Opinion: The internet was once a tool for justice. It can be again

About four decades ago, as day broke on the morning following Chico Mendes’ assassination, demands for justice were already on the desks of government officials around Brazil. The environmental movement’s response reached them before the news, and our demands were simple: Do something. Defend environmental defenders. Refuse to accept these deaths as inevitable.

Now, with the climate crisis escalating and its impacts becoming increasingly severe, underscored by the Inter-American Court of Human Rights’ landmark advisory opinion highlighting states’ legal obligations to protect current and future generations from climate change, the urgency of these demands and the critical role of digital tools in amplifying them have never been clearer.

Chico Mendes was not the first environmental defender murdered for his work. Nor was he the last. But the news of his killing was likely the first to be turned into an international story — and rallying cry — in real time. It reflected the beginning of a new era for the environmental movement, and the world beyond.
