The forms of energy which can be replenished from natural sources such as the sun, wind, tide, geothermal heat are known as green energy or renewable sources of energy. The topic has gained a lot of momentum recently. From scientists to citizens and politicians to environmentalists, green energy has become the talk of the town. The topic of green energy is even mentioned in Mahée Ferlini’s Pinterest Board (Mahée is an Italian who has great interest in environmental issues). Here are a few things you need to know about green energy.
- According to a survey conducted recently, green energy accounts for about 21 percent of the world’s total energy consumption.
- Zero emission of green house gases and no adverse effect on the environment are the two most promising features of green energy.
- Unlike fossil fuels and petroleum, green energy is a never ending source of energy.
- Green energy is readily available even in the remote places of the earth.
- Solar power, wind energy and hydropower are some of the most prominent sources of green energy.
- USA and China are the two nations which have invested heavily for production of green energy.
- Green energy is expected to meet 40% of the total energy demand of the globe by 2040.
First of all, we need to know where earthquakes usually happen. Majority of earthquakes occur along the edge of the oceanic and continental plates. Oceanic plates are the pieces of the earth’s crust submerged in the ocean, while the rest are Continental plates.
The next thing we need to do is to learn what to do to survive during an earthquake. One theory proposed by Doug Copp, is the triangle of life. A controversial method which enables the person to quickly access a safe location when a collapsed object crushes a furniture. When the roof falls on an object, it creates a void which is supposedly a safe place to hide preferably in a foetal position.
The triangle of life theory is only applicable inside buildings filled with sturdy objects that can hold the weight of an entire floor. If an earthquake happens and you are in a city, and you are inside a vehicle, do not stop in areas that have any tall objects that will likely fall on you and your car. If you are outside a building and not in any vehicle, run to the centre of the street.
Another thing you could while inside a building is to take cover under a reliable object that won’t crushed easily, desk and tables are considered the best by experts like Red Cross and Fema. After taking cover under, cover your head and neck, hold the legs of the table or desk as firm as you can. Check this post How to Survive an Earthquake – 5 Useful Tips and know more about what to do to survive during an earthquake.
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
A typical person will lose minimally two to maximally four liters of water per day under ordinary conditions, and more in hot, dry, or cold weather. Four to six liters of water or other liquids are generally required each day in the wilderness to avoid dehydration and to keep the body functioning properly. The U.S. Army survival manual does not recommend that you drink water only when thirsty, as this leads to under hydrating. Instead, water should be drunk at regular intervals. Other groups recommend rationing water through "water discipline".
A lack of water causes dehydration, which may result in lethargy, headaches, dizziness, confusion, and eventually death. Even mild dehydration reduces endurance and impairs concentration, which is dangerous in a survival situation where clear thinking is essential. Dark yellow or brown urine is a diagnostic indicator of dehydration. To avoid dehydration, a high priority is typically assigned to locating a supply of drinking water and making provision to render that water as safe as possible.
Recent thinking is that boiling or commercial filters are significantly safer than use of chemicals, with the exception of chlorine dioxide. Anyway, if you read our ultimate family survival guide, it may be of great help in some cases.
If you're studying the art of landscaping then this is the article that you must read! The topic that I'm going to talk about today is spatial composition in landscaping.
When it comes to landscaping, many people only think about what plants and flowers to plant in their gardens. But landscaping is more complicated than that. It's not always about the plants and flowers in your garden. Sometimes it's about how your garden looks as a whole. Think of your landscape as a three-dimensional space with a floor, walls and a ceiling. And if you do it right, you can fully appreciate the art of landscaping. Try these tips for using plants, hardscapes and built structures to define your outdoor rooms.
Choose Your Floors
Depending on your needs, the "floors" of your outdoor spaces can range from soft surfaces like grass or mulch to hard surfaces like decking or concrete. For example, you can find some gardens with brick pavers which define the seating area, while a large expanse of grass creates a kid-friendly play area.
Find Your Style
Like you would for your home's interior, consider color, texture and pattern when choosing floors for your outdoor spaces. A unique swirl of small rocks within a pattern of larger stones creates an interesting focal point for this patio.
Plant Your Walls
Plants in various textures, shapes and sizes can create the "walls" of your outdoor space. An assortment of plants paired with a retaining wall of railroad ties makes this space feel intimate yet still open. Pea gravel acts as a comfortable carpet.
Build It Up
Built structures, such as fences, walls or arbors, can also act as the walls of your outdoor spaces. And it's also an easy to do landscaping privacy solution that you should consider. Nobody want their neighbors to observe their families activities right?
