Don’t take our word for it - see why 10 million students trust us with their essay needs.
Most of us know what rainforests are, and how they can benefit us. But, only few of us know what rainforest do, and how they are most important to Earth. There are two types of rainforests; tropical and temperate rainforest. Tropical rainforest are known mostly for its rich evergreen vegetation. Also, being a home for over 50 percent of the Earth’s living species. Even though, it holds about 7 percent of landmass on Earth. A Tropical Rainforest is a broad leaved evergreen forest, which has high rainfall. These are found around the Equator. Specifically, Central America, South America, Southern Asia, and Australia (which however, goes through a dry spell twice a year). The Amazon Rainforest is the largest tropical rainforest in the world; located in northern South America. It is three million square miles. Which is nearly the size of the United States. Tropical Rainforest have warm temperatures year around, and high rain fall. Temperate Rainforest, however, are smaller than Tropical Rain Forest. But they have mostly, coniferous vegetation and are known for its cooler climate. They are located in Norway, Chile, Tasmania, the United Kingdom, New Zealand, and along the Pacific coast of Canada and the United States. In contrast to Tropical Rainforest. Temperate rainforest have cool temperatures here year round, but manages to have 5 to 16 feet of rain a year. This kind of climate produces plants like, Redwood trees and large conifers.
Rainforests are the largest biome, which has the largest biodiversity. Because of this, scientist have used them for human luxuries. Such as coffee, soft drinks, chewing gum, toothpaste, medicine, and so much more. 70 percent of plants identified, by the U.S National Cancer Institutes, found in rainforest...

Rainforest can be very moist, hot, and humid due to all of the rainfall. The average rainfall is
Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%.

Geographical location- basically, tropical rainforest is roughly taking place within the latitude 28 degrees north or south of the equator, concentrated in South America at the same time, scattered in Africa and south Asia. The Peninsula de osa in Costa Rica , which is located in the middle America, bordering both the Caribbean Sea and the North Pacific Ocean, between Nicaragua and Panama. It is a country with tropical climate in four seasons; it is usually hot and humid, which nurture beautiful
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.
Amazon: This is one of the most famous tropical rainforest in the world. Currently, it is the largest tropical rainforest in the world. The forest covers the basin of amazon, the world’s second longest river. The Amazon is home to many animals and even some of the plants greats. This rainforest has a great variety of plants and animals. 1/5 of the world’s plants and 1/10 of all mammal species are found there.
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.
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.
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.
In South America lies the largest and most wondrous rainforest in the world, the Amazon Rainforest. This 1.4 billion acre forest represents over half of the planet's remaining rainforests, and comprises the largest and most bio-diverse tract of rainforest in the world. Ten percent of all known species on the planet are found in this rain forest, most of which have yet to be discovered. For the past century, the Amazon has been gradually decreasing in size due to agricultural expansion, ranching, infrastructure projects, energy exploration and illegal logging. In its current state, the Amazon is losing land equal to the size of the state of Delaware every year.

Tropical rainforests have many species of plants and animals. They are very interesting and many scientists today study it. Rainforests are an important part of our environment and it is important for us to protect it. That’s why we have to stop global warming.
