# 155 Summary Of Human Together With Ecosystem

CO₂ 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.

• SO₂ is produced when coal as well as other fossil fuels burn.

• SO₂ 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 CO₂ that is taken out of the atmosphere for photosynthesis, as well as then may increment global warming. Combustion of the felled trees releases CO₂ into the atmosphere. Deforestation every bit good destroys habitats for animals, maybe leading to their extinction. It increases soil erosion as well as flooding.

• Water pollution past times fertilisers or raw sewage tin travail eutrophication, inwards which large populations of aerobic bacteria form, reducing the sum of dissolved O₂ in the H2O as well as making it impossible for nearly animals to alive there. Other chemic wastes, such every bit heavy metals, tin every bit good travail H2O pollution.
