We often talk about an overcrowded planet in terms of humans - but what effect does this have on animals? KAITLYN GAYNOR is the author of a new report on how more wildlife is seeking an escape from the masses by adopting a nocturnal existence
The humble guppy fish may be tiny in size but it's big in brain power according to new research. Male guppies living within close proximity of predators have been found to have bigger brains than those who don't. SABRINA WEISS reports
The impact of human behaviour on the environment is well documented but now it seems man has become an evolutionary force in the lives of female Scandinavian brown bears as they change parenting tactics to ward off hunters. CATHERINE HARTE reports
Building on a talk prepared for the Resurgence 'One Earth, One Humanity, One Future' conference, (although not presented at that event) Fritjof Capra explains new scientific evidence supporting the long-held supposition of Buddhists and others that humans are interconnected and part of nature.
The origin of life has long been the deepest of mysteries, writes Chris Busby. But in fact, the spontaneous arising of life from molecules in Darwin's 'warm little pond' is the inevitable result of their selective energisation by quantized infra-red radiation. Now, some four billion years after life first developed, precisely the same processes continue to drive the operation of all living systems at a cellular level.
The world we inhabit is a miracle of billions of years of evolution as life has unfolded in its full beauty and diversity, writes Grant A. Mincy. But human activities - deforestation, mining, urbanisation, pollution, climate change - are tearing away at the functioning fabric of the living biosphere. A mass extinction is under way, and it must be halted, and reversed. But how?
Novel canids are hunting the forests of Eastern North America from Florida to Labrador, writes Roland Kays, where hybrids of coyote, dog and wolf have evolved into highly competitive forms. But is it the evolution of new species? If left in long term isolation, perhaps - but that's not about to happen. Genetic mixing and evolution still have a long way to run.
Ever since the 1970s we have lived with the growing awareness that our ecosystem is fragile and the perpetual exploitation of our natural resources impossible. By the late 1980s, even The Sun newspaper had its own green correspondent. Everything we buy, use and throw away has an impact somewhere on the ecological continuum, and nowadays the most bullish Western consumers’ consciences are regularly punctured by shards of eco-worry. We also increasingly realise that working ever harder for more possessions, more options, more stuff, doesn’t tend to make us more content.
