Nature enhances human health, but environmental degradation now negatively impacts well-being, necessitating education reform for Planetary Health.
Architecture can no longer be conceived as an isolated object, detached from the technical networks that sustain contemporary life. This condition calls for new readings and approaches.
We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
Every city contains two transportation systems. One is the visible network of roads, rail lines, sidewalks, and bus routes mapped in planning documents. The other is the invisible geography of privilege and exclusion embedded within it: the neighborhoods that received highways instead of parks, the communities whose bus routes were cut, the sidewalks that abruptly end at the edge of a district.
Across history, the relocation of capital cities has often been associated with moments of political rupture, regime change, or symbolic nation-building. From Brasília to Islamabad, new capitals were frequently conceived as instruments of centralized power, territorial control, or ideological projection. In recent decades, however, a different set of drivers has begun to shape these decisions. Rather than security or representation alone, contemporary capital relocations are increasingly tied to structural pressures such as demographic concentration, infrastructural saturation, environmental risk, and long-term resource management.
While the data shows 80% of people live within walking distance of green or blue spaces such as a river, park or woodland, it also reveals a disparity between rural and poorer urban areas. In some areas of local authorities, fewer than 20% of residents live close to these spaces, according to data released by the Department for Environment, Food and Rural Affairs on Wednesday.
St. Michael's College at the University of Toronto will host Mappa Mundi: Mapping the Mediaeval World, an in-person symposium exploring medieval cartography and how people in the Middle Ages visualized and interpreted their world. The event will take place Saturday, April 11, 2026. Hosted by Jacqueline Murray, the symposium examines mapping from two key angles: how medieval societies conceptualized the globe - including spherical representations of Europe, Asia and Africa, as well as mysterious regions beyond the known world -
When routes are well organized, there are clear directional signs, and speed limits become reasonable. The early installation of warning signs allows transport companies to plan deliveries more accurately and avoid delays. For businesses, time is money. When a truck carrying goods does not spend hours detouring due to an unclear traffic scheme or stuck in traffic where it could have been avoided thanks to competent traffic management, fuel costs, driver wages, and vehicle maintenance costs are reduced.
Cities around the world share a common goal: to become healthier and greener, supported by civic infrastructure that restores ecosystems and strengthens public life. The question is how to reach this. Global climate targets, local building codes, and municipal standards increasingly guide designers and planners toward better choices. Still, many cities struggle to translate these frameworks into everyday, street-level comfort and long-term ecological protection.
That local exodus is documented by Cornell-led research that mapped annual moves between U.S. neighborhoods from 2010 to 2019 in detail 4,600 times greater than standard public data. Called MIGRATE, the new, publicly available dataset revealed that most of those displaced remained within the affected county - moves not captured in county-level public migration data aggregated every five years.
Biodiversity loss is continuing at an unprecedented rate, with species becoming extinct at between 100 and 1,000 times the average pre-human, or 'background', rate. Human activities are the main cause. Although there are hundreds of local, regional and international initiatives to conserve and sustainably use species and ecosystems, many conservation scientists worry that measures such as interventions to conserve individual species or incentives to create protected areas are not supported by strong evidence from research.
His message is clear: our world is built on abundant energy, around 80% of which has come from fossil fuels over the past 50 years. Because supplies are limited, energy consumption will peak in decades - sooner if humans attempt to limit climate change. To keep global warming below 1.5 °C by 2100, the use of fossil fuels must fall by 5-8% each year - a pace that is too fast for low-carbon energy to keep up with.
