Niba: Scientists say that if we plant more sunflowers, it could help slow down global warming. It has to do with how much light they reflect. It's the same idea as, like, whitewashing your house to make it more energy-efficient in hot climates. Light colors reflect the heat and dark colors absorb it. So, planting reflective crops can have a similar effect.

Sunflowers are great at this, because replacing soy or corn with sunflower fields turns that land that used to be a dark brown or green into a light, reflective yellow. And simulation suggest that brighter-colored crops like sunflowers could reflect more light and decrease how hot the air gets.

That's all because plants that grow in hotter climates have adapted excellent sunlight reflecting skills to help them beat the heat. This mainly works in places that are above 30-degrees latitude - so, much of the US, Canada, Eurasia, and Southern South America.

Brighter crops could help keep temperatures down.
