Portugal is a country located on the western coast of Europe, bordered by the Atlantic Ocean to the west and south. The ocean plays a significant role in Portugal’s culture, economy, and lifestyle. With its long coastline and beautiful beaches, Portugal is a popular destination for surfing, sailing, and other water sports. The ocean also provides a rich source of seafood, which is a staple in Portuguese cuisine. Additionally, Portugal has a long history of seafaring and exploration, with famous explorers such as Vasco da Gama and Ferdinand Magellan setting sail from Portuguese ports to discover new lands across the ocean. Today, Portugal continues to be a maritime nation, with a strong fishing industry and a thriving tourism sector centered around its coastal attractions.
1. Overfishing: The practice of catching fish faster than they can reproduce can lead to a decline in fish populations and disrupt the balance of marine ecosystems.
2. Pollution: Pollution from various sources, including plastics, chemicals, and oil spills, can harm marine life and habitats, as well as contaminate seafood that humans consume.
3. Climate change: Rising sea temperatures, ocean acidification, and sea level rise caused by climate change can have detrimental effects on marine life and ecosystems.
4. Habitat destruction: Activities such as coastal development, bottom trawling, and coral reef degradation can destroy important habitats for marine species.
5. Invasive species: Species that are introduced to new environments can disrupt the balance of native ecosystems and outcompete native species for resources.
6. Illegal fishing: Illegal fishing practices, such as poaching and overfishing in protected areas, can deplete fish stocks and harm marine ecosystems.
7. Plastic pollution: Plastic waste, such as bags, bottles, and microplastics, can harm marine life through entanglement, ingestion, and habitat destruction.
8. Noise pollution: Human activities, such as shipping, sonar, and drilling, can create excessive noise in the ocean that disrupts marine animal communication and behavior.
9. Ocean acidification: Increased levels of carbon dioxide in the atmosphere can lead to ocean acidification, which can harm marine organisms that rely on calcium carbonate to build shells and skeletons.
10. Coral bleaching: Rising sea temperatures and pollution can cause coral reefs to expel the algae that give them their color and nutrients, leading to coral bleaching and eventual death.
