Living Green - Episode 65 - Trees A Source Of Fuel

The video discusses the potential of using fast-growing Poplar trees as a renewable energy source to reduce carbon emissions. Scientists in southern England are studying these trees to understand their rapid growth compared to other trees. Researchers across Europe are identifying genetic factors that influence the growth and characteristics of Poplar trees. The goal is to select the best trees for environmental sustainability, focusing on those that grow quickly, absorb carbon efficiently, and resist disease.
