WATCH: 7 Awesome Money-Saving Tricks You Can Do Around The House. Watch and Learn!

It's easy to become so mired in daily routine that we grow oblivious to the amount of money we're needlessly wasting around the house. However, there are actually a myriad of money-saving techniques that anyone can employ at home, and these tricks require very few extra supplies (or additional effort). Watch as the thrifty folks at Household Hacker demonstrate how to pinch pennies and live just a little bit wiser fiscally on the domestic front.

Most people probably don't even consider the water they use when flushing their toilet, hence the practical need for a one-liter bottle inside the tank. However, there are additional ways you can conserve water that don't require an empty Aquafina container. For example, Water Use It Wisely explains that washing dark clothes in cold water conserves energy and water (not to mention it preserves the garments' colors). And even small, seemingly insignificant actions like scraping your dishes in the trash rather than rinsing them in the sink make a huge difference. For example, did you know that turning off the water while shampooing your hair can actually save 150 gallons of water per month?

But just why does it matter? Well, for starters, the UN estimates that 700 million people already suffer from water scarcity. That statistic may seem like a distant, irrelevant fact to a lot of people who have no issues getting clean water from their kitchen sinks. However, the UN also estimates that half of the world's population will be living in "high stress water areas" by 2030. That's only 15 years away and very much within the realm of our lifetimes.

That's why nifty little life hacks like this series from Household Hacker are helpful in teaching us to save and conserve.
