"WORLD PRACTICES OF AIR, WATER, SOIL PROTECTION, WASTE MANAGEMENT"

the topic that was presented by Professor of the Department of Ecology Olena Mitryasova on April 19, 2023, to the participants of the Interdisciplinary Studies "European Green Dimensions" held with the support of the EU Erasmus+ Jean Monnet Programme.
  During the presentation, the following issues were highlighted: the main ecological problems of atmospheric air; the "greenhouse effect" of the atmosphere - the cause of climate change and methods of fixing greenhouse gases; agriculture and methods of reducing greenhouse gas emissions; main ecological problems of water resources; sources of pollution of the World Ocean and internal waters; wastewater treatment methods; global innovative practices of water treatment and rational use of water resources; soil resources of the Earth and the main ecological problems of soils; perspective practices of soil protection; current practices of processing and disposal of waste.
The topic is extremely broad, so the key aspects were fragmentarily outlined by the speaker; the listeners' attention was focused on the main objects of the environment, which are: air, water, and soil. The issue of global waste disposal practices was not left out of consideration. For example, recycling one plastic bottle saves energy, which is enough for 4 hours of operation of a 100 W light bulb. The bottle recycling process pollutes the air 20% less and the water 50% less than its production from primary raw materials. More than 1.6 million people in the world are employed in the recycling industry, and the annual contribution of the recycling industry to the global GDP for the next 10 years is projected to be 400 billion dollars.
All questions on the topic aroused interest among listeners.
