Over-fishing, pollution, and introduced species.
What you are allowed to do in a 'marine national park' depends on what country and state/province the park is in as the rules - and the actual names - vary a lot from place to place. In Australia the different types of parks or 'protected area' include: marine national parks, marine reserves, marine sanctuaries, marine conservation areas, marine management areas, marine reserves, marine reserve areas and marine parks. Most marine protected areas have rules that limit or prohibit activities that impact on the marine animals and plants in a way that is inconsistent with the reason the protected area was set up. For example - compare different types of marine parks in NSW, Victoria and Western Australia.
The weather in a marine area is dependent on where the marine area is located on the globe. Northern marine areas tend to have cooler water than southern marine areas. There is also a problem with hurricanes in all marine areas, except the North and South Poles.
Tides can cause changes in sea level, affecting coastal areas and shorelines. They can also influence ocean currents and affect marine ecosystems and habitats. Additionally, tides can impact navigation and marine activities.
A seal wall in a marine environment serves to protect coastal areas from erosion caused by waves and tides. It helps to maintain the stability of the shoreline and prevent damage to infrastructure and property.
The White Island eruption in December 2019 caused multiple fatalities and injuries among tourists who were on the island at the time. It also led to significant damage to the island's ecosystem and surrounding marine environment. Additionally, the eruption prompted discussions about safety regulations for tourist activities in volcanic areas.
increasing population of people leads to larger urban areas, which often leads to destruction or damage to the surrounding environments
it accounts for 140 million jobs in fishing and many more indirect activities like:distribution of sea food,shipping,tourism,sea mining,marine military activities,science related activities and leisure activities.

China has a number of marine protected areas all over the country. Some of these include the Liyashan National Marine Park in Jiangsu, the Xiamen National Marine Park in Fujian, and the Hailingdao National Marine Park in Guangdong.
A maritime location is an area near or related to the sea/ocean. It typically refers to places that are connected to marine activities, such as coastal areas, ports, or ships on the water.
People pollute coastal areas through various activities, including industrial discharges, agricultural runoff, and improper waste disposal. Plastic waste, such as bags and bottles, often ends up in oceans, harming marine life and ecosystems. Additionally, oil spills and sewage dumping can lead to significant environmental damage. These pollutants not only degrade water quality but also affect the health of coastal communities and wildlife.
