  1. Why does a warming climate shift where a species can live?

    • Its tolerance band moves poleward and uphill
    • Animals prefer new postcodes
    • Maps are redrawn for fun

  2. What measurable changes follow clearing forest for farms?

    • More birds and clearer rivers
    • Fewer birds and browner rivers
    • No change anywhere

  3. Small isolated groups are usually the first to die out as habitats shrink.

    Circle one:   True   False

  4. A town plans a reserve on farmland. What is the honest cost statement?

    • No cost to anyone at all
    • Habitat saved, but farmers lose land and wardens need pay
    • Only shoppers ever pay

  5. A valley warms and a bird species appears higher up each decade. What best explains it?

    • The birds forgot the valley path
    • Binoculars improved downhill
    • The birds track their comfort band uphill

  6. Why might equal pollution cuts for all countries be unfair?

    • Rich countries never polluted at all
    • Equal cuts may keep poor countries poor
    • Cuts always cost nothing

  7. A factory plan brings jobs but ships goods far with weak rules abroad. What is the strong answer form?

    • Name who gains, who pays, and whether the trade is worth it
    • Jobs only, ignore the rest
    • Ban all trade everywhere

  8. Warming simply kills species where they stand, without moving any ranges.

    Circle one:   True   False

People, land, waste and warmer maps W1-mt_BiYCyohfyI-s1

  1. Its tolerance band moves poleward and uphill · Species track the temperature and rainfall they cope with best.
  2. Fewer birds and browner rivers · Lost shelter means fewer birds, and bare soil washes into rivers.
  3. True · Fewer habitats mean fewer ways of life, and small groups blink out first.
  4. Habitat saved, but farmers lose land and wardens need pay · Every plan is argued over because saving species costs someone something.
  5. The birds track their comfort band uphill · Range maps redrawn decade by decade show the uphill slide.
  6. Equal cuts may keep poor countries poor · Rich growth rode on past pollution, while poor builders still need room to grow.
  7. Name who gains, who pays, and whether the trade is worth it · Trade-offs need both sides priced before any verdict.
  8. False · It moves needed conditions, so ranges shift rather than just ending on the spot.
