One of the following regions has the world's largest tropical peatland, which holds about three years worth of global carbon emissions from fossil fuels; and the possible destruction of which can exert detrimental effect on the global climate.Which one of the following denot that region ?

A Amazon Basin
B Congo Basin
C Kikon Basin
D Rio de la Plata Basin

Correct answer: (b) Congo Basin

Explanation

  1. A

    Amazon Basin

    Amazon Basin. Huge forest carbon; the “three years of fossil emissions” peat claim is the Congo Cuvette.

  2. B

    Congo Basin

    Congo Basin. World’s largest tropical peatland complex.

  3. C

    Kikon Basin

    Kikon Basin. Not a standard name for this peat store.

  4. D

    Rio de la Plata Basin

    Rio de la Plata. Estuary of Paraná–Uruguay; not that peatland.

Summary. Official key is (b) Congo Basin. The central Congo peatlands (Cuvette Centrale) are the world’s largest tropical peatland and store on the order of three years of global fossil-fuel carbon emissions. Draining or burning them would matter for climate. Amazon carbon is mostly in trees, not this peat statistic.
