No-one can be certain what the future might bring. But we all consider some outcomes more, others less likely. So, here are my personal scenarios and probability estimates for the near future of humanity over the next 100 years (please do comment and criticize…): Scenarios: Business-as-usual: We successfully continue with our present strategies, including fossil-fuel… Read More My Expectations for the Future
I dislike overpriced luxury goods. Like a 37 500 US$ pen, which is functionally equivalent to a 10 US$ pen, which is not much better than a 0.5 US$ pen. Now, buying this is stupid if you are a UAW union official using misused funds. But, more generally, it reminds me of our unjust, inequitable distribution… Read More The Ecological Footprint of Luxury goods and Bitcoins
One thing that worries me is that so many people are primarily nostalgic. They resist change and want to stay as close as possible to the past. I understand, of course, how we all are afraid of changes and an uncertain future. But consider the following: Imagine you are shipwrecked with your family on a… Read More Nostalgia, Denial, and Children
Our current nature conservation concepts aim to protect, on a scale of a few hundred years, what has been created by evolutionary forces in millions of years. What would change, when we consider evolutionary time scales? We know that we might be causing the sixth major geological extinction event. But we also know that five… Read More Why Should We Protect Biodiversity?
For most of our history, humankind viewed “nature” as something eternal and imperturbable. A god itself, a distant “mother” nature, or a creation of – occasionally angry – gods. In any case, nature was something to be discovered, conquered, brought to human use. Overcoming the adversity of nature was the essence of progress. Slowly and… Read More Protecting Nature in the Anthropocene
We know that our societies, with their unsustainable human population growth, pollution, and consumption of natural resources, are bound to hit the walls of our planetary boundaries. We know for decades that business-as-usual is not an option. We did achieve some success with the Millennium Development Goals and hopefully continue to do so with the… Read More War may give us hope
We know that we have to quickly and drastically reduce the emissions of greenhouse gases into the atmosphere if we want our children to lead a quality life. With quick I mean quick, i.e. within a few years, and with drastically I mean drastically, i.e. down to just 5-10% of present values. Still, on the… Read More Retrofitting fossil-fuel-based water and space heating with heat-pump systems – a climate change priority or just not feasible?
According to a recent Swedish review by Mia Romare & Lisbeth Dahllöf (2017), the production of 1 kWh capacity of lithium ion battery causes emissions between 150 and 200 kg CO2eq/kWh (CO2-equivalent per kWh battery capacity). Calculating with 175 kg, just the batteries of a 100 kWh capacity Tesla Model S account for 17.5 t CO2eq. The footprint of batteries increases… Read More The carbon footprint of electric car batteries
In 1976 Francois Truffaut explored the topic of children’s rights and child abuse in his movie: Small Change / Pocket Money. To quote: “Of all mankind’s injustices, injustice to children is the most despicable! Live isn’t always fair, but we can fight for justice. It’s the only way. It’s a slow process, but we do… Read More Children’s rights and intergenerational justice
Blogging is out of fashion. But I need some method to organize my learning process. If you find my thoughts and arguments useful, please tell me. And, if you can, help me with corrections or new insights. I am grateful for this, thank you in advance! –Gregor Hagedorn… Read More Wozukunft – What Will We Do With Our Future?
