Living Green - Episode 65 - Trees A Source Of Fuel

The video discusses the potential of using fast-growing Poplar trees as an alternative to fossil fuels for electricity generation, which could help reduce carbon dioxide emissions. Scientists in southern England and across Europe are studying the genetic factors that contribute to the rapid growth and other beneficial characteristics of Poplar trees. By selecting the best trees, which are fast-growing, carbon-absorbing, and disease-resistant, growers can promote environmental sustainability.

What is the primary focus of scientists studying Poplar trees in southern England?

• To analyze their water consumption

• To study their impact on local wildlife

• To find out how they can grow faster than other trees

• To understand why they grow slower than other trees

How could fast-growing Poplar trees help in reducing carbon emissions?

• By absorbing more sunlight

• By being used as a food source

• By replacing fossil fuels for electricity generation

• By producing more oxygen

What are researchers across Europe trying to identify in Poplar trees?

• Genetic factors controlling their growth and characteristics

• The ideal climate for their cultivation

• The best soil for their growth

• The most effective fertilizers for them

Which characteristics are researchers looking for in the best Poplar trees?

• Slow growth, low water usage, and high fruit yield

• Fast growth, high carbon absorption, and disease resistance

• High wood density, slow growth, and drought resistance

• Low carbon absorption, fast growth, and high water usage

What is the ultimate goal of selecting the best Poplar trees?

• To improve their fruit yield

• To enhance their aesthetic appeal

• To promote environmental sustainability

• To increase timber production
