Coastal erosion is one of the main causes behind global warming.

This phenomenon leads to massive loss of land and sea alike. Every year, millions of acres of land lose to coastal erosion around the world.
Coastal erosion occurs due to a number of different factors. Sometimes it happens as a result of changing sea levels or changing weather patterns. Coastal erosion can also be caused by natural biological processes like tidal currents, storms, fog, and rain. Another major factor that contributes to coastal erosion is the excessive harvesting of marine life by coastal owners.
However, not all erosion is due to natural processes. Some cases of coastal erosion are caused by human activities like building new houses, digging canals, laying mines, dredging, and constructing oil rigs. Even changing the land’s drainage system can cause Coastal erosion. All these processes together can result in massive loss of land to coastal erosion.
Sedimentation of land takes place when soil is pushed inland or carried out to sea. Sediment can occur in the form of run off, washed away into nearby water, to the base of tributaries, and can even be transported further inland. When sediments reach the ocean, they cause an environmental problem called an algal bloom.
