Thin on the right so far
Only 2 of the 9 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Police in Brazil targeted a group suspected of using chemicals to clear 10,180 hectares of Amazon rainforest in the northern state of Para. The operation, carried out on 29 July 2026, involved 13 search warrants and three precautionary measures, as stated by officials. No arrests were made during the raids.
The cleared land was converted into pasture for commercial use, investigators said. The suspects are alleged to have sprayed chemicals to degrade vegetation in the city of Uruara before cutting down trees. The timeline of the chemical application and deforestation remains unclear.
Those under investigation could face charges including environmental crimes, illegal use of toxic substances, fraud in environmental proceedings, and criminal conspiracy. The Amazon rainforest, which plays a critical role in global climate regulation, has seen reduced deforestation in 2025, with a 23.5% decline compared to the previous year, according to MapBiomas.
Nearly 290,000 hectares of forest were cleared in 2025, with agriculture and cattle ranching responsible for 99% of the loss. The operation highlights ongoing concerns about illegal deforestation despite government efforts to curb it.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
5 rated outlets
- The left-rated reports agree that Brazilian police carried out 13 search warrants in Para state on 29 July 2026, targeting a group accused of using chemicals to clear 10,180 hectares of Amazon rainforest. The land was later converted to pasture for cattle ranching. No arrests were made.
- The Associated Press report led on the scale of the deforestation and the suspects’ alleged methods, including the purchase of chemicals and concealment of environmental data. It quoted investigators stating the cleared land was for commercial use and noted potential charges of environmental crimes, fraud and conspiracy.
- All five left-rated digests included the size of the deforested area and the lack of arrests. None of the digests mentioned the timing of the chemical spraying or the broader climate impact of Amazon deforestation, details carried only in the Associated Press report.
