Technology had enabled humans to explore the deep sea, the Earth's poles, and outer space. But we shouldn't forget historical lessons about frontiers in the process of traversing them.
Yes, humans hold awesome power over the rest of the planet, but nature will always fight our attempts to 'tame' the natural world.
The rise of urban greening is an opportunity to recast the relationship between people and environment. Humans and non-human species are ecologically intertwined as inhabitants of cities.
Our institutions are not solving the world's wicked problems, such as the refugee crisis and climate change. Can sustainable coffee – a bottoms-up, modular approach – provide clues to a better way?
An instant likely feels different to a person, or a redwood, or a gnat. What's infinitely small for one might be a whole lifetime for another – and that scale influences the choices we make.
A volcanic eruption in 1815 triggered a year without a summer – prompting a flowering of nature writing that is all too relevant today.
A philosopher of 'procreation ethics' at the center of a controversy over having kids explains why we can't ignore the population question in an era of climate change.
How long the Anthropocene will last, and what will be its most enduring attributes, will not be driven and decided scientifically.
An expert panel has announced that we truly are living in the geological era defined by humanity's fingerprint. But is it as simple as that, and does it leave "Anthropocene science" open to attack?
Liberty is a political matter bound up with institutionalised struggles for equality among individuals, groups, networks and organisations. This is where the cult of the free individual falls down.
A scientist dips her toe into a new form of group-based performance art: devising new words to describe new feelings and phenomena of a rapidly changing world.
Human activity doesn't just reduce biodiversity – new research explores how we are continually creating new species and ecosystems, too.
Science explains how people are changing our natural systems, but we need to recognize the importance – and power – of emotions and the spiritual world in charting a course to the future.
Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Fire has played a vital role in human history, and will continue to. Recent advances in fusion herald the freeing of fire from captivity back into its natural form.
The presidential candidates should be talking about exploring and cataloguing our biosphere, which holds vital clues for how humanity should navigate the future.
There's no need for manufactured debates about a new geological era – we should just get on with the business of solving our problems.
We're in a new geological era, say scientists.
Human activities have altered whole ecosystems with declines in species diversity, extinctions and the introduction of weeds and pests. But it's not just the outside world we're harming.
Global warming is, by definition, experienced worldwide. But a new study shows that the tropics were the first places on earth where the human effect on climate outstripped normal climate variations.
