Phytoremediation: Using Plants to Clean Contaminated Soil
Quick fact
Some plants, like alpine pennycress, can accumulate zinc in their tissues at levels up to 30,000 times higher than normal, making them natural vacuum cleaners for polluted soil.
Why this is interesting
What if the solution to cleaning toxic soil lies not in heavy machinery or harsh chemicals, but in the silent work of sunflowers, ferns, and grasses?
