Colombia and Brazil Lead the Deadliest List for Environmental Activists

Rising Threats to Environmental Defenders

In 2025, environmental defenders in Colombia and Brazil faced the highest risk of death, accounting for 52 % of all killings in the region. The findings, released by a regional watchdog, highlight the escalating violence against those who oppose extractive projects. The report examined incidents across Latin America, noting that the two countries have become focal points for lethal attacks. It cites 2024 statistics, where anti‑mining activists were targeted in Honduras and other nations, but the bulk of fatalities occurred in Colombia and Brazil.

Data show a sharp increase in attacks on activists since 2019. In Colombia, armed groups linked to illegal mining and logging have intensified their campaigns. Brazil’s vast Amazon region has seen a surge in confrontations between indigenous communities and loggers. The report details that 52 % of the region’s 2025 killings were concentrated in these two countries, underscoring a regional trend toward extreme violence.

Why Are Activists Targeted?

The core motive is economic gain. Extractive industries often face opposition from local communities. When activists block access to resources, they are perceived as obstacles to profit. In both Colombia and Brazil, powerful interests have historically used intimidation, threats, and violence to silence dissent. Legal protections for environmental defenders remain weak. Courts in these nations frequently fail to prosecute perpetrators, creating a climate of impunity. The report stresses that the lack of accountability fuels further aggression, as attackers believe they will face no consequences.

The consequences extend beyond individual lives. Communities lose leaders who advocate for sustainable practices. Local economies suffer when traditional knowledge holders are silenced. International investors react to the instability, sometimes withdrawing funding or shifting to less contentious projects.

What is the main reason for the high death toll in Colombia and Brazil? The primary driver is the clash between extractive industries and local environmental defenders. Economic interests often override human rights, leading to violent suppression.
