The amount of algae growth required for powering America's fleet of vehicles would cover every ocean and kill every single fish on the planet.

Land-based farms require pumping water, maintenance, energy, etc. If you build them in the desert, you suffer horrendous water losses. If you build them near the ocean, you encroach on livable and arable land.
