Answer:
1. The coastal erosion
The activity of ocean waves and ocean currents can lead to the coastal erosion where this activity is a continuous erosion of coastal land through the waves and ocean currents. This natural phenomenon can also result in the descent of land so that the land appears lower than the oceans. Of course, this phenomenon can increase the risk of the overflowing sea water to the mainland (flood).
2. The shrinking of coastal region
The first real impact on coastal erosion is the shrinking of the coastal region. The activity of the sea waves that hit the coastal area can continuously take off about 5-10 meters from the beach.
In addition, the continuous abrasion that hit the coast will also inundate areas that were once a residential population or tourism sector. This is very detrimental and endangers the sustainability of the population and business in the tourism sector. Read more about Main Elements in Ocean Water
3. The damage of Mangrove Forest
The damage of mangrove forests also has the potential to increase the risk of coastal erosion. If mangrove forests have been damaged, the coastal abrasion can no longer be mitigated. The damage of mangrove forests usually occurs during the hurricane season.
The destruction of mangrove forest can also occur due to the massive sand mining in high intensity. If the balance of the ecosystem has been damaged, and the sea has lost its sand supply. Both of these need to be addressed more intensively to reduce the risk of coastal erosion.
4. No more habitat for fishes
It is not only humans who do not have the shelter, the erosion of coastal areas can also cause fish on the coast to lose their habitat.
if the coral reefs mined to be used as souvenirs. The fishes are along the shoreline will lose their habitat, because of the predatory threats, the unsuitable of the sea water temperatures and the big of sea waves. The worst thing is, these fishes will die and it can certainly harm fishermen who want to catch the fishes. Read more about Fishes in Atlantic Ocean
5. The global warming
The global climate can also increase the potential of the abrasion on the shorelines. The increasing of the temperature of the earth can melt the poles where this causes an increase in the sea level rise. This rising sea level is the cause of the abrasion on the shorelines.
This climate change can also cause the high waves and storms. The climate change also can reduce the number of the fishes and shrimps populations in the sea. Read more about How to Reduce Global Warming Effects in Ocean
6. The sand mining on the shorelines
Abrasion on the shoreline can also occur due to human intervention. Some people legally mine on the sand on the coastal areas upstream that empties into the coastal area. This sand mining activity will make the coastal position lower than the sea. The result of abrasion of the sand mining can also erode the coastal areas for as far as tens of kilometers.
In addition, due to sand mining also impact on the village road because it will suffer damage. Roads in the village of manufacture are not as solid as the highway. While the vehicle carrying sand every day through the village. This heavy vehicle that causes the road to the village to be damaged.
7. The construction on the adjacent coastal areas
Who does not like to travel beach, surely everyone likes it, right? Every time that we visit the beach we also find many hotels or residential areas nearby the shorelines. This human factor is the one that influences of coastline changes. The construction of settlements and tourist attractions can lead to more severe abrasion.

Especially with the rising of the several tourism accommodation developments such as hotels, resorts and villas are also the main cause of abrasion. If the development around the coast is not restricted, the water will overflow and it can enters. Even it can destroy the residence of some residents who live at the coastal areas.
8. The construction of ponds that do not productive and conducive
Deforestation of mangroves is usually done to be converted into ponds. Even sometimes the land used to build a pond is not productive and conducive. This is what causes the pond area will have a negative impact on the coastline.
Gradually abrasion will erode coastal areas, even this phenomenon can destroy homes and even turtle conservation sites in it. The unconsciousness of the community about the dangers of unproductive pond land is a big problem. Until now the ponds are located in an environment that is not conducive is still a pro and cons in the society.
