We have to reduce the energy in our homes and offices. For examples, turn off your computer, printers and other electronic devices when not in use. Also we have recycle household waste such as papers, cans plastic and other materials.
In our homes, we have to turn off the water heater when going on vacation. Also we have to replace all lights that consume more energy and put fluorescent lights. These lights use less energy and we will prevent the emissions of carbon dioxide. We can use bicycles more often because they don't burn a single fossil fuel carbon atom.
