Approximately 600,000 sea birds die each year by getting caught on hooks used in line fishing. A device called the Hookpod, invented by a UK company in Devon, has a clever solution to this problem. The fish hook is covered by a case so birds cannot get hooked. At a certain depth (below the diving depth of indigenous birds) a mechanism is triggered to release the case which floats to the surface and is retrieved to be used again. These lesson ideas provide an interesting practical idea to use a particle model to explain density and pressure in a gas. Students will then take part in a STEM design challenge to make a device to respond to a pressure change at a particular depth of water.

Seafood serves as a primary source of food and protein for many people across the world, and the economies of many nations are heavily influenced by fish stocks and fisheries management. While efforts are in place to manage fisheries in many places around the world, there are still risks associated with fishing on a commercial scale. Many fishing vessels are equipped to target specific species of fish, for example, cod, but the large nets and trawls used for efficiency have a downside. This downside is called “bycatch”. Bycatch is defined as any non-targeted species that are brought in accidentally within the catch. In this lesson, students will use the engineering design process to create an alternative to modern fishing nets to try and reduce the amount of bycatch. They will also practice data collection and review.

Philippe Cousteau explores juvenile fish habitats. Marine biologists, Tom Stamp, and Dr. Ben Ciotti show Philippe how different habitats can be monitored. The use of nets, acoustic telemetry, sampling and more are used to monitor habitats, like estuaries. Learn how protecting these habitats, where fish spend their early years, is crucial in ensuring fish populations for future generations.

Fish are a major food source for many of the world’s population, however, many fishing practices can be detrimental to the environment. One of these negative impacts is called by-catch. Philippe travels to the Plymouth Fishmarket to learn about quotas and how this can impact fish populations. Different fish species have different life cycles and histories, which is something that also needs to be taken into account in order to properly manage fish stocks. Impacts from mismanaged fisheries can be seen around the world, Philippe sets out to find out what is being done to protect this vital resource.

Philippe Cousteau travels to Plymouth, England, one of Europe’s largest seafood exporters, to explore fisheries and the impacts these practices can have on the environment. Philippe joins Dr. Martin Atrill from the University of Plymouth out at sea to use a trawl net for a fish survey and to understand how data is collected and fish populations are monitored. Fish require balanced and healthy ecosystems in order to thrive and feed our growing population. Philippe joins Dr. Abigail McQuatters-Gollop to learn more about plankton the base of the food web that supports all fish.

For anyone looking to teach and learn more about biodiversity. This resource includes 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.

Join us as we celebrate the launch of our 2018 EarthEcho Expedition: PlasticSeas with one of your young ocean protectors, Shalise. Shalise believes we need to protect our beautiful oceans for future generations as the oceans are essential to life on earth.

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.
