UO_Using the Ocean - What's the Point? Module Review

Oceanography module Review

In this module, we discussed how humans use the ocean for food, energy, mineral extraction, transportation, and recreation. However, these activities can lead to overfishing, pollution, habitat destruction, and increased carbon emissions, posing serious threats to marine biodiversity and the overall health of ocean ecosystems. To mitigate these negative impacts, sustainable fishing practices, pollution regulation, renewable energy promotion, stricter maritime and trade regulations, and global cooperation on ocean conservation are necessary. Education and community involvement are also crucial in promoting conservation efforts and sustainable use of ocean resources.

Let's review the keywords and main points of the module.

  1. What are the primary ways in which humans use the ocean, and what benefits do these activities provide? 
    • Humans use the ocean for food through fishing and aquaculture, for energy via offshore drilling and renewable resources, for mineral extraction through activities like deep-sea mining, and for transportation and trade with ships that carry global commerce. Additionally, oceans are central to recreation and tourism, offering activities such as boating, swimming, and diving. 
  2. How do these activities impact the marine environment, and what are the potential consequences if these impacts are not managed? 
    • These activities can lead to overfishing, pollution, habitat destruction, and increased carbon emissions, which collectively pose serious threats to marine biodiversity and the overall health of ocean ecosystems. Unmanaged impacts can result in the depletion of fish stocks, loss of biodiversity, and degradation of ecosystems, which are crucial for maintaining the balance of marine life and the global environment. 
  3. What strategies can be implemented to mitigate the negative impacts of human activities on the ocean? 
    • Strategies include enforcing sustainable fishing practices, regulating and monitoring pollution, promoting renewable energy sources, implementing stricter maritime and trade regulations, and enhancing global cooperation on ocean conservation. Education and community involvement are also vital in promoting conservation efforts and sustainable use of ocean resources. 

In this module, we studied the following topics:

  • Lesson 1 Introduction to Humans & The Ocean   
    • This lesson explores the various ways humans utilize the ocean, such as sourcing food, producing energy, extracting minerals, enabling global trade, and fostering tourism. In addition, it emphasized the necessity of responsible stewardship to ensure that we can continue to benefit from the ocean's resources while minimizing environmental impacts and preserving its health for future generations.
  • Lesson 2 Alternative Energy   
    • This lesson explored four main types of ocean energy: tidal, wave, ocean thermal energy conversion, and salinity gradient energy. Each has unique mechanisms and suitable applications, and ongoing research aims to reduce environmental impacts and increase efficiency. 
  • Lesson 3 Recreation and Transportation  
    • This lesson explained how oceanic recreational and transportation activities impact marine ecosystems through chemical and noise pollution, physical disturbances, and direct harm to wildlife. Understanding these impacts helps us to develop and advocate for effective mitigation strategies that protect our marine environments while allowing sustainable human activities.
  • Lesson 4 Policies and Laws 
    • This lesson explored the crucial role of tides in the ocean, driven by lunar and solar gravitational forces and their influence on chemical, biological, and geological ocean systems. We also delved into tidal energy, highlighting its potential as a sustainable resource and the importance of balancing energy conversion with environmental considerations. 

  • Lesson 5 Sustainability Plan
    • In this lesson, we outlined the key components of a sustainability plan focused on ocean conservation and how these plans may differ based on proximity to the ocean.
