It's not hard to maintain a lush, green lawn and to do it without the aid of chemical herbicides or fertilizers. One of the easiest ways to remove invasive weeds like dandelion is to use a chemical-free alternative called corn gluten. Not only does it kill weed seeds, it's also so safe that after application, pets and people can play on the lawn. Corn gluten is a byproduct of cornstarch and corn syrup production and is non-polluting, so homes near waterways like lakes and streams won't risk polluting water by using it.

According to the Natural Resources Defense Council, one of the biggest culprits of water pollution is runoff from homes. The source? Impervious surfaces like cement, which directs water onto roads and rivers, which then picks up toxic chemicals, dirt, trash and disease. Choose wood decking and interlocking bricks and paver stones for walkways instead of concrete. This allows water to drain into the soil. And if you can redirect downspouts away from driveways and onto grassy areas, that also helps prevent unnecessary water runoff.

Walking through the vitamin and supplement aisle at your local supermarket can be an overwhelming experience. Since most stores aren't stocked with experts to help you navigate the products, it can be impossible to know what to take to improve your health. The homeopathic company Boiron has taken a high-tech step so you can figure out what you need on your smartphone. The free app answers simple questions, like if you're looking for natural help with allergy, cold and flu, eye care or digestive problems. Then it asks for symptoms and offers a product option that will work for you.
