Question

The Jones family of Jacksonville would like to live more sustainably by reducing their fossil fuel use. They already carpool and have reduced their electricity use. In addition to what they are already doing, which of the following would be most helpful in further reducing their fossil fuel use?

Removing most of the grass in their yard and replacing it with a vegetable garden.
Consuming more farm-raised beef and reducing the amount of vegetables they eat.
Fertilizing their yard more frequently and watering to encourage grass to grow.
Planting exotic shade plants in their yard and hiring a lawn care company to tend them.

Answer 1

D. Planting exotic shade plants in their yard and hiring a lawn company to tend to them.

Step-by-step explanation:

Both grass and vegetables produce CO2. Vegetables produce as much CO2 as a car that's been driving 4.5 miles. Beef produces enough CO2 for 63 miles. This eliminates all of the answers except for D. Plants use CO2 in photosynthesis and give off O2. So not only will is reduce the CO2 output, it will provide you oxygen.
