Check your Knowledge:Create your own definition of sustainability.
• People – services promote fairness, tolerance, and community participation/leadership
• Planet - services are well designed and built, include the natural environment, and are considerate of nature.
• Profit – services take into account full-cost analysis of activity and promote the local economy
• Fair for everyone - including people, planet, and profits, now and in the future
Extension:Add examples of how your daily activities are sustainable.
Sustainability
Sustainability is making sure the needs of the current population are met without compromising the needs of future
generations.

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.
Activity: Idea Sorting1. Create a 3-Column t-chart on the chart paper
provided. Label as listed below:
2. Cut out and sort each piece of EVIDENCE in the correct category.
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.

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.

Biosphere = Where these three spheres interact (Atmosphere, Hydrosphere, Lithosphere) life is created.
The biosphere starts at the bottom of the ocean floor and reaches to the upper limits of the lower atmosphere where there is life.
Sustainable development is very important when it comes to these 4 spheres.

formed by the interaction of all living things in an environment with one another as well as with the non-living elements climate, water, and soil) that support life.

• 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’.
– Write a letter to Stephen Harper arguing for Canada’s adoption of managing forests based on its ‘natural capital’ not just its market value.
