Nearly 80 million people each year are added to the world’s population
About 80% of the goods and services produced from the world’s resources are consumed by 20% of the worlds population
Massive amounts of land and water are required to feed all these people
A Needy World

Around the World, approx. 1.6 Billion people depend on forests for food, shelter, and employment
Forests protects biodiversity and removes Carbon Dioxide from the atmosphere
Hectares upon hectares of forest around the world is being cut down
Deforestation

12% of British Columbia’s forests are protected
In BC, forests are used for recreation, industry, research and as a means of revenue
Historically, it has been argued whether or not forests should be used for economic or heritage purposes
Ex. Great Bear Rainforest

The globalization of agriculture has led to unsustainable practices such as offshore farms and large-scale farming operations
Approaches keep costs down by using large scale, assembly line methods to produce products
GMOs

Herbicides and Pesticides are sprayed on crops
Such chemicals are dangerous to the environment; seep into ground water or streams
Plants are genetically modified to produce large yields of food

2.5% of the world’s water is fresh water
70% of that is in the form of ice caps and glaciers
Only 0.3% of the world’s fresh water is in lakes and rivers
Canada’s contains 20% of the world’s water resources

The majority of settlements and cities around Canada are located near a water source
Surface water can be polluted from municipal, agricultural and industrial sources
Industries such as oil refineries, pulp mills, and chemical factories release wastes into rivers and oceans
90% of the municipal waste is found in either the Fraser River or surrounding waters of Vancouver
