Question

global food system supplies dragonfruit and caviar by ship instead of plane, keeping the distance the same. Which choice lowers gases the most?
a. Larger ships carrying mixed cargo
b. Longer shelf storage times
c. Extra insulation during storage
d. Slower transport per unit

To determine which choice lowers greenhouse gas emissions the most when transporting dragonfruit and caviar by ship instead of plane, we need to analyze each option:

a. Larger ships carrying mixed cargo: Larger ships are generally more fuel-efficient per unit of cargo transported compared to smaller vessels. However, this option focuses on the efficiency of the ship itself rather than the overall carbon footprint during transport, which may not significantly reduce emissions in isolation.
b. Longer shelf storage times: While extending shelf life can reduce waste and the need for frequent shipments, it does not directly influence the transportation emissions itself. It merely delays the need for shipping but does not mitigate the emissions produced during transport.
c. Extra insulation during storage: Enhanced insulation can help maintain the temperature of perishable goods during storage, potentially reducing spoilage. However, it does not affect emissions from transportation and is more related to minimizing waste rather than lowering transportation-related greenhouse gases.
d. Slower transport per unit: Slower transport methods, which would be more applicable when using ships instead of planes, typically reduce fuel consumption in relation to distance traveled. Ships are more efficient at lower speeds, and a slower transit allows for less frequent trips, thereby collectively lowering the overall greenhouse gas emissions per unit of cargo despite the longer travel time.

In summary, option d. Slower transport per unit is the choice that most effectively lowers greenhouse gas emissions associated with transporting dragonfruit and caviar by ship instead of plane.
