Having passed the environmental assessment located in Unit 6, I got 12 points. Based on the result, I can conclude that I need to pay more attention to conscious energy saving (electricity, heat) and study waste recycling more deeply. In my opinion, it is essential to research and participate in environmental conservation projects, as such activities will help to learn the topic better and contribute to it.

Air pollution appears to be one of the main factors affecting the environment. It can be considered as any change in its properties or composition that has a deleterious effect on plants or entire ecosystems, on animal or human health. Population growth in big cities is increasing every year; more people will need vehicles, industrial plants, and food grown with chemical fertilizers in a few years. The birth rate and health of a megacity’s future inhabitants will depend on the city’s environmental condition. The problem is essential to the world and needs to be studied in detail, and new ways of solving it need to be found.
Atmospheric pollution is one of the global warnings of humankind. It is about the threat of oxygen depletion, which is necessary to sustain all life on earth, and climate change, destroying the planet. According to the WHO, 9 out of 10 people breathe air with high pollutants (CCAC secretariat, 2018). Among the most important sources of atmospheric contamination are natural and anthropogenic. Chemical air pollution due to the emission of many toxic oxidized gases is exceptionally high (Manisalidis et al. 2020). Often a mix of these types of contamination is present at once, cleaning and decontaminating the air envelope more difficult. Disregarding nature brings humanity’s demise, the destruction of the face of the planet closer.
Depending on the degree of atmospheric pollution, different cleaning methods are chosen, and other ways of solving the problem are considered. Based on the material studied, all forms can be divided into three main directions. These include developing strategies to use fuels as waste-free as possible, improving the quality of vehicles and industrial fuels to reduce their waste, and increasing the number of green trees to purify the air from impurities. This problem is now becoming more and more relevant and vital. That is why the search for new ways to solve the pollution problem and the wide use of scientists’ inventions will improve the environment.
