It’s real. Greenhouse gases like carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are elements that occur naturally in the Earth’s atmosphere. However, since the Industrial Revolution, human activity has caused more and more greenhouse gases to be released into the atmosphere as pollution, especially CO2.
The hole in the ozone layer has closed up, but we’re still being reckless with our environment and the ozone is still at risk due to both domestic and industrial pollution. Walk to the shops instead of driving, don’t buy food with heaps of plastic packaging and recycle!
