The Global Water Crisis
Posted November 19th, 2007 by admin
Water is vital to the survival of all known life forms. Water crisis is the state of the world’s water resources in relation to human demand. Global scarcity of usable water and water pollution are the major aspects of water crisis. A lot of people around the world do not have access to clean potable water, and the numbers are growing.
Around the world, 1.1 billion people are living without clean drinking water; another 2.6 billion people do not have proper sanitation, this results to death all over e to water borne diseases.
We see water all around us, yes 71% of the Earth’s surface is covered with water, but we have to understand that only a percentage of that is fit for consumption. The large water composition of our planet doesn’t mean that we have an infinite supply of useable water. By simple observation, a huge portion of the Earth’s water is salty, or locked up in ice and glaciers.
The Earth although abundant with water has a limited supply of fresh water. Oceans may be deemed as available water but the energy needed to convert salt water to fresh water is restrictive, only a fraction of fresh water can be derived from desalination, although newer technology is helping reverse the ratio. Water which is fit for consumption constitutes only a small percentage of all the water resources, and the sad thing is that it is diminishing because of contamination and pollution.
Inadequate supply of safe water and lack of sanitation accounts for the rising number of child deaths because of diarrhea. Poor supply of water for sanitation results to deaths affecting children most especially in underdeveloped countries, such deaths are considered preventable if only we can find a way how to distribute clean water properly.
Vegetation and livestock are all dependent on freshwater resources. This is our major food source and if it is threatened, it will challenge our survival as well. Overdrafting of groundwater causes decrease in agricultural yields. Low agricultural yields and deaths in livestock are direct results of water pollution. Water pollution and overuse of underground water resources truly harms biodiversity causing imbalance in nature
Armed conflicts arise over meager water resources resulting in displaced community e to this conflict. Regional conflicts arise in roughly 260 different river systems around the world. Existing international rules grants water rights among countries but still conflicts e to regional tensions on water supply are becoming a fight for survival, and warfare is inevitable. It is not just the scarcity of water that is causing death but the conflict that goes with it.
The demand for fresh, safe water increases over the course of time. Everybody must take their part in conserving water. The global water crisis will never go away if we don’t take an active part in providing our very own share. Each of us must think twice every time we turn that faucet.

⑷ "如何在森林中生活"英语作文,60词
Have you ever been on a hike admiring the wild flowers, gazing up at the tips of the trees--and suddenly found yourself completely alone and lost? What would happen to you if you couldn't find your way back to safety? While being lost in the woods can be a frightening experience, surviving alone in the wild is generally a matter of common sense, patience, and wisely using the gifts that nature provides. If you want to know how to survive in the woods, just follow these steps.

Part 1 of 2: Preparing for the Woods
1
Do your research first. Don't just trek off into the wilderness; get a solid understanding of your surroundings first. Studying a map of the area where you're going -- and making sure to bring it with you -- will increase your chances of not getting lost tremendously. Ecate yourself about the flora and fauna of the area you are exploring. Knowledge of the local plants and animals can save your life.
Ad
One of the most accurate books about this subject is "Bushcraft - Outdoor Skills and Wilderness Survival" by Mors Kochanski.
2
Make sure you eat well before you leave and someone knows where you're going and how long you'll be gone. Don't make the mistake that James Franco makes in 127, the survival movie based on a true story -- make sure someone know exactly where you're going and when. That way someone will realize that you are missing, quickly alert rescuers, and be able to tell them where to start looking for you.
3
Bring survival gear. Basic survival tools such as a knife, a fire steel (metal match), some matches (in a waterproof canister), some cord (550 paracord is best), a whistle, a space blanket, a signaling mirror, water purifying tablets, and a compass can mean the difference between life and death. Even if you are only out on a day hike, be sure to bring the essentials.
Having all this equipment is nothing if you cannot use it properly. Make sure to practice many times in a safe environment before venturing into the wilderness.
Don't forget to bring a first aid kit. You should bring band aids, antiseptic, and tweezers for removing splinters that could get infected.
If you need any medication or injections, bring them along – even if you don’t plan to be gone for long enough to need them.
A compass could save your life, it is one of the most useful tools in the wilderness.
Before you leave, learn how to use a compass. If you have a map and can spot a few prominent landscapes, you can actually use the compass to triangulate your position and, from there, figure out where you need to go.
When choosing a space blanket (a light, thin sheet of extremely reflective Mylar), spend a little extra to buy a larger, more rable model. A space blanket can be used to block wind and water, wrapped around the body prevent/counteract hypothermia, or even placed behind you to reflect a fire’s heat onto your back, but none of this is useful of the blanket is too small or tears the moment you unwrap it.
4
Bring a means of communication. A cell phone with spare battery or a portable CB radio can be your best, quickest means of rescue if you are truly lost or injured. A cell signal may only be obtainable only from a hill or tree, but is better than nothing. Serious hikers may even consider investing in a personal locator beacon such as the SPOT Messenger for extended, precarious, or very remote, treks.
Ad
A SPOT Messenger is a satellite communication devices that allows you to contact emergency services, reach your own personal contacts for help ring non-emergencies, or even simply check in with your friends and family as you trek so that they know you’re alright. A service subscription is required and is not cheap.
Part 2 of 2: Surviving in the Woods
1
Don't panic if you’re lost. Panic is more dangerous than almost anything else, because it interferes with the operation of your single best, most useful and versatile survival tool: your mind. The moment you realize that you are lost, before you do anything else, stop. Take a deep breath and stay calm. Before you act, follow the tenets of the acronym STOP:
S = sit down
T = think
O = observe your surroundings
P = prepare for survival by gathering materials
2
Get oriented. Wherever you are will become your "point zero." Find a way to mark it using a spare piece of clothing, a pile of rocks, a sheet of paper, or anything else easily visible from a distance. Learn your basic directions -- the sun rises in the East and sets in the West. Use this to tell directions as on a compass (in a clockwise direction starting at the top 12:00) North, East, South, West.
For example, if it is late afternoon and the sun is on your right you must be facing South.
Learning how to spot the North Star at night in your backyard beforehand will also prove invaluable.
3
Stay in one place. This not only increases your chances of being found, but also reces the energy your body expends and the amount of water and food you will need. Hunker down and stay put. Chances are that someone will be looking for you, especially if you let someone know your plans. Also, if you're with someone else, do notseparate. Having strength in numbers will help you survive.
Also seeking nearby shade if it is hot out which greatly decreases your risk of dehydration and sunburn. Don't be tempted to remove clothing as this only increases these risks.
4
Build a fire. Build a good-sized fire with sufficient coals to stay hot for many hours, and make sure that you have plenty of extra dry wood. Start the fire before you think you need it, even if the weather is warm; fires are easier to make under easy conditions than in a panic as the sun sets – to say nothing of the fact that having a fire nearby will give you a sense of comfort and safety as you get your bearings.
A good rule of thumb is to gather wood until you think you have enough to last the night, then gather three more piles of the same size, after which you mighthave enough to get through the night.
You should have access to dry wood in the understory of the forest. You can also use bark or dried ng. If you build a fire that is hot enough, you can also burn green wood, brush, or tree boughs to make a signaling fire that creates a lot of smoke.
The best wood for maintaining a fire is dead wood that you pull off a standing tree. Regardless of what type of woods you are in, there will certainly be some dry wood available.
Remember that a small fire is easier to keep burning than a big fire, though, because it requires less fuel. Once you have sufficient embers, keep the fire to a manageable size so you don't spend too much time looking for fuel.
Don't build a fire in an area where it is unsafe to do so. Your fire should be well away from flammable trees and brush, preferably in a clearing. Be careful with your fire. While you want to feed it, you shouldn't overdo it. Consider the weather and other factors and remember, a forest fire is a lot harder to survive than just being lost!
5
Signal your location. Make noise by whistling, shouting, singing, or banging rocks together. If you can, mark your location in such a way that it's visible from the air. If you're in a mountain meadow, make three piles of dark leaves or branches in a triangle. In sandy areas, make a large triangle in the sand. Three of anything in the wilderness is a standard distress signal.
You can use the fire to send a distress signal. The universal distress signal is created by three fires in a straight line, or three fires that form a triangle.
You can also blow a whistle three times shoot three shots of a rifle in the air, if you have one, or shine a mirror that catches the light three times.
6
Scout your area. Though you shouldn't move around too much, you should explore your immediate surrounds to find anything useful. You could find things someone left there before, be it a tin can or small lighter, it can be helpful significantly. Be sure you can always find your way back to your "point zero" as you search for water, shelter, or your way home.
7
Find a good source of water. In a survival situation, you can last up to three days without water, but by the end of the second day you're not going to be in very good shape; find water before then. The best source of water is a spring, but the chances of finding them are slim. You should also look out for nearby birds, because they like to fly around fresh water. Drink your remaining water -- you should ration it, but not so much that you're thirsty right away.
A running stream is your next best bet; the movement of the water reces sediment. Be advised that drinking water from streams can lead to some sicknesses, but when you're in a life-or-death situation, the risk of illness is a secondary consideration and anything you may get can be treated when you return.
If there’s dew and you’re desperate, you can gather it in your clothes and then suck the moisture out of the fabric.
You may also be able to find water in the crevices of a rock.
8
Purify your water. A crude method of water purification is to take your handy pot and heat the water. For this to effectively kill bacteria, it must be at a rolling boil for at least three minutes.[1] You can also put (clear) water in a clear plastic bottle and set it in the sun for six hours to kill most of the organisms.[2]
However, if the water is so full of sediment that the sun can’t penetrate it, this method will not work. If you have any, add a pinch of salt to the water to try to bring the sediment to the bottom.

From ancient times, land, is a country and a nation depends on the survival of the source, as China's rapid economic development, land issues restricting China's economic development as a serious problem, thus, the land policy is a reasonable solution to our faces difficulties is very important.
