Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Give three ways a rainforest is directly valuable to the people who live in or near it.

    Model answer

    It supplies food, timber, fuel and traditional medicines, it provides homes and livelihoods for indigenous groups, and it can earn income from visitors.

  2. 2

    Why are tropical rainforests important for the world's climate?

    Model answer

    They take in and store enormous quantities of carbon, so keeping them standing slows the build-up of greenhouse gases and the warming it causes.

  3. 3

    How do rainforests regulate the movement of water?

    Model answer

    The canopy intercepts rain and the trees return moisture to the air, which keeps regional rainfall reliable and slows the run-off that would otherwise flood rivers.

  4. 4

    Why does the rainforest have value for people who will never go anywhere near one?

    Model answer

    Its carbon store, its influence on rainfall and the species and possible future medicines it holds benefit everyone, wherever in the world they live.

  5. 5

    What does it mean to manage a rainforest sustainably?

    Model answer

    To use it in a way that meets people's needs now without damaging it, so that it is still there and still working for future generations.

  6. 6

    What is selective logging?

    Model answer

    Felling only chosen trees, such as older or less valuable ones, and leaving the rest standing so the canopy survives and the gaps grow back naturally.
