Researchers found that intercropping, an ancient Maya farming technique, is effective in nutrient-poor Martian soil.
The study suggests that intercropping can improve crop yields and combat the impacts of climate change on Earth.
There are challenges in adapting space agriculture techniques to regions most in need due to existing power inequalities.

Why this matters: As climate change degrades arable land, finding sustainable agricultural practices is crucial for global food security. Techniques developed for extraterrestrial farming could help restore Earth's depleted soils and ensure a reliable food supply.
Break Free From Plastic says multinational corporations are pumping out so many single-use plastics that harmful plastic production could double by 2030 and possibly triple by 2050.
Indigenous people, environmentalists and industries vie for control over lands that can offer economic benefits or climate protection — but not always both.
