What is an endangered species?

Endangered species are those considered to be at risk of extinction, meaning that there are so few left of their kind that they could disappear from the planet altogether. Endangered species are threatened by factors such as habitat loss, hunting, disease and climate change, and usually, endangered species, have a declining population or a very limited range.

The current rate of extinction is thought to be far greater than the expected natural rate, with many species going extinct before they have even been discovered. Shockingly, current estimates suggest that a third of the world’s amphibians, a quarter of all mammals and one in eight birds are endangered.

Endangered species usually have a small or declining population size or a very limited range, meaning factors such as habitat loss, hunting, disease or climate change could cause them to disappear completely within our lifetimes.

The alarming rate at which species are disappearing  is something which should be a cause for concern for us all. Not only do they add beauty and wonder to the natural world, they are also of great global economic importance. A great diversity of species maintains the ecosystems essential to our existence by helping to regulate our climate and by providing:

• clean air and water

• food

• medicines

• building and clothing materials

• fertile soils

How can you help?

As  well as supporting conservation organisations there are some simple steps that everybody can take to help protect the natural world and the species in it. Here are some ideas:

• Recycle – Help protect the rainforests - recycling one tonne of paper can save 17 trees and preserve the habitat of a whole host of endangered species.

• Use less energy – An old tip but a good one, you can save yourself money and help the environment too. For example, energy saving light bulbs use 80 percent less energy than a standard bulb, yet produce the same amount of light.

• Choose sustainable products – Make sure that all the products you buy are sustainably sourced, from food and paper to timber.

• Make your voice heard – Petition for change! Many campaigns to help wildlife are underway but they need your support.

Arabic Tigers

 

 

For Arabic Tigers animals inhabiting the mountains high, contrary to what the public think they are animals of the desert dweller and fled the areas endemic States, are mainly located in the Jabal Samhan in the Dhofar region of Oman, Baha, Asir mountain chains running in Saudi Arabia, Arabian Leopard features day and night activity, but remains wary of human presence, These animals do not meet other isolationist Tigers only in mating period which lasts for approximately 5 days, during which altzwag several times. After a pregnancy lasting between 98 to 100 days, giving birth to female puppy four result in one of the caves or rock crevices. The Cubs are blind at birth,

 And open their eyes after nine to ten days, during these first weeks the mother move the Cubs from den to another several times to reduce the chances of finding other predators. Up the reconstruction of tigers in the wild is between 10 to 15 years, whereas reconstruction in zoos until 52 years.

The Tigers are Arabic light dramatically as yellowish gold color which normally exists between patches over most of body remaining breeds do not exist when this strain but along, and then fades to a pale yellow or white on the rest of the body. Featuring color blue eyes unlike the African counterparts.

The female weighs 20 kilograms (45 pounds), while the male weighs approximately 30 kg (65 lbs). In comparison, South African Tiger can weight ranges between 50 to 70 kilograms, so the Tigers could be considered as Arabic is smaller than the rest of the African and Asian Tiger breeds. Similar to the male with the female, But the males are larger than females, and are distinguished by the presence of the scrotum in males, and is clearly characterized by long tails Arabic Tigers, which used in balance while climbing

Endangered Animals

One of the rarest animals in the Sahara Desert is the Addax, also known as the white antelope or screwhorn antelope. It’s a rather unique creature whose coat actually changes color depending on the season. Due to its slow speed, however, it is a welcome meal for predators and an easy target for hunters

The mountain gorilla is primarily found in various regions all across Africa namely Uganda, Rwanda, and Virunga. They have thicker and longer fur, which makes them easily adaptable to cold environments. Aside from poaching, their population of 880 has decreased due to traps, kidnapping, loss of habitat, interaction with tourists, being killed for meat, and even lack of food.

Although the rhinoceros is considered to be one of the biggest mammals on
 the planet, this specific breed is actually the smallest of its kind. Their exact population is unknown but researchers are projecting that there may be 275 of them left in the wild.

The Arakan forest turtle is so rare that it can only be found in the Arakan hills of western Myanmar. Many believed that it went extinct in 1908 until it was rediscovered in 1994 although it has been determined that there are less than a hundred left in the wild.

The Siamese crocodile is native to parts of Southeast Asia and presently there are less than 70 left in the wild. Their survival has been compromised by people taking lands for farming, which affected the crocodiles due to the increase of cattle, use of pesticides, and chemical fertilizers that corrupted the clean water.

The brown spider monkey received its name due to its long limbs, which help it to swing and climb on trees. Its tail is also flexible enough that it is considered more of a limb due to its precision and usability when being used to hang on branches. The population of 60 has been the result of relentless hunting and wild animal trades, which usually occur in northern Colombia and northwest Venezuela

Dinosaurs: a very large animals that lived before the birth of man on Earth and lived for a 160 million years as scientists, were very large animals, including what is called live fire from his mouth. Vanished dinosaurs of all kinds, about 65 million years ago, scientists were unable to determine the cause of extinction, but the most likely cause was a collision with another asteroid planet, which led to the death of all the dinosaurs of all kinds, and was likely another team of scientists, the extinction of the dinosaurs to the occurrence of earthquakes and volcanoes continued for nearly a million and a half years on Earth as a result of climate change, which adzei to the end of life on Earth for all living organisms. Scientists called the Cretaceous extinctions, scientists found that there are some organisms that survived this extinction, scientists have outweighed the small creeping animals are spared, since their small size commensurate with any climatic envelope to live, while big and bulky is extinct, It has survived nearly more than 80 turtles and reptiles and small lizards managed to escape. In modern times the scientists found bones belonging to a dinosaur in the San Juan basin, and this made scientists before the first options is the possibility that some types of dinosaurs lived for 5000 years after the extinction, or that these bones belonged to a dinosaur before extinction, but the stronger weighting is that some dinosaurs were able to escape after the extinction. The first theory scholars tended to cause extinction is continental drift: the scientists proved that the Earth was a single large continent called Pangea, and then updated several divisions on the continent to consist of seven continents, when continental drift became continents approaching to the North and South poles, which led to the escape of dinosaurs from North and South toward the equator, warm areas more suitable for living dinosaurs from the polar regions, but this error occurs the theory that continental drift was not The reason that dinosaurs moved towards the equator, so life continued, and that extinction came after continental drift. Theory 2: the spread of poisonous plants in the late Cretaceous period, and that the dinosaurs suffered poisoning as a result of ingesting these plants leading to extinction. The third theory: extinction was an epidemic caused the death of all the dinosaurs in the Cretaceous, but the epidemic cannot be long kind of dinosaurs at the expense of another. Fourth theory: was that dinosaurs had begun to extinction as a result of collision with another asteroid planet, was partial and gradual extinction, but with climate change began and volcanoes in Western India, which led to the end of life for rodents. Differences remained among scientists for the extinction of dinosaurs, but remained most views combined on volcanoes that hit Earth, and earth asteroid collision last.

ِAurora

An aurora is a flickering light mostly caused by the sun's radiation, usually found near the poles. They are red, green and occasionally blue, and can sometimes resemble fire. In fact, the Roman Emperor Tiberius thought a city was on fire, so he sent firefighters to that city. The city on fire was actually a city against a backdrop of a red aurora.

An aurora can happen in the Arctic, around the North Pole (Aurora borealis - Dawn of the North - there it is also called the Northern Lights) or in the Antarctic around the South Pole (Aurora australis - Dawn of the South). An aurora can often be seen from long distances and stretching in the sky many hundreds of kilometers or miles.

Auroras can only be seen at night because their light is not as strong as the light of day. For instance, faint stars can be seen through the aurora. However they do happen during the day as well.

Mangoes are one of the most delicious and nutrient-dense fruits, and are known worldwide as the king of fruit. Mango is a tropical fruit that comes in as many as 1,000 varieties. Native to southern and southeast Asia, the fruit is now is also grown in Central and South America, Africa and the Arabian peninsula.

Mangoes are seasonal fruits, with the fresh mango fruit season beginning in May. Mangoes are usually harvested while they are green but perfectly mature. Unripe mangoes are extremely sour.

One mango contains about 3 grams of dietary fiber. Fiber lowers cholesterol and promotes healthful digestion. Mangoes are high in vitamin C, with one mango containing 96 percent of the recommended daily intake of vitamin C. Vitamin C is well known as an immune-system booster, offers protection from heart and eye disease and boosts skin health. The vitamin E and beta carotene in mangoes act as powerful antioxidants that help the body fight the effects of free radicals. Research suggests that eating a diet rich in foods high in antioxidants reduces the risk of developing certain types of cancers and cardiovascular disease. Mangoes are also rich in vitamin B6, iron, potassium and magnesium.

The nutritional value of mango fruit per 100 g: 17 g carbohydrates, 70 calories, 0.5 g protein and 0.27 g fat.
