Rain forests are disappearing at a drastic rate. Industry is usually at the root of this destruction of one of natures resources. Land is needed for highways, agriculture, livestock, or to expand a city. Other times the trees themselves are needed by lumber companies of countries that themselves lack to forests necessary to meet their countries demands such as Japan. Environmentalists are deplored by this destruction refuting that bio-diversity is being lost, an ancient way of life is being lost as "people of the forest" are being forced out of their homes, new diseases are being stirred up and that the earth is a living organism and man is behaving like a virus.
Some third world countries clear cut the land with a slash and burn technique to build roads or highways such as the massive Brazilian superhighway. This highway stretches to one end of Brazil to the other. However as with many of these roads it leads into the jungle and just ends. Billions and billions of trees and animals are killed for these roads to nowhere for the sake of progress.
Simple farmers have always cleared the land for their crops. This damage is only minute compared to that of what happens when large plantations are planted. Such companies as Coca-Cola clear hundreds of acres to grow orange crops. These oranges are then sent back to the United States to be used in Minute Maid orange juice. Coca-Cola isn't alone, Tropicana, Ocean Spray, and most concentrates contain rain forest oranges. The problem with using this soil for agriculture is that all the nutrients are depleted within one to two years and is dead from that time on. The land is dead for centuries to come.
Other times the land is needed for large herds if cattle. Without trees to protect the land from erosion from the cows, this land is trampled continuously with the cattle consuming all of the grasses as well. Once it rains the soil is further eroded away leaving the land barren and dead with more trees needed to be cut down so that the process could start all over again. The sad thing is that this is cone to cut livestock prices. Such restaurants as Burger king use rain forest beef since it is so cheap. Burger King is the better known of all rain forest beef users but not the only one.

Anatomy of the heart consists of the Atria, which is a collection of blood and not much pump force, Auricle which is attached to the atria to increase potential volume filling, Ventricles have thought myocardium and do the majority of pumping blood, Exterior is the coronary sulcus and the anterior and posterior sulci, the apex is inferior and only the larger left side, and then the base is the superior flattened top of the heart. As we know the heart does conduct electricity, the resting threshold of the heart is -90mV and has a fast and slow channel. Fast channels are transitory whereas slow channels are long lasting which allows for prolonged depolarization. The heart has different rates of depolarizations, it has a central node (SA) which “is the heart 's natural pacemaker”(Medicine Net) which has a BPM of

Deforestation is defined as the clearing of trees, and the absence of a forest. What most people seem to turn a blind eye to the fact that we need these trees and plants not just for our paper, pencils, or even furniture, but something much greater than any of these things put together. Indeed having a low costly grocery store within walking distance is pleasant, but there are negative consequences as well as positive consequences that coincide with the placement of a Wal-Mart in the city of Oviedo. It is understood to many that industrialization as well as being able to finally have a store that does not charge six dollars for orange juice is a blessing. Fretfully, the negative consequences will
No matter where a person lives, even if it is not near a rain forest, the complete destruction of rain forests will affect living conditions. For years rain forests have provided countries around the word with valuable resources, minerals, lumber, and energy. In Brazil alone the rain forests contains 45% of Brazil’s hydroelectric power. The minerals found in the rain forests of Brazil are estimated to value 1.6 trillion dollars, while the lumber that the rain forests can provide total 1.7 trillion dollars (“In the Forest” 1). Nutrients from decomposing organisms can be found throughout rain forests, including in soil and in trees. To continue destroying forests also destroys the important materials that they are providing to humans.
By definition, deforestation is the permanent destruction of forests in order to make the land available for other uses. Such as the conversion of forestland to farms, ranches, and urban use. Food and Agriculture Organization of the United Nations has reported that an estimated 18 million acres of forest are lost each year and about half of the world's tropical forests have been cleared. Also, according to Bastien Sachet, “…tropical deforestation is responsible for approximately 20% of world greenhouse gas emission…Every year, 13 million hectares of the world’...
On average millions of hectares of forests are destroyed each year resulting in severe consequences that will affect not only our lifestyle, but also all the animals with which we share our planet. Many species of animals and plants will become extinct and if we continue with the destruction of our forests, earth will be unable to sustain life.
“The Earth is 4.6 billion years old. Scaling to 46 years, human have been here 4 hours, the industrial revolution began 1 minute ago, and in that time, we’ve destroyed more than half the world’s forests.” - Unknown. One major environmental problem in our world is deforestation - what is that, you ask? According to the Merriam Webster Dictionary, deforestation is the action or process of clearing of forests. Some consequences of this include a large contribution to global warming and climate change (about 1.5 billion tons of carbon dioxide each year), loss of biodiversity especially in tropical rainforests, and the extinction of many known or yet to be discovered species. But, through some Debt-for-Nature Swaps, leaving forests
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
This is alarming since recent data indicates these enormous forests are land-dwelling carbon absorbers that could help to slow worldwide climate alteration. The United Nations ' Food and Agriculture Organization (FAO) estimates “eighteen million acres of forests have been destroyed worldwide;” and NASA forecasts “that if current deforestation rates are not reduced, rainforests could become entirely eradicated in a century.” The nations with substantial deforestation are Brazil, Indonesia, Thailand, Africa (The Democratic Republic of Congo included), and remote areas of Eastern Europe. Indonesia, the country with the greatest deforestation within the last century, has lost approximately forty million acres of indigenous
The human heart has two ventricles and two atria making up four chambers. The heart includes the atria and ventricles. The left atrium and the left ventricle make up the left side of the heart and the right atrium and right ventricle make up the right side of the heart. Each side is important but the left ventricle and left atrium is the most important, and I will tell you why. The left ventricle receives blood from the left atrium and pumps into the aorta. The aorta pumps oxygenated blood to the rest of the body. If someone shot you in your left ventricle, you would most certainly die. That is why it is the most important. It pumps blood to the rest of your body. The right ventricle is important too. The right ventricle receives blood from the right atrium and pumps blood to the pulmonary artery. The pulmonary artery ha...
What is also becoming increasingly clear is the effect that forests have on the climate and the climate has on forests, and how changes in one system will affect the other. Losing forest makes it worse. Clearing forests also releases large amounts of carbon dioxide. Worldwide deforestation means we don’t have as many trees to absorb the extra CO2. This means more of it stays in the atmosphere, trapping more heat. Forest are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. The biggest driver of deforestation is agriculture. Farmers cut forest to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in process known as “ slash and burn” agriculture. Therefore, not all deforestations is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. Deforestations has many negative effects on the environment. The most dramatic impact is a loss of habitat for million of species. So seventy percent of Earth’s land animals and plants live in forest, and many cannot survive the deforestation that destroy their homes. A more workable solution is to carefully manage
People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
Scientists themselves are just beginning to understand the serious problems caused by deforestation. Deforestation occurs all over the world by all types of people. Peasant farmers even add to the problem because in most tropical countries the farmers are very poor only making between eight hundred and fifty four hundred dollars annually (NASA Facts). Therefore, they do not have enough money to buy what they need to live therefore they must farm to raise crops for food and to sell. In these poor countries the majority of people are peasant farmers this farming adds up to a great deal of deforestation. These farmers chop down a small area of trees for there plot to farm on and burn the tree trunks (NASA Facts). The combined number of farmers maintaining this process creates a great deal of clearing and burning of the land they need to cultivate, which results in land being treeless. Commercial logging is also another common form of deforestation. This commercial logging wipes out massive amounts of land sometimes deforesting several miles at...
There is powerful evidence showing that clearing tress not only spews carbon into the atmosphere, it also leads to major shifts such as increased temperatures and rainfall worldwide
