Sessions aim to educate families on how small daily acts contribute to nature preservation.

Earth Hour is a global one-hour lights-off initiative organized by WWF to raise awareness about nature loss and climate change, with landmarks like the Empire State Building and Brandenburg Gate taking part across more than 190 countries.

Participation is free and open to all residents, with no pre-registration required.

A call to action encourages individuals and communities to engage in ecological gardens, food rescue, and regional nature conservation groups to support ecosystems.

Safety for the activity will be provided by the Calheta PSP to ensure suitable conditions.

WWF Portugal, led by director Ângela Morgado, notes participation from municipalities and public entities nationwide, plus educational sessions showing how everyday actions connect to nature conservation.

The coverage adopts an urgent, persuasive tone, urging systemic changes and personal commitment to protecting the environment.

Educational sessions for families will connect daily actions to positive nature impacts, emphasizing that protecting the planet often starts at home.

These family sessions also highlight biodiversity-friendly spaces and restoration challenges and solutions.

Ecological impacts discussed include warming effects on cold-adapted species, disrupted plant photosynthesis, and altered migratory patterns that reduce wildlife food resources.

The hour-long action marks WWF’s 20th annual Earth Hour, a movement that has grown from a Sydney campaign to a worldwide event reaching about 90% of the global population.

There is critique of political resistance to science-based policies and reliance on outdated energy strategies, warning against returning to nuclear, fracking, or weakened nature protections.
