Large, durable plastic use is less of a concern, if I understand correctly. Plastic use around food (and packaging in general), for instance, has a lifespan of approximately 6 months. Compare to the 13 years for plastics used by the automotive industry.
There's TONS of packaging that could be replaced by other materials -- particularly materials that can non-toxically decompose in the environment in a reasonable time frame.
