What was one of the scariest stories of 2019? The massive wildfires that were visible from space as they raged across the vast Amazon rainforest, spreading from Brazil into Bolivia, Paraguay, and Peru. The crisis followed the election of Brazilian president Jair Bolsonaro, a right-wing ideologue who swiftly weakened environmental protections and encouraged deforestation of the Amazon.

Beyond being the world’s largest carbon sink, the region is home to one in 10 species on Earth. When tropical rainforests burn down, or are destroyed to develop industrial plantations for palm oil—which is added to chocolate and baked goods, turned into fry oil, and added to all manner of snacks, cosmetics, and soaps—these tropical creatures are pushed from their habitats and driven closer to the brink of extinction. The equivalent of 300 football fields of rainforest is destroyed every hour to make way for palm oil plantations, according to the World Wide Fund for Nature—and in the African and Southeast Asian rainforests, this has decimated the populations of vulnerable creatures including tigers, elephants, and rhinos. Orangutans and other primates are particularly besieged, as studies suggest that most areas suitable for growing palm oil overlap with their habitats. Palm oil production impacts humans, too—Indigenous people have been forced from their lands, and plantation workers sickened by pesticides and contaminated water.

According to the Rainforest Action Network (RAN), palm oil appears in roughly half of packaged grocery store foods. (US Food manufacturers increased their use of the world’s cheapest vegetable oil after the FDA started enforcing limits on trans fats in 2005.) The good news is that consumer purchasing power can play a major role in rainforest health.

One step you can take to curb deforestation is to get wise to the details on product packaging. Fewer ingredients mean you’ll have less of a chance of a palm oil encounter, which has dozens of ingredient list aliases—vegetable oil, palmate, cocoa butter equivalent, glyceryl stearate, sodium lauryl sulfate, and glyceryl stearate, to name a few. Of course, you can always demand that your favorite food companies clean up their acts by either finding alternatives to the stuff, or sourcing their palm oil responsibly. (Check out RAN’s handy scorecard, which keeps track of product manufacturers that have pledged to limit deforestation,—and contributions to the climate and humanitarian crises—by switching to more sustainable forms of palm and other oils.)

Thanks to consumer action and grassroots activism, the candy industry has made some strides in recent years, with major corporations including Nestle and Hershey removing palm oil from many beloved Halloween staples. How can you help keep Big Candy accountable? Here’s a handy list of classic candies that are nostalgic and easy to pass out but that do not contain palm oil, compiled with help from Products Without Palm Oil( which provides fantastic free resources for consumers). Remember to stay vigilant for labels’ hocus pocus, as ingredients can vary within a single brand’s offerings (looking at you, M&M’s and Reese’s), and don’t be tricked by those discount bags of mixed candy: Stick to one type (or make your own mix), and it’s easier to shirk the dreaded industrial palm oil.
