Protecting the Jewel of the North: The Great Lakes Water Quality Agreement
The Great Lakes, a vast network of freshwater holding 20% of the world's surface freshwater, are a vital resource for millions of people and countless ecosystems. Recognizing their importance, Canada and the United States entered into the Great Lakes Water Quality Agreement (GLWQA), a landmark agreement aimed at protecting and restoring the health of the Great Lakes.
First signed in 1972, the GLWQA has undergone numerous revisions and expansions, most notably in 1978, 1987, and 2012. This iterative process reflects the evolving understanding of the complex challenges facing the Great Lakes, from persistent pollutants like PCBs and mercury to invasive species and climate change.
Key Aspects of the GLWQA:
- Shared Responsibility: The agreement emphasizes the shared responsibility of both countries to protect the Great Lakes, acknowledging the transboundary nature of the ecosystems.
- Binational Cooperation: It mandates joint planning, research, monitoring, and implementation of remedial actions to address water quality issues.
- Target-based Approach: The GLWQA sets specific targets for reducing pollution and restoring the ecological health of the Great Lakes.
- Public Participation: The agreement emphasizes public involvement and transparency in decision-making processes.
Achievements of the GLWQA:
The GLWQA has significantly contributed to the recovery of the Great Lakes, leading to:
- Reduced Pollution: Levels of toxic pollutants like PCBs and mercury have declined significantly since the agreement was first signed.
- Improved Water Quality: The overall water quality in the Great Lakes has improved, with better clarity and oxygen levels in many areas.
- Habitat Restoration: Significant efforts have been undertaken to restore degraded wetlands and fish habitats, supporting the recovery of diverse aquatic life.
- Increased Awareness: The GLWQA has raised public awareness about the importance of the Great Lakes and the need for their protection.
Challenges and Future Directions:
Despite significant progress, challenges remain, including:
- Climate Change: Climate change is altering precipitation patterns, water temperatures, and ice cover, impacting the Great Lakes ecosystem.
- Invasive Species: The introduction and spread of invasive species continue to threaten native biodiversity.
- Nutrient Pollution: Agricultural runoff and wastewater discharge contribute to nutrient pollution, fueling algal blooms and threatening water quality.
The GLWQA is constantly evolving to address new challenges. The 2012 update focused on addressing climate change, invasive species, and nutrient pollution. Future efforts will need to prioritize:
- Adapting to Climate Change: Implementing strategies to mitigate the impacts of climate change on the Great Lakes.
- Strengthening Invasive Species Management: Investing in early detection, prevention, and control of invasive species.
- Reducing Nutrient Pollution: Promoting sustainable agricultural practices and improving wastewater treatment infrastructure.
The Great Lakes Water Quality Agreement is a vital tool for protecting and restoring the health of these precious ecosystems. Continued commitment to binational collaboration, science-based decision-making, and public engagement is crucial to ensure the long-term sustainability of the Great Lakes for generations to come.

Exercise: Protecting the Great Lakes
Scenario: Imagine you are part of a local community group in a city on the Great Lakes. You are tasked with organizing an event to raise awareness about the GLWQA and its importance.
Task: Develop a plan for this awareness event. Consider the following:
- Target audience: Who are you trying to reach? (e.g., families, youth, local businesses)
- Format: What type of event would be most engaging for your target audience? (e.g., workshop, film screening, festival, etc.)
- Activities: What activities can you include to educate and inspire your audience? (e.g., guest speakers, interactive displays, art projects)
- Resources: What resources do you need to organize the event? (e.g., volunteers, funding, venue)
Write a brief proposal outlining your event plan.
Exercice Correction
This is an open-ended question and there are many possible solutions. A good answer would include a clear plan for the event, addressing the points mentioned in the task. For example:
Event Proposal: "Great Lakes Day"
- Target Audience: Families with children, local residents interested in environmental issues.
- Format: Outdoor festival with booths, activities, and live entertainment.
- Activities:
- Interactive booths explaining the GLWQA, its achievements, and challenges.
- Art activities for children related to the Great Lakes ecosystem (e.g., painting, drawing, building model boats).
- Educational games on water quality, invasive species, and climate change.
- Live music by local artists with environmental themes.
- Guest speaker from a local environmental organization sharing success stories about the Great Lakes.
Resources: * Volunteers from the community group and local environmental organizations. * Funding from local businesses and grants. * Venue: Local park with ample space for booths and activities.
This is just one example, and your plan can be tailored to your specific community and resources.
