Summarize the following:
It's an easy switch that makes a big difference. Using toxic chemicals like bleach and ammonia to clean your home is not only bad for the water supply, it's not necessary. Natural cleaners are just as effective at getting the house clean, and you don't have to worry that you're contributing to water pollution when you use them. The Environmental Protection Agency (EPA) provides a list of cleaning products (as well as a variety of other products) that are considered "green," meaning they won't pollute the water supply. See epa.gov/greenerproducts. Common household supplies like white vinegar and baking soda can be used for everything from washing windows to scrubbing bathroom tiles, and they're completely non-toxic. Never pour something that isn't biodegradable down the drain. When it is necessary to use something that's toxic to the water supply, such as paint or ammonia, take care to dispose of it properly. If you're not sure how to get rid of something, check your local government's website or contact your sanitation department to find out how toxic waste should be disposed of in your community. The following materials should never be poured down the drain: Paint Motor oil Cleaning solvents Ammonia Pool chemicals Medication is made with a variety of substances that can be detrimental to the water supply. If you have leftover medication, look into local "take back" programs that allow you to turn in medication so it can be disposed of properly. That way it won't end up back in the drinking water, where it can harm people and animals. Flushing items that don't break down, like diapers, wet wipes, and plastic tampon applicators can cause problems in the sewer system. These items will eventually end up in local streams, rivers and other bodies of water, where they can harm fish and other wildlife. Instead of flushing them down the toilet, throw them away. You can also help by using cloth diapers, recycled toilet paper and biodegradable tampons, which reduces the number of items that end up in the landfill. Conservation is an important way to help preserve water as a global resource. Treating water so it's clean enough to drink and use around the house requires a lot of energy, so it's important to conserve as much as possible, especially in areas where droughts are occurring. Adopt the following habits to conserve more water around your house: Take showers instead of baths, since baths require more water. Turn off your faucets when you aren't using water, such as when you're brushing your teeth. Don't overwater your lawn. Make sure lawn sprinklers are turned off when it rains. Water your garden before the sun comes up or after it sets to reduce evaporation, which leads to water waste. Since it isn't biodegradable, plastic often ends up collecting in rivers, lakes, and oceans when it has nowhere else to go. The Great Pacific Garbage Patch, for example, is a huge vortex of trash, mainly plastic, that has collected in the ocean since it has nowhere else to go. This trash endangers marine life and affects humans as well. Whenever possible, use glass or cloth containers instead of plastic.

summary: Use fewer chemicals to clean your home. Dispose of waste properly. Don't flush medication. Don't flush trash. Conserve as much water as possible. Avoid using plastic.

The main way people add each other in Snapchat is by trading usernames. This allows you to add people that aren't in your phone's contact list. There is no way to add someone to Snapchat using an email address or real name. You'll need to ask the person what their Snapchat username is. Note - Snapchat has two names: Display names and Usernames. The Display name is the name that appears first to other people, and can be changed, but is not used to add someone. The Username is the user's permanent account name. You'll need the Username to add someone. You'll see your Snapcode, display name, username, and Snapchat score. This will open the Add Friends menu. This will open the user search. You cannot enter a partial username and have Snapchat finish it for you. You must type the entire username to find the person. You can only search by Snapchat username; you cannot search by real name, phone number, email address, or any other name or address. If you want to add someone using a phone number, add them to your phone's address book first then follow the steps in the previous section. This will add the person to your friends list. This button will only appear if you've typed the person's entire username correctly. The other person may need to add you back before you can start talking to each other and send Snaps back and forth. This depends on the other person's privacy settings.

summary: Find out your friend's username. Swipe down anywhere on the Snapchat camera screen. Tap "Add Friends." Tap "Add by Username." Type the full username of the person you want to add. Tap the "+Add" button next to the user. Wait to be added back.

Many fears are based in false beliefs or catastrophic thinking. When you see a spider, you may immediately have a belief that says that the spider will harm you, and that you will die. Identify these patterns of thinking, and start to question them. Do some online research and understand your actual risk versus perceived risk. Recognize that the worse-case scenario is highly unlikely. Begin to re-structure your thoughts to not engage in catastrophic thinking, and start to talk back to those thoughts. When your fear arises, pause and reflect on your actual risk. Talk back to your negative thoughts or false beliefs and say, "I recognize that some dogs are vicious, but the vast majority of dogs are gentle. It is unlikely I will get bitten." After you have confronted your false beliefs, begin to expose yourself to the fear. Oftentimes we're afraid of something because we haven't been exposed to it very much. "Fear of the unknown" is a commonly used phrase to describe the automatic aversion people feel to something that's different. If you're afraid of dogs, start by looking at a badly drawn doodle of a dog done in silly colors. Look at it until you feel no fear response. Then, look at a photo of a dog, then a video of a dog. Examine it until no fear response exists. Go to a park where you know one or a few dogs will be on-leash and watch them until you feel no fear. Go to a friend's house who has a dog and watch him interact with a dog until no fear response is elicited. Ask a friend to let you touch or pet his dog while the dog is restrained by your friend until you feel neutral. Finally, be near a dog and spend one-on-one time with a dog. The power to label your emotions is beneficial for self-understanding and emotional intelligence. It also appears that engaging with a fear and verbalizing your fear has incredible power to help you overcome fears and regulate emotions. Researchers had spider-fearful individuals exposed to a spider, and participants that labelled their fears ("I feel very scared of this spider") had a lower fear response the following week when exposed to a different spider. Running from fears never improves the way you feel about a fear. Next time you experience a fear, verbally engage the fear, using words that describe your fear and anxiety. When your body experiences fear, lots of triggers ready your body for a "fight-or-flight" action response. Learn to override this response by counteracting with relaxation techniques. Relaxation tells your body that there is no danger and that you are safe. Relaxation can also help you cope with other stress and anxiety in your life. Try deep breathing exercises. Focus on your breath, and start counting each breath: four seconds inhale, then four seconds exhale. Once this is comfortable, elongate your breath to six seconds. If you notice your muscles tensing, be conscious to relax them. One way to do this is to clench all the muscles in your body for three seconds, then relax them. Do this two or three times to melt stress throughout your body.
summary: Identify false beliefs. Try gradual exposure. Practice engaging with the fear. Learn relaxation techniques.
