- It produces oxygen,
- filters rainwater,
- cools the air,
- is a useful home to plants and wildlife.
- adds to global warming. Heat from sun is reflected back into atmosphere rather than being absorbed into the ground
- leads to large amount of disinfectant being added to the soil. Cleaning off the blood, sweat and spit from artificial turf requires disinfectant and detergent where as these materials are easily absorbed and broken down by natural soil
- disposal of the artifical surface is a real problem. Goals plan to replace surfaces every 7 years yet we know that they are very real problems with disposing of the old surfaces as they don't disintergrate. Some landfill sites in America have banned them.
