Which is a sustainable practice?
O wind farms
o clear cutting
O flood irrigation
O overfishing

WIND FARMS

- Flood irrigation uses more water than necessary, drip irrigation is better.

- Clear cutting is not necessary, nor is it practical. Logging should instead be done using methods that create sustainable yield--which ensures that no more is harvested than can be naturally replenished (Dadd)

-A sustainable fishery is one that is harvested at a sustainable rate to ensure that the fish population does not decline over time as a result of fishing methods or practices. ... Overfishing, as well as issues such as individual fishing quotas and the curtailment of destructive and illegal fishing practices are addressed.
