Commercial trawling has a devastating effect on biodiversity in areas where it has been used. Large commercial trawlers have been historically decimating both marine environments and significantly decreasing stock levels to a level at which they are unable to recuperate. The impact on communities sitting on the seafloor, known as benthic communities is devastating, the primary culprit being drag trawlers with beams of up to 12 meters, and several beams often deployed at the same time. This lesson looks at the effect of commercial trawling on both fish stocks and benthic community biodiversity. Students will understand relative sizes and impacts of large-scale fishing operations, and devise a plan to reduce the impacts of trawling. Students perform percentage calculations and analyze graphs.
In everyday life, students can be unaware of the impact of their food choices on the environment. Therefore, it is essential that students are educated in their food choices. If students cannot link their food to where it comes from, they are unlikely to make sustainable choices in the future. “Go Fish” aims to encourage students to start thinking about fish in the ocean and how fish stocks can change for the better or for the worse. In the educational game, cards will be selected by chance, so some students ‘oceans’ may be more successful than others. Students will complete a fishing log to monitor events of the game and reflect on the events that cause a change. By playing this game, students can come aware of the negative and positive actions that can take place to encourage fish stocks or declining fish stocks.
A fishery is a geographic region that contains a population of aquatic species which are a natural resource that needs to be managed. This management requires people from different backgrounds and in different fields, such as stakeholders, scientists, fisherpeople, government groups, and citizens. The goal of managing fisheries is to ensure that the different fish populations will be sustainable and a resource for now and future use. It can be a difficult thing to manage since people in different roles will have different priorities. Students will re-enact a fisheries management meeting by adopting the roles of various stakeholders in Plymouth (commercial fishers, recreational fishers, environmental groups, citizens, scientists, etc.) and advocate for a certain policy based on their role as a stakeholder.
For educators looking to teach biodiversity to their students. Lead students from the basics of biodiversity to building solutions to foster and protect this element of our world.
This calendar has been created by the EarthEcho International Youth Leadership Council. These youth, aged 16-22, designed this calendar to increase awareness and inspire behavior change to protect our collective future. The YLC invites you to use this calendar track and change your habits and, hopefully, provide monthly ideas to help you live a more sustainable, conscientious lifestyle.
Students will follow the engineering design process to explore solutions to the overwhelming plastic packaging problem. They will develop sustainable designs that will consider alternatives to plastic packaging in items like juice boxes, plastic straws, bin liners, and single-use take-away/take-out containers.
In this investigation, students design and create a Recycling Sorting Machine to eliminate the amount of waste that is incorrectly being sent to landfill. Students use basic resources (recycled and/or reused items in the classroom, home, or their community) to engineer a solution to the growing problem of waste in our schools.
As the name suggests, microbeads are very small (microscopic) beads of plastic. Since they are particles of less than 1mm, they are almost impossible to capture as they enter household drains. This leaves these small, solid balls of plastic to enter our aquatic ecosystems where they are ingested by organisms and accumulated within the food web. In this activity, students are challenged to design and construct their own device to extract microplastics from cosmetic products such as facial cleansers, body wash, and toothpaste.
In this investigation, students describe the life cycle of man-made products that include or originate from plastic to evaluate how they may impact the environment. Students use a basic life cycle assessment – similar to assessments used by process engineers – that allows them to identify and order the different steps in the life cycle of a product. Using their analyses to compare the impacts of different products, students develop ideas to reduce the environmental impact of the production process or lifecycle of the product.
Students examine the nature of the problem and work collaboratively to create solutions to the issue of nurdles becoming evermore present in our oceans. Nurdles are small plastic resin pellets which are used to make many of the plastics we use every day. Unfortunately, they end up where they are not supposed to and cause a wide range of problems. Nurdle Know-How is a series of activities that will ultimately prepare students to design and build a nurdle capture system to clean up their local bay, harbor, or coastal waters.
