One can demonstrate for climate and environmental protection, occupy factories, ships or other things and do many other things. But to only draw the public’s attention to existing and future problems is unfortunately quite helpless. The public can only demand solutions, but cannot provide its own.
It will be the technologists and scientists who will save our world. No one else has the know-how and resources to apply it. That is why we should not blame or demonize the engineers and researchers, but only help them to research in the right direction.
It’s amazing what ideas technologists are pursuing to correct past mistakes. Or did you know that in various parts of the world there are teams working on the neutralization of nuclear waste to avoid burying this legacy? Did you know that they want to break down the harmful carbon dioxide emissions and process them into new materials?
The public should support these researchers and give them a free hand. This requires a little background knowledge, but never before has it been so easy to get information
SO2 (sulphur dioxide) and NO2 (nitrogen dioxide) are very harmful gases for nature and humans. They are emitted by diesel engines without any flue gas filtering. Especially the heavy oil burning marine diesel is harmful. After all, they emit many cubic metres of the gases per minute. Only the ban on heavy fuel oil can help here.
NO2 is harmful to humans and other living beings. You can tell just by the pungent smell and the scratching of the throat. SO2 develops sulphuric acid in contact with water. It is certainly not good to have constant contact with it. Both gases have a very damaging effect in continuous exposure and shorten life.
Shipping is responsible for about 13 % of all SO2 and 15 % of all NO2 emissions worldwide. There are ports where every breath makes you sick.
The “highways” of world shipping can be easily traced by their SO2 emissions. Under “www.windy.com” the routes are easy to find if the world map is adjusted accordingly. Wide brown-coloured paths that stretch across the oceans. It’s time to do something about it.
In a first step, liquid natural gas can be used to make a ship’s exhaust emissions much cleaner. In the second step, we can then switch to using only stored electricity or clean hydrogen. The technologies are developed and available. Only the purchase decisions of the ship operators are still missing.

The fire disasters in East Australia, in Brazil and even in other parts of the world are not only just triggered by a period of hot summer seasons – they are a direct result of the global warming. If one believe in the statements that the human civilization is not the originator of this situation or not something is happening. The result is that thousands of acres of woods, bushes etc. have been burned down. The forests may recover themselves, if they would have enough time. But the next fire season is coming and the sparsely growing green in the burned areas will be destroyed again.
We have no chance to protect the forests from lighting strikes or other natural causes for fires. But we can prevent that humans are the arsonists. No open fire, no cigarette or any other careless behavior. Also we can fight against criminals, who uses fires for their own business objectives or set fires just for fun.
Arial firefighting is an important part of the actions against wildfires. Just aircraft can react as fast as required and can transport a large amount of fire retardants into the flames. This does not mean, that any other way to fight fires is wrong – quite contrary to this the complete force is a team. Ground units block the fire, create firebreaks and extinguish any remains of the fires or prevent a reinflammation. The helicopters assist this by a selective precise water bombing and the fixed wing forces extinguish larger areas in short time. Even in rough terrains this mixture of forces is essential.
