Do you know that millions, hundreds of millions, more than a billion human beings do not have food to eat when they are hungry? Yes, of course, everyone knows it... So why is it that nothing changes; thousands of children continue to die of hunger every day?
CyberDodo and city maintenance (1-41)
The statistics have revealed that more than half of the global human population is currently living in cities. Concretely, this constantly growing concentration is going to produce more and more waste, as it is difficult to collect and treat it while respecting the planet, its inhabitants and future generations.
How did we get here?
For millennia, man and his activities have not had an impact on the environment. Our ancestors were not numerous enough and their rustic way of life was in perfect harmony with Nature. In modern terms, we could say that their carbon footprint was neutral.
Then gradually, with the evolution of the human species, their influence was extended. The more man improved his techniques (Gathering, hunting, fishing, cattle-raising, culture, etc.) the greater his impact on his environment.
However, for generations our ancestors practised recycling; they refused to let go of anything, everything was recycled and reused, everything had value and had to last as long as possible.
It is difficult to precisely determine when man's presence on Earth no longer became ‘neutral' for other living species and the planet itself, undoubtedly this was some time between the 19th century and the 20th century...
Back to the 21st century, where our lifestyle has a destructive impact on our beautiful planet, which is in fact our only home. The purpose of this case file is to make you aware of the challenge posed by the mountains of waste daily produced by billions of city dwellers.
What are we talking about?
In order to better understand what we are talking about, let's look at some figures. Generally a family of 4 people living in a rich country produces 1 to 2 tonnes of waste every year (CyberDodo decided to use the terms ‘rich' and ‘poor' in his case files in order to highlight the unacceptable gap existing between those who have too much and those who have too little).
Out of this massive figure, paper consists of one quarter, organic waste consists of another quarter, plastic consists of 15%, the same proportion for glass, and the rest consisting of various types of waste, of which some are particularly dangerous, such as batteries and other residue.
What to do with this waste?
For years, it was simply stockpiled in waste dumps in the open air or buried, if not thrown into the sea. Over the course of the years, certain waste took on gigantic proportions and caused serious pollution of water tables (See the case file focusing on this subject) following rainwater runoff, which transported noxious substances.
In numerous countries, this type of littering is always taking place and poses a danger for the present as well as future generations. But population growth and the resultant volume of litter constrained the authorities to find a solution to get rid of it, how to do this?
Since the end of the 19th century, incinerators have been designed and put in place so as to be able to burn most of it, is this a good solution? Without denying the indispensable progress that has been accomplished through this route, it is not ‘the' solution. Do not forget that:
1) There is no incinerator that fully does its job and even the most technologically advanced rejects toxic substances.
2) Thousands of incinerators in use throughout the world are extremely dangerous for the population and the environment.
3) A single incinerator is an important contributor to climatic reheating.
