Will roots save the world? | DW Documentary
Humanity faces major challenges. Could roots hold the answers? It’s possible: Research shows that roots have the potential to provide food for the world's population, stop climate change and help extract resources in an environmentally friendly way.
Plants must withstand periods of drought and heat, as well as flooding, and they use their roots to do this. Roots also help them actively search for nutrients in the soil, while warding off dangers such as pathogens and toxins. Now, scientists at the research institute Forschungszentrum Jülich are investigating root growth using high-tech methods. The goal is to breed stress-resistant seeds for plants with robust roots. They are not alone: In Sweden, Professor Linda Maria Mårtensson is conducting research on a perennial wheat variety that will ensure higher yields while protecting the soil.
Along the world's coasts, too, roots are a lifesaver. Coastal ecologist Professor Tjeerd Bouma has discovered that if special grasses are planted in front of dikes, they create a salt marsh that acts as a natural breakwater.
Meanwhile, geochemist Dr. Oliver Wiche of the Technical University of Freiberg is researching something known as "phytomining." He wants to know which plants are best suited for mining metals from the soil. Could this root research give rise to a new, environmentally friendly branch of industry?
