Food production has no environmental impact

Populations are shrinking everywhere

Recycle, reuse, reduce

Reduce, reuse, recycle

Recycling is illegal

Reducing prevents the waste and avoids the resources and energy recycling still uses

Reducing produces more waste overall

Recycling uses no energy at all

It releases methane and can pollute soil and groundwater

It recovers all the energy in the waste

It turns plastic into compost quickly

It uses no land

Burns it to recover energy

Buries it deep in landfill

Lets decomposers turn it into a useful soil improver

Ships it to the ocean

It biodegrades within days

It is durable and does not biodegrade, so it builds up and harms wildlife

It dissolves harmlessly in seawater

It is a renewable energy source

Using up resources as fast as possible

Meeting present needs without compromising future generations

Stopping all development everywhere

Only building new factories

The size of a person's actual feet
