Bears live primarily in the forest and they have a remarkable way of adapting to people moving in to their territory. Black bears eat berries, nuts, tubers, roots, honey, worms, buds, leaves, fruit, twigs, grubs, fish, insects, and small mammals. In the spring, black bears even eat the inside layer of young trees. They must eat between 11 and 18 pounds of food each day to stay healthy. Black bears hibernate during the winter months.
Water should be boiled for at least 3 to 5 minutes to sanitize it. Some agencies recommend boiling for 10 minutes just to be safe. If you live at high altitudes, add a minute for every 1000 feet above sea level.
According to the Washington State Department of Health and the United States Environmental Protection Agency, you should bring the water to boil and keep it rolling for one minute to purify it.At altitudes above one mile, 2,000 meters, you should increase the rolling time to three minutes.ou should filter the water as many times as necessary until it becomes clear. However, remember that you will still need to boil it before it is safe to drink as filtering does not remove or kill microscopic pathogens the water might contain.
