Final answer:
The statement indicates that organic spinach yields a higher net return than other crops. Although organic farming has higher production costs, it is supported by organizations for its sustainability and environmental benefits.
Step-by-step explanation:
From the provided information stating 'organic spinach > net return,' we can conclude that organic spinach has a higher net return compared to other crops. The symbol '>' is commonly used in economics to indicate 'greater than,' so the conclusion A) Organic spinach has a higher net return compared to other crops is the correct interpretation of the statement.
It's important to note that switching to organic farming can lead to an increase in supply of organic produce, as seen by the shift of the supply curve to the right. However, the production costs for organic farming, particularly for inputs like organic fertilizers and pest management techniques, tend to be higher than conventional farming, which could impact net returns.
Moreover, the organic food movement is supported by the UN's Food and Agricultural Organization due to its environmental benefits and sustainability.
