Hot Topics Calendar

Exploring current issues in the classroom

This feature was developed by Resources for Rethinking to connect students to some of the efforts being made to solve important problems that are affecting our planet. Hot Topics are published during the school year to coincide with the timing of national and international campaigns taking place to raise awareness of these key issues.

Each Hot Topic edition includes links to classroom materials from theResources for Rethinking database that will encourage students and teachers to explore the environmental, economic and social dimensions of these issues and to take action in support of the larger campaign.

Great Canadian Shoreline Clean Up TM
FALL 2015

Aquatic habitats deliver goods and services that are essential to all life forms on our planet. Unfortunately human impacts from industrial, commercial and recreational activities are directly or indirectly threatening the health and sustainability of these critical areas.

Taking part in a shoreline or riparian zone clean up can help students appreciate the importance of aquatic ecosystems while making a meaningful contribution to their communities. A shoreline clean-up can also be an enjoyable experience for students and great way to start off the school year!

Why Care About Aquatic Ecosystems and Shorelines?

  • All forms of wildlife require water, food and shelter from predators and the elements. Healthy shorelines provide all of these.
  • Shorelines offer an amazing variety of habitat types that support much of the planet’s biodiversity.
  • Healthy shorelines are requirements for healthy water quality.
  • Two-thirds of the world’s major cities are situated along coasts and millions of people vacation on shorelines each year.
  • Human disturbances are destroying coastal habitats and the ecological and economic services they provide.
  • Shoreline pollution also makes its way into pelagic zones killing aquatic life, threatening human health, causing toxic algae blooms and forcing beach closures.
  • Currents often carry pollutants far from their source of entry where species consume and absorb them.
  • It is estimated that up to 1.5 million tons of trash and debris forced into the ocean as a result of the 2011 tsunami in Japan will wash up on Canada’s Pacific shores.
