3. Global Warming

4. Cause
– Global warming is primarily a problem of too much carbon
dioxide (CO2) in the atmosphere—which acts as a blanket,
trapping heat and warming the planet. As we burn fossil
fuels like coal, oil and natural gas for energy or cut down
and burn forests to create pastures and plantations, carbon
accumulates and overloads our atmosphere. Certain waste
management and agricultural practices aggravate the
problem by releasing other potent global warming gases,
such as methane and nitrous oxide.
