Good or bad news?

Good news for the natural environment, but very bad news for the birds. Any town it is beginning to close the rubbish dumps.
This means an improvement, the rubbish will be controlled.
As always, the activities of the man bring about imbalances.
A very important number of species of birds takes to long time having the rubbish dumps like an important feeding area.

Went the rubbish dumps are closed, how they are going to replace this food?.
For some species, like the Griffon Vulture, it will mean another new problem.
After the Bovine Spongiform Encephalopathy (BSE), commonly known as Mad-Cow Disease (MCD), the vultures and other species do not find carrion in the field, the government haven`t open new vulture feeders, and now the rubbish dumps are closed.
But other many species use the rubbish dumps of massive form, Black and Red Kite, Gulls, Crows, Storks ......
All of them will have problems by the closing of the rubbish dumps.

Barn Swallow decrease.

One of more sad events in natural environment is to be present at as some species go gradually falling, until becoming difficult to see or even disappear.
Often these processes seem to us more related to distant countries or rare birds.
This far from the reality.
To ours around a so common and familiar species as the Barn Swallow is disappearing quickly
The repair of the old houses in the villages makes to the Swallows finding difficult to breeding places.
The changes and uses in the agricultural systems cause that the means become more unhealthy for the insectivorous species.
