What is sustainability?

• meet the needs of the present

• without damaging consequences of future generations

• using renewable resources

• all choices are correct

Best definition of sustainable is .....

• Sustainability ­ using resources in a way that meets the needs of the future generation without having particularly damaging consequences on current generations.

• Sustainability ­ using resources in a way that meets the needs of the current generation without having particularly damaging consequences on future generations. Making products sustainable means you would need to use renewable resources.

• Sustainability ­ using resources in a way that meets the needs of the current generation without having particularly damaging consequences on future generations.

A “biodegradable” product has the ability to.....

• break down, by biological means, eg bacteria or enzymes.

• break down, overtime, by biological means, eg bacteria or enzymes.

• rot away naturally in the environment

• break down, safely and relatively quickly, by biological means, eg bacteria or enzymes.

Non renewable is

• coal, oil and gas and once they are used they can not be replaced in our lifetime.

• fossil fuels as once they are burnt they are gone

• coal, and oil, once they are used they can not be replaced in our lifetime.

• biofuels, corn and methane and once they are used they can not be replaced in our lifetime.

Renewable energy, is ........

• when the resource can be replaced, eg, wind, solar, tidal, biomass (plants)

• when the resource can be replaced in our lifetime. eg, wind, solar, tidal, biomass (plants)

• when the resource cannot be replaced in our lifetime.

• when the resource can be replaced in our lifetime. eg, wind, solar, tidal,

Coca-Cola's new biodegradable PlantBottle Technology is to replace .....

• PET

• PE

• PP

Bioplastics are made from

• natural materials such as corn starch

• traditional petrochemicals, which are engineered to break down more quickly

• simply plastics made from recycled plastic materials rather than raw petrochemicals.
