[00:00:00]This flower is looking for food.

[00:00:02]But underground, something else can use the same door.

[00:00:06]It is a sunflower.

[00:00:08]We grow it for color, for height, for light.

[00:00:13]But the real work is not happening above.

[00:00:16]Its roots reach into the soil and pull in water.

[00:00:19]With that water, come nutrients.

[00:00:22]Potassium for growth, calcium for strength.

[00:00:26]But in damaged ground, other elements can hide in that water.

[00:00:31]Cesium. It behaves like potassium.

[00:00:35]Strontium. It behaves like calcium.

[00:00:39]To the root, the difference is not always clear.

[00:00:42]So when the root opens its door for potassium, cesium can walk through.

[00:00:47]The root is not choosing danger. It is following chemistry.

[00:00:52]And part of what was hiding in the ground begins to move upward.

[00:00:56]Into the stem, the leaves, the body of the flower.

[00:01:02]In 1994, someone tested [music] this.

[00:01:05]Researchers placed sunflowers on floating rafts, 1 km from the Chernobyl reactor.

[00:01:12]The roots hung below the surface into contaminated water.

[00:01:17]They began pulling cesium 137 and strontium 90 from the pond.

[00:01:23]In one reported test, about 95% of the radioactivity was gone in 10 days.

[00:01:30]But the flowers did not destroy what they absorbed. Everything stayed inside.

[00:01:35]Before they could bloom, they were harvested, burned, the ash sealed in glass and buried.

[00:01:43]The problem did not vanish. It moved.

[00:01:47]From the water into the flower.

[00:01:51]The flower is not erasing the problem.

[00:01:53]It is carrying part of it.

[00:01:56]That is what this plant can do.

[00:01:58]Not everywhere.

[00:02:00]Not every time.

[00:02:02]But when the ground needs help, the roots are already reaching.

[00:02:07]Above the soil, it still looks like a sunflower.

[00:02:10]A flower we grow for beauty.

[00:02:13]Also part of repair.

[00:02:16]Nature speaks.

[00:02:17]We translate.
