Deforestation is a major contributor to global greenhouse gas emissions, with the main greenhouse gases being carbon dioxide (CO). Deforestation, which is primarily driven by agriculture, contributes 12-20% of global greenhouse gas emissions. Forest degradation, which negatively affects a forest’s structure or function but also contributes to climate change, is another significant factor. Since 1850, about 30% of all CO2 emissions have come from deforestation.
Deforestation can also have local climate impacts, as trees release moisture that cools the air around them. The persistence of ozone and methane, both greenhouse gases, results in a biogeochemical warming effect. The net effect of forest biodiversity loss on both local and global scales remains uncertain. As of 2019, deforestation is responsible for about 11 percent of global greenhouse gas emissions.
When forests are cleared or disturbed, they release stored carbon dioxide back into the atmosphere, contributing to climate change. The largest amounts of deforestation occurred across the humid tropics, mainly in Africa and South America. Trees absorb excess carbon dioxide under normal conditions, and when forests are burned or cut down, the accumulated carbon dioxide is released.
The use of fossil fuels is the primary source of CO2 emissions, but the removal of trees from forested land has also contributed. Greenhouse gases are emitted during the burning of forest biomass and decomposition of remaining plant material and soil carbon. The loss of forests contributes up to 30 percent of global greenhouse-gas emissions each year, rivaling emissions from the global transportation sector. Trees capture greenhouse gases like carbon dioxide, preventing them from accumulating in the atmosphere and warming our planet.

Is deforestation the main cause of the greenhouse effect?
Deforestation is a significant contributor to global warming, as it releases carbon dioxide and other greenhouse gases. Trees absorb and store carbon dioxide, and deforestation releases these gases. Around 10% of global warming is caused by forest loss and damage. Most deforestation is done for food production, with the majority of the destruction linked to meat, soya, and palm oil. Tropical forests are cleared to grow soya for feeding farm animals, meeting the global demand for cheap meat. Stopping deforestation is crucial to combat the climate crisis and protect the environment.
What is the effect of deforestation on global warming?
Deforestation is the intentional removal of trees and forests, releasing carbon dioxide into the atmosphere, contributing to climate change. The largest deforestation occurred in the humid tropics, primarily in Africa and South America, between 1990 and 2020. The UN Food and Agriculture Organisation estimates that around 420 million hectares of forest were lost between 1990 and 2020. The annual rate of deforestation has slowed but remains 10 million hectares per year between 2015 and 2020.
The primary driver of deforestation is the global demand for agricultural commodities, such as palm oil and soya, and cattle ranching. Land use change, primarily deforestation, contributes 12-20% of global greenhouse gas emissions. Forest degradation and the destruction of tropical peatlands also contribute to these emissions. As a result, some tropical forests emit more carbon than they capture, turning them from a carbon sink into a carbon source.

The primary driver of deforestation is the global demand for agricultural commodities, with agribusinesses clearing vast tracts of forest to plant high-value cash crops like palm oil and soya. Deforestation and degradation contribute to 12-20% of global greenhouse gas emissions, with some tropical forests emitting more carbon than they capture.
REDD+, a family of policies, provides financial incentives to governments, agribusinesses, and communities to maintain and potentially increase forest cover. The plus in REDD+ refers to the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks in developing countries. Incentives for forest protection are offered to countries, communities, and individual landowners in exchange for slowing deforestation and promoting reforestation and sustainable forest management. Proper involvement of local people in the REDD+ process may also help alleviate rural poverty.

What are the five effects of deforestation?
Deforestation is the deliberate clearing of forest land, leading to climate change, increased temperature and pollution, desertification, soil erosion, greenhouse gas increase, groundwater decrease, and loss of food and habitat for animals, resulting in their extinction. Deforestation is a result of various factors such as agricultural clearing, industrialization, urbanization, wood extraction, natural calamities, and mining. It also contributes to the increase in greenhouse gases, groundwater levels, and the loss of food and habitat for animals.
How does deforestation lead to global warming class 8?
Deforestation is a process that generates raw materials for various industries, including agriculture, wood, and construction. It is primarily driven by agriculture and cattle grazing, which leads to the conversion of forest land into agricultural land. This process can lead to overpopulation and the accumulation of carbon dioxide in the atmosphere, which traps heat rays and contributes to global warming.
What happens to the greenhouse effect when you burn fossil fuels?
Fossil fuels, derived from the decomposition of buried carbon-based organisms, release large amounts of carbon dioxide into the atmosphere, trapping heat and causing global warming. The average global temperature has already increased by 1C, and warming above 1. 5°C risks further sea level rise, extreme weather, biodiversity loss, species extinction, food scarcity, worsening health, and poverty for millions of people worldwide. Fossil fuels, including coal, oil, and gas, are non-renewable and currently supply around 80 percent of the world’s energy.
The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming, with 89 of global CO2 emissions in 2018 coming from fossil fuels and industry.
How the greenhouse effect is caused by the burning of fossil fuels and deforestation?
The burning of fossil fuels, deforestation, and livestock farming are causing a significant increase in greenhouse gases, leading to global warming. The 2011-2020 decade was the warmest, with the global average temperature reaching 1. 1°C above pre-industrial levels in 2019. Human-induced global warming is currently increasing at a rate of 0. 2°C per decade, with a 2°C increase compared to pre-industrial times posing serious environmental and human health risks, including the risk of catastrophic changes.
Which greenhouse gas is produced by either deforestation?
Deforestation and soil degradation contribute to the increase of carbon dioxide in the atmosphere, while forest regrowth removes it. These emissions are primarily resulting from the production and transport of oil, natural gas, and coal. Human activities are the primary cause of climate change since the mid-20th century. The indicators in this chapter characterize the emissions of major greenhouse gases, their concentrations in the atmosphere, and their changes over time.
They use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents. As greenhouse gas emissions increase, they build up in the atmosphere, leading to climate change in the atmosphere, land, and oceans. These changes have both positive and negative effects on people, society, and the environment, including plants and animals. The warming effects on the climate persist over time, affecting both present and future generations. The EPA provides data on U. S. greenhouse gas emissions through the Inventory of U. S. Greenhouse Gas Emissions and Sinks and the Greenhouse Gas Reporting Program.
What is the main cause of the greenhouse effect?
The combustion of fossil fuels, such as coal and oil, has resulted in an increase in greenhouse gas concentrations due to the carbon-oxygen combustion process in the atmosphere.

I have witnessed this in Africa on a micro-level. I have seen land cleared for agriculture with an immediate drying up of once permanent streams, thus illuminating the only water sources for miles. I have witnessed the shortening of the raining season along with the extension and increased severity of the dry season in West Africa. I have seen the desert expand southward as the savanna turns into desert. The longer term consequences will affect us all globally.
Mother of 2020: dinosaurs used to be very big. But they’re all extinct. Kid: were they bad? Mother: they’d kill you alive. Kid: Thankyou God! A feew yeARs Laethor.. Mother of 2050: trees used to be very big. But they’re all extinct now. Kid: were they bad? Mother (changes topic): Lets hurry the oxygen cylinder might run out of stock!!
My response after seeing this article is that I am concerned about the deforestation, because forests play an important role in supporting life on earth. Forests are a source of oxygen that we breathe to survive. There will be many problems that arise if we continue to use the existing forest without replanting it. These problems are like the glass effect that arises from human activities that produce CO2 gas. If deforestation continues, no one absorbs CO2 further, the effect of these greenhouse gases cancels global fires which have an impact on glaciers, drought, forests, causing habitat for these animals to become extinct and causing the ecosystem on earth to become unbalanced.
When trees are felled, they do NOT release their carbon into the atmosphere. They do so, if they are burnt, or if they rot. Using timber for long term building material, to name one example, does in fact store the carbon, as long as the wood stays in its form. There are obviously still many reasons why deforestation and industrial scale timber harvestment have some big Issues, but i just wanted to correct this a little.
Thanks to this article about deforestation. This helps us understand the problems that we will face if humans continue global deforestation. It has many effects on animals. It causes of habitat destruction, agribusiness. This will reduced food availability, etc. Let’s do our part by sharing this article so people are aware of the problem we will be facing if deforestation continues.
Hutan sangat berperan penting bagi kehidupan makhluk hidup. Seperti yang telah dikatakan dalam article tersebut, bahwa hutan adalah habitat atau tempat tinggal bagi 80% tumbuhan dan hewan . Penggundulan hutan dapat menimbulkan efek yang sangat luar biasa. Efek yang akibatkan penggundulan hutan yaitu emisi gas rumah kaca yang menyebabkan efek rumah kaca. Seperti yang kita ketahui, efek rumah kaca berkaitan erat dengan pemanasan global. Oleh karena itu, pemanasan global akan semakin bertambah tiap tahunnya. Selain itu, efek sampingnyalagi adalah kepunahan. Sekitar 4 sampai 6 ribu spesies telah punah akibat penggundulan hutan. Sehingga keanekaragaman hayati dalam hutan tidaklah seimbang. Forests are very important for the life of living things. As has been said in the article, that the forest is a place to live for 80% of plants and animals. Deforestation can have biggest effects. The effect from deforestation is the emission of greenhouse gases which causes the greenhouse effect. As we know, the greenhouse effect is closely related to global warming. Therefore, global warming will increase every year. Besides, another side effect is extinction. About 4 to 6 thousand species have become extinct due to deforestation. So that the biodiversity in the forest is not balanced.
What this article mentions only briefly is how not all forestry and logging activities lead to deforestation. Deforestation occurs when the land is converted from forest land into another landuse. This is primarily happening in second and third world where they lack other opportunities for national income such as manufacturing, tech, etc. So land is cleared and converted into other uses such as cattle or plantations. Modern forestry in developed countries is based on 100+ years of science and experience to ensure that we will have forests in perpetuity. There are third party certifications that allow you to see that the wood based products you are purchasing are sourced sustainably. Sustainable Forestry Initiative (SFI) and Forest Stewardship Council (FSC) are two of the prominent ones. So next time you see a clearcut, don’t just assume that it will never grow trees again, it is more then likely that it will be replanted to grow trees for the next generation.
I think education and awareness is very important. A topper of class would not be able to give simple answer on environment or animals it is because school board is not supporting education related to environment and are sharing useless information. Any well educated person won, t be able to answer important information about animals. By making a mandatory subject related flora and fauna,which should be equally important like maths . This would not only save environment but also wildlife
Hutan merupakan bagian penting dari kehidupan di bumi, pada proses kelangsungan kehindupan makhluk hidup. Hutan juga menutupi sebagian dari planet bumi. Berdasarkan data yang diperoleh bahwa sebagian besar hewan, hutan merupakan tempat tinggal hewan dan tumbuhan. Terlebih lagi sebagian besar hewan di dunia hidup di daerah tropis. Tetapi dangan adanya defortasi berakibat pada jumlah gas rumah kaca di atmosfer. yang dimana semakin sedikit hutan, berarti akan menyebabkan lebih banyak efek rumah kaca memasuki lapisan atmosfer. terlebih lagi defortasi hutan dapat semakin berkurangnya keanekaragaman hayati. Dari sini dapat diketahui bahwa dampak utama dari adanya deforestasi adalah terjadinya penurunan kualitas atmosfer. Deforestasi berkontribusi pada pemanasan global yang terjadi karena adanya peningkatan konsentrasi gas rumah kaca (greenhouse gases) yang menyebabkan kenaikan suhu udara global.
I became vegan because I am very worried about deforestation. Only 6% of soya is for humans (94% goes to cows, chickens, and other farm animals). 80% of deforested land in Brazil is used to graze cattle. I also avoid palm oil where possible (e.g. when buying peanut butter, toiletries, and vegan burgers).
Mankind needs to move past animal agriculture for many reasons. For one thing, it would reduce zoonotic diseases like the current pandemic, and the last one in 1918 which sprang from an animal farm in Kansas. Here is another. “Eating a vegan diet could be the “single biggest way” to reduce your environmental impact on earth, a new study suggests. Researchers at the University of Oxford found that cutting meat and dairy products from your diet could reduce an individual’s carbon footprint from food by up to 73 per cent.Sep 24, 2020 Link on my website under “About.”
This article kinda toxic lol I’m a Forestry major and first thing we learn are the differences between controlled forests and “real” forests. The paper you use for your test or the Amazon boxes you receive by mail all come from these controlled forests, those are places you can cut down and manage regularly. These places exist so beautiful places like rainforests can stay untouched. We don’t go to Amazon rainforest and cut everything down, turn it into paper. I’m Brazilian and what’s destroying our rainforest is mostly cattle and fire (the CO2 problem). Soy is a problem too. The big forestry business are all certificated by FSC, which means you have to follow A BUNCH of rules not to destroy the environment.
In the 60’s there were documents published that showed the impact of trees on global warming and implications on national security. They found trees changed the tempreture of the air above them by decressing the tempreture by 2-3 degrees through evopotranspiration . Tree covered land vs barren land had a 10 degree difference in tempreture. One could change the entire countries tempreture by enlargening the countries forests. It estimated that north and south polar ice cap major melts may happen with a 100 meter rise in sea level which will inundate strategic military positions especially nuclear arsenals. It stated the highest chance of mass nuclear war would occur at this point due the advantage it gives Russia over USA because of geography and the 100meter water mark. However USA having nuclear capabilities all around the globe would naturaly counter. Apart for the obvious effects the nuclear mushroom clouds would disrupt high altitude wind currents and disturb weather patterns globaly. And if nuclear war didn’t occur then the new high tempreture, high water levels and lack of tree coverage would cause major damage to top soil and have a high potential of nuclear power facility meltdowns across the globe with food and drinking water becoming scare. I hope this possiblity doesnt happen. If your hopefully like me Cauvery Calling is a great charity that plants fruit trees that are taken care of. Two years ago their total tree count was 50million and this year its hit 60million.
From the economical point of view, how is a standing jungle a profit. Tree is just a commodity, right? People don’t pay for trees, and maybe, they should. Land development is not to let the trees grow. The land is developed when you build infrastructure like roads, electricity, water pipes, sewage, build houses for people to rent or buy and pay the bills, or build companies to sell or produce or assemble their goods. Our society does not support woods and jungle, animal life or clean air. We topple nature by developing technology to destroy what’s there from before, yet use the propaganda to convince others that more technology is the right way to meet nature. Get the religious and political competition on the top of it and you’ll understand that we don’t have any respect for the life we’ve been given.
So when you fell a tree they immediately release the CO2 ? What kind of bullshit is that ? 😀 The carbon dioxide is stored in the wood (cellulose, hemicellulose, lignin etc.) and isnt just released the second you fell it. Its released when you burn it for example. The other issue with the article and the description is the fact that they say that 30% of the planet is covered by forests. Thats also bullshit. Dont get me wrong, deforestation is a bad thing but as a Youtube website with over 6 million subscribers you cant just make up alternative facts. Only because your president does it, doesnt mean that you should also be doing it.
Let me break things to you all. Over 99% of all species that ever lived on Earth went extinct. The planet went throught temperatures way over anything climate change could ever cause, and way down what most animals and even plants could ever survive. The interest in stopping climate change, preventing current species from going extinct and stopping things like deforestation is selfish, and purely for our own benefit. Which is why we need to redouble efforts. Even if you think you don’t care about those, you tip the balance too much to the wrong side and the delicate ecossystem we depend on to live can come tumbling down just like it also happened for previous dominating species in past epochs. Because the planet isn’t going anywhere, and it would recover plenty fast overtime. Specially without us. Faster without us. The only thing poised to dramatically change if we do nothing is our own survival. We’ll most likely not survive the next big natural mass extinction event anyways, better make good use and stretch things as long as we can by NOT killing ourselves with out own hands and actions. Who knows? We could have a few millenia to enjoy as long as we don’t keep polluting and screwing around as much. We’re but a tiny tiny tiny blip in Earth’s timeline. Grain of sand in a beach, spec of dust floating around Earth’s in a nanosecond-like moment of it’s life. It’s quite funny when you think that among the other animals who ruled the planet through long periods of time, we might end up being among the most short lived.
Stop building new houses and stop cutting down trees. What needs cutting is how many babies couples should have one baby per couple. Forever. We should get rid of disposable nappies and if people dont change there then the world will force change, until people learn. Native Americans are right. More is less so keep taking then you will have less then this is when you will learn that actually less is more. People who have been flooded or had fire destroy their homes may have learnt a lesson due to their loss of possessions.
100 years before all rainforests are cleared ??? I cannot wait that long. Can we please cut these down faster. We can certainly use all that timber and we can create farmlands faster. We need better logging machines so that we can cut trees faster. I do not mind biodiversity loss …. I am OK with that.
