Drinking Water: Bottled or From the Tap?

If your family is like many in the United States, unloading the week’s groceries includes hauling a case or two of bottled water into your home. On your way to a soccer game or activity, it’s easy to grab a cold one right out of the fridge, right?

But all those plastic bottles use a lot of fossil fuels and pollute the environment. In fact, Americans buy more bottled water than any other nation in the world, adding 29 billion water bottles a year to the problem. In order to make all these bottles, manufactueres use 17 million barrels of crude oil. That’s enough oil to keep a million cars going for twelve months.

Imagine a water bottle filled a quarter of the way up with oil. That’s about how much oil was needed to produce the bottle.

So why don’t more people drink water straight from the kitchen faucet? Some people drink bottled water because they think it is better for them than water out of the tap, but that’s not true. In the United States, local governments make sure water from the faucet is safe. There is also growing concern that chemicals in the bottles themselves may leach into the water.

People love the convenience of bottled water. But maybe if they realized the problems it causes, they would try drinking from a glass at home or carrying water in a refillable steel container instead of plastic.

Plastic bottle recycling can help—instead of going out with the trash, plastic bottles can be turned into items like carpeting or cozy fleece clothing.

Unfortunately, for every six water bottles we use, only one makes it to the recycling bin. The rest are sent to landfills. Or, even worse, they end up as trash on the land and in rivers, lakes, and the ocean. Plastic bottles take many hundreds of years to disintegrate.

Water is good for you, so keep drinking it. But think about how often you use water bottles, and see if you can make a change.

Betty McLaughlin, who runs an organization called the Container Recycling Institute, says try using fewer bottles: “If you take one to school in your lunch, don’t throw it away—bring it home and refill it from the tap for the next day. Keep track of how many times you refill a bottle before you recycle it.”

And yes, you can make a difference. Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours.

Eat Your Leftovers

Even though most of our parents diligently drove home the virtues of clearing our plates and eating our vegetables (all of them), compostable waste such as yard trimmings and food scraps still make up 23 percent of the U.S. solid waste stream.

Meanwhile, huge plots of land and countless resources are devoted to producing the ingredients that go into our various meals and snacks. For example, we've got 255 million chickens busy providing for our nation's annual demand for eggs, and a geographic area the size of Wyoming growing our wheat. With that in mind, wasting food is about more than just wasting money—it's also about wasting all the land resources that produce it. That doesn't mean you should keep eating when you're already full. Just save the leftovers and have them later. After all, nothing is better than a cold slice of pizza in the morning.

Mondays Can Be Dangerous for Your Health
from National Goegraphic
The most common time for a heart attack to occur is Monday morning. The reason? Many workers have a significant increase in blood pressure when they go back to the office after the weekend. The stress of commuting could also be a factor.

About the Heart

The heart is the body's engine room, responsible for pumping life-sustaining blood via a 60,000-mile-long (97,000-kilometer-long) network of vessels. The organ works ceaselessly, beating 100,000 times a day, 40 million times a year—in total clocking up three billion heartbeats over an average lifetime. It keeps the body freshly supplied with oxygen and nutrients, while clearing away harmful waste matter.

The fetal heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, then a snake's, with three, before finally adopting the four-chambered structure of the human heart.

About the size of its owner's clenched fist, the organ sits in the middle of the chest, behind the breastbone and between the lungs, in a moistened chamber that is protected all round by the rib cage. It's made up of a special kind of muscle (cardiac muscle) that works involuntarily, so we don't have to think about it. The heart speeds up or slow downs automatically in response to nerve signals from the brain that tell it how much the body is being exerted. Normally the heart contracts and relaxes between 70 and 80 times per minute, each heartbeat filling the four chambers inside with a fresh round of blood.

These cavities form two separate pumps on each side of the heart, which are divided by a wall of muscle called the septum. The upper chamber on each side is called the atrium. This is connected via a sealing valve to the larger, more powerful lower chamber, or ventricle. The left ventricle pumps most forcefully, which is why a person's heartbeat is felt more on the left side of the chest.

When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart. These vessels are the two main arteries. One of them, the pulmonary artery, takes blood to the lungs to receive oxygen. The other, the aorta, transports freshly oxygenated blood to the rest of the body. The vessels that bring blood to the heart are the veins. The two main veins that connect to the heart are called the vena cava.

Blood Delivery

Since the heart lies at the center of the blood delivery system, it is also central to life. Blood both supplies oxygen from the lungs to the other organs and tissues and removes carbon dioxide to the lungs, where the gas is breathed out. Blood also distributes nourishment from the digestive system and hormones from glands. Likewise our immune system cells travel in the bloodstream, seeking out infection, and blood takes the body's waste products to the kidneys and liver to be sorted out and trashed.

Given the heart's many essential functions, it seems wise to take care of it. Yet heart disease has risen steadily over the last century, especially in industrialized countries, due largely to changes in diet and lifestyle. It has become the leading cause of death for both men and women in the United States, claiming almost 700,000 lives a year, or 29 percent of the annual total. Worldwide, 7.2 million people die from heart disease every year.
