Recirculation of Plastics

Tiistai 20.11.2018 klo 15:32 - Mikko Nikinmaa

A huge problem has been generated for most Western countries. China has stopped importing any plastic waste. Exporting plastics for reuse in China has been the way most West European and North American countries have got rid of accumulated plastics. While much of the plastic waste has been reused in plastic toys and such like, some of it has ended up in the huge amount of plastics in the ocean near China. In principle the reuse in, e.g., plastic toys is a good way of getting rid of plastic waste, but one should be able to ascertain that all the waste is going for the intended purpose and not ending up in oceans. One thing is that plastic waste should be clean and uniform. Earlier on one did not care if plastics had toxic components, since they were thrown away anyway (one did not care that the toxicant ended up in the environment). However, recycling of plastics requires that the new products made are not toxic. Also, people sorting the plastics should not be exposed to the toxicants. The need for toxicants in plastics has actually disappeared making large-scale sorting feasible. It can be done more and more automatically - and should be done, if not in China then in the places of origin.

Growth - threat to Earth

Lauantai 10.11.2018 klo 11:17

Reading the news, two problems are invariably brought forward: population growth in Japan and Europe have completely stopped and economic growth is again slowing down.  These are given as negative news, although at the same time the news bring forward that this year the day that the resources of the world that could be used per year if sustainability were the aim was reached earlier than ever. Consequently, both news items about the stop of population growth and and decrease of economic growth are positive news for the Earth, hopefully more of them follow.

As a need for economic growth, it is invariably said that if economic growth does not continue, one cannot continue with the present benefits - but wait a minute, those if us who lived in 1970s lived quite happily then, even though all the economic indicators were much worse than today .- the gross national product was only a fraction of today's and there are many things all of us consume now, which were not needed then: and honestly, do we really need them.

As a need for population growth it is usually said that without it there is not enough working force to pay pensions to retired people (and jobless atc.). Again, wait a minute, at the moment immigration is the most negatively thought-about aspect of life in Europe. Wouldn't it be actually right to welcome immigrants and say that they are needed to make it possible to continue the welfare states of Europe. If this were the attitude, I bet the majority of immigrants would soon assimilate to society. And if immugration were mostly young people and children, taken in with a positive attitude, they wood soon see their new living place as home and try to make the normal habits there their own. The hostile apartheid mentality of the right wing populists generates hate and conflicts, which is good for nobody.

To combat the major environmental problems in the world, we would need to forget nation satates, and think that we are citizens of the world. This does not mean that we would need to forget our identity or that we should not try to convince other people about the points done well in our societies. But - I can say that I am a Finnish World citizen, against inequality, male white domination, environmental distruction etc. However, although my aims are good, I make mistakes - human as I am.

World Population Day

Tiistai 10.7.2018 klo 10:52 - Mikko Nikinmaa

In 1960's-1970's when the environmental movement started, population growth was considered to be maybe the biggest problem for the future of the earth - it was considered that world's agriculture could not feed population exceeding 5 000 000 000. We are now 8 000 000 000. So, the development of agricultural practises has enabled food production far beyond the expectations of late 20th century.

However, that does not mean that there would not be many problems associated with the large population. The increase in agricultural production has been achieved with the help of pronounced pesticide use and artificial (mineral) fertilization. Fertilization in crop production is an important component in eutrophication of waters, which is also caused by the excretion of people and livestock. Water and land is polluted by pesticides and other toxicants. Recently, as a result of waste production of the large human population, the huge plastics problem has been generated. One can also say that the climate change, associated with the large use of fossil fuels, is caused by the large population. 

Further, the oceans are overfished, the mineral resources are overexploited etc. In fact, the earth's resources are drastically overused - if the population were much smaller, the overuse were much easier to avoid.

The World Population Day is on July 11. As one aim of the future for world population is to curb population growth. In Europe the population is not increasing any more, and the same could and should be the goal for every other part of the world. The second aim should be to increase recycling: instead of producing new products of virgin materials and at the end of the product's life time throwing it away, everything should be recycled. It would be important for us in Europe to have all the household machines to be made so that they would be repaired instead of being thrown away/replaced when broken down. As a final aim, the whole concept of economy should be changed: economic growth should not be sought for.

As individuals and families/groups we can celebrate World Population Day by decreasing the group's use of resources per time. The manifest of concerned scientists can be found at, which generally is a site to follow if one is interested in anthropogenic influences on Earth.

Healthy environment is needed for functioning economy

Perjantai 9.3.2018 klo 16:42 - Mikko Nikinmaa

To be sustainable, any economic theory needs to take into account the limits set to economies by the global environment. Otherwise any economic actions are just very hard-repayed loan from future generations. As the two worst alternatives are either that a small proportion of mankind can leave this planet, when it becomes uninhabitable, to continue the wasteful way of living in another planet until that is also spoiled or that most people dye and a small proportion continues to live in the spoiled environment.

To avoid these worst-case scenarios, one should actually give the Nobel price in Economics in continuation to economic theories that strive to reconcile economics and environment, as suggested by Ripple at el. in “The Role of Scientists’ Warning in Shifting Policy from Growth to Conservation Economy”, which can in full be viewed at

"Most helpful for this paradigm shift, both symbolically and pragmatically, would be for the scientist members of the Royal Swedish Academy of Sciences to insist that its Economic Sciences Prize Committee give greater weight to awarding prizes for economic theory that accounts for environment–economy interlinkages and feedback loops. If Nobel memorial prizes in economics were given to those drawing attention to economic drivers of environmental degradation and the well-being implications of degraded ecosystems, it would draw attention to problems with mainstream economic theory as well as encourage other economists and natural scientists to collaborate and to do more work in this area."

Economy and environment are not opposite, but there cannot be a functioning economy without healthy environment in the long run.

Climate Bandits

Maanantai 3.4.2017 klo 13:18 - Mikko Nikinmaa

In these blogs I have earlier been critical of president Trump's actions. However, recent news indicate that he has a brother in Putin. Putin is also of the opinion that man is not responsible of climate change, and said that increased temperature is an opportunity, not a threat to the arctic environment.

It is a pity that the leaders of two major countries live so much in the past. Fifty years ago the situation was not as bad as now, but Putin and Trump cannot see to the future problems, they only see that doing things as in the past would be the way to go forward.

Trump's budget proposal and the environment - time to cry

Perjantai 17.3.2017 klo 10:14 - Mikko Nikinmaa

The White House indicated that not a cent would be spent to actions against climate change. It would just be a waste of voters' money. The anti-environment attitude was seen in the budget proposal also otherwise with more than 30 % cuts in the budget of Environmental Protection Agency. The planned cuts would make USA a backward country with regard to environment - the attitudes of leaders in China and even India are far more modern. If Trump budget cuts in environmental actions are carried out, and if the environmental attitudes of the White House become more widespread among American leaders, I pity the young people and children who must live with increasing pollution - the backward situation will not affect only USA but also rest of the world. In 1960's, which appears to be President Trump's "golden age", there was a lot of environment to pollute. Unfortunately, this is not the case any more - sustainable future requires that environment is included in every economic decision. Our children can ask that of us.
