There are at least seven global or widespread disasters that seem
 likely to occur at sometime in the future. A large asteroid hitting the
 earth is one of those seven. It is generally accepted by scientists 
that asteroids have struck the earth in the past causing widespread 
damage. It is believed that asteroids will continue to collide with the 
earth every now and then. Maybe every sixty million years a big one 
comes along that is large enough to have a global effect on survival of 
earth's living things. The chances of such an event happening in a 
particular person's lifetime are tiny. But that tiny chance is there.
It
 is unpleasant to consider such terrible things. But the best attitude, 
it seems to me, is to ignore, to a very large extent, the unpleasant 
feelings that the topic causes. That allows a person to consider what 
might be done to increase the chances of surviving a disaster. No way 
can a person be fully prepared. And since we cannot know just what is 
going to take place, it may be an exercise in futility. But you never 
know, simple basic preparations could bring you through some calamity.
And
 why not take the attitude that your efforts and interest in such 
preparation is something to feel good about. Those efforts can be fun 
and interesting. The topic certainly grabs my attention better than a 
Hollywood movie. By doing what I can to become prepared, I am doing 
something that could dramatically make my life much more pleasant should
 I be involved in a catastrophe. Disaster preparedness is an interesting
 and enjoyable hobby that could pay off big-time. Knowing that all the 
benefits of modern life are not necessarily a given, is a reason for 
enjoying them more.
The seven possible widespread or global disasters:
1).
 Very large volcanic eruptions. Hugh volumes of gas and dust could 
spread around the globe. There is some evidence that these have occurred
 before. Doesn't that mean that it could happen again?
2). An 
epidemic. There was the flu epidemic of 1918 that killed 30 million 
people worldwide. There was the plague that killed about one fourth of 
Europe's population in the Dark Ages. Viruses and germs are known to 
mutate and change. They may become resistant to vaccines and 
medications, become more deadly, and become more contagious. Viruses and
 other pathogens cold mutate into virulent forms that could spread 
rapidly around the world by people using air travel.
3). Crop failures due to plant diseases, climate change, or ozone depletion.
4).
 Climate changes including global warming and the effects that might 
come with it such as extreme heat, drought, and severe storms.
5). Nuclear war.
6).
 Terrorist act which could bring about widespread effects. If, for 
instance, a nuclear device was detonated in Washington, D.C. and another
 wiped out Wall Street, the effects could be unpredictable and could 
include economic depression, anarchy, shortages of consumer goods, and 
war.
7). Something unexpected. A disaster could be caused by a 
completely unknown event. It is unreasonable to think we are smart 
enough to be aware of all threats that could bring catastrophe.
There
 are many other plausible scenarios for widespread catastrophes. These 
include such things as a large solar flare that shoots out radiation and
 charged particles toward the earth; an object such as a black hole 
passing close to the earth; and a technology accident such as a 
genetically modified organism being released into the environment.
In
 recent years vast quantities of methane gas have been discovered on the
 sea floor where the water is very deep and in places where the water is
 very cold. It is believed that global warming or earthquakes could 
cause the methane to be released perhaps suddenly and in massive 
quantities. Methane is explosive and could displace oxygen causing 
suffocation.
Below are some things you can do to be better prepared for emergencies.
Store
 food and water: About a gallon of water a day per person is a 
reasonable goal. How many days worth is anybody's guess - you have to 
use your own judgment about what is practical for you. Know where to get
 water if your standby supply runs out. Water of unknown purity should 
be boiled at least 3 minutes to kill any pathogens. If boiling is not 
possible add 16 drops or 1/4 teaspoon of household bleach per gallon and
 let stand at least 30 minutes. Smell the water. If it does not have a 
slight bleach odor, repeat the process. Use bleach that contains nothing
 else other than water and 5.25 percent sodium hypochlorite. Bleach is 
most effective for killing bacteria but is not effective against 
parasitic organisms.
Choose long storage food such as canned 
goods, dry food such as nuts, seeds, beans, and grain products in 
plastic or glass containers. Most dried beans will need to be soaked and
 cooked before eating. Examples of dried beans that can be eaten after 
soaking and without cooking include split peas, mung beans, lentils and 
black-eyed peas. Wheat and corn can also be soaked and eaten without 
cooking. Peanut butter and vegetable oil are good choices because they 
are calorie rich, long keeping and require no preparation. Canned meat 
provides protein and requires no cooking. A multi vitamin will help with
 adequate vitamin requirements.
Keeping warm: The colder the 
climate where you live, the more important this is if the electrical 
power fails or you are forced to leave your home. Have enough heavy 
clothing and blankets in your home to keep you warm. Have ready to go to
 put in your car such as in a garbage bag: at least two changes of 
clothing that will keep you warm, a sleeping bag or a couple of 
blankets, gloves, knit hat, and sturdy shoes.
First aid kit: The most important items may be soap for washing a wound, an antiseptic ointment, and bandaging.
Tools
 and supplies for short-term emergencies: Flashlight and batteries, 
candles, matches, can opener, soap, battery-powered radio and batteries,
 face mask for filtering the air you breath,
Tools and supplies 
for long term emergencies: all of the items above for short-term 
emergencies plus the food items listed above plus: long lasting led 
flashlight, wind-up flashlight, wind-up radio, unscented 5.25 percent 
sodium hypochlorite bleach for purifying water, sturdy knife and 
sharpener, salt, grain grinder, food storage containers, shovel, 
blankets, rifle and ammunition.
Tools and supplies for your car: 
gallon of drinking water, blanket, extra clothes (sweatshirt, long 
underwear, boots, socks, gloves, hat), compass, rain gear, 
battery-powered radio and batteries, long storage and light-weight food,
 maps, siphon (20 feet plastic tubing, 1/2 inch diameter), gas can, 
wrenches, pliers, screwdrivers, portable light. Long-term and extras: 
bleach for purifying water, shorts or swimsuit, tube tent (or 10 by 10 
tarp, cord), ground moisture barrier, closed cell foam sleeping pad, 
sleeping bag, insect repellant, sunglasses, sunscreen, soap, knife, 
backpack, duct tape, cord (i.e., seine twine, parachute cord, masons' 
twine).
Have a short-term plan: Discuss with your family how 
everyone will get home if their usual transportation is not available. 
If the phone systems are operating, one person could remain at home to 
take and relay messages. Have a place in mind in case you need to 
relocate to a different geographic area. Plan how to get there and what 
you will take along. If you believe you are not enough prepared, decide 
how to become so.
Stay informed: Have at least a battery operated 
am/fm radio with extra batteries. A wind-up radio not requiring 
batteries could be used if the power is off for an extended period. 
Emergency alert radios might receive broadcasts in a long-term power 
failure where the backup generators for am/fm radio stations have run 
out of fuel.
If situations develop so that longer-term solutions 
are needed, you will need other strategies. You may have to hunt for and
 gather food from the wild. Very long-term collapse of the present 
supply chain would require that you become self-sufficient in mending 
and making your own clothing. You might have to construct a shelter 
using basic tools and basic materials. The scope of this article does 
not allow for discussions of what you would need to know to survive 
extended collapse of society into how it was a couple of hundred years 
ago.
