Light pollution is often characterised as a soft issue in environmentalism. This perception needs to change. Light at night constitutes a massive assault on the ecology of the planet, including us. It also has indirect impacts because, while 20 per cent of electricity is used for lighting worldwide, at least 30 per cent of that […]
The world’s leaders (the vast majority of them anyway) have finally come to terms with the dire implications of global warming on the Earth’s climate. With every passing day, the polar ice caps shrink in size, rising sea levels subsume another low-lying island, and the incidence of adverse weather conditions continues to swell. The Paris […]
In a recent Nature Sustainability paper, a team of scientists concluded that the Earth can sustain, at most, only 7 billion people at subsistence levels of consumption (and this June saw us at 7.6 billion). Achieving ‘high life satisfaction’ for everyone, however, would transgress the Earth’s biophysical boundaries, leading to ecological collapse.
The damaging decline of our environment is undoubtedly a pressing concern. The rise in pollution, excess use of energy, and our reliance on non-recyclable materials are just the tip of the proverbial iceberg. Whilst positive changes are being made, including supermarkets cutting down the use of plastic bags and the EU’s ban on non-biodegradable products, […]
Despite today people are living longer, healthier, and happier lives than ever before, there are still many problems that humanity should address. One of the most important of them is water inequality. While people in First World countries can very easily take fresh, clean water for granted, more than 800 million others in impoverished areas […]
As a result of global warming, the seas warm and ice melts. Naturally, Earth’s oceans have risen steadily – or at least, it was thought so. According to a new study based on 25 years of NASA and European satellite data, rather than increasing steadily, global sea-level rise has been accelerating in recent decades. If this trend […]
Our civilization emits so much CO2 into the Earth’s atmosphere, that only planting trees is not enough, according to a new study. Limiting global warming to below 2°C above compared to preindustrial times requires not only massive near-term greenhouse gas emissions reductions but also the application of “negative emission” techniques that extract already emitted carbon […]
Alex Kuzoian and Jessica Orwig of Business Insider has prepared a video titled “Here’s why Elon Musk wants to colonize Mars”. In the video below, we see some reasons why we should colonize Mars someday.
According to a study titled “The Anthropocene is functionally and stratigraphically distinct from the Holocene” and published on Science Magazine, we, humans, changed the world so much that now we can say the world entered a completely a new geological era, “Anthropocene”.
