CO 2 and methane are greenhouse gases , trapping outgoing long wavelength radiations inwards the atmosphere as well as warming the Earth. Increased concentrations of these gases are causing global warming . SO 2 is produced when coal as well as other fossil fuels burn. SO 2 and nitrogen oxides dissolves as well as react inwards H2O droplets inwards the atmosphere, as well as autumn to the soil every bit acid rain . This leaches aluminum ions from soils, as well as kills plants as well as aquatic organisms. Fall-out from accidents at nuclear reactions emits ionising radiation, which damages deoxyribonucleic acid as well as tin travail mutations, cancer as well as radiations burns. Deforestation reduces the sum of CO 2 that is taken out of the atmosphere for photosynthesis, as well as then may increment global warming. Combustion of the felled trees releases CO 2 into the atmosphere. Deforestation ev...
