    ‘Tree farts’ make up about a fifth of greenhouse gases from ghost forests

    Heat-trapping gases from dead trees play an important role in the environmental impact of “ghost” forests.

  5. Scientists Say: Respiration

    Breathe in and out, that’s respiration. Have a cell break down sugars for energy, and that’s respiration too.
