Tropical forests of all varieties are disappearing rapidly as humans clear the natural landscape to make room for farms and pastures, to harvest timber for construction and fuel, and to build roads and urban areas.
Why are humans destroying the rainforest?
The main reasons for humans destroying tropical rainforests are mostly economic. More than half of the Earth’s rainforests have already been lost forever to the uncontrollable human demand for wood and farmable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent.
Should rainforest destruction be punished?
So what should we do? Rainforests destruction should be punished. When someone cuts hundreds of thousands of trees in a rainforest, they aren’t only hurting themselves, they are hurting the entire human race too. If we truly abide by the fact that ‘your rights end where mine begin’, then rainforests destruction isn’t a right for anyone.

What are the causes of forest dieback?
Forest dieback is strongly interconnected with other phenomena such as the melting of the Greenland ice sheet, which would cause sea levels to rise , and the degradation of frozen soil in the Arctic known as the permafrost, which would release greenhouse gases held in the ice as well as long-dormant diseases.
Why is the rainforest called the rain forest?
The rain forest is so-called because it’s such a wet place, where the trees pull up water from the earth that then gathers in the atmosphere to become rain.

With nearly a fifth of the forest lost already, scientists believe that tipping point will be reached at 20% to 25% of deforestation. The Amazon is 10 million years old.
What is the land grabber in the Amazon rainforest?
The land is demarcated, often illegally, and lots are typically sold for a few hundred dollars by grileiros, or “land grabbers,” to poor farmers, who raze the forest and build communities. Over time, electricity and phone lines arrive, and the jaguars that threaten the cattle disappear from the landscape.
When will the Amazon be without trees?
of the Amazon will be without trees by 2030. Source: WWF. The fires that raged across the Amazon in August helped illuminate something the world can no longer ignore. Inside the crucible of this ancient forest, relentless colonization is combining with environmental vandalism and a warming climate to create a crisis.
How much carbon is in the Amazon forest?
The forces set in play in the Amazon could have serious global consequences. The forest stores up to 120 billion metric tons of carbon, equivalent to almost 12 years of global emissions at current rates. If cleared, much of that will go into the atmosphere. That alone could push the global climate beyond safe limits.
Why are tropical forests disappearing?

How does deforestation affect biodiversity?
Impacts of Deforestation: Biodiversity Impacts. Although tropical forests cover only about 7 percent of the Earth’s dry land, they probably harbor about half of all species on Earth. Many species are so specialized to microhabitats within the forest that they can only be found in small areas.
What does NASA do to help the tropical forest?
NASA supports and conducts research on tropical forests from space-based and ground-based perspectives, helping provide the information that national and international leaders need to develop strategies for sustaining human populations and preserving tropical forest biodiversity. (Photograph courtesy U. S. Forest Service.)
What happens when you deforestation a farm?
When an area is completely deforested for farming, the farmer typically burns the trees and vegetation to create a fertilizing layer of ash. After this slash-and-burn deforestation, the nutrient reservoir is lost, flooding and erosion rates are high, and soils often become unable to support crops in just a few years.
What are the products of the rainforest?
First, global markets consume rainforest products that depend on sustainable harvesting: latex, cork, fruit, nuts, timber, fibers, spices, natural oils and resins, and medicines. In addition, the genetic diversity of tropical forests is basically the deepest end of the planetary gene pool.
What is the belt of forests?
Stretching out from the equator on all Earth’s land surfaces is a wide belt of forests of amazing diversity and productivity. Tropical forests include dense rainforests, where rainfall is abundant year-round; seasonally moist forests, where rainfall is abundant, but seasonal; and drier, more open woodlands. Tropical forests of all varieties are ...
Where is the most of the nutrient content in a tropical forest?
Nearly all the nutrient content of a tropical forest is in the living plants and the decomposing litter on the forest floor. Tropical forests contain more species than any other ecosystem, as well as a higher proportion of endemic (unique) species.
What are the causes of the destruction of the rainforest?
Humans are the main cause of rainforest destruction. We are cutting down rainforests for many reasons, including: 1 wood for both timber and making fires; 2 agriculture for both small and large farms; 3 land for poor farmers who don’t have anywhere else to live; 4 grazing land for cattle; 5 pulp for making paper; 6 road construction; and 7 extraction of minerals and energy.
Why are we cutting down rainforests?
We are cutting down rainforests for many reasons, including: wood for both timber and making fires; agriculture for both small and large farms; land for poor farmers who don’t have anywhere else to live; extraction of minerals and energy.
What causes the death of trees in the Amazon?
Drought causes die-offs of trees and dries out leaf litter, increasing the risk of forest fires, which are often set by land developers, ranchers, plantation owners, speculators, and loggers. In 2005, 2010, and 2015 the Amazon experienced the worst droughts ever recorded.
How did the burning of the Mississippi River affect the climate?
The smoke caused widespread health problems, interfered with transportation, and blocked the formation of rain clouds, while the burning contributed huge amounts of carbon dioxide to the atmosphere, worsening the effects of climate change.

Which country has cut down 95% of its forests?
The worst offender is El Salvador, which cut down 95% of its forests. In other words, pristine areas, like the wilderness in Central America's east coast, will someday disappear and have highways going down them.
Why don't environmentalists talk about overpopulation?
Environmentalists don't talk about overpopulation because they would lose many of their supporters if they did. Some say, "Don't worry, the population growth rate is decreasing.". Population declines are regional and temporary. I'm currently in Eastern Europe where the population is indeed declining.
What happens when a country's reproduction rate falls below the replacement rate of 2.1?
The point is that when a country's reproduction rate falls below the replacement rate of 2.1, governments ultimately respond with incentives to reproduce. Therefore, no country stays below the replacement rate for long.Thus, the world, as a whole, will continue its exponential growth.
Why are they disappearing?
Rainforests are very important but they are disappearing very quickly. They used to cover 14% of the world but now only 6% of the world. If this keeps up, our rainforests are estimated to disappear in 40 years.
How can we help them?
To save the rainforests is going to be hard but if you follow these steps it will make it a bit easier.
Why are they so important?
Rainforests are so important because they create the rain that we get. Everything in the rainforests is very damp so that's were it gets the rain. All the trees there also create our oxygen. They suck up the carbon dioxide (bad air) and release the nice air we breathe (oxygen).
How does deforestation affect climate?
Tropical deforestation causes carbon dioxide, the main greenhouse gas, to linger in the atmosphere and trap solar radiation. This raises temperatures and leads to climate change: deforestation in Latin America, Asia and Africa can affect rainfall and weather everywhere from the US Midwest, to Europe and China.
What is the mechanism that reduces deforestation and forest degradation?
In addition, a new UN-backed mechanism called Redd (reduced emissions from deforestation and forest degradation) has been initiated that involves rich countries paying countries to protect forests and the carbon stored within them.
How many hectares of forest are felled every year?
Every year about 18m hectares of forest – an area the size of England and Wales – is felled. In just 40 years, possibly 1bn hectares, the equivalent of Europe, has gone. Half the world’s rainforests have been razed in a century, and the latest satellite analysis shows that in the last 15 years new hotspots have emerged from Cambodia to Liberia.

Is it possible to stop tropical deforestation?
Until Paris, stopping tropical deforestation was at best unlikely and probably impossible. It remains very difficult, but a political and financial mechanism has now been created to incentivise countries, companies and communities to do so at a fraction of the cost of reducing comparable emissions in the US or Europe.
Can tropical countries receive public funding?
Tropical and sub-tropical countries could receive both public and private funding if they succeed in reducing their emissions from deforestation. But this is deeply controversial as global schemes are prone to corruption, difficult to implement and hard to measure.
Will the rainforests vanish in a century?
John Vidal. At current rates of deforestation, rainforests will vanish altogether in a century. Stopping climate change will remain an elusive goal unless poor nations are helped to preserve them.
