Protecting our planet and our environment
Monitoring signs of climate change
From space, astronauts have witnessed the world changing firsthand, such as the significant shrinking of the Aral Sea and the sharp decline in the Arctic sea ice extent. Satellites provide crucial data about how our planet is changing. This information is invaluable to advance cutting-edge science, make climate projections and develop innovative solutions and services to mitigate or better adapt to the impacts of climate change.
Measuring pollution
Satellites are also helping specialists monitor and study air, water and soil pollution. For example, the thinning of the ozone layer was discovered with the help of satellites, and governments from around the world took action by signing the Montreal Protocol to protect the ozone layer and tackle climate change. Satellites can also locate oil spills and areas that have been contaminated by mining activities; as a result, the damage can be quickly contained and mitigated.
Protecting wild animals and their habitats
Earth's ecosystems are undergoing changes that affect humans and animals alike. Using satellites, we can monitor changes and promote the preservation of land and natural resources to protect our ecosystems and all forms of life on Earth.
Satellites are also useful for understanding and protecting Canada's biodiversity. They provide important data on wildlife and habitats, and GPS devices are used to track different species.
