Mass Birds and Fish deaths, What does it meant to us

Well, that is a piece of 'non-news' if ever I saw one! My best guess would be the very severe and unseasonal weather which hit both the Eastern United States and Northern Europe at about the same time in late November last year. Many wildlife populations are much more sensitive to extreme and unseasonable weather conditions than we realise and a cold snap, a heatwave or a drought in the wrong place at the wrong time can wipe out huge numbers of a particular species. This does happen quite regularly (and always has), though not often in such remarkably large numbers and in such a concentration. Fortunately, populations do eventually recover. If, say, 90% of a population is wiped out one year, there are still 10% who survive and carry on to breed. Since there are far fewer, there is usually more of their natural food available and the next few generations will thrive and the population will recover.

Good Day! Maybe its because of the bad condition of the Earth now that made those birds and fishes die.
