Coral reefs, though covering less than 1% of the ocean floor, host a quarter of all marine life. Bleaching occurs when corals, under stress from high temperatures, expel the symbiotic algae that provide them with food and color, leaving them vulnerable to death. Scientists warn that the frequency and intensity of these phenomena make ecosystem recovery nearly impossible without a drastic reduction in greenhouse gas emissions.

This ecological crisis has a direct impact not only on marine biodiversity but also on the economies and security of millions of people who rely on reefs for food and protection from storms. The need for global mobilization is urgent, as the rate of tropical sea warming surpasses all previous prediction models.

The connection to cinema is direct — the EcoFrames Festival film “Tomorrow Begins Here” captures this reality in a striking way. The documentary transports us to a remote Pacific atoll, where residents experience the daily consequences of climate change. Through the film, we see how rising sea levels and the alteration of the marine ecosystem threaten to wipe out an entire way of life based on harmony with nature.

The film serves as a powerful reminder that behind the numbers and percentages of coral bleaching are people, traditions, and an entire planet at risk. The EcoFrames Festival aims, through such screenings, to transform scientific information into an experience, encouraging dialogue and action.

Cinema has the power to make us see what often remains invisible beneath the ocean's surface. The case of coral reefs is a cry of anguish from nature that we can no longer ignore. Through art and information, we can claim a future where "tomorrow" is not a whisper of threat, but a promise of life.

Additional Context

The 2014–2017 global marine heatwave resulted in over 50% of the world's coral reefs experiencing significant bleaching. During this period, 15% of coral reefs worldwide also suffered significant mortality. Some estimates suggest that 80% of reefs showed moderate or greater bleaching. This event is considered the worst coral bleaching event ever recorded.

The global decline of coral reefs impacts various services they provide, including tourism and food supply. Beyond heatwaves, climate change contributes to more frequent and severe storms, which can also destroy coral reefs. Ocean acidification is another factor, affecting corals by decreasing calcification rates and increasing dissolution rates. However, corals may adapt their calcifying fluids to changes in seawater pH and carbonate levels to mitigate some impacts of ocean acidification. The scientific consensus indicates that most coral reefs would perish if global warming reaches 1.5 degrees Celsius above pre-industrial levels, a target set by the 2015 Paris climate accord.
