Rubber, Tropical Plants, Petroleum, & Natural Gas

Rubber, elastic substance obtained from the exudations of certain tropical plants (natural rubber) or derived from petroleum and natural gas (synthetic rubber). Because of its elasticity, resilience, and toughness, rubber is the basic constituent of the tires used in automotive vehicles, aircraft, and bicycles.

If plastic comes from oil and gas, which come originally from plants, why isn't it biodegradable?
