"Both noise and atmospheric pollution, mass tourism and the housing crisis it causes, and the emission of greenhouse gases from aviation, all point to the same solution. It is simple and gentle. It is necessary to reduce air traffic", say the organisations, which launch the appeal in the face of "the intention of the political and economic elites to increase the airport capacity of the capital".

In the appeal (open for subscription at https://aterra.info/lisboa-com-os-pes-na-terra/ ), the organisations consider that aviation is a danger both to the health of the population and to planetary health, and ask for solidarity with those who suffer from the impacts of air traffic and the expansion of airports, in Portugal and in the rest of the world.

“The ecological crisis is an opportunity for us to radically change for the better”, say the organisations, considering that this involves “reducing the total installed capacity at Lisbon, Porto, Faro and Beja airports”, and promoting the railway.

The organizations emphasise that the airport is the biggest source of pollution in Lisbon and a threat to the health and well-being of the population, with planes flying over Lisbon and Loures every two and a half minutes.

In addition to reducing planes, the organisations advocate in the document that the railway be developed as a means of transport for medium and long-distance trips, connecting Portugal, day and night, with Spain and the rest of Europe, and also making connections across the country.

The organisations ATERRA, Campo Aberto, Climáximo, GAIA, Left Hand Rotation, Morar em Lisboa, Rede para o Decrescimento and Stop Despejos have all signed the appeal.
