How have humans threatened our natural world more than ever before? Come and listen to some of the stories that our Earth tells when it is disturbed! They will surely get us thinking about how to better manage the impacts of our developments.
Towards finding Earth’s heartbeat and keeping a finger on the pulse
Alex Arkilanian (M.Sc. candidate at McGill University)
Humans are impacting the natural world more than ever before. A fact that has earned this epoch the name of Anthropocene. Scientists have proposed critical planetary boundaries and warning signals to monitor our Earth system and ensure we don’t push our planet past the brink. However, there remains a lot of debate around these new tools and their reliability. My work shows these concerns might have merit when these tools are used to predict crashes in animal populations.
Canada’s vast soil carbon and land-use change: a global stewartship responsibility
Nigel Roulet (James McGill Professor of Biogeoscience, Department of Geography. McGill University)
Canada contained 10 to 15% of the world’s terrestrial carbon: a large portion in northern soils. Very little of this carbon has been altered to date, but land-use change due to northern development threatens to convert some of it to atmospheric CO2 . The potential source of CO2 is large enough to offset gains from reduction in greenhouse emissions in other sectors. We have a global obligation to manage development so the vast majority of this carbon stays in the ground.
