An estimate of how much land and water is needed to support a person’s lifestyle Includes the land and water needed to produce the resources as well as wastes produced. The average Canadian requires 8.9ha (17 football fields) to maintain their lifestyle. If everyone on earth lived like this we would need 5.7 earths.
3
Calculating ecological footprints enables us see how much we need to change or evaluate progress. Can be calculated for a person, building, town, province, country, or continent.

Environmental steward - taking care of our natural resources to ensure that they are used in sustainable ways for current and future generations. Stewardship includes activities such as: Reducing the amount of resources we use Reusing items instead of throwing them away Renew /recycling used items. Conserving existing ecosystems and restoring damaged ones.
6
In the 1980’s the Environmental Farm Plan (EFP) was created. The EFP is a tool that farmers can use to identify environmental problems on their farms and develop action plans to address these problems Example: pesticides have been reduced by 50 percent on Ontario farms since the EFP started.
7
Integrated pest management - method of pest control that uses knowledge about a pest’s biology and habitats. Uses common sense methods to control pests, not eliminate them. Rotating crops can help because many pests only eat one kind of plant.
8
Soil is a limited resource. It takes hundreds of years to form Soil conservation - using farming methods that protect the soil from erosion and loss of nutrients. Example: No-till farming leaves roots from previous year’s crops. The roots help to prevent erosion. Not all plants can be planted this way.
9
Organic farming - organic farms do not use chemical fertilizers or pesticides. Reduces water pollution. However Cannot produce the same amount of food as a non- organic farm.
10
Centralized production of food is more efficient because one plant ships everything. This is possible due to modern refrigeration and efficient transportation networks. But if contamination occurs all the food must be recalled, and this is very expensive. Currently, in North America, many foods are grown and processed on a very large scale. It is very efficient, but.....
11
Decentralized food production can help reduce this problem And locally grown food takes less energy to bring to a store. Sustainable agriculture and eating locally produced foods are connected. Buying locally supports local farmers – farmers continue to farm Locally grown produce tends to be fresher
12
Forest Stewardship Council of Canada (FSC) is a non-governmental organization. This organization sets standards for sustainable forest management and certifies forests and forestry practices that meet their standards.
13
For a forestry practice to be certified: Waterways and wildlife habitat have to be protected. Parts of the forest have to be preserved. The cut areas have to be replanted. The cut areas cannot be replanted with just a single species. The forest must be able to achieve a wild state.
14
Customers can tell if a there wood products have been cut in a sustainable manner by looking for the FSC symbol.
15
Like a wild forest, an urban forest includes all the trees and shrubs present as well as their soils.
16
Healthy urban forests can help communities achieve many sustainability goals, such as removing excess carbon from the atmosphere. Large trees can remove 50 times more carbon than small trees can. They also reduce energy consumption by providing shade. Shaded buildings = less air conditioning = energy conservation
17
Slow run off from rainstorms Reduces water in storm-sewers Reduced soil erosion Filter chemicals in the air Repair damaged soil Habitat for other species Nice to look at
18
The thousands of large buildings and millions of homes in Canada have a significant effect on the environment. Building them, living in them, and heating and cooling them uses energy, uses many different resources, and produces many different types of pollution.
19
The Canada Green Building Council uses the Leadership in Energy and Environmental Design (LEED) rating system. Libraries, schools, office buildings, and homes can be scored on Water consumption Energy consumption Use of renewable resources Reuse and restoration of buildings Incorporating daylight
20
Manufacturers of cleaning products are introducing “green” cleaning products that do not have phosphates and other substances that cause eutrophication or degrade ecosystems in other ways.
21
Many manufacturers have their products certified by independent ecological certifying organizations, such as EcoLogo.
22
Bullfrog Power is an Ontario company that sells environmentally friendly electricity produced from renewable sources such as wind turbines and low-impact hydroelectric projects.
23
Boomerang paints takes recycling seriously. It takes leftover paint from recycling centres, sorts the leftovers by colour, and blends similar shades into new paint shades. The leftover paint cans are melted down and reshaped into new paint cans. The reclaimed paint is then sold in the recycled cans.
