They are covered in a total of 900 trees, 5,000 shrubs and over 11,000 other plants!Īpart from looking really cool, vertical forests have many potential environmental benefits. ![]() The two towers in Milan are residential towers but with a difference. Vertical forests may look like the work of science fiction, but thanks to Italian architect Stefano Boeri the first vertical forest towers, the ‘Bosco Verticale’ were completed in Milan in 2014. So how can we reduce air pollution levels in our cities? What inventions and innovations are appearing to help reduce this big environmental issue? 1) Vertical Forests Low level ozone (O 3) a secondary air pollutant formed when other gases mix together, posing a risk to human healthĪccording to the World Health Organization (WHO) around 3.8 million premature deaths are attributed to air pollution, around 80% of which are due to heart disease and the other 20% due to other illnesses and cancers.īut as you now know, the effects to the wider environment from air pollutants is also vast, with climate change and acid rain having damaging effects too.PM2.5 which has hit the headlines recently, refers to any particulate matter with particles measuring less than 2.5 micrometres Airborne particulates (such as PM2.5) which are solid or liquid particles in the air, including all sorts of things from soot to dust that become suspended in the air.Carbon monoxide (CO), an extremely deadly odorless gas found in exhaust fumes.Methane (CH 4) and other similar substances mainly formed by rotting organic matter in landfills.Sulphur dioxide (SO 2), mainly formed by burning coal and leads to the formation of acid rain.Nitrogen Oxides, including nitrous oxide (N 2O) is another greenhouse gas almost 300 times as potent as CO 2.Carbon dioxide (CO 2), one of the most well-known greenhouse gases and contributors to climate change.It simply has to be “a substance in the air that can either have damaging effects on human health or the wider environment”.Īs a result of these processes a number of different air pollutants are formed: What are the main air pollutants?Īn air pollutant doesn’t have to be something that has a direct effect on human health. In lower-income cities, incineration of solid waste and agricultural waste are also big contributors. ![]() What causes air pollution in our cities?Īir pollution from cities is mostly a result of increased numbers of cars and other vehicles burning fossil fuels along with power plants and industrial complexes. But perhaps one of the most worrying (in terms of public health) is the issue of air pollution. This pollution comes in many forms, from plastic and other waste littering the streets, to toxic chemical substances entering waterways. With pollution being one of the most concerning. This increase in human density in these areas brings with it a host of potential environmental issues. With the UN predicting this figure will rise from it’s current level of 55% to almost 70% in the coming decades. The number of people now living in cities across the globe is as high as it has ever been.
