Answer:
A large increase in human population.
Explanation:
Your question isn't complete, but I'll give you an explanation to help you out.
- Since you said that the area that measures 3,000m² requires 2 workers for fertilizer application, then this means that 1 worker will be able to work on an area of (3000m²/2) = 1500m².
- Now, let's assume that the total land area which wasn't provided is 45000m². Then, the number of workers that'll be required will be:
= 45000m²/1500m² = 30
Therefore, 30 workers will be required for 45000m² of land area.
