In the schools of the state of Mexico, neighboring Mexico City, there is a charter circulating in which the students commit themselves to 24 actions aimed at halting global climate change. Those who sign it pledge to avoid using plastic bags, to sort the recyclable materials from their garbage, to use low-energy light bulbs, to turn off appliances when not in use, to reduce paper use, and to purchase products in returnable containers, among other practices. The charter “creates a chain, and its goal is simple but powerful: to take on commitments with the environment,” Moisés Bolaños, 16, a high school student in Mexico state, told Tierramérica.

The missive to join the fight against global warming has been circulating since late June and has already reached many different neighborhoods. It is being promoted by the non-governmental group Ambientalmex and the state of Mexico's Secretariat of Environment.
