Q: Many people either don't know about or don't understand sky glow and the negative impacts of too much light at night. Be an ambassador and explain the issues to others. You will then have growing ranks of night sky protectors. Show them images of what the night sky looks like without light pollution. NASA has an assortment of images that can help argue your case by showing the beauty of the night sky. Fighting light pollution requires a group effort. Even a few houses in a neighborhood can make a noticeable difference in night sky visibility.  Reach out to your neighbors in a friendly manner. Consider sending them a letter or bringing it up during a block party. Many people are unaware that their lights are harmful or distracting. Suggest alternatives to their existing lights, and offer to help them choose and install replacements. Suggest that they change local street lights to more eco-friendly variations.  There are a variety of new street lamps that are designed to reduce light pollution as well as cut back on costs. Several awareness groups dedicated to light pollution have been created in recent years. They offer a way to put your head together with like-minded individuals to create change on a larger scale. These awareness groups provide additional tips for eco-friendly lighting, as well as which lighting products are healthiest for the environment. Many buildings have begun building “green” in order to become more eco-friendly. If the building where you work is renovating or if new construction is starting in your neighborhood, ask the party responsible about their plans to combat light pollution. Direct your employer to organizations such as Leadership in Energy and Environmental Design (LEED). LEED recognizes and certifies buildings that build green, which can help bring some positive attention to your company.
A: Spread the word to your family and friends. Reach out to the neighborhood. Write a letter to your city council. Join a light pollution awareness group. Support green buildings.

Q: Take a piece of denim patch that you would use on a pair of jeans. Cut it slightly larger than the tear in the leather, and round the edges of the patch. Use tweezers to gently stuff it into the tear so it lays flat under the tear. Use a flexible glue for plastic or vinyl and apply to the patch. Squeeze the tear closed over it.  Rather than just gluing the tear closed, which will cause it to be a dent, placing a patch under creates a new layer under the leather which will hold it together and keep it smooth. You can stop at this point and the tear will be repaired. If you want to improve the look, you can put a little bit of superglue in the tear, gently sand while it is still wet which adds dust to the glue, and then restore the color with leather color restoration. Leaving something heavy on furniture can cause a dent. Get a heat gun, or use a hair dryer if you prefer. On the low setting, heat up the dented area of the leather. Gently use both of your hands to stretch the leather outward from the dent. Repeat the process of heating and stretching until the dent has been removed or reduced in appearance. Go to a furniture store, a hardware store, or look online to buy a leather color repair kit. This will typically include a cream or balm that you gently rub into your furniture. You'll choose a color that matches as best as possible. Take a cloth, put some of the cream on it, and gently rub it into the spots that are most faded.
A: Fix torn leather with a patch. Remove dents with heat. Restore the color of faded leather with a repair kit.

Q: Hermit crabs love to dig, tunnel and bury themselves.   Not only is playing in substrate fun for your crab, the substrate provides the right environment for your crab to molt (i.e. shed exoskeleton, grow).  The depth of the substrate should be 3 to 4 times the size of your crab's shell and be able to retain moisture.  If your crab is the size of a dime, penny, or quarter, you will need at least 6 inches of substrate. If your crab is the size of a golf ball, use 6 to 8 inches of substrate. If your crab is the size of a tennis ball, use 8 to 10 inches of substrate. If your crab is larger than a baseball, use at least 12 inches of substrate. Any type of sand is fine for your crab as long as it is clean. Most sand that you buy will be pre-washed and/or pre-sanitized.  Pour some of the sand into a small bowl before you put it in your crab's tank and check for insects.  If you notice any strange smells when you open the bag of sand, do not put the sand in the tank. The sand may be moldy. Sand is very affordable and your crab will enjoy playing in it. Coconut fiber (i.e. Forest Bedding, Eco-Earth) comes as a hard brick when you purchase it, and it must be prepared before you place it in the tank. Place the brick in a large bowl and fill the bowl with water until you can break the brick apart with your hands.  Add the coconut fiber to the tank while it is moist.  Your hermit crab will probably eat some of the coconut fiber.  This is perfectly fine as it contains minerals that they need. You can also use pre-prepared salt water to fix your coconut fiber. Coconut fiber attracts fungus gnats.  If you notice tiny black bugs in the tank, you need to clean the tank and replace the substrate. You can also combine sand and coconut fiber. Use a 5:1 ration of sand to coconut fiber.
A:
Make sure the substrate is deep enough. Use sand. Use coconut fiber.
