A group of kids have blocked a massive real estate development project in Cancún, one of Mexico’s premier resort destinations. The plan called for the leveling of dozens of acres of mangrove forest and destroying the habitat of countless crocodiles and other animals. In a strange series of events, a group of 113 children of local environmental activists filed a complaint against the real estate developer in September that the development was infringing on their constitutional right to a healthy environment. The strategy was inspired by a similar case earlier this year in the United States, when a group of children filed a case using a similar claim to demand action from the Obama administration to combat climate change. The judge ruled last week in favor of the children, approving a request to permanently suspend the 170-acre mixed-use project which is reportedly worth $900 million. The project is backed by Mexico’s tourism development agency, and local environmentalists have been fighting it since the project began more than two decades ago. However, the Judge also ordered the children to pay a bond of 21 million pesos (about $1.2 million) to offset developers’ losses. Attorneys for the child environmentalists argue that the bond should not apply to minors.
