Managing Renewable Resources Successfully
exploiting a renewable resource in an unsustainable way
what is mining the resource
what two resources are needed for farming
what are suitable climate and deep, fertile soils
what is the importance of money for the industry
fishing is an important industry in Atlantic Canada and parts of British Columbia, without these jobs, small towns would dissappear
what are the resources needed for forestry and what are some problems
resources: climate and soils that are appropriate for the type of tree being grow, existing forests provide seeds for new generations of trees
problems: deforestation/bad forestry practices can result in scrub bush, soil erosion
name three ways farming impacts the environment
what is greenhouse gas emissions, methane, and clearing forests to make room for farmland
using a resource sustainably so that it can be used still in the future without it depleting in stock or quality
what is sustainable yield management
temperature is measured in what
what is the importance of history for the industry
fishing is Canada’s oldest industry dating back to 1497
what is an old growth forest
one that has never been logged
what are three effects of climate change on forestry
what are wild fires, decrease in size of forests, and increased forest damage from insects
the three main industries
what are fishing, farming, and forestry
true or false: an area could have lots of precipitation but due to heat there could be a big demand from all living organisms
true - aridity index is helpful to measure this
what is the importance of sustainability for the industry
the disaster of the Atlantic Cod Fishery has taught us a valuable lesson about unsustainable fishing practices and resource management
where are most of Canada’s pulp and paper mills found
mostly found in the Boreal, West Coast, and Cordilleran forests
further north - trees are too small
further south - not enough trees to support major mills
what is the forest stewardship council (FSC)
this industry is at moderate risk
what is farming
what are two farming issues aside from impact on the climate
soil deterioration due to bad farming practices (ex. monoculture), and urban sprawl and growth taking over land suitable for farming
name a category of fish, its description and some examples
what is a shellfish
description: animals without a backbone but with hard, protective shells
examples: lobster, crab, oyster, shrimp, mussels, etc.
what are the two primary perspectives on forestry
1) should be preserved in a natural state
2) they are needed to provide a source of wealth and jobs for Canadians
what organization sets the standards for sustainable fishing practices
what is the marine stewardship council (MSC)
these two industries are at a moderate to high risk
what is fishing and forestry
explain intensive farming vs. extensive farming
intensive: relatively small areas of land, requires large amounts of labour, food can perish quickly (ex. greenhouse)
extensive: large areas of land, uses more machines, food does not easily perish (ex. poultry farms)
describe inshore vs. offshore fisheries
inshore: within 16-25km of the shore, run mainly in warmer months, small crew size, 10% of total catch
offshore: edges of the continental shel, run year round, very large crew size, 90% of total catch
name and describe the three types of logging in Canada
1) clear cutting: fastest and cheapest method, remove every tree
2) shelterwood logging: only a part of the forest, seed bearing trees are left behind to regenerate the forest
3) selective cutting: harvest only mature trees of desired shape, size, etc., less disruptive to the forest environment
explain the 5 factors of the unsustainable cod management and the 5 things that can be done to prevent it
5 Factors of unsustainable cod management:overfishing, improved fishing technology, uncontrolled foreign fishing, destructive fishing practices, changes in natural conditions
5 Things to prevent it:catch limits, selective fishing gear, seasonal restrictions, marine protected areas monitoring and enforcement
