Recommended: Human impacts of rainforest paragraph
A rainforest is an area of high, mostly evergreen trees with a high amount of rainfall. The biome is the earth’s oldest living ecosystem, being incredibly complex and diverse. The importance of the rainforest, is the huge biodiversity of the place due to the 80 – 90% of species that can be found there, even when it only covers 6% of the Earth’s surface. It is also often called the lungs of the planet, by absorbing carbon dioxide and producing oxygen upon which many species depend on. Rainforests also help stabilize the world’s climate and maintain the water cycle by producing rainfall all around the planet. Every year humans are cutting down more and more rainforest all around the globe. The reasons for this deforestation are to have grazing land for cattle, contraction of roads, extraction of energy and minerals and many more. Yet this report will focus on the monoculture of rubber tree plantations on previous rainforest land.
Most of the positive implications of deforestation are for the economy. Rainforest land is cut down and converted into a monoculture rubber plantation, to provide necessary resources for humans, in this case rubber. There are not a lot of positive implications about deforestation and they are mostly overruled by the large

Monoculture rubber plantations have no biodiversity and need ongoing human intervention (including fertilization) because weeds must be removed using pesticides and herbicides. These chemicals have a huge impact on the natural species to the area and further contribute to the loss of biodiversity. Forests have a complex, rich-biodiversity, self-regenerating system, that consists of soil, a microclimate, water and a huge variety of animals and plants in mutual coexistence. When the complex forests get cleared, it causes an imbalance on the ecosystem of all of the species that help each other existences, contributing to the increase of the loss of
The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
The dense levels of vegetation absorb tremendous amounts of carbon dioxide in the atmosphere and help slow down the rate of climate change that the planet is experiencing. This process also produces high levels of oxygen that help to support life around the world. Coupled with the high levels of rainfall that benefit the water cycle, the rainforests are an integral part of the many systems that exist. These forests contain a wide variety of plants that a source of different chemicals that are used to create medicines. The degradation of these areas could potentially lead to the loss of medicines that could cure some of the deadliest diseases and illnesses that
Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .
The ecosystem I have chosen is tropical rainforest. In the following paragraphs, I am going to firstly introduced the structure of tropical rainforest in brief, with the second part of the plant ecology and last the diversity within this ecosystem.
The natural resource of wood is being used at an unsustainable rate, with minimal effort to change societal views on the depletion of this valuable natural resource. Much of the wood we use today comes from old-growth tropical forests, and in many regions it is harvested illegally. Recently in England, it was revealed that the major department store, Marks&Spencers, made much of its garden furniture out of Nyato wood which was logged illegally from Indonesian rainforests. Looking at this problem from a micro-level orientation, we can clearly see how the actions of individuals in both Britain and Indonesia affect one another.
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
The rain forests are incredible places. They only cover 6 % of the world’s surface however they have more than ½ the world’s plant and animals species. A rain forest can be described as tall and thick jungles. There is a reason behind the forest being called a “Rain forest” and it is because the high rainfall it gets per year. On average, 50 to 260 inches of rain falls yearly. The temperature in a rain forest rarely gets higher than 34 ºC or drops below 20 ºC. The average humidity in a rainforest is between 77 to 88%. Rainfall is often more than 100 inches a year.
There are many rainforests in the world but one of the biggest one is the Amazon rainforest, which is located in the northern half of South America and lies in the countries of Brazil, Colombia, Peru, Venezuela, Ecuador, and Bolivia. The Amazon also lies in between the Tropic of Capricorn and the Tropic of Cancer. The size of the Amazon resembles the size of the United States from the Atlantic Ocean to the Rocky Mountains. Since this rain forest lies next to the Equator, the climate is warm and humid. The average temperature is in between sixty-eight to ninety- three degrees. The Amazon has two seasons but each one is six months each. They are classified as the wet season and the dry season. The wet season occurs between December to May and the dry season occurs between June to November. The average rainfall is fifty to two hundred and sixty inches per year. The forest floor only gets up to two to five percent of sunlight since the canopy blocks the sunlight from getting to the forest floor. The Amazon rain forest got the nickname, the world’s pharmacy, because many medicines have been found in the tree bark, the tree’s leaves, and other parts of the trees.
Now is a critical time to address the issue of deforestation. Around the world forests are logged for timber and paper pulp. South America contains a large amount of mahogany and rosewood—highly coveted types of wood—within the Amazon basin. Forests are also cleared to make room for the planting of cash crops, such as coffee and soy, as well as livestock farms. After only a few years, overuse of these lands for crops typically causes soil erosion that quickly turns deforested regions into wastelands. Deforestation is responsible for 20 percent of global greenhouse gas emissions, which is more than all emissions all motorized transportation added together. The destruction of forests does not just threaten our climate; it threatens the livelihoods of billions of people that rely on forests for food and economic activities. The modern world relies on rainforests more than for the well-known reason. People receive many of their fruits and medicines from plant species that survive solely within the heart of a rainforest. Let’s not forget that forests also serve as habitats to wildlife a...
Thesis: Forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.
The Human Impact on Rainforests Human Impact on Rainforest is it a necessity? Rainforest are the beautiful gift of Mother Nature. It consists of the most magnificent species and plants in the world. 4.2% of the world’s animals live in the rainforest. This statistic it self shows how bad it would be to destroy such essential part of the worlds biodiversity.
Nowadays deforestation is the one of the most important and controversial environmental issues in the world. Deforestation is cutting down, clearing away or burning trees or forests. Particularly tropical rainforests are the most waning type of forests because of its location in developing countries such as Indonesia, the Philippines, India, central African countries and Brazil. Deforestation rate in those regions is high enough to worry about, because of large economic potential of forest areas. As the result of causes such as agriculture land expansion, logging for timber, fire blazing and settling infrastructure there might be serious impacts in future. For instance, extinction of endemic species of animals and plants which will be feral, increase of greenhouse gas emissions which may lead to global warming and consecutive catastrophes, destruction of home for indigenous residents which is considered as violation of human rights. Some people can argue with these drawbacks telling that deforestation have more valuable benefits such as growth of economics, production of food and providing better opportunities for life for poor families. However, these benefits are quite temporary and government of that countries and world organisations tries to halt deforestation proposing several solutions. Deforestation problem is especially acute in the Brazilian Amazon, where its rate is much high comparing with other regions. This paper will describe world-wide rainforests, causes and effects of deforestation, and evaluate possible solutions of deforestation in the Brazilian Amazon.
Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.
The Disappearing Rainforests Conserving the rainforest is a global issue of great importance. Tropical rainforests provide a habitat for animals, a unique ecosystem for vegetation, and an abundance of resources for humans, yet they are being destroyed at an astonishing rate. Experts estimate that if these endangered territories continue to be consumed in this manner, no more will be standing in forty years (Rainforest). Examining the social, environmental, and economic costs of the continued destruction of the Earth's tropical rainforests will prove that deforestation for short-term profit is ultimately not viable.
Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...
