GREENSHOUSE EFFECT
ECOLOGICAL FOOTPRINT - An ecological footprint is a measure of how far we consume resources and the land needed to deal with the waste created. Australia has one of the largest ecological footprints in the world. Australia's average is about 6, the world's average is 2.8, the sustainable average is 1.7.
WHAT IS THE GREENHOUSE EFFECT? - Approximately 50% of the Sun's energy is absorbed, and the other 50% reflected back. Greenhouse gases trap some of the escaping light energy which becomes heat.
WHAT ARE THE GREENHOUSE GASES? - Carbon dioxide, nitrous oxide, methane and fluorinated gas.
EACH OF THEIR GAS PERCENTAGES (%) - carbon dioxide (76%) , Methane (16%) , Nitrous oxide (6%) , Fluorinated Gas (2%)
HOW LONG THEY CAN LAST - Carbon dioxide (half within 100 years, 10% up to 100k) , Methane (10 years) , Nitrous oxide (100 years) , Fluorinated gas (10,000+ years)
WHERE WE CAN FIND THEM -
CARBON DIOXIDE - Cars, coal power plant
METHANE - Cows, rubbish/trash
-
FLUORINATED GAS - Refrigerator, Air conditioning

ECOSYSTEM SERVICES
WHAT ARE ECOSYSTEM SERVICES? - Ecosystem services are benefits that humans receive from the ecosystem. The environment provides living organisms with everything they need to survive (food, light, water and air)
THE 4 S's
SINKS - Processes that absorb our waste. (Example: micro-organisms in oceans break down oil spills).
SOURCE - Natural produces used or that can be converted by us. (Example: turning coal into fuel, using iron ore in manufacturing, timber from natural forests and food sources)
SERVICES - The things that are done for us by nature, producing resources. (Example: forests absorbs carbon dioxide and produces and releases oxygen for us)
SPIRITUALITY - Refers to the personal relationship that human beings have with the environment. (Example: Aboriginal and Torres Strait Islanders having an ancestral connection with their land).

BIODIVERSITY
WHAT IS BIODIVERSITY - Biodiversity refers to the variety of living things on Earth, as well as diversity within and between species, as well as ecosystems. Biodiversity is the foundation of all ecosystem services.

DIRECTIONS 2031
WHAT IS DIRECTIONS 2031?Directions 2031 is an overarching strategic plan for the Perth metropolitan area published by the Western Australian Planning Commission.
ENVIRONMENTAL RESOURCE IMPACTS - Urban sprawl, climate change, water resources
WHAT IS URBAN SPRAWL? Urban sprawl is known to take up a lot of space for housing. Unrestricted growth in many urban areas of housing, commercial development and roads over large expanses of land, with little concern for urban planning.
POSITIVES OF URBAN SPRAWL - More job opportunities around the area, more homes for people to live in, more healthcare, education etc available to locals.
NEGATIVES OF URBAN SPRAWL - Pollution, deforestation and ecosystems (wildlife, plants) loss.

IMPACTS TO WATER
POLLUTION
GROUNDWATER DEPLETION - A term often defined as long-term water-level declines caused by sustained groundwater pumping.
PLASTIC - Plastic waste most likely ends up in wet areas such as the lake, river and the ocean. Plastic can be very harmful towards animals and can potentially kill them or cause very serious injuries. Each bottle can take up to one thousand years to decompose, leaking dangerous and harmful chemicals during the process.
