Planetary boundaries and doughnuts
In 2009, the Stockholm Resilience Center presented Johan Rocksröm’s model of planetary boundaries. It has 9 different indicators that measure almost all environmental problems. The only things that there are no are light pollution, noise, radiation and comfort and aesthetics. Planetary boundaries are: freshwater use, land use (including desertification, deforestation, etc.), biodiversity, climate change, fine…

The cruel reality of meat production – there is no such thing as a happy chicken or a climate-friendly pig
The biggest environmental act you can do is to become a vegetarian, preferably a Vegan. Did you know that more than 30% of global greenhouse gas emissions come from meat production? This is more than all the traffic in the world combined. A kilo of beef has up to 50 times more climate emissions than…

Methane ice clathrates and climate, the powder keg of the oceans
There are several feedbacks related to climate change that can either slow down or accelerate global warming. Climate change affects these and they, in turn, affect climate change. These include, for example, the earth’s albedo, i.e. the reflectivity of snow and ice in particular, which cools the earth by reflecting the sun’s radiation away. Warming…

Science, economy, consumption and environmental degredation
The development of natural science is the basis for new innovations and the development of technology. The development of technology is basis for economical growth, energy consumption and population growth. The biggest single factor in economical growth is the development of techonology. All of these, economical growth, energy cosumption, population growth and the development of…
