Orcas: keeping your distance is the best thing to do when encountering them

oglobo10 September 2026 at 07:30

Keeping your distance is the best attitude when encountering orcas in the sea, regardless of whether they are playing or not. These creatures, due to their size and intelligence, are considered the queens of the seas, occupying the top of the food chain and being predators against which even the great sharks are no match. When orcas appear, sharks move away.

Although orcas do not see humans as prey, they remain wild animals and can be dangerous if someone insists on contact. In the sea, they have no natural predator, with humans being their only enemy.

Orcas can reach an average of eight meters in length and their teeth can grow up to ten centimeters. They inhabit all the oceans of the world and are extremely social creatures, forming tight-knit groups led by females and communicating in a complex way.

FT says Ricardo Reis was not appointed chief economist for criticizing Trump

According to the Financial Times, citing three anonymous sources, the International Monetary Fund (IMF) was preparing to appoint Portuguese economist Ricardo Reis, a professor at the London School of Economics, to the position of chief economist at the beginning of summer, but backed down after learning of statements in which he criticized the negative effects of trade tariffs imposed by Donald Trump. The IMF ended up appointing Silvana Tenreyro, also from the LSE, who took office in August and who, although sharing the same opinion on the tariffs, was considered "less critical" than Reis. An IMF spokesperson declined to comment on the process, citing the practice of non-disclosure about candidates. Expresso, citing the FT, notes that although Director-General Kristalina Georgieva is formally responsible for appointments, the United States exercises strong informal influence as the largest shareholder of the institution.

Some things half-done and many more yet to be done

This opinion article by Luisa Schmidt takes stock of the last 25 years of sustainability in Portugal, identifying both significant advances — such as selective waste collection systems, the growth of renewable energy, universal access to drinking water and progress in environmental education — and persistent problems related to land-use disorder, coastal erosion, forest management and dependence on road transport. The author argues that the next 25 years should be based on the decentralisation of renewable energy, the circular economy, the enhancement of the blue economy, the integration of environmental and economic values, investment in rail mobility and the strengthening of participatory local dynamics, also suggesting that Portugal can position itself as a promoter of sustainability policies in Europe and with CPLP countries.
