Study Notes

Environmental Sustainability Definition

Environmental sustainability involves responsibly managing natural resources to maintain them for future use.
This includes limiting resource usage and preventing resource degradation, like reducing water consumption and avoiding pollutants in water.
Education plays a crucial role in sustainability, as individuals often misuse resources due to lack of knowledge.
Sustainable practices are vital for the entire biosphere (oceans, land, atmosphere) and counteract issues like climate change, caused by excess greenhouse gas emissions that damage natural resources.
Other problems such as deforestation, habitat loss, species extinction, overfishing, and water waste stem from unsustainable resource use.

Environmental Sustainability Examples

Renewable energy sources (solar, wind, hydroelectric, biomass) provide a sustainable alternative to non-renewable resources.
Recycling metals and minerals reduces the need for mining, which often causes environmental damage.
Sustainable agriculture practices include crop rotation (using legumes to maintain soil quality) and cover crops (planting during off-seasons to prevent erosion).
Selective logging in forestry involves only removing select trees, allowing the forest to recover.

Renewable vs. Non-Renewable Resources

Renewable resources can be replenished faster than they are used; non-renewable resources cannot.
Examples of renewable resources include solar, wind, and well-managed forests.
Examples of non-renewable resources include fossil fuels (coal, oil, natural gas).
Unsustainable resource management can transform renewable resources into non-renewable ones.

Environmental Sustainability Objectives

Sustainable development is the primary goal: using resources sustainably without hindering economic growth.
Planetary boundaries (maximum resource degradation limit) must be respected.
Globally and locally, resource management is crucial.
Regulations (like the Clean Air Act, Clean Water Act, and Paris Agreement) safeguard human health, economic growth, and the environment.

Environmental Sustainability Policy Example

Policies like the Australian Government's Department of Human Services policy aim to adhere to regulations, manage resources, reduce pollution, and utilize renewable energy.
This involves environmentally responsible practices, like recycling, water conservation, and renewable energy use in government operations.

Applying Environmental Sustainability

Sustainability is crucial in agriculture, forestry, and energy sectors.
These industries heavily rely on natural resources and impact the environment significantly.

Sustainable Agriculture

Industrial agriculture often damages the environment through monocropping, leading to soil degradation, erosion, and water pollution from fertilizers/pesticides run-off.
Sustainable agricultural practices combat these damages.
Crop rotation, using legumes, helps restore soil nutrients and reduce fertilizer use.
Cover crops protect soil from erosion during fallow seasons. Modern irrigation systems optimize water use.

Sustainable Forestry

Logging, a necessary source of timber, can be sustainable.
Clear-cutting is unsustainable, while selective logging (taking only mature/valuable trees) preserves the forest.
Forest protection involves wildfire management and regulating wildlife populations.

Sustainable Energy

Growing global energy demand can be met by embracing renewable energy (solar, wind, hydroelectric, and biomass energy) rather than depleting non-renewables.
Technologies like solar panels, wind turbines, dams, and biofuel production convert renewable resources into usable energy.
