Grass isn’t much of help in generating Oxygen; only trees with lots of leaves produce sizeable amount of Oxygen which are rare in amount in Golf Courses
Eats up Freshwater Resources
Golf courses require an enormous amount of water every day and, as with other causes of excessive extraction of water, this can result in water scarcity.
An average golf course in a tropical country such as Thailand uses as much water as 60,000 rural villagers
If the water comes from wells, overpumping can cause saline intrusion into groundwater.
Golf resorts are more and more often situated in or near protected areas or areas where resources are limited, exacerbating their impacts.
Pollutes Soil
An average golf course in a tropical country such as Thailand needs 1,500kg of chemical fertilisers, pesticides and herbicides per year
