Answer:

1. ecological balance of coral reef

2. overharvesting

Answer 2

Answer:

Destruction of coral reef is caused by dynamite fishing and muro-ami, while mangrove destruction is caused due to over- exploitation , deforestation, pollution, land reclamation and conversion of mangrove forest area into other uses.

Explanation:  

Destruction of coral reef is caused by dynamite fishing and muro-ami

Corals grow in coastal and marine habitats that serve as strong foundations for marine animals to stabilize and grow.

Dynamite Fishing  

• One of the most dangerous fishing methods is Dynamite fishing. It includes the use of an explosive device similar to dynamite to catch fish.
• This dynamite usually kills fish or even scares them. It not only kills fish but also disrupts the natural balance of the water by disrupting the coral reefs or their colonies.

Muro-ami

• Muro-ami is a fishing method used in coral reefs in Southeast Asia. It uses a rotating net and power gripping equipment.

• These usually involve large stones attached to ropes thrown into coral reefs.
• The pounding devices were violently lowered to the area around the net, smashing the coral reefs into smaller pieces to scare the fish.

  Causes of mangrove destruction

• Mangrove trees are grown in tropical region. Most of the mangrove forests areas are under threat.

• Sea level rise and coastal erosion: Due to global warming, sea levels are steadily rising. Rising sea levels have washed away large areas of mangrove forests.

• The depletion of river water due to dams has led to the destruction of mangroves.

• Deforestation: Large forests have been cleared for agricultural land, human settlements, industrial areas, aquaculture. As a result, the mangroves become extinct. 2-8 percent per year.

• Over-harvesting: They are also heavily exploited for firewood, woodworking and pulp production, coal production, and animal fodder.

• Destruction of coral reefs: Coral reefs provide the first barrier against strong waves and waves. When destroyed, even the strongest waves that reach the shoreline can flood the mangroves.

• Pollution: Mangroves also pose a significant risk due to fertilizers, pesticides, and industrial effluent transmitted by river systems.

• Climate change: Extremely low rainfall and extremely high sea temperatures and high temperatures pose a serious threat to the survival of mangrove forests.
• Mangroves play a role in preserving coastal ecosystem. Due to human activities that cause natural imbalance and lead to destruction of mangroves.
