When doing laundry, we've been conditioned to separate dark colors from whites. But when it comes to treating your white laundry, be sure to understand that not all white garments are the same. When it comes to any garment that is not 100 percent cotton -- including polyester, spandex or nylon blends -- even if it's blended with cotton, these pieces need to be separated. Synthetic-blend white pieces won't brighten with the addition of bleach. In fact, they actually turn yellow. Instead, wash them in cold water and add white vinegar, which has a natural acid to help neutralize odors and brighten whites.

Planting a tree is one of the best ways to help offset global warming, since trees are like living sponges: They absorb carbon dioxide emissions and, of course, give oxygen back to the atmosphere. But not all trees are the same, and there are some leafy types that absorb more than others. Depending on where you live, there are certain "green heroes" you should consider when planting a tree. Varieties like the yellow poplar, silver maple, oaks, horse chestnut and red mulberry are powerhouses that provide shade and shelter, and are resilient in all types of growing conditions.

When you are doing laundry, be sure to pay special attention to your kitchen towels. Since they are used for myriad tasks around the kitchen -- from cleaning spills to drying dishes -- they also tend to be moist most of the time. A wet towel is a breeding ground for harmful bacteria. The next time you wash your kitchen towels, consider drying them outdoors on a bright, sunny day, and not in your dryer. The ultraviolet rays from the sun will naturally disinfect the towels. Let the towels dry completely, and even leave them in the sun for a few extra hours. The longer you leave them out, the more they will be disinfected.
