Um passeio pela praia fluvial de Merelim e ciclovia do Cávado
No parque de merendas encontramos logo à chegada, um apelo para que não se abandone lixo. No entanto verifica-se que em todo o espaço e na praia, só existem dois caixotes de lixo indiferenciado e não há pequenos ecopontos para a separação de resíduos. Há apenas, no estacionamento, um grande ecoponto. Reparei que havia lixo espalhado em cima das mesas e no chão.

Black and white world: a photo story about air quality
The air pollution was always a case of study and a fact of concern, as it is very dangerous to our health. Air pollution from traffic and industrial sources is highlighted as contributing to most respiratory diseases and the prevention of those should start before birth and, because of that, air quality is a major factor to our quality of life.

Light pollution in the city
By definition, light pollution, also known as luminous pollution or photopollution, is an excessive, misdirected or invasive use of artificial outdoor lighting. It is a side effect of our industrial civilization and it has been present in cities worldwide for the last 50 years. There are organisations that track the light pollution problem and provide accurate information about the levels of this sort of pollution in cities around the world, using modern technology and satellite mapping to keep us informed and aware of this phenomenon.

Cities are warming up, trees can be a solution
The annual report of the Copernicus 2020 programme concluded that the last decade was the warmest in Europe’s history, leaving no doubt about the challenges ahead for the old continent. The cities where most people live are likely to suffer the most from the global rise in temperature. Trees in cities could be one of the measures to adapt to the changes in climate.
