Growing more plants is a vital step toward combating climate change because plants absorb carbon dioxide.  But as topsoil erodes, the Earth can support fewer and fewer plants. And the fewer plants we're able to grow, the more challenging it will be to control climate change and remove carbon dioxide from the atmosphere.  The relationship between climate change and erosion creates a tumultuous cycle. As climate change worsens, it also accelerates erosion. And as erosion continues to accelerate, so does climate change.
