SUSTAINABLE DEVELOPMENT• Sustainable Development refers to people taking resources from nature

with minimal disturbance to the environment. • Sustainable development provides people with resources needed today

without threatening resources need for the future.

Clear-Cutting

• Most common method for harvesting trees (93% of Canada’s forest area harvested is clear-cut).

• +’s – resembles natural disturbances like fire, wind, floods, and insects, allowing natural regeneration.

• -’s – leads to biodiversity loss.

Sustainable development thus means:

1. Resources can be used over and over.

2. Not just resources are preserved but so are people’s jobs.

Thus employment also has to do with sustainability.

Activity: Venn Diagram1. Read the pink EVIDENCE STATEMENTS (showing the

impacts of deforestation) and organize in the correct category of the venn diagram.

2. Identify which EVIDENCE is FOR (+) and AGAINST (-) deforestation.

3. Decide whether current deforestation practices are sustainable. Explain why or why not using the EVIDENCE STATEMENTS to support your answer.

– If sustainable: What EVIDENCE shows benefits to people, profit, and planet.

– If unsustainable: What EVIDENCE must be addressed to improve sustainability and reduce negative impacts to people, profit, and/or planet.

Homework

• Read the article, Will saving a B.C. forest save us money?

• Highlight all examples that demonstrate the value of forests (e.g. animal habitat).– Decide whether the points you highlighted

represent the forest’s market value or non-market value—it’s ‘natural capital’.

– Complete the chart at the end of the article.
