ovements, ride-sharing, alternative transportation, and tree planting programs are just some of the community-based solutions to reducing air pollutant and gas emissions. A typical automobile will emit more than 40% of its own weight in common air pollutants in one year, and four times its weight in greenhouse gases. So for those necessary trips by car, make sure that it is a well-tuned, energy-efficient model! Also, avoid idling our engines, as restarting an engine uses less fuel than ten seconds of idling. Other actions we can take at home and at work include: Turn off energy-using equipment (lights, computers, or any machinery) when it is not in use. Make your home more energy efficient through improved insulation, caulking and weather-stripping. Recycle, since it takes much less energy to create a new product using recycled materials than using raw materials. Compost kitchen scraps and yard waste, because organic waste in landfills creates gases that contribute to climate change. Plant trees around our home. It's a natural way to insulate, and trees help clean the air and slow climate change....
