Answer: C. Freshwater supplies can be depleted in an area.
Water transportation refers to the intentional transfer of water from one geographic location to the other. The methods used to transfer water to long distances includes three categories:
1. Aqua ducts: This includes the transfer of water through pipes, canals and tunnels.
2. Container shipment: This includes transfer of water by using a vehicle or mode of transportation such as tank truck, tank ship and tank car.
3. Towing: This also includes a vehicle to pull water in it's solid form that is ice or in liquid state. Example a tugboat is used to pull an iceberg or pulling a large water bag along with it.
The water being transported by this method is usually from the natural water reservoir native of a land such as lakes, ponds, and rivers. With the increase in the supply and transportation of fresh water will result in depletion of water in the water source of the native land. The native population will not receive adequate water necessary for sustaining life in future.
Therefore, freshwater supplies can be depleted in an area is a cost of using technology to transport water.
