Final answer:
Humans use innovative techniques in agriculture to overcome challenges posed by physical environments and climates.
Step-by-step explanation:
Three examples of humans using innovative techniques to practice agriculture in otherwise unsuitable physical environments and climates are:
- Vertical farming on a small Caribbean island: This technique allows for the cultivation of crops in a limited space, making it suitable for islands with limited arable land.
- Building a fish farm in a river that cuts through a desert: This technique utilizes the available water source in a desert region to sustain the fish farm and provide a source of food.
- Greenhouse usage in the northern region of Norway: Greenhouses create a controlled environment, enabling the cultivation of plants in areas with cold temperatures and limited sunlight.
