Human impacts
Human uses of coasts
An increasing part the global population inhabits coastal regions. Many of the world's major cities have been built on or near good harbors and have port facilities. Jurisdictions that are landlocked have achieved port status by such measures such as building canals.
The coast is a crucial frontier and must be defended against military invaders, smugglers and illegal migrants. Fixed Coastal defenses have long been erected in many nations and coastal countries also require a navy and some form of coast guard.
