There is political expediency in altering the current scenario where the water in Lake Okeechobee is discharged to the west and east, via the Caloosahatchee and the St Lucie rivers respectively, when it fills up and threatens to overflow. Soil in deforested areas is exposed to more sunlight, which increases the soil temperature and oxidizes the carbon in the soil to carbon dioxide. The breakdown of the natural chain of life was so starkly apparent to Floridians that it became a battleground in the midterm elections. Large scale destruction of treesdeforestationaffects ecosystems, climate, and even increases risk for zoonotic diseases spreading to humans. Deforestation refers to the intentional clearing of forest lands for urban expansion, cattle farming, agricultural cropland, and other human purposes. Conversion of forests to land used for other purposes has a long history. , Wind. Plants create oxygen and absorb greenhouse gases. Hurricane Irma tore up much of what remained last year, uprooting mangroves that had managed to survive the surging salt. When deforestation occurs, temperature variates more drastically from day to night and this extreme change can often prove fatal for many animal species. A mans world? Conservation costs money, while profits from timber, charcoal, pasture and cropland drive people to cut down forests, adds EDF. (How deforestation is leading to more infectious diseases in humans.). Not according to biology or history. The main effect of deforestation on animals and plants is the loss of their habitat. Which travel companies promote harmful wildlife activities? Eco-friendly burial alternatives, explained. Bornean and Sumatranorangutansare especiallyiconicspecies threatened by the expansion of oil palm farming in Indonesia. One possible indirect consequence of deforestation is the spread of diseases, including those originating from birds, such as avian flu. In some cases, however, even partial logging and accidental fires thin out the trees enough to change the forest structure dramatically. This field is for validation purposes and should be left unchanged. Knowledge awaits. As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change. While food availability for Indigenous tribes and animals that live in forests is reduced in the process of deforestation, its effects on weather patterns and soil degradation also drastically decrease agricultural productivity. He and his colleagues are beginning work with the Malaysian government to incorporate this into land use planning, and are undertaking a similar project with Liberian officials to calculate the cost of Lassa fever outbreaks there. Increased Greenhouse Gases. For instance, in Liberia forest clearings for palm oil plantations attract hordes of typically forest-dwelling mice, lured there by the abundance of palm fruit around plantations and settlements. The water here is shallow but still impenetrably murky, with the odd strand of seagrass floating by. A mans world? However, if crops are introduced on a smaller scale and don't displace native species, they can actually increase diversity since they can act as a habitat for birds and herbivores. Through land erosion, the soil is depleted of its nutrients, a huge source of nourishment for animals and plants. Let us know if you have suggestions to improve this article (requires login). Populations located in the proximity of tropical forests are mostly impacted by the worsening trend. The main effect of deforestation on animals and plants A massive 41 percent of tropical deforestation 2.1 million hectares a year is directly linked to the expansion of pasture for grazing beef cattle, mostly in Brazil. Tropical tree cover alone can provide 23 percent of the climate mitigation needed to meet goals set in the Paris Agreement in 2015, according to one estimate. Biodiversity is the number of species in a given ecosystem. Heres why each season begins twice. They live in settled villages by the rivers, and grow and hunt their food. Studies show that, 15,3 billion trees are chopped down every year. At least 2 million square km (772,204 square miles) of such forests have been cleared for grazing lands. Figure 1: Tropical primary forest loss between 2002 and 2020. Although most of the areas cleared for crops and grazing represent permanent and continuing deforestation, deforestation can be transient. The current rate of rainforest-loss generated emissions is nearly 25% higher than those generated in the European Union and just slightly below US levels. As widespread burning continues today in tropical forests in the Amazon, and some parts of Africa and Southeast Asia, experts have expressed concern about the health of people living at the frontiers of deforestation. This area, just last year smelled like death. Environmentalists are optimistic that the initial success of REDD in Brazil bodes well for reducing deforestation in other parts of the tropics as well. Among the main reasons for this damaging practice are agricultural expansion and cattle breeding as well as to obtain raw materials such as palm oil, a key ingredient in cosmetics and food products widely used around the world, and timber used for fuel, manufacturing, and infrastructure development. While food availability for Indigenous tribes and animals that live in forests is reduced in the process of deforestation, its effects on weather patterns and soil degradation also drastically decrease agricultural productivity. Smothered in haze, the trees couldnt produce fruit, leaving resident fruit bats with no other option than to fly elsewhere in search of food, carrying with them a deadly disease. On top of known diseases, scientists fear that a number of yet-unknown deadly diseases are lurking in forests that could be exposed as people encroach further. How did this mountain lion reach an uninhabited island? The scientific consensus on deforestation is that it intensifies climate change at a dramatic rate. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate. Climate change has accelerated the rate of ice loss across the continent. This can be done on an individual level, for example by reducing meat consumption, going paperless and recycling products as much as possible, opting for natural products that do not contain ingredients such as palm oil and supporting organisations and sustainable companies that are committed to reducing this dangerous practice. This isnt the time to give up.. In addition, each year fires burn an area about half as large as the areas that are cleared. Statistics show that deforestation in the tropics reduces precipitation over the Amazon by around 10%, or 138 millimeter, every year. Deforestation has become so rapid the world all over due to demand for agricultural land, food and fuel supplies. Subscribe: www.emagazine.com/subscribe. These are often plantations of eucalyptus or fast-growing pinesand almost always of species that are not native to the places where they are planted. The Florida Panther, representative of the only breeding subspecies of puma in the eastern U.S. American AlligatorsThe Eastern Indigo Snake, which nearly disappeared from Florida due to deforestation and construction projectsThe Key Deer, threatened by development projects in the Florida KeysMore items This makes soil vulnerable to being washed away, and prone to erosion. Those were the [places] that Anopheles darlingi really enjoyed being, Vittor recalls. The FAO estimates that there are approximately 1.3 million square km (500,000 square miles) of such plantations on Earth. maintaining Loss of Habitat. Not long after developers started draining the wetlands for agriculture and paved it over for roads and houses, the effects started rippling through the system. You might also like: 12 Major Companies Responsible for Deforestation. Unauthorized use is prohibited. An iceberg melts in the waters off Antarctica. All rights reserved. Participating nations can then accrue and sell carbon pollution credits when they can prove they have lowered deforestation below a baseline. A severe slump in rainfall in 2015 meant salinity levels rocketed in the bay, with the water becoming twice as salty in the ocean. Not long after the bats settled on trees in Malaysian orchards, pigs around them started to fall sickpresumably after eating fallen fruit the bats had nibbled onas did local pig farmers. Through careful surveys in the Peruvian Amazon, she found higher numbers of larvae in warm, partially shaded pools, the kind that form beside roads cut into forests and puddles behind debris where water is no longer taken up by trees. Deforestation is a major cause of soil erosion, perhaps the main cause. TimesMojo is a social question-and-answer website where you can get all the answers to your questions. Find out the causes, effects, and solutions. Photograph by Richard Barnes, Nat Geo Image Collection. One last major effect of deforestation is its impact on food security through the loss of biodiversity. Forests, a vital component of life on Earth, cover approximately 31% of our planets land area. The commercial palm oil industry rapidly expanded in the late 20th century and led to thedeforestationof significant swaths of Indonesia and Malaysia as well as large areas in Africa.

Earths croplands, which cover about 49 million square km (18.9 million square miles), are mostly deforested land. From logging, agricultural production and other economic activities, deforestation adds more atmospheric CO2 than the sum total of cars and trucks on the world's roads, Dear EarthTalk: Is it true that cutting and burning trees adds more global warming pollution to the atmosphere than all the cars and trucks in the world combined? Mitchell Vale, Houston. Rill erosion happens with heavy rains and usually creates smalls rills over hillsides; Gully erosion when water runoff removes soil along drainage lines. We are completely changing the structure of the forest, notes Carlos Zambrana-Torrelio, a disease ecologist at Ecohealth Alliance. On a governmental level, the consequences of deforestation can be mitigated by introducing policies that protect natural forests and regulate mining and logging operations as well as other operations that require the destruction of tree plantations. Forests cover about 30 percent of the planet, but these habitats are being cleared on a massive scale. The REDD program has channeled over $117 million in direct financial aid and educational support into national deforestation reduction efforts in 44 developing countries across Africa, Asia and Latin America since its 2008 inception. Photograph by William Daniels, Nat Geo Image Collection. Creating your LandScope profile is fast, free, and simple. The minerals in the water are almost like sandpaper on the rock, slowly, slowly scrubbing it away. Deforestation is the clearing of forests to obtain lumber and provide space for either agricultural zones or urban development. Yet the mass destruction of treesdeforestationcontinues, sacrificing the long-term benefits of standing trees for short-term gain of fuel, and materials for manufacturing and construction. In the Amazon, cattle ranching and farmsparticularly soy plantationsare key culprits. In 2014, for example, the Ebola virus killed over 11,000 people in West Africa after fruit bats transmitted the disease to a toddler who was playing near trees where bats were roosting. By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the worlds roads. This water replenishes clouds and maintains rainfall. Studies in the Amazon reveal that about 5,000 square km (1,931 square miles) are at least partially logged each year. Deforested lands are being replanted in some areas. Over time, that adds up, outweighing the profits that could be gained by cutting forests down and making a compelling financial argument to leave some forests standing, Daszak says. How does human activities cause soil erosion? Climate change has already affected migration patterns, and infected birds may move to deforested areas that are more suitable habitats for them, spreading their diseases to the local bird populations. Send questions to: earthtalk@emagazine.com. As a result of massive global urbanization and agricultural development, deforestation is a major factor contributing to climate change. With wild habitats destroyed and human life ever expanding, the line between animal and human areas blurs, opening the door to zoonotic diseases. They range from rainforests that are hot and wet year-round to forests that are merely humid and moist, to those in which trees in varying proportions lose their leaves in the dry season, and to dry open woodlands. Diseases that are transmitted through insects, such as malaria and Lyme disease, are more common in open spaces with more sunlight exposure. Copyright 2023 NatureServe. On average, they found that the Malaysian government spends around $5,000 to treat each new malaria patient in the regionin some areas much more than they spend on malaria control, Zambrana-Torrelio says. Thanks for reading Scientific American. Articles from Britannica Encyclopedias for elementary and high school students. To learn about the history of habitat loss in Florida, check out the Florida Fish and Wildlife Conservation Commission Report, Florida Vegetation 2003 and Land Use Change Between 1985-89 and 2003. A severe slump in rainfall in 2015 meant salinity levels rocketed in the bay, with the water becoming twice as salty in the ocean. There are some 250 million people who live in forest and savannah areas and depend on them for subsistence and incomemany of them among the worlds rural poor. Bats and agaves make tequila possibleand theyre both at risk, This empress was the most dangerous woman in Rome. Wildlife habitat has declined and even disappeared during the past 100 years as natural lands were converted to agriculture, range lands, and expanding urban areas. To meet the needs of the rapidly growing human population and protect global food supplies, agricultural expansion has occurred on a massive scale, accounting for 90% of deforestation What are the 3 major causes of soil erosion? Significance. Diseases can also occur when new habitats draw disease-carrying species out of the forest. Forests around the world are home to more than 80% of all terrestrial animal, plant, and insect species. Wind can also make soil erode by displacing it. For example, starting in 2017, the government of New Zealand sought to plant more than 100 million trees per year within its borders, but perhaps the most ambitious replanting project took place in India on a single day in 2017, when citizens planted some 66 million trees. In conclusion, deforestation, while it may be necessary, will have an extremely negative effect on the environment. Although there are many benefits that can be enjoyed through it, its risks cannot be ignored. Many deforestation efforts focus only on short-term gains and think nothing of the long-term risks and consequences. These skeletons may have the answer, Scientists are making advancements in birth controlfor men, Blood cleaning? Can we bring a species back from the brink?, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC. Water is the most common cause of soil erosion. Forests cover about 30 percent of the planet's land mass, but humans are cutting them down, clearing these essential habitats on a massive scale. We promise, no spam! The numbers are grim, but many conservationists see reasons for hope. Figure 1: Tropical primary forest loss between 2002 and 2020. As the world seeks to slow the pace of climate change, preserve wildlife, and support more than eight billion people, trees inevitably hold a major part of the answer. Its hard to generalize about mosquito ecology, which varies depending on species and region, Vittor stresses. To answer the question of how deforestation affects the environment, it is important to look at why humans need forests in the first place. When does spring start? In the South Asian Monsoon region, the reduction in rainfall is even higher, with around 18% less rain recorded in India in a single year. For instance, forests perform important functions like: regulating weather conditions. One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. By the 1960s, scientists had calculated that while around 2m acre feet (2.5bn cubic metres) of water once flowed in a shallow river of grass from central Florida to the states southern tip, the volume of this conveyor belt had been cut in half. Examples include using less land (and therefore cutting fewer trees) for activities such as coffee growing and meat and milk production. Obviously, this is the biggest effect of soil erosion. Our editors will review what youve submitted and determine whether to revise the article. And in Brazil, conservationists are rallying in the face of ominous signals that the government may roll back forest protections. When does spring start? But humans can become unwitting hosts for pathogens when they venture into or change forest habitat. reducing carbon dioxide (CO 2) in the atmosphere. Corrections? Water sources in deforested areas were shown to have higher nitrate levels, lower dissolved oxygen levels, and somewhat higher temperatures (from 20 to 23 degrees Celsius on average) than in forested areas. They write new content and verify and edit content received from contributors. Discover world-changing science. Unless we change the present system that rewards forest destruction, forest clearing will put another 200 billion tons of carbon into the atmosphere in coming decades, says EDF. But its hard to convince the poor residents of the Amazon basin and other tropical regions of the world to stop cutting down trees when the forests are still worth more dead than alive. Removing trees deprives the forest of portions of its canopy, which blocks the suns rays during the day and retains heat at night. Identify Priority Places: A Practitioner's Guide, Florida Vegetation 2003 and Land Use Change Between 1985-89 and 2003. We need trees for a variety of reasons, not least of which is that they absorb the carbon dioxide we exhale and the heat-trapping greenhouse gases that human activities emit. In recent decades, Floridas massive population growth and booming tourism industry have disturbed and fragmented many natural areas across the state. What is the difference between deforestation and logging? Deforestation is the mass destruction of trees in a forest. Often in an effort to clear a large area of land and convert it to a non-forest use. While logging is simply the act of cutting down trees for the purpose of making timber. These skeletons may have the answer, Scientists are making advancements in birth controlfor men, Blood cleaning? Since different species eat different foods and live in different types of habitats, a diverse set of vegetation can enable a greater variety of animals to live in an area. Separate red tide algal outbreaks in the ocean ravaged Florida last year, leading to beaches being closed, horrified dog owners who saw their pets poisoned, and hundreds of tons of dead fish and manatees piling up along the Gulf coast. By 1999, 265 people had developed a severe brain inflammation, and 105 had died. Along with Indigenous tribes, animals are some of the biggest victims of deforestation. One solution, Davis and other advocates believe, is to create a vast reservoir south of Lake Okeechobee that would store water intended for the Everglades. Although wind usually erodes soil more slowly than water, Florida does have an active hurricane season from June to November. Most present-day croplands receive enough rain and are warm enough to have once supported forests of one kind or another. Can we bring a species back from the brink? Impact of Deforestation - Species Loss, Extinction and Disease A fully functioning forest has a great capacity to regenerate. How a zoo break-in changed the life of an owl called Flaco, Naked mole rats are fertile until they die, study finds. Ephemeral erosion that occurs in natural depressions. Deforestation represents one of the largest issues in global land use. If tropical deforestation were a country, according to the World Resources Institute, it would rank third in carbon dioxide-equivalent emissions, behind China and the U.S. Can Cell Phones Help Save Rain Forests? All told, deforestation causes a triple-whammy of global warming: We lose a crucial ally in keeping excess carbon out of the atmosphere (and in slowing global warming), Even more emissions are created when felled trees release the carbon theyd been storing, and rot or burn on the forest floor, and Notice how turbid and brown the water is, Davis said, standing up on his skiff and peering into the bay. While deforestation may occur locally, its effect is global. Few places exist in eastern North America that retain stands of uncut old-growth forests. Zambrana-Torrelio notes that the likelihood of spillovers to people may increase as the climate warms, pushing animals, along with the viruses they carry, into regions where theyve never existed before, he says. Scientists just confirmed a 30-foot void first detected inside the monument years ago. Typically, the land produces for only a few years and then must be abandoned and new patches of forest burned. Can we bring a species back from the brink?, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC. What is deforestation? , Cattle ranching and deforestation are strongest in Latin America. However, the bacterium is also found in the white-footed mouse, which happens to thrive in forests fragmented by human settlements, MacDonald says. This can be done on an individual level, for example by reducing meat consumption, going paperless and recycling products as much as possible, opting for natural products that do not contain ingredients such as palm oil and supporting organisations and sustainable companies that are committed to reducing this dangerous practice. Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. In the case of the Amazon rainforest, research shows that, would be needed in order to keep the hydrological cycle going. Only about 1 million square km (390,000 square miles) of cropland are in areas that would have been cool boreal forests, as in Scandinavia and northern Canada. Unauthorized use is prohibited. , Urbanization and Other Types of Land Development.
