Or it could make the question of another form, the future of our planet in what the preservation of the environment says respect will be a dream or a nightmare? This reply it will be perfectly answered for our grandsons and greats-grandson in a next future. While I wait the reply to this question preoccupying, I can risk a palpite on the question. The planet walks the fast steps for the nightmare, the man caused and is causing serious ambient problems, that I do not know if we will obtain to only revert the picture with the use of future technologies, the ambient problems is so serious that many people laypeople on the subject, can until finding that this everything is ‘ ‘ papo’ ‘ of ambientalista, more it is not. to prove the evolution of the ambient problem I go to present only one of the tests that the proper lady nature presents in them. The ambient problems are old, are not a recent thing, but they behind have a marcante starting point, that was during the industrial revolution of 1930, accurately eighty years that the pollution and the deforestation had given broken the ecological catastrophe that we live deeply today. She thinks! If you know somebody that lived has eighty years, you ask to this person as it was the environment at this time, and it she goes to answer to it, that the waters of the clean rivers were we enxergvamos the fish, the bush she was green and satiated and it covered great part of our cities, air was pure and strap I smell of the field, the fauna and flora were abundant, and the alone so fertile age that we did not need to season it. eighty years later, we have alarming factors here as: climatic changes with extreme events, pollution of air, water and ground, full aterros of garbage without reaproveitamento, deforestation, disordered population and industrial growth between as much other problems. Which eighty years, a next future will be then the expectations for daqui if to analyze cold, if the man did not acquire knowledge and to invest heavy in the ambient education of the young, and in a severe fiscalization on the polluting sources, the year of 2090, can be one year that you would not like to live deeply.
