Very good companions! Today we come with the twelfth edition of Curiosidades. This time, of animals. To start.

We have seen them move, move, change their habitat en masse and adapt in their new, this behavior, what will it be? Here, the answer.

In many parts of the world when winter or dry season arrives, some animals migrate to other stations. The best known example is that of birds, which moves in large flocks to warmer areas. But most of the migratory animals do not do it to avoid the cold but because with the winter they are scarce and until much of the ones that it serves as food disappear, Example? Herbs, futas, flowers, grass or other small animals.

To conclude, something I want to emphasize, is, pollution. This affects us all, and if we do not start doing something, even the smallest account, we do nothing, and we continue throwing garbage in the streets, bags to the sea, throw everything we have and do not recycle, we will not reach no side, environmental pollution is a serious problem, which is left aside, thanks for reading!
