  • Tropical Rainforest Fast Facts Print Fast Facts Description Tropical rainforests are a type of wet, warm, humid forest. Tropical rainforests have the greatest biodiversity of any other ecosystem on earth. Some scientists believe they house more than half of all living species on earth. 90% of the species found in the tropical rainforest live in the canopy, high above the ground. Location Tropical rainforests are located in the tropics, the area around the warm equator. They are found in areas of Africa, Asia, Australia, and South and Central America. Climate The climate of tropical rainforests is warm and humid with almost continual rain. Most rainforests receive 200-1000 cm of rain a year and have temperatures that rarely drop below 22° C. Issues Tropical rainforests are quickly disappearing as a result of logging and clearing for timber, livestock grazing, plantations, and the harvest of other natural resources. 31 million hectares of tropical rainforest are destroyed each year.  That is an area larger than Poland. Status All tropical rainforests are in great danger of being destroyed. They once covered 14% of the earth’s land surface but now only cover 6%. Some scientists believe that, at the current rate of destruction, the remaining forests could be destroyed in less than 40 years. The state of tropical rainforests should be a priority for all countries and cultures since they provide and regulate the majority of the earth’s clean air and water. ©GLOBIO.org

Egyptian Giant Solpugids (Camel Spiders), Egyptian Giant Solpugid (Camel Spider) Pictur... - 0 views

  • Camel spiders became an Internet sensation during the Iraq war of 2003, when rumors of their bloodthirsty nature began to circulate online. Many tales were accompanied with photos purporting to show spiders half the size of a human. For many years, Middle Eastern rumors have painted camel spiders as large, venomous predators, as fast as a running human, with a voracious appetite for large mammals. The myths are untrue. These creatures do not actually eat camels' stomachs or sleeping soldiers, and they are not so large—but the real camel spider is still an amazing predator. The camel spider's history of misinformation begins with a misidentification. Camel spiders are not even spiders. Like spiders, they are members of the class Arachnida, but they are actually solpugids. Camel spiders, also called wind scorpions and Egyptian giant solpugids (SAHL-pyoo-jids), are only about 6 inches (15 centimeters) long. Photos that purport to show creatures six times that size have misleading perspective—the spider is invariably placed in the foreground where the lens makes it appear much bigger than its actual size. True, they are fast, but only compared to other arachnids. Their top speed is estimated at 10 miles (16 kilometers) per hour. Camel spiders are not deadly to humans (though their bite is painful), but they are vicious predators that can visit death upon insects, rodents, lizards, and small birds. These hardy desert dwellers boast large, powerful jaws, which can be up to one-third of their body length. They use them to seize their victims and turn them to pulp with a chopping or sawing motion. Camel spiders are not venomous, but they do utilize digestive fluids to liquefy their victims' flesh, making it easy to suck the remains into their stomachs.

Tropical Rainforest- Trivia & Facts on Saving - 0 views

  • Today, we know that the soil of the tropical rainforests is thin and very low in nutrients. Decomposers like leaf-cutter ants, termites, bacteria, and fungi quickly turn falling leaves and dead organisms into nutrients. Plants take up these nutrients the moment they are available, so they don’t get a chance to enrich the soil. Keeping Tropical Rainforests Healthy Conservation of tropical rainforests should be easy. They have survived for millions of years. The trick to keeping them healthy is to not take too much too fast. This gives the rainforests time to recover from human activities like logging. But many countries that have tropical rainforests are poor. They can make money by cutting down and developing the rainforests. But uncontrolled development results in deforestation

      About the rainforest cycle. (First Paragraph)
  • Rainforests have 170,000 of the world's 400,000 known plant species. The United States has 81 species of frogs, while Madagascar (which is smaller than Texas) may have 300 species. Europe has 321 butterfly species, while Manu National Park in the tropical rainforest of Peru has 1,300 species! The world’s only species of flying snake and lizard live in the Borneo rainforest. The largest catfish in the world lives in a tropical rainforest river in Vietnam. It weighs over 300 kg. About one-quarter of all the medicines we use come from rainforest plants. Curare comes from a tropical vine. It is used as an anesthetic and to relax muscles during heart surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants might be potential cures for cancer.
  • Some traditional rainforest cultures still live in the forests. They travel as a group to collect and hunt food. As rainforests are destroyed, so are the homes of these interesting and amazing people.

  • More than half the species on Earth are found in tropical rainforests. Many species living in these forests have never before been seen or studied by scientists. Most of these unknown species are insects, like moths.
  • Tropical rainforests are wet nearly all the time. They get lots of rain all year long, but they also help make rain through evaporation. Tropical rainforests help regulate weather all over the world.
  • Tropical rainforests are found in a narrow region around the equator that is known as the tropics. The climate is rainy and the temperatures are warm and nearly the same every day. The sun and the rain combine to create an environment that is very humid. This climate is ideal for the growth of many kinds of green plants.
  • Many different frog species live in the canopy of the rainforest. Most spend their entire lives in the canopy. They lay their eggs in little pools of water held in leaves instead of in ponds or streams.
  • Tropical rainforest plants have many adaptations for living in the forest. Some collect all their water from the air. For this reason, many of them have very large leaves. Others have flexible stems that allow them to bend and follow the sunlight so they can carry out photosynthesis all day.
  • which is part of a conservation effort known as ecotourism. People also are trying to help wildlife survive by creating protected areas and rehabilitation centers.
  • Decomposers like leaf-cutter ants, termites, bacteria, and fungi live on the forest floor. These decomposers quickly turn fallen leaves and dead organisms into nutrients. This creates food for trees and other plants and animals.

FastFacts What's Made From Trees? - 0 views

  • What's Made From Trees? It's no wonder people have used wood products for centuries. Wood is durable, renewable, recyclable, biodegradable, energy efficient and environmentally friendly. What would your life be like without wood? Things made from trees touch our lives every day. More than 5,000 products come from trees. And there are many uses for wood that may surprise you. Trees not only provide wood and paper, but other less obvious forest products such as chemicals and other materials that are impor- tant ingredients in plastic filler, varnishes, tooth- paste, shoe polish, foam rubber and much, much more. Tree bark is used for mulches, soil conditioners, medicines and cosmetics. Once a log reaches a mill, there is virtually no waste. The entire log is used to produce either lumber, paper, particleboard products or energy. Nationally, forest product companies are one of the most efficient of all manufacturing industries because they use sawdust and other wood waste to furnish up to 75% of their energy needs.   Idaho Forest Products Commission©2005 All rights reserved.

  • o study the behavior of animals so large and potentially dangerous can be difficult. Too close and you could get killed. Too far away and you can’t learn anything. So what to do?  Technology can help. First, the rhino can be carefully shot with a small dart containing a sleeping drug.  A few minutes later, after the rhino falls asleep, scientists can move in and attach a small radio transmitter. The transmitter will send back information about the rhino’s movements after it wakes up. Using computers and GPS signals, scientists can track a rhino in thick bush, over hilly country and even at night.  Over time, the rhino’s travels will build a map telling scientists where it wanders in the habitat—its territory.

Microfinance - Wikipedia, the free encyclopedia - 0 views

  • Microfinance is the provision of financial services to low-income clients, including consumers and the self-employed, who traditionally lack access to banking and related services. More broadly, it is a movement whose object is "a world in which as many poor and near-poor households as possible have permanent access to an appropriate range of high quality financial services, including not just credit but also savings, insurance, and fund transfers."[1] Those who promote microfinance generally believe that such access will help poor people out of poverty
    • Gurupranav G
       
      t definition on microfinance and how it helps the needy
  • Traditionally, banks have not provided financial services, such as loans, to clients with little or no cash income. Banks incur substantial costs to manage a client account, regardless of how small the sums of money involved. For example, the total profit for a bank from delivering 100 loans worth $1,000 each will not differ greatly from the revenue that results from delivering one loan of $100,000. But the fixed cost of processing loans of any size is considerable as assessment of potential borrowers, their repayment prospects and security; administration of outstanding loans, collecting from delinquent borrowers, etc., has to be done in all cases. There is a break-even point in providing loans or deposits below which banks lose money on each transaction they make. Poor people usually fall below that breakeven point. In addition, most poor people have few assets that can be secured by a bank as collateral. As documented extensively by Hernando de Soto and others, even if they happen to own land in the developing world, they may not have effective title to it.[2] This means that the bank will have little recourse against defaulting borrowers. Seen from a broader perspective, the development of a healthy national financial system has long been viewed as a catalyst for the broader goal of national economic development (see for example Alexander Gerschenkron, Paul Rosenstein-Rodan, Joseph Schumpeter, Anne Krueger ). However, the efforts of national planners and experts to develop financial services for most people have often failed in developing countries, for reasons summarized well by Adams, Graham & Von Pischke in their classic analysis 'Undermining Rural Development with Cheap Credit'.[3] Because of these difficulties, when poor people borrow they often rely on relatives or a local moneylender, whose interest rates can be very high. An analysis of 28 studies of informal moneylending rates in 14 countries in Asia, Latin America and Africa concluded that 76% of moneylender rates exceed 10% per month, including 22% that exceeded 100% per month. Moneylenders usually charge higher rates to poorer borrowers than to less poor ones.[4] While moneylenders are often demonized and accused of usury, their services are convenient and fast, and they can be very flexible when borrowers run into problems. Hopes of quickly putting them out of business have proven unrealistic, even in places where microfinance institutions are active.[citation needed] Over the past centuries practical visionaries, from the Franciscan monks who founded the community-oriented pawnshops of the 15th century, to the founders of the European credit union movement in the 19th century (such as Friedrich Wilhelm Raiffeisen) and the founders of the microcredit movement in the 1970s (such as Muhammad Yunus) have tested practices and built institutions designed to bring the kinds of opportunities and risk-management tools that financial services can provide to the doorsteps of poor people.[5] While the success of the Grameen Bank (which now serves over 7 million poor Bangladeshi women) has inspired the world, it has proved difficult to replicate this success. In nations with lower population densities, meeting the operating costs of a retail branch by serving nearby customers has proven considerably more challenging. Hans Dieter Seibel, board member of the European Microfinance Platform, is in favour of the group model. This particular model (used by many Microfinance institutions) makes financial sense, he says, because it reduces transaction costs. Microfinance programmes also need to be based on local funds. Local Roots Although much progress has been made, the problem has not been solved yet, and the overwhelming majority of people who earn less than $1 a day, especially in the rural areas, continue to have no practical access to formal sector finance. Microfinance has been growing rapidly with $25 billion currently at work in microfinance loans.[6] It is estimated that the industry needs $250 billion to get capital to all the poor people who need it.[6] The industry has been growing rapidly, and concerns have arisen that the rate of capital flowing into microfinance is a potential risk unless managed well.[7]

Hans Rosling | Profile on TED.com - 0 views

  • Even the most worldly and well-traveled among us will have their perspectives shifted by Hans Rosling. A professor of global health at Sweden's Karolinska Institute, his current work focuses on dispelling common myths about the so-called developing world, which (he points out) is no longer worlds away from the west. In fact, most of the third world is on the same trajectory toward health and prosperity, and many countries are moving twice as fast as the west did.What sets Rosling apart isn't just his apt observations of broad social and economic trends, but the stunning way he presents them. Guaranteed: You've never seen data presented like this. By any logic, a presentation that tracks global health and poverty trends should be, in a word: boring. But in Rosling's hands, data sings. Trends come to life. And the big picture — usually hazy at best — snaps into sharp focus.
