The world's rainforests are under unprecedented pressure, with a myriad of new demands for resources pushing these vital ecosystems to the brink. A recent report highlights the alarming state of affairs, revealing how the extraction of critical minerals, biofuels, and pulp is exacerbating existing threats from cattle ranching, monocrops, oil, and logging. The Amazon, Congo basin, and southeast Asia are all feeling the strain, with mining, in particular, having a far greater environmental impact than previously thought.
One of the most concerning aspects is the secondary impact of mining, which includes water pollution and the construction of roads, settlements, and infrastructure. This has led to 10-30% of the world's forests being affected, and the report predicts this proportion will only increase. The authors emphasize the urgent need to reduce and replace the use of products from forest regions, rather than simply adding new forms of consumption.
The report tracks commodity trends threatening these rainforests, noting how they are weakening their ability to regulate temperature, store carbon, recycle water, and provide a home for nature. Cattle ranching, agriculture, and gold mining are the biggest threats, with all three expected to expand. The Brazilian government's 10.2% increase in beef production is forecast to cause at least 57,000 sq km of deforestation by 2034, and global meat production is expected to increase by 13% over the same period.
Gold mining is also a significant issue, with open-pit mines already covering 1.9m hectares of the Amazon biome. The demand for jewelry, technology, and ingots is projected to cause an additional 375 sq km of deforestation by 2028. Oil, gas, and coal are also playing a growing role in rainforest destruction, with the Amazon being one of the fastest-growing fossil fuel frontiers.
The biofuel sector, which claims to be a sustainable alternative to oil and gas, is another source of pressure. The report estimates that 52m hectares of additional cropland will be needed to meet the projected 2030 global demand for biofuel, leading to the clearance of between 31,600 sq km and 35,000 sq km of Amazon vegetation by 2035. Oil palm pressures are also growing, with the Congo basin potentially becoming a new frontier for this industry.
The report also highlights the impact of throwaway products marketed as 'green', such as the fast-fashion popularity of viscose and the paper bags often touted as a 'green' alternative to plastic carriers. These products are not always sustainably sourced, adding to the pressure on Indonesia's forests.
The authors propose possible solutions, including improved transparency in supply chains and stronger enforcement of regulations. Recycling could also help reduce the need for new mine development. However, the lead author, Barbara Kuepper, emphasizes that a reduction in resource use is essential, as recycling alone will not be enough to address the overall use of resources.
In conclusion, the world's rainforests are facing an unprecedented crisis, with a multitude of new demands for resources pushing these ecosystems to the breaking point. It is imperative that governments and industries take action to reduce and replace the use of products from forest regions, and that consumers in developed countries demand more sustainable alternatives.
