Ballast water release from ocean vessels has introduced hundreds of invasive species to coastal ecosystems worldwide, causing major disruptions to fisheries and biodiversity. Attempts to control aquatic invasions have met with mixed success in general. However, a new study suggests that a bi-national regulation targeting ships entering the Great Lakes since the mid-2000s has been remarkably effective in reducing a large proportion of the invasive species in the world鈥檚 largest freshwater ecosystem.

As the global community is called to re-examine our relationship to the natural world, one thing is certain: despite all our technological advances, humans are completely dependent on healthy and vibrant ecosystems for water, food, medicines, clothes, fuel, shelter, and energy, just to name a few. The 2021 theme, 鈥淲e鈥檙e part of the solution鈥�, was chosen to be a continuation of the momentum generated last year under the over-arching theme, 鈥淥ur solutions are in nature鈥�, which served as a reminder that biodiversity remains the answer to several sustainable development challenges.

A team of researchers from 鲍鱼直播 and the Quebec government have discovered microplastics (in the form of polyethylene 'microbeads,' less than 2 mm in diameter) widely distributed across the bottom of the St. Lawrence River, the first time such pollutants have been found in freshwater sediments.
