Sustainable development

Meeting current needs without harming future generations

Resource depletion

Using natural resources faster than they can be replaced

Nonrenewable resources

Resources that cannot be replaced like fossil fuels

Renewable resources

Resources that can be replaced but can still run out if overused

Examples of resource depletion

Mining deforestation soil erosion overfishing aquifer depletion

Aquifer depletion

Using groundwater faster than it can refill

Industrial agriculture impact

Uses lots of water and causes resource depletion

Mass consumption

Large amounts of goods used by people especially in wealthy countries

Problem with mass consumption

Uses resources quickly and is not sustainable long term

Environmental pollution

Harmful contamination of air water and land

Point source pollution

Pollution from one specific source like a factory or pipe

Nonpoint source pollution

Pollution from many spread out sources like runoff

Examples of point source pollution

Factories smokestacks wastewater discharge

Examples of nonpoint source pollution

Farm runoff city streets parking lots

Climate change

Long term changes in global or regional climate

Cause of climate change

Increase of CO2 mainly from burning fossil fuels

Carbon dioxide role

Traps heat in atmosphere and warms Earth

Industrialization effect on climate

Increases CO2 levels and global temperatures

Mauna Loa CO2 measurements

Show steady increase in CO2 since 1958

Consequences of climate change

Rising temperatures changing weather patterns environmental damage

Sustainable solutions

Ways to reduce environmental damage from industrialization

Conserving natural resources

Using fewer resources and reducing waste

Ways to conserve resources

Reduce reuse recycle improve efficiency

Recycling

Turning used materials into new products

Cogeneration

Producing two forms of energy from one fuel source

Reducing pollution

Using laws and technology to limit contamination

Clean Air Act

US law that limits air pollution

Clean Water Act

US law that limits water pollution

Pollution control in developed countries

Stricter laws and better technology reduce pollution

Pollution in developing countries

Less strict laws lead to more pollution

Renewable energy sources

Energy that can be replenished like wind and solar

Examples of renewable energy

Wind solar hydroelectric

Benefits of renewable energy

Less pollution and sustainable long term

Carbon neutrality

Balancing CO2 emissions with removal to have no net increase

How to reach carbon neutrality

Reduce emissions and remove carbon from atmosphere

Carbon removal

Taking CO2 out of the atmosphere

Ecotourism

Tourism focused on protecting environment and helping local people

Benefits of ecotourism

Protects nature creates jobs supports local communities

Limits of ecotourism

Can still harm environment if too many tourists

Sustainable Development Goals (SDGs)

Global goals by the UN to improve life and protect the planet

Purpose of SDGs

Reduce poverty protect environment and promote sustainability

Industrialization impact overall

Raises living standards but harms environment

Main idea of module

Industrial growth causes environmental problems but solutions can reduce harm
