A quiet mid-August Sunday, with the vineyards already at work and the sea asking for our attention. Five stories to read slowly.

A season arriving early

Heatwaves push Portugal's grape harvest weeks earlier

Intense heat has pushed forward the start of Portugal's grape harvest, traditionally beginning in September, industry representatives told Lusa. In the Alentejo and Tejo, picking started in late July, while the Douro saw a one-to-two-week advance. ViniPortugal's president Frederico Falcão linked the shift to rising temperatures accelerating grape ripening, requiring closer vineyard monitoring and faster decisions. CAP's Luís Mira said harvests have come earlier over the past 15 years without loss of quality. Producers also report growing labour shortages, while some, like Vicentino Wines, say this year's harvest is proceeding on schedule.

European flat oyster reefs have collapsed, study finds

A study published in Conservation Letters warns that reefs built by the European flat oyster, once spanning over 1.7 million hectares across Europe, have ecologically collapsed due to overfishing, pollution and disease. Surviving reefs now average fewer than one oyster per square metre and rarely exceed 0.1 hectares. These reefs once supported fish, crabs, starfish, seabirds and coastal communities, and helped protect shorelines from erosion. Researchers say current restoration projects in the UK and Ireland are unlikely to be enough, and call for greater funding and a historical perspective to guide recovery efforts.

One cigarette butt can contaminate 1,000 litres of water

Pharmaceutical company Aflofarm has warned that a single cigarette butt can contaminate up to 1,000 litres of water beyond safe limits for aquatic life, releasing nicotine and thousands of toxic chemicals. The company estimates 4.5 trillion butts are discarded worldwide each year, making their non-biodegradable plastic filters the second-largest source of plastic pollution globally, with heavy costs in water, trees and human lives. Children and pets are especially exposed, through residue on toys and surfaces or contact with contaminated sand. Aflofarm proposes five measures, including always collecting butts rather than leaving them on beaches, to promote a healthier summer.
