9. Similarly, the populations of land animals have also fallen 39 percent overall.
10. More specifically, tigers are quickly disappearing from much of their range, for example, but their numbers have risen 63 percent since 2009 within several protected areas in Nepal.
Its time humans changed their ways in order to ensure a safe, healthy life cycle, continuity and harmony with the Earth and its precious inhabitants.
