Global gas 2 PP

Human activities have increased the levels of most  greenhouse gases. Nitrous oxide is released through soil cultivation, fossil fuel combustion, nitric acid production and biomass burning. Methane is produced through decomposition of landfill waste, agriculture, and manure from livestock. And carbon dioxide is released from deforestation, land use changes and burning fossil fuels. When these gases are released there is no easy way to reverse the effects; for example, carbon dioxide can take hundreds of thousands of years to dissipate through chemical weathering or rock formation. The main way carbon dioxide leaves the atmosphere is by being absorbed into the oceans which causes many problems. Global warming is caused by greenhouse gases and is a huge issue that has huge consequences.
