Deserts are defined by how much rain they get. Most deserts, like the Sonoran in North America and Sahara in Africa, are hot. They receive less than 25cm of rain each year. The South and North Poles are also deserts but very cold.

Rainforests are disappearing very quickly. The good news is that there are a lot of people who want to save rainforests. The bad news is saving rainforests is not going to be easy. It will take the efforts of many people working together in order to ensure rainforests and their wildlife will survive for your children to appreciate and enjoy.

Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment Establish parks to protect rainforests and wildlife Support companies that operate in ways that minimize damage to the environment

A Food Pyramid in the Hot Desert Biome      Here we see a food pyramid that shows how the Kilocalories pass up the food chain.      The first trophic level is occupied by the primary producers, which are the plants.  Plants make food through photosynthesis. The limiting factor for these plants is the shortage of water, so they produce fewer than 200 Kilocalories of food for the animals for each square meter each year.     The primary consumers, who eat the plants, occupy the second trophic level. These animals have very little to eat, and are small. Many are insects, or reptiles, who are cold blooded and who use less energy to maintain their bodies than mammals and birds do. As food for predators, they provide about 20 Kilocalories per square meter per year for predators.      The predators are the secondary consumers. They occupy the third trophic level. Again we see cold-blooded animals, such as snakes, insect-eating lizards, and tarantualas. Only about 2 Kilocalories per square meter per year are stored in their bodies. In the harsher desert environments, they are the top predators.     In areas where deserts get more rain, more plant material is produced and a few tertiary consumers may be able to survive. They form a fourth trophic level.      This diagram shows the energy available at each trophic level in the hot desert biome. These numbers tell about the numbers of Kilocalories per square meter per year.  Cold Desert Energy Pyramid  Introduction to Desert Biomes  Return to Introduction to Biomes © Elizabeth Anne Viau, 1999.

The Harpy Eagle (Harpia harpyja) is one of the world's largest birds of prey, reaching over three feet from head to tail. This awesome predator is a powerful flyer, able to pluck a sloth or monkey off a tree branch. It gets its name from a mythical Greek demon that preyed on people

Respecting and ExtendingOur Wood Resource Today's near-zero-waste sawmills use computers and sophisticated equipment such as laser-guided saws to get the most lumber out of each log. In fact, today's mill recover about twice as much lumber from each log as did mills at the turn of the century. The wood fiber that is not usable as lumber is recovered and processed into other valuable products. These "by-products" of lumber manufacturing can become particleboard , oriented strandboard paneling, or other engineered-wood products. Byproducts are also used to fuel cogeneration plants which produce electricity for the sawmills. And wood fiber also is used to make such products as plastic filler, shoe polish, toothpaste, varnish, foam rubber, and much more!

Sahara Desert Plants The Sahara Desert is often described as a bleak and barren plain. In truth, it is very beautiful and full of different Sahara Desert plants. Sahara Desert Plants Among desert areas throughout the Earth, there are two types. The cold type of desert, which is often found in Arctic regions, is an area that gets very little precipitation. The cold desert can be covered in snow, however, and the temperatures here are chilly and unsuitable for sustaining many life forms. The other type of desert is known as the hot desert, and this is what people usually think of when they picture a desert area. This type of desert is extremely warm and dry, with temperatures reaching unbearable levels, and little to no rain to sustain those who live here. The biggest of the hot deserts is the Sahara Desert, located in Africa. Although this desert is not the most hospitable place for organisms to take up residence, the Sahara Desert plants defy the odds and thrive here.

Most nonhuman primates live in tropical and subtropical areas of the new world and old world. Most primates live an arboreal lifestyle, that is, they travel, eat, and sleep in the tops of trees. Even the larger apes, like chimpanzees and orangutans, usually sleep in leafy nests they make in trees. The most notable exceptions to this behavior are gorillas and humans. Both are ground dwellers.

As primates evolved over the past 50-60 million years, two important things happened. 1) Their faces flattened and the eyes moved to the front of the head, giving them binocular vision. 2) They developed hands with separate fingers and opposable thumbs. This allowed them to grasp and hold on to branches and other objects.

All Grown Up Male orangutans are large apes. They are generally more than twice the size of females. Males may weigh around 90 kg. Females rarely reach 40 kg. ©G.Ellis/GLOBIO.org Around the age of

Macaws are herbivores. They eat primarily seeds, nuts, and fruit. Using their impressive beaks, they have no problem opening even the toughest seed.

First they scratch a thin line with their beak’s sharp point, and then they shear the seed open. But inside some of those seeds are poisonous chemicals. How can macaws eat the seeds without getting sick or dying? They visit clay licks—the rainforest’s natural “drugstores.”

The Amazon rainforest has more than 100 of these special clay- and mineral-rich areas along riverbanks.

If It's Been Around So Long, Why Have I never Heard Of It Before Now? I guess there are still a lot of secrets in the South American Rainforests. The recent explosion in the popularity of Jagua body art just goes to show that there are many possibilities still out there that the outside world has not even noticed. More importantly it goes to show that local traditional knowledge is incredibly important to the whole world, not just the local people of the Rainforest. So every effort should be made to help preserve it.

Where Can I Get Hold Of Some Jagua Then? Well you could take a trip out to the rainforests and search it out yourself. But if your going to paint from an unripe fruit, you only have a short time to do it, before the stain stops working. But recently Jagua Body Art products like Jagua Paint and Jagua Gel have been made readily available to you so you can create your own jagua tattoos whenever you like.

Since just 1950, the world's population has more than doubled to more than 6 billion people, with the fastest population growth being in the tropics.

Today, more than 3 billion people live in the tropics alone, more than lived in the entire world in 1950.

Annual world consumption of tropical hardwoods is now more than 250 million cubic meters, or over 100 billion board feet, per year.

Eaten Any Wood Today? You may have! And you probably brushed your teeth with it. Chances are you even dressed with wood. Skeptical? Don’t be. We’re all familiar with forest products like lumber, furniture, and paper. But few of us realize how many different things we regularly use that are manufactured from trees. In fact, more than 5,000 wood and paper products make our lives better each day. Here are just a few: Fruits and NutsFruit from trees such as apples and peaches, as well as nuts from trees such as walnuts, are all favorite products grown on trees. Bandage StripsTree gum, sap extracted from trees, makes the adhesive on bandage strips stick to your skin. Baseball BatsThe white ash tree is a hardwood that is used to make baseball bats—including, of course, Kentucky’s own Louisville Slugger! CandlesTree gum can be used to make candles. ClothingCellulose is used to produce rayon and acetate, which can be used to make a vast array of clothing such as ties, shirts, dresses, and suits. CombsWood pulp and cellulose can be used to make plastics for items such as hair combs. Cough SyrupCellulose products, used for their even-flowing consistency, often thicken cough syrups and other liquid oral medicines. CrackersNot only is the cracker box a product of trees, but the crackers themselves can be made using a high-purity cellulose. CrayonsGum extracted from trees can help make crayons. Eyeglass FramesCellulose wood fibers are dissolved and can then be formed into molded articles like eyeglass frames. Football HelmetsEthyl cellulose is responsible for making the hard, impact-resistant plastics found in football helmets. GumGum and synthesized essential oils from trees can be used to make chewing gum. Ice CreamIce cream can be made with cellulose, which comes from trees. LipstickCellulose can help give lipstick its easy-apply texture. MakeupMakeup sometimes gets its creamy texture from the tree derivative cellulose. Maple SyrupSap from trees is used to make syrup. Milk CartonsMilk cartons can be made from pulpwood. Nail PolishNail polish contains nitrocellulose to help make the polish glossy when it dries. NewspaperPulpwood is used to make newspaper, wrapping paper, book paper, and wallpaper. PaintMethylcellulose, a product made from cellulose, gives paints their thick consistency. Parmesan CheeseCellulose powder is sometimes used to help keep grated Parmesan cheese pieces from caking together. PencilsTree logs are used to make pencils. PerfumeTree bark is used to make “tall oil,” which cosmetic companies can use to make perfumes. Photo FilmLogs are reduced to pulp, and the pulp is processed to create cellulose acetate chemicals that can be used to make photographic film. ShampooMethylcellulose can be used to thicken shampoo and conditioner. Without it, they would just be soapy water! SpongesCellulose is broken down into chemicals that can be used to make sponges. TiresTree-produced chemicals can be used for making the synthetic rubber found in tires. Toilet PaperWood pulp makes paper products such as toilet tissue, paper towels, napkins, and facial tissue. ToothpasteCellulose can be used in toothpaste to give it a paste-like consistency.

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

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]

Bangladesh, April 25 -- Education provided by the primary schools of our country is the root of all education on which depends the future of our country. But the bleak position of most of our government primary schools weakens the contribution to building up the foundation of our children. Almost every year the government is recruiting the teachers in the primary school through a written test and a viva voce. But very often many applicants fail to get the required marks in the exam but they...

Afghan girls were not allowed to go to school. Girls also had to hide or get rid off their dolls because the Taliban opposed all images of people or animals, including photographs and posters. Boys and girls were not allowed to play together. Afghan children were also not allowed to watch television or listen to music. Luckily, times have changed and many dedicated people are working hard to improve the lives of children in Afghanistan.

What Can I Do? As an individual, many people feel that there is little they can do to stop a problem as big as tropical deforestation. This type of pessimist thinking needs to be stopped, replace pessimism with optimism and many solutions will arise! Recycling paper can slow rates of annual deforestation. The largest component of solid waste by weight in the US is paper and paperboard (EPA, 1998). Roughly 40% of municipal solid waste is paper; each year about 71.8 million tons are generated (EPA, 1998). From an environmental or economic standpoint, it makes sense to recycle; not only can money be saved, but also trees. Valuable landfill space is prolonged; for every ton of recycled paper, three cubic yards of landfill are saved (EPA, 1998). Purchase items that carry the Forest Stewardship Council (FSC) image (Figure 11). The FSC, founded in 1993, is an international, non-profit association, that issues certificates for well managed forests; economic, social, indigenous, and environmental interests are all taken into account. To be classified as a well managed forest, the forest's ecosystem can not damaged, only low volumes of trees are expelled, and impacts on plant and animal life are limited (Greenpeace, 2001B).

Over 2000 tropical plants have been identified as having anti-cancer properties (RIC, 2000B). One of these plants may lead to a breakthrough in the treatment of cancer. Over 25% of the world's modern drug originally came from rainforests (RIC, 2000B). Many contraceptives, stimulants, and tranquilizers commonly used today originated in tropical rainforests. In 1987, a tree compound that was 100% effective against the HIV-1 virus was found in a Malaysian gum tree (Rainforest Alliance, 1999). When research biologists were sent back to get more samples from the tree, it had already been cut down. Unfortunately, no tree found since has produced the same compound (Rainforest Alliance, 1999). If deforestation continues at current rate humankind may lose the cure to two of the world's most fatal diseases.
