Hide analysis

Forests are among the world's most valuable resources, both in a narrowly economic sense and in a broader, ecological sense. ███████ ████████ ████ █████ ██████████ ████████ ████ ██████████ ████ █ ███████ ██ ███ ███████ █████ ████████ ███████████ ███████ ███████ ███████████ ██████ █████████ ███ ███████ ████ ███████ ████ █████ ██████ ████ █████ ███

Context / Intro · Forests are important

Forests are both economically and ecologically important.

Main Point · Policy decisions about conservation of forests require understanding arguments for and against

Author will scrutinize two specific claims: 1. that forests create oxygen; and 2. that forests preserve biodiversity

Criticize Claim 1 · Forests are "the lungs of the earth"

This is a myth. Forests neither produce nor consume oxygen in net.

Claim 2 · Preservation of biodiversity requires stricter conservation of forests

Economic argument for preserving biodiversity: could lead to discovery of new medicines. Moral argument for preserving biodiversity: it's an intrinsic good.

Critique of Claim 2 · Is stricter conservation of forests really required?

First, deforestation isn't occurring as much as many believe. Second, deforested land that turn into wood plantations actually relieve economic pressure on forests.

The passage doesn’t make any comment on what diseases the medicines developed from rain-forest plants will be able to fight, so we cannot say that many scientists believe the claim in (B).

This is supported in P3. Many scientists believe that some tropical plants may help with medical research, which indicates a value of rain-forest plants.
