Brutal deep-sea mining is destroying the entire marine ecosystems – STOP mining in the oceans
About 70% of the Earth’s surface is covered by oceans, and a large part of the world’s minerals are found on the seabed. Norway became the first country to allow commercial mining on the seabed in 2023. Deep sea mining is mining on the seabed, which has very destructive effects on marine ecosystems in many…

Biodiversity
22 nd May the international UN Biodiversity Day was celebrated. Biodiversity means the diversity of nature. It can be measured as genes, species or different biotopes and ecosystems. Creator or Nature, however you think of it, has created an incredibly diverse and colorful patchwork of ecosystems full of different species. The biosphere covers the entire…

Suomenlinna – an oasis of biodiversity in the center of Helsinki – how the ecological intermediate disturbance hypothesis can be seen in the nature of Suomenlinna fortress islands
Can man and nature live and flourish side by side? Can human activity greatly benefit nature? The intermediate disturbance hypothesis (IDH) assumes that species richness and diversity at the local scale are at their peak when disturbance is of intermediate intensity (Grime, 1973; Horn, 1975; Connell, 1978). This is how human activity often increases the…

Global village, a bit fly and diversity – systems and synergy
When two things interact with each other, a system is created. The system of two components is the simplest possible system, for example the Earth and the Moon form a system where they affect each other with their attraction. Compared to this, our entire Solar System is a very complex system with millions of components.…

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…

The Montreal Biodiversity Convention paints concrete goals – one third of the Earth’s surface to be protected
At the United Nations’ Biodiversity Conference in Montreal, they managed to agree on global goals for the protection of biodiversity. Montreal was a continuation of the meeting in Kunming, China, which I wrote about earlier. The agreement and its goals are a similar and equally significant institution as the Paris climate agreement, and its numerically…

Elysium – A Good Earth in the Year 2122
I present a thesis: the world’s problems are caused by relationships. Ecological problems, i.e. environmental problems, arise from the fact that man’s relationship with nature is broken, and social, i.e. societal problems, such as wars and poverty, from the fact that man’s relationship with other people is broken. In the Bible, the relationship between God…

The roots of capitalism and fair economics – in fair play everybody wins
Bhopal, India On December 3, 1984, Union Carbide’s insecticide factory, owned by the US giant Dow Chemicals, releases huge amounts of toxic methylisocyanate into the air and water bodies in a short period of time. 3,500 people die from terrible poisoning symptoms, tens of thousands are injured, and later another 50,000 locals die from diseases…

Climate change today and the path from extreme disaster to sustainable balance
It finally came to this because of humanity’s greed: A couple of friends in India said that there has been no monsoon for three years and half of the palm leaves have turned yellow and died. A friend in Italy says that local people don’t go out there at all because of the scorching heat.…

Systems thinking in environmental sciences – nothing is isolated in nature
Systems thinking is all about relationships, how the parts together affect the whole and trends, changes and problems. By analyzing these, we find solutions. People often want to simplify things, but in reality nature is very complex. Systems thinking is very important in environmental science. First of all, natural systems are very complex in their…

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…

The earth does not have a closed system – mines and factories always leak into the environment
In physics and thermodynamics, a closed system means a natural or human system that does not interact with its environment in such a way that it exchanges matter with its environment. In an isolated system, neither matter nor energy would be exchanged. The fact is that there is no isolated system except the entire space…

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…
