EigoPro 準1級 読解 — Rewilding the Land

For more than a century, conservation in the West rested on a tidy assumption: that nature is best protected by fencing it off from human interference and freezing it in some pristine, prior state. Rewilding turns that logic on its head. Rather than maintaining a managed garden, its advocates argue, we should hand whole landscapes back to natural processes—letting rivers wander, forests advance, and large animals reshape the terrain as they see fit. The aim is not to preserve a snapshot of the past but to restore the dynamism that human activity has steadily suppressed. The most celebrated demonstration of this idea unfolded in Yellowstone. When wolves were reintroduced in 1995 after a seventy-year absence, they thinned and unsettled the elk herds that had been grazing the valleys unchecked. Willows and aspens, no longer browsed to stubble, recovered along the riverbanks; beavers returned to the regrown thickets; and the rivers themselves, stabilised by deeper roots, began to meander differently. A single predator, in other words, had rippled outward through the whole food web. To rewilders, the lesson is plain: remove the right species and an ecosystem can knit itself back together with remarkably little human help. Critics, however, caution against reading too much into one charismatic example. Reintroducing apex predators near farms and villages invites real conflict, and the rural communities who must live alongside returning wolves or lynx rarely share the enthusiasm of distant city-dwellers. There is also a deeper philosophical objection. If a landscape has been shaped by human hands for thousands of years—as much of Europe has—then "wild" is not a baseline waiting to be recovered but a romantic fiction. Letting nature take its course, the skeptics warn, may simply mean abandoning land to whatever happens to colonise it. What both camps share, perhaps, is a recognition that the old model of conservation-as-preservation is exhausted. The argument is no longer about whether landscapes will change, but about how much control we are willing to surrender, and to whom the wilder future ultimately belongs.

問 1

What is the main idea of the passage?

  • Rewilding proposes returning control of landscapes to natural processes, an approach that is promising but contested.
  • The reintroduction of wolves to Yellowstone has proved that predators harm ecosystems.
  • Scientists now agree that all human management of nature should be abandoned immediately.
  • Traditional conservation has succeeded everywhere except in the rural communities of Europe.
Phrase

we should hand whole landscapes back to natural processes

本文は「リワイルディング=自然の過程に主導権を返す試み。有望だが論争的」という論旨。

選択肢の解説Choice Analysis

「Rewilding proposes returning control of landscapes to natural processes, an approach that is promising but contested.」

正解

第1段でリワイルディングを『景観を自然の過程に返すこと (hand whole landscapes back to natural processes)』と定義し、第2段で Yellowstone の成功例を、第3段で批判 (Critics, however, caution...) を提示する。最終段は『古い保全モデルは exhausted』と締めくくる。よって『自然の過程に主導権を返す有望だが論争的な手法』が主旨。

  • 「The reintroduction of wolves to Yellowstone has proved that predators harm ecosystems.」

    = オオカミ再導入は捕食者が生態系に害を与えると証明した ━ 本文は逆で、オオカミが生態系を回復させた成功例として描いている。

  • 「Traditional conservation has succeeded everywhere except」

    = 従来の保全は欧州の農村以外では成功した ━ 本文は従来モデル全体を exhausted と評しており『農村以外は成功』とは言っていない。

  • 「Scientists now agree that all human management of nature should be abandoned immediately.」

    = 全ての人為管理を直ちに放棄すべきだと科学者は合意 ━ 本文は両陣営の対立を描いており『合意』も『直ちに全廃』も述べていない。

主旨設問は『定義 (第1段)→例 (第2段)→反論 (第3段)→結論 (最終段)』の構成を追う。両論併記型の本文では『有望だが論争的』のような中立的言い換えが正解になりやすい。

問 2

According to the passage, what happened after wolves returned to Yellowstone?

  • Beavers were deliberately reintroduced by rangers to rebuild the thickets.
  • Elk populations grew rapidly because their main competitors had been removed.
  • Pressure on elk eased, allowing riverbank vegetation, beavers, and river channels to recover.
  • The rivers dried up once the predators destabilised the food web.
Phrase

Willows and aspens, no longer browsed to stubble, recovered along the riverbanks; beavers returned

オオカミがエルクを間引き→川辺の植生回復→ビーバー復帰→川の流れも変化。

選択肢の解説Choice Analysis

「Pressure on elk eased, allowing riverbank vegetation, beavers, and river channels to recover.」

正解

第2段で wolves が elk herds を thinned and unsettled し、その結果 willows/aspens が回復し、beavers が戻り、rivers が meander differently になったと連鎖を描く。これを言い換えた『エルクへの圧力が緩み、川辺の植生・ビーバー・河道が回復した』が正解。

  • 「Elk populations grew rapidly」

    = エルク個体群が急増した ━ 本文ではオオカミが elk を thinned (間引いた) のであり、急増は正反対。

  • 「Beavers were deliberately reintroduced by rangers」

    = ビーバーはレンジャーが意図的に再導入した ━ ビーバーは植生回復に伴い自然に returned したのであり、人為的再導入ではない。

  • 「The rivers dried up」

    = 川が干上がった ━ 川は『異なる蛇行を始めた』のであり干上がってはいない。

問 3

What philosophical objection to rewilding does the passage describe?

  • City-dwellers are legally barred from advocating rural land policy.
  • Apex predators cannot survive in any landscape shaped by humans.
  • Rewilding is too expensive for most national governments to fund.
  • In long-inhabited regions, a truly "wild" baseline never existed, so there is nothing pristine to recover.
Phrase

"wild" is not a baseline waiting to be recovered but a romantic fiction

長く人が暮らした土地に『野生の基準点』など元々なく、回復すべき原初は存在しない。

選択肢の解説Choice Analysis

「In long-inhabited regions, a truly "wild" baseline never existed, so there is nothing pristine to recover.」

正解

第3段の後半で『a deeper philosophical objection』として、人の手で何千年も形作られた景観 (much of Europe) では wild は『回復を待つ基準点ではなくロマンチックな虚構 (a romantic fiction)』だと述べる。これを言い換えた『真に野生の基準点は元々存在しないので回復すべき原初もない』が正解。

  • 「too expensive for most national governments」

    = ほとんどの政府には高すぎる ━ 費用に関する記述はない。これは哲学的反論ではなく実務的反論の捏造。

  • 「Apex predators cannot survive in any landscape shaped by humans」

    = 頂点捕食者は人為的景観では生存できない ━ 本文は捕食者の生存能力を否定していない。論点は『基準点の不在』。

  • 「City-dwellers are now legally barred from advocating any rural land-use policy of any kind.」

    = 都市住民は政策提言を法的に禁じられている ━ 法的禁止の記述はない。都市住民と農村の温度差に触れただけ。

    これらの批判者には『野生』は実在の基準点でなくロマンチックな虚構だ。

  • Much of Europe has been shaped by human hands for millennia.

    欧州の大半は何千年も人の手で形作られてきた。

  • Letting nature take its course may just mean abandoning the land.

    自然に任せることは土地を放棄するだけかもしれない。
