If a tree falls in the forest, does it make a sound?
Sure does, and a company by the name of Rainforest Connection hopes one of its cell phones will be around to hear it.
The San Francisco nonprofit plans to install used Android smartphones in rainforests to help curtail illegal logging.
Here's how: Ambient sounds in the rainforest will be continuously recorded and screened using the phones' microphones and onboard software. Any noises that match the sound-signature of a chainsaw will trigger an alert, providing rangers with information to intervene and stop the deforestation, according to Rainforest Connection's website.
"We can find out how much forest has been cut using satellite images, but we find out after, so we cannot trace when it happens," Dwiati Novita Rini, a rainforest rehabilitation worker in Sumatra, said to New Scientist, explaining the phones' potential to enable real-time action.
Alerts can be sent using cell networks that already exist wherever the devices are installed. In the Indonesian jungle, for instance, home of a small batch of phones the company is installing this month, unlimited cell phone data can be had for just $2.89 per month. (According to a 2012 BBC report, even the furthest reaches of the Amazon now boast cell service.)
The phones are powered using solar energy and -- eventually -- will be simple enough for locals to install them on trees themselves. Fifteen devices are currently being deployed in western Sumatra's Air Tarusan reserve in a limited beta test.
Each phone covers a circular area of about a third of a square mile, meaning 15 phones are insufficient for all of Air Tarusan's 96 square miles of old-growth forest, but it's a start.
In an email to The Huffington Post, Topher White, the founder of Rainforest Connection, explained that, though the project is in a trial phase, "from a technical standpoint it is very well advanced." White added that all software and hardware, excluding the phone's internal components, are open-source.
Assuming the trial goes as planned, Rainforest Connection hopes to collect and recycle used smartphones for deployment throughout Indonesia and South America. In the meantime, there's only one question for illegal loggers in western Sumatra: Can you hear us now?

1. <a href="http://www.energystar.gov/index.cfm?c=products.es_at_home" target="_hplink">Energy Savings For Your Home</a> <br> The average home spends almost 20 percent of its utility bill on cooling. These cooling bills can be lowered by simply changing out incandescent light bulbs with EPA's Energy Star qualified lighting, which use less energy and produce approximately 75 percent less heat. Raising your thermostat by only two degrees and using your ceiling fan can lower cooling costs by up to 14 percent too.
Obey the speed limit; go easy on the brakes and avoid hard accelerations; reduce your time idling; and unload unnecessary items in your trunk to reduce weight. If you're not using your removable roof rack take it off to improve your fuel economy.
Skin cancer is the most common form of cancer in the U.S. and is the most common cancer among 20 to 30-year-olds. Remember to practice safe sun habits.
Americans take almost two billion trips to the beach every year. Beaches are a place to play, watch wildlife, fish, and swim. Learn more on how to plan a safe trip to the beach and check out state specific beach advisory and closing notifications.
The AirNow app gives location-specific current air quality information to use to protect your health when planning daily activities and the Ultraviolet (UV) Index app provides daily and hourly forecast of the UV radiation levels from the sun so you can better prevent overexposure to the sun.
Almost 40 years ago, EPA's Documerica project captured thousands of images across the nation as EPA's work was just beginning. Now it's your chance to mark the progress and submit environmental photos to EPA's State of the Environment photo project.
Mosquitoes and ticks can carry diseases but you can protect yourself by choosing the right repellent and using it correctly. Read the product label before using; apply just enough to cover exposed skin and clothing; and look for the protection time that meets your needs. Children can use the same repellents as adults unless there is a restriction on the label.
8. Water Wisely
A large percentage of water we use at home is used outdoors. As much as 30 percent of that outdoor water use can be wasted due to evaporation by watering in the middle of the day. Water in the morning when winds are calm and temperatures are cool. Look for the new WaterSense labeled weather-based irrigation controller that uses local weather data to determine whether your sprinkler system should turn on.
If you're going to wash the car, deck, boat, or RV- be sure to look for the Design for the Environment (DfE) label to quickly identify and choose cleaning products that are safer for families and also help protect the environment. Look for the DfE label on grill cleaners as well.
About 90 percent of people's time is spent indoors. While inside this summer, make sure to free your house of mold, test your home for radon, check your carbon monoxide detector and ask those who smoke to go outdoors.
On average, America's 47,000 hotels spend more than $2,000 per available room each year on energy. Look for an Energy Star certified hotel--they perform in the top 25 percent of hotels nationwide, use an average of 35 percent less energy and emit an average of 35 percent less greenhouse gas emissions than peers.
Each year, Americans generate millions of tons of waste in homes and communities but it's easy to reduce, reuse, and recycle. Recycled items such as glass can be used in roadway asphalt (glassphalt) and recovered plastic can be used in carpeting and park benches. Learn what you can do to waste less.
13. Season Firewood
Summer is a great time to season firewood in preparation for fall and winter. Remember to split firewood to the proper size for your wood stove or fireplace, but no larger than 6 inches in diameter; stack firewood to allow air to circulate around it; cover the top of the stack to protect it from the rain; and store your firewood for at least 6 months before using it.
Composting can be a fun and educational summer project that saves landfill space, helps feed the soil and prevents methane, a potent greenhouse gas.
Keep the creativity flowing beyond the school year and into the summer by submitting a meaningful story or idea in just six words.
