O que resta no fim de um dia de férias
A imagem de um fim de tarde numa qualquer praia da nossa costa. É triste observar a quantidade de resíduos que ficam na areia: beatas, plásticos, papeis, restos de fruta,…
Será que no dia seguinte não vamos voltar ao mesmo lugar?
Que alertas terão de ser dados para se alterarem estes hábitos?

Marsh of Corroios: an environment rich either in bio diversity or in trash and scrap
Observatory of Birds in marsh of Corroios: a unique structure in Setúbal, Portugal, decisive to the conservation of nature, requiring attention.
The marsh of Corroios is the best preserved wet area all over the estuary of Tagus, south of Alcochete, Portugal, with a high biodiversity. The existing Observatory of Birds is an important structure giving support to the observation of nature, but it should receive more attention.
The marsh of Corroios plays a vital role in the populations of fish, bivalves, crustaceans and resident and migratory birds in the estuary of Tagus. Most of these birds come from the North of Europe; in winter, 5 to 10 thousand birds can stay in this area.
The vegetation presents a high biological productivity and the capacity of cleaning water from pollution.

Illegal gathering of mussels in river Tagus
Illegal gathering of mussels in Ponta dos Corvos, Seixal, estuary of Tagus, Portugal. A rentable activity but dangerous for the public health.
During May, we could see dozens of people in the river Tagus gathering bivalves to be sold to businessmen. An extra family income but a serious problem of public health, due to the presence of dangerous levels of toxins or microbiological contamination.
According to the Institute of the Sea and the Atmosphere, the gathering of bivalves is forbidden in the estuary of Tagus, since 3rd May. By the end of the month, at the low tide, dozens of people continue entering the river, as we can see in the photo taken in Ponta dos Corvos, Seixal. This prohibition is due to the “the presence of levels of toxins or microbiological contamination over regular levels”.
There are many businessmen who buy these bivalves at a low price and introduce them in the market, which may cause problems of public health.
Góis: vila de gente acolhedora
Góis, um município com pouco mais de 4000 habitantes, tem cada vez menos jovens: mas que vai equilibrando esta saída de população com a chegada de novos rostos e nacionalidades.
