Ukraine faces significant environmental pollution problems, including air, water, soil, and deforestation. Air pollution in major cities is caused by emissions from industry and motor vehicles. Water pollution affects bodies like the Black Sea due to waste dumping and oil spills. Deforestation, such as in the Carpathians, reduces carbon absorption and increases flood risks. The Chernobyl nuclear accident in 1986 contaminated large areas of Ukraine, Belarus, and Russia with radioactive fallout. Proposed solutions include better waste management, pollution controls, and prevention of emergencies to improve Ukraine's environment.
