just better enforcement but changes to the concession system itself.

The underlying economic equation remains the core problem. As long as cleared land is worth more than standing forest to the people and companies making decisions, rainforests will keep shrinking. Subsidies, commodity demand from wealthy nations, weak land tenure for Indigenous communities, and the lack of mechanisms to pay for the climate and ecological services forests provide all tilt the math toward destruction.
