This article, like the others we will be publishing this week, was written by one of the students at the Gaetano Salvemini Science High School in Bari, who participated in PON 0009707 -FSE and FDR – Learning and Sociality: ERGASTERIO – Laboratories for Competence – Module: UmanaMente-02. The students worked on the topic of scientific journalism and more generally with the burning question of correct information and dissemination. Led by the director of “Ambient & Ambienti” Lucia Schinzano, they became familiar with the essential aspects of journalistic writing and especially by writing “green” themes. They searched for sources, discussed them, turned them into articles, and experimented with web journalism. The articles were all accompanied by video interviews that the students did with their own funds, and with a lot of good will, and was in this part of the journey followed by journalist Ruben Rotundo. The last phase consisted of editing. Articles have emerged which show a simple but highly motivated approach and which have had the benefit of making children more aware of what they see, hear or read. And it’s a great achievement.

In the face of the pollution challenge, an increasingly popular solution is electric cars, which, thanks to their non-combustion engine, do not emit greenhouse gases that are harmful to health, unlike normal petrol cars.
by Mercedes Mantovani
To tackle climate change, the automotive industry is ready to replace old petrol cars with a new invention, electric cars, which aim to transform our mobility. But how good are electric cars for the climate?
The transport sector is an important source of greenhouse gases which changes the climatic balance, responsible for 30% of emissions of CO2 at European level. About 72% is produced by road transport, and 61% of this by cars alone. At the same time, the gases issued by passenger cars they are also a significant proportion of air pollutants that are dangerous to human health and the environment. This phenomenon occurs mainly in cities.
According to a study published by The Lancet Planetary Health on pollution-related premature deaths in more than a thousand European citiesBrescia and Bergamo are the ones where the fine particles matter P.M.2.5 or even said poor thin make more victims, followed by Vicenza and Saronno, while the Italian cities where the pollution from NO2 most striking is Turin and Milan.
Decarbonizing mobility and reducing pollutant emissions is therefore crucial to combating the climate crisis and ensuring citizens’ health and environmental balances.
According to the plans from European Green Dealwhich aims to achieve climate neutrality, greenhouse gas emissions from transport will have to be reduced by 90% over the next thirty years; Unfortunately, however, the current trend is going in the opposite direction. Faced with the challenge of decarbonization is an increasingly popular solution electric cars which, thanks to their non-combustion engine, do not emit exhaust gas.
Electric motors: advantages and disadvantages
According to the European Environment Agency, electric motors more efficient than internal combustion engines and they waste less energy Plus produces electric cars less polluting atmospheric compared to petrol or diesel cars, and can reduce noise pollution as they generally are less noisy. But is it really worth taking an electric car? let’s see pros and cons of these cars.
An advantage of electric cars isreduced environmental impact. Driving an electric car produces no exhaust fumes and no additional smog enters the air, no combustion occurs and no CO2 or harmful greenhouse gas. One drawback is the way energy is produced for these vehicles; in fact electric vehicles are ecological but need energy to recharge the batteries; the latter is produced in central electric, which in turn generates pollution. Therefore, electric cars are only one Part of regeneration process in place.
For a greener world
For a truly greener world, we are also working to improve systems and infrastructures that in the future they should only exploit clean energy taken from renewable energy. In fact, to ensure that electric cars become completely green, we should use renewable sources to provide energy to these vehicles; but a solution to this problem has not yet been found.
From intentions to facts
Most Italians are willing to buy these electric cars, but to go from intentions to facts, they are waiting for it the price drops markedly. The turning point could be in 2030when a cancellation of the current price gap, and therefore more affordable prices. In 8 years, the new electric cars can therefore make up half of the total number in circulation in Italy.
