A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

   A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.

   P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.

   Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

   The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters are not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

   The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

   The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

Home security products give a homeowner peace of mind as well as the ability to protect loved ones and physical possessions around-the-clock.

_____

Having the right security products equipped in a home can get rid of home invasion, theft and injury. Home security products should be hidden somewhat and not out in the open for invaders to see. Products that protect one's home should also be linked to the local police department so that they can be notified in the event of an emergency or break-in.

_____

Security products are used for monitoring the home and the properties surrounding the home. Products are designed to warn the homeowner when invasion is taking place or someone is hidden around the property. Most systems are electronic or battery powered and some are linked with cables and satellites to keep a close watch on property.

_____

 There are four main kinds of home security products. The first kind is home entry and invasion protection--used for setting up a high tech alarm system. The second is window and door alarms, helpful in warning the homeowner as to who is coming in and out of the house and certain rooms in the home. The third is to keep the outside of the home protected by signaling. The fourth is a combination of security gates, cameras connected to a DVR, bars for windows and doors as well as sliding door lock.

_____ 

 One should consider the expense of equipping a complete security system. For most complete systems which include driveway alarms, cameras, and electronic keypads, many can cost from $100 to $10,000. The homeowner can equip individual security products based on the needs of the home and family to save money.

_____

Preventing invasion, theft and injury can save thousands of dollars if the home was broken into and items were stolen. Having home security products equipped can also reduce car and auto insurance moneys.
