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.

Reusable water bottles are good for the planet, since you can use them over and over again. But reusable bottles need to be taken care of to help you stay healthy. If you don't wash your reusable bottles, the interior cavity can become a breeding ground for unhealthy bacteria. Make sure to fully dry the bottles after you wash them, too, otherwise, they can make you sick the next time you fill them up. Another idea: Place clean bottles back into the fridge. The cold air inhibits the growth of bacteria. And on a hot summer day, the bottle will keep your water chilled even longer.
