In Tierra del Fuego, at the southern tip of South America, there's only one garbage processing plant, no recycling facilities, and voracious winds that regularly exceed 62mph. This means that plastic waste, much of which is carried there by ocean currents from other countries and deposited on the shore, ends up being blown all over the picturesque island. Marilita Quintana Molina, from the indigenous Selk'nam community, collects this waste and uses it in her art to shed light on the magnitude of this issue.

“To clean up nature is to clean up our home,” she says. As part of the Young Climate Prize, Marilita was mentored by Abraham Cruzvillegas, a celebrated visual artist from Mexico. Since 2007, he has produced a body of work he calls “autoconstrucción”. Taking inspiration from his hometown, a village built through collaborative construction with recycled and found materials, Cruzvillegas's sculptural installations are often playfully composed from inexpensive materials.
