Victims or Saviours – Can Plants Protect Us Against Global Warming? - Audio

✓

Claim

Plants produce the oxygen we breathe and the food we eat. By assimilating carbon dioxide, they dampen the current rise in carbon dioxide concentration and thereby global warming. To predict future changes, it is important to investigate how plants are affected by elevated carbon dioxide concentrations and by increased temperatures. Can enhanced plant growth counteract global warming or will global warming lead to the extinction of plant species? Can we offset our carbon emissions by planting trees or is it better to invest in new technologies for the production of biofuels? These and similar questions will be addressed in the lecture.
