At the start of the 7th century BC, it was a mighty military machine and the largest empire the Old World had yet seen. But then, before the century was out, it had collapsed. Why?

According to the society, which is the veterinary division of the charity International Cat Care, culling to control cat populations is also rarely effective or acceptable, whereas trap–neuter–return programmes and rehoming (in appropriate cases) can offer effective and humane solutions, but need to be properly managed and targeted. https://phys.org/news/2013-09-isfm-welfare-unowned-cats.html Plants & Animals Fri, 06 Sep 2013 11:15:53 EDT news297684945 It's a weird, lopsided fight if ever there was one: seagulls divebombing to attack and feed on the fat of 50-ton whales and their babies.

And although the outcomes of these crises have varied from total eradication (the Classic Maya) to depression and eventual recovery (China), each collapse has been regional in scale. Now, a variety of problems have combined to move the global civilization toward a collapse. https://phys.org/news/2013-01-equal-rights-women-key-civilization.html Social Sciences Mon, 14 Jan 2013 07:30:01 EST news277369975 Throughout our history environmental problems have contributed to collapses of civilizations. A new paper published yesterday in Proceedings of the Royal Society B addresses the likelihood that we are facing a global collapse now. The paper concludes that global society can avoid this and recommends that social and natural scientists collaborate on research to develop ways to stimulate a significant increase in popular support for decisive and immediate action on our predicament. https://phys.org/news/2013-01-collapse-global-civilization.html Environment Fri, 11 Jan 2013 06:31:16 EST news277108262
