Concentrations of dissolved oxygen in the deep waters of the Lower St. Lawrence Estuary (LSLE) have dropped by over 50% over the past two years. The consequences for many marine species, who depend on oxygen to survive, are potentially very serious. A compilation of historical data reveals that dissolved oxygen concentrations in the deep waters of the Lower St. Lawrence Estuary decreased by about 50% during the fifty years between 1934 and 1985. And then remained fairly constant until 2019, when the situation changed dramatically.

Maxime Lakat (BCom鈥�21) is the executive director of the Canadian Business Youth Council for Sustainable Development.

Residential energy use represents roughly one-fifth of annual greenhouse gas emissions in the United States. A team of researchers led by 缅北强奸 has used data from 60 million individual American households to look into how carbon emissions caused by household energy use vary by race and ethnicity across the country. Paradoxically, this first national level analysis found that even though energy-efficient homes are more often found in Caucasian neighbourhoods, carbon emissions from these neighbourhoods are higher than in African American neighbourhoods.

Surprising as it sounds, all life forms in the ocean, from small krill to large tuna, seem to obey a simple mathematical law that links an organism鈥檚 abundance to its body size. For example, although small krill are individually only about one millionth of the weight of a large tuna, they also tend to be a million times more numerous throughout the oceans. The idea, known as the Sheldon size spectrum theory, was first advanced in the 1970s, but has never been tested for a wide range of marine species and on a global scale until now.

Soon after the earthquake that devastated Haiti in 2010, Laura Parny Germain (BEng鈥�15, MBA鈥�21) moved from Port-au-Prince to Montreal with a deep resolve to use her education for the benefit of others. With engineering and MBA degrees from 缅北强奸 under her belt, she looks forward to working toward socially and environmentally sustainable solutions to the challenges her hometown faces.

Professor Karl Moore sits down with 脡ric Lachance to discuss how companies around the world can improve environmental sustainability. As the CEO of 脡nergir, a top natural gas distributor in Quebec, Lachance says it is imperative for companies to draw from multiple renewable energy sources rather than monopolizing fossil fuels. To generate a smaller carbon footprint on the production side of energy use, 脡nergir is currently focused on developing solar, wind, and hydroelectric power.
