· This impacts the bottom line of governments that collect sales taxes. In addition, unsafe (or questionable) bridges often result in higher insurance premiums and expose municipalities to the risk of costly lawsuits resulting from accidents and injuries. This is another key driver of government spending on bridge maintenance.
· Openpit mining produces eight to 10 times as much waste as underground mines because a greater amount of topsoil, overburden and barren or waste rock has to be removed. Gold mining in South Africa over the centuries has resulted in the accumulation of thousands of voluminous tailings dumps which are stered all over the country with lots of potentially negative impact on the .

For mining purposes, big machines are often used in order to make the mining process more effective and to reduce the physical work for miners. However, these machines emit large amounts of harmful gases, also including greenhouse gases like methane or CO2. Thus, mining can also cause air pollution and the implied consequences.
· Main potential impacts on seagrasses from dredging and sand mining include physical removal and/or burial of vegetation and effects of increased turbidity and sedimentation. For seagrasses, the critical threshold for turbidity and sedimentation, as well as the duration that seagrasses can survive periods of high turbidity or excessive sedimentation vary greatly among species.
