In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Without her own home and pressured by rent, a 25-year-old bought a small 15-meter boat, gradually renovated the interior by herself, transformed the interior with paint, new flooring, a larger bathroom, and started living on the canals, paying much less per month.

Heir bought 23,000 degraded acres in the Scottish Highlands, fenced the area, planted nearly 1 million native trees, and transformed empty mountains into a forest officially recognized after meeting 15 evaluation criteria over 20 years.
