It may result in soil erosion and animal and plant habitat loss, which will eventually result in the extinction of sensitive species. Climate changes and ecosystem instability may result from it.

(i) Unleaded gasoline causes less pollution because it doesn't discharge lead compounds from exhaust fumes into the atmosphere.
(ii) Enables the catalytic converter to continue functioning, whereas the catalyst in the converter is deactivated by the lead in leaded gasoline.
