Confap President Jorge Ascension stressed that "climate issues should be among the concerns of all, not just young people."

Speaking to Lusa, Jorge Ascensão recalled that the students realized that the speeches of the policy makers “were often far from the acts” in a subject that questions the future of the planet and the survival of the species.

“The desperation and tiredness of seeing little action” led young people to join the protest that was born last year following the movement started by the young Swedish activist Greta Thunberg.

Jorge Ascensão stressed that it is “important not to let into oblivion” the environmental problems that present society faces and welcomed the action of the young.

"I'm glad the young people don't give up," he told Lusa, noting that "the weather is following a catastrophic path."

Millions of people have been taking to the streets around the world to protest against the inaction of politicians on environmental issues and to demand measures in defence of the planet against climate change.

Protests in Portugal are being announced in about 30 locations where young people have said they would join the Global Climate Strike.

The youth appeal for a general strike, involving all sectors of society, was accepted by three trade union organizations, which delivered strike warnings: the National Teachers Federation (Fenprof), the All Teachers Union (STOP) and the Health, Solidarity and Social Security Workers Union (STSSSS).

Other union structures have not issued strike warning, but have contacted young people to express support and are spreading the manifesto for the protest, sources told the organization.
