How Australia is tackling river pollution

The Butterfly Effect ”-“ the sensitive dependence on the initial conditions under which a small change in a parameter in a nonlinear system can lead to large differences in later states. The name of the effect, given by Edward Lorenz, comes from a metaphorical example of how the fluttering of a butterfly’s wings can lead to drastic changes in the development and trajectory of a distant tornado. “

Lorenz’s discovery is considered the most authoritative evidence that the world is completely unpredictable and unpredictable in its laws and their consequences and does not always obey specific and predetermined laws. This metaphor lives its life from the moment it was invented and to this day it is good to remember it in various aspects, in which we talk about causes and effects. Why? Because we too were envious of a small tornado caused by daily actions, which have catastrophic consequences.

The “butterfly effect” is an applicable metaphor for almost anything we take as action or inaction. An important reminder that the sentence “ what is up to me, what I can do ” is more likely to be the wrong direction we are taking and this applies to everything – from the shortest dialogue we can to take someone to the butt we throw out on the street after it’s over.

I don’t feel like an eco activist, I’m not green, and sometimes I don’t pay attention to how I flutter my wings. However, I am making the necessary effort and in fact I am doing it even before topics of global warming, natural disasters and how we have a wonderful 14 degrees in December come to my mind. I will not discuss in depth how much we are to blame for the time we live in, nor will I wave a finger reproachfully, because I have chosen to believe that I too must have contributed to the creation of the problem, so I wave a finger only at myself. I am equally convinced that it is up to me to resolve it. At least as long as I step on this earth and use everything it has given me.

For better, for worse, we can now read and see everywhere how various techniques are applied that limit the pollutants and garbage we generate in our daily lives. As we do not all feel equally convinced in different parts of the world that it is right to change according to circumstances, urgent measures are still needed to prevent air and water pollution. Plastic and garbage, as one of the biggest problems we face today, are everywhere and managing them is a complex and difficult problem to solve. Little by little, however, there are those simple solutions that, although seemingly small, achieve great results.

One such example comes from Australia, which has been battling the terrible pollution of its rivers for years. In the summer of 2018, the country introduced a new filtration system, and the results were staggering. The system consists of nets that are placed at the outlets of the drainage pipes and thus help to capture large and large waste that has hitherto fallen into the water, which in turn supplies residential areas with water. The system was tested by installing two nets that managed to collect 360 kg of plastic and waste floating in the rivers in a few weeks.

Although the system requires maintenance, it is currently still operating successfully and is preferred by the authorities as it saves on human labor costs.

Both the authorities and the people are convinced that efficiency is a priority, and in this case the system works great and is a great example of how creative thinking is able to come up with great ideas.

Of course, hundreds of nets would not be able to catch the tons of garbage we produce if we did not start preventing them from reaching the water at all. But, this is a good start. Someone on the other side of the world is flapping its wings. I hope we follow him.
