How can we help the earth aviod global warming?

The biggest cause of global warming is the carbon dioxide released when fossil fuels like oil and coal are burned for energy. So when we save energy, we fight global warming (and save money, of course). Here are some easy steps we can take:
Replace a regular incandescent light bulb with a compact fluorescent light bulb.
Clean or replace filters on air conditioners.
Choose energy efficient electrical appliances when making new purchases.
Look for the Energy Star label on electrical appliances to choose the most efficient models available.
Do not leave electrical appliances on standby (e.g. TV).
Cover the pots while cooking.
Use the washing machine or dishwasher only when they are full.
Take a shower instead of a bath.
Use less hot water.
Be sure we are recycling at home (e.g. put bottles and cans in recycle bins).
Buy recycled paper products.
Choose products that come with little packaging and buy refills when we can.
Reuse shopping bags.
Reduce waste.
Plant more trees.
Switch to green power (e.g. wind and solar power).
Buy fresh foods instead of frozen food. (Frozen food uses 10 times more energy to produce.)
Buy organic foods as much as possible.
Eat less meat.
If we need a car, choose an efficient vehicle.
Drive smart. Get the engine tuned up and keep the tires inflated -- both help fuel efficiency.
Drive less. When possible, choose alternatives to driving (public transit, biking, walking, carpooling)

Reuse energy

There are five categories of actions that can be taken to mitigate(=avoid) global warming:

- Reduction of energy use (per person)
- Shifting from carbon-based fossil fuels to alternative energy sources
- Carbon capture and storage
- Geoengineering including carbon sequestration
- Birth control, to lessen demand for resources such as energy and land clearing
