Without its oxygen content the Earth's atmosphere would be composed almost entirely of nitrogen and would be chemically inert; oxygen causes the atmosphere to be chemically active (and breathable by humans).
global warming would be decreased (apex)
Humans are contributing to global warming (by burning fossil fuel and cutting down forests) and global warming is CAUSING climate change.
No, Hurricane Katrina caused flooding and terrible damage to humans and property, but it did not cause global warming. Global warming is caused among other things by man burning fossil fuels (coal, oil and natural gas) and putting greenhouse gases into the atmosphere.
Earth's magnet field shields humans from dangerous radiation form the sun and protects the earth's atmosphere form the solar wind. Without the magnetic field, there would be no human life on earth.
The quality of air depends upon humans. What humans do will reflect in the atmosphere.
CO2; Carbon Dioxide
Lots.
There is no such thing as "a global warming" global warming only happens to earth because human and our unruly decrease in the earths resources. HUMANS cause global warming.
They burn high in the earths atmosphere.
sexy
with co2 and gassed rissing into the atmosphere
humans use products containing CFCs which accumulate in the atmosphere.
Almost all the industrial activities leads to production of gases such as carbon di oxide,carbon monoxide and other green house gases.... it's quite obvious that green house gases increase the temperature of the earth's atmosphere by blocking and re-radiating the I-R rays into the atmosphere that have been reflected from the earth's surface previously .......
our activities, movements and settlements shape the Earths surface.
Mainly by humans polluting atmosphere and by global warming we caused
They release gases into the atmosphere that destroys the ozone layer (which protect us from the direct sun rays) and causes global warming.
