include social, environment and economical factors
social: Not always the most attractive looking material. Some concretes and cements create a gloomy and depressing atmosphere. Environmental: Concrete and cement release green house gases. Concrete/cement footpaths over up natural soils and leave less room for trees to be planted and less natural earth for insects to live in. Economic: Expensive to remove and dump. In some cases, some cement foundations are so deep they are impossible to remove, meaning the land they're on cannot be used for much else, decreasing the land resources in the economy
