All of the following statements are true except a-recycling petroleum-based products conserves resources b-air quality is important everywhere, not just in large cities c-human activity is limited by the availability of resources d-alternative energy sources are often too impractical to use

The correct answer is D- alternative energy sources are often too impractical to use

Explanation:

Alternative energy sources are practical in terms of the source of the energy, alternative energy like solar, wind and Hydroelectric use Renewable resources, this means the resources are naturally formed (like water) and they can be used over and over by being cautious of not using them faster than they are generated.

This makes Alternative energy sources way more practical than traditional ones that use non-renewable resources like petroleum or coal. These traditional sources give the most amount of energy with the lower costs and used resources but looking at the damage they do to the environment and being non-renewable makes them highly unpractical.

Contrary to popular belief petroleum-based products can be recycled through refineries.
