Saving the world may seem like a daunting task.

But every little bit helps— even minor changes in the home and workplace can positively impact generations to come.

Dr. Alan Greene, practicing pediatrician and an authority on family health issues, offers a few simple steps to help people live a greener and healthier lifestyle.

•Eat wisely. Most pesticide exposures occur during the winter months, when more produce is imported. Choosing foods grown locally or within a 100mile radius has the lowest overall impact on the environment.

•Update air filters. According to the EPA, the air inside the average home contains two to five times more pollution than outside air.

This is especially an issue in the winter, when people spend more time inside and keep their homes more sealed. Changing or cleaning the heater filters can make a big difference and save on energy costs, too.

•Use nontoxic cleaners. Winter may be the most important season in which to choose products that don't emit harmful fumes.

•Open a window. Help reduce indoor air pollution by opening a window on a sunny afternoon.

•Consider houseplants. They excel at removing airborne chemicals. Particularly effective varieties include Boston fern, areca palm, lady palm, bamboo palm, rubber plant, English ivy, ficus and peace lily.

•Leave shoes at the door. Encourage guests to remove their shoes when entering the house. A basket of slippers kept by the door can ensure that everyone's feet stay cozy. Place large mats at entrances to remove particles and other pollutants from the shoes.

•Select LEDs or compact fluorescent lightbulbs. They last longer, reduce greenhouse emissions and save energy and money on the electric bill.

•Consider packaging when buying items. Buy in bulk whenever possible. Avoid items that are wrapped in excessive packaging, from gifts to daily items. Some companies now offer a more concentrated formula packaged in smaller containers to reduce excess materials.

•Recycle. Look for products with packaging and materials that can be easily recycled and select products made from recycled materials.

•Green wash, literally. According to Project Laundry List, approximately 35 billion loads of laundry are washed each year in the U.S. When possible, use cold water and only run a load when the machine is full.
