Starting Oct. 1, my new television show "Naturally, Danny Seo" will air every week on NBC. The show brings the pages of both my magazine and this column to life, and I'll be offering healthy recipes, easy upcycling projects and have a regular segment sharing my best Do Just One Thing tips. The show will air for a full 52 weeks, and we will highlight amazing designers, entrepreneurs, community activists, chefs and more who are changing how we marry the worlds of style and sustainability. Hope you can tune in!

If you've driven your car more than 30,000 miles, it's time to replace the spark plugs. Over time, spark plugs can become covered in carbon deposits, which makes them work harder and decreases your car's overall fuel efficiency. When your car misfires -- when the engine stops for a brief second and keeps on going -- it's a sure sign that your spark plugs need replacing. Misfires increase exhaust emissions, which can negatively impact your overall miles per gallon, too.

Many dog shampoos or washes are loaded with chemicals that can irritate their skin and cause even more problems. One way to avoid chemical shampoo cocktails is to make your own all-natural mix using Castile soap, baking soda and apple cider vinegar. In between washes, generously sprinkle baking soda all over your dog's dry fur, and massage it in. Brush through the hair to get out the baking soda. The alkalizing nature of baking soda won't irritate dogs' skin, and it will naturally keep their fur deodorized and smelling fresh.
