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. Decades of often poisonous politics have pushed the Everglades, one of the largest and perhaps best-known wetlands in the world, down the path of entropy and potential collapse. At the turn of the century, there were over 600,000 cases a year in the Amazon basin. Since taking office in January, DeSantis has taken an unTrumpian approach to the environment, outlining a $2.5bn plan over four years to rescue the ailing Everglades. Another important role of trees is to regulate the temperature of forests and maintain it constant. reducing carbon dioxide (CO 2) in the atmosphere. (How deforestation is leading to more infectious diseases in humans.). CONTACTS: WCN, www.worldcarfree.net; EDF, www.edf.org; REDD, www.un-redd.org. This field is for validation purposes and should be left unchanged. That disruption leads to more extreme temperature swings that can be harmful to plants and animals. Such processes arent limited to tropical diseases. Yarborough morosely added: The water used to be so clear you could see the seagrass move back and forth. Forests are also cut as a result of growing urban sprawl as land is developed for homes. Any realistic plan to reduce global warming pollution sufficientlyand in timeto avoid dangerous consequences must rely in part on preserving tropical forests, reports EDF. A movement is under way to preserve existing forest ecosystems and restore lost tree cover by first reforesting (replanting trees) and ultimately rewilding (a more comprehensive mission to restore entire ecosystems). Eddie Yarborough, a leathery fishing guide who has spent the last 25 years traversing the bay for trout, redfish and snook, likens the water to chocolate milk. Deforestation is the purposeful cleaning of forest land for other uses. Whether such diseases stay confined to forest fringes or if they gain their own foothold in people, unleashing a potential pandemic, depends on their transmission, Vittor says. , The 'extreme cruelty' around the global trade in frog legs, What does cancer smell like? Can we bring a species back from the brink?, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC. Send questions to: earthtalk@emagazine.com. Obviously, Floridas native species are suffering. Rainforest is cleared for cattle farming along the Trans-Amazonian Highway. But the consequences of Floridas century-long attempt to bend the environment to its will arent hard to find. Free Trial Issue: www.emagazine.com/trial. DeSantis has outlined a major plan to rescue the Everglades. The plan would tackle local water pollution, protect springs and finish raising the Tamiami Trail, a highway that links Miami and Floridas west coast by cutting across the Everglades, to allow water to flow south to the ecosystem. Without the transpiration of trees, deforested areas become drier. When forests are wiped out, the land becomes exposed, leaving it vulnerable to being washed or blown away by elements. With nearly 17% of the forest lost already, the Amazon is currently at its tipping point. The 'extreme cruelty' around the global trade in frog legs, What does cancer smell like? We only get about a third of the water in the eastern Florida Bay that we received historically. Knowledge awaits. This Tribe Thinks So. , Excessive Use of Fertilizers and Pesticides. Deforestation has become so rapid the world all over due to demand for agricultural land, food and fuel supplies. The Global Forest Watch made it clear: protecting tropical rainforests is essential for achieving the climate goals of the Paris Agreement. 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. Hand-picked stories once a fortnight. Indeed, millions of people living in these areas depend almost entirely on agriculture and are thus extremely vulnerable to the impact of deforestation on food security, struggling to grow enough food and prevent crops from damage. Bats and agaves make tequila possibleand theyre both at risk, This empress was the most dangerous woman in Rome. Removing trees deprives the forest of portions of its canopy, which blocks the suns rays during the day and retains heat at night. All rights reserved. Dead fish in Florida following the 2018 toxic red tide. Some viruses, like Ebola or Nipah, can be transmitted directly between people, theoretically allowing them to travel around the world as long as there are humans. Conversion of forests to land used for other purposes has a long history. Farming, grazing of livestock, mining, and drilling combined account for more than half of all deforestation. Deforestation affects not only a forest and its immediate surroundings but also the atmosphere, which in turn spreads across the biosphere -- all the planet's ecosystems and everything in them. It was the first known emergence of Nipah virus in people, which has since caused a string of recurrent outbreaks across Southeast Asia. These skeletons may have the answer, Scientists are making advancements in birth controlfor men, Blood cleaning? However, the rapid destruction of forests is contributing to a decline in biodiversity never seen before. 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. For consumers, it makes sense to examine the products and meats you buy, looking for sustainably produced sources when you can. Thats like losing an area the size of Portugal every two years. Identify Priority Places: A Practitioner's Guide, Florida Vegetation 2003 and Land Use Change Between 1985-89 and 2003. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. But humans can become unwitting hosts for pathogens when they venture into or change forest habitat. , something that can have huge implications for slowing the pace of climate change and contributing to a steep rise in global temperatures. How a zoo break-in changed the life of an owl called Flaco, Naked mole rats are fertile until they die, study finds. The Everglades link to its headwater in Lake Okeechobee has been severed, with water diverted via canals for agriculture, particularly sugar. Construction of roads and buildings, logging, mining, and agricultural production have resulted in large amounts of soil erosion in the U.S. and around the world. Many factors related to cutting down trees contribute to driving species to extinction. 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. Participating nations can then accrue and sell carbon pollution credits when they can prove they have lowered deforestation below a baseline. 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. Photograph by William Daniels, Nat Geo Image Collection. 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. 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. The organization Amazon Conservation reports that destruction rose by 21 percent in 2020, a loss the size of Israel. Stopping deforestation before it reaches a critical point will play a key role in avoiding the next zoonotic pandemic. 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. 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. , Loss of Topsoil. At first pass, there seems little amiss in the idyll of Florida Bay. The FAO estimates that there are approximately 1.3 million square km (500,000 square miles) of such plantations on Earth. Populations located in the proximity of tropical forests are mostly impacted by the worsening trend. Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. These often support only very low numbers of domestic grazing animals, but they may still be considered grazing lands by national authorities. The extent to which forests have become Earths grazing lands is much more difficult to assess. Small-scale farmers clear forests by burning them and then grow crops in the soils fertilized by the ashes. The greatest deforestation is occurring in the tropics, where a wide variety of forests exists. In fact, 80% of Earths land animals and plants live in forests. (National Geographic Deforestation 1) Animals would lose shelter, food resources, and breeding area. Human population and development activities affect the rate of deforestation in biodiversity hotspots. Borrelia burgdorferi, the bacterium that causes Lyme diseaseis transmitted by ticks that rely on forest-dwelling deer to breed and obtain enough blood to survive. Omissions? Proceedings of the National Academy of Sciences. But exhaustive hunting of tropical rainforest wildlife can reduce those species necessary to To answer the question of how deforestation affects the environment, it is important to look at why humans need forests in the first place. Figure 1: Tropical primary forest loss between 2002 and 2020. Water. Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding. What are the 10 effects of deforestation? 10 Deforestation Facts You Should Know About. The effects of soil erosion go beyond the loss of fertile land. Ephemeral erosion that occurs in natural depressions. 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. In 1997, clouds of smoke hung over the rainforests of Indonesia as an area roughly the size of Pennsylvania was burned to make way for agriculture, the fires exacerbated by drought. And consumers can help stop it. To make that case, their team has been working in Malaysian Borneo to itemize the exact cost of malaria, down to each hospital bed, and syringe that doctors use. Trees are known for their capacity to absorb carbon dioxide through photosynthesis. Copyright 2023 NatureServe. Not according to biology or history. Get focused newsletters especially designed to be concise and easy to digest. Deforestation refers to the intentional clearing of forest lands for urban expansion, cattle farming, agricultural cropland, and other human purposes. While some of them move into areas occupied by other tribes, straining the lands resources, others are forced to relocate to urban settings and completely change their way of living. All rights reserved, widespread burning continues today in tropical forests, Malariawhich kills over a million annually. When deforestation occurs, temperature variates more drastically from day to night and this extreme change can often prove fatal for many animal species. Without the nourishing freshwater, the ecosystem further south has become saltier and prone to disastrous events, such as happened in 2015, when pristine water turns into a muddy slush, causing fish to flee or die. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate. Deforestation also increases the risk of uncontrollable wildfires because of humans burning vegetation. Which Teeth Are Normally Considered Anodontia? One last major effect of deforestation is its impact on food security through the loss of biodiversity. Can we bring a species back from the brink?, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC. In addition, each year fires burn an area about half as large as the areas that are cleared. How a zoo break-in changed the life of an owl called Flaco, Naked mole rats are fertile until they die, study finds. Soil in deforested areas is exposed to more sunlight, which increases the soil temperature and oxidizes the carbon in the soil to carbon dioxide. 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. for achieving the climate goals of the Paris Agreement. Environmental News, Data Analysis, Research & Policy Solutions. REDD essentially works to establish incentives for the people who care for the forest to manage it sustainably while still being able to benefit economically. One possible indirect consequence of deforestation is the spread of diseases, including those originating from birds, such as avian flu. Its a numbers game: The more we degrade and clear forest habitats, the more likely it is that were going to find ourselves in these situations where epidemics of infectious diseases occur.. According to One Tree Planted, the top five are: Industrial agriculture (Meat production) Timber logging Mining Expansion and infrastructure Climate change 75% of the US Virgin Forests Have Been Destroyed by the US Itself in the 1600s. Since the 1870s the regions forest cover has increased, though most of the trees are relatively young. Brazil is among the countries embracing REDD among other efforts to reduce carbon emissions. Studies show that, 15,3 billion trees are chopped down every year. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. For instance, forests perform important functions like: regulating weather conditions. Populations located in the proximity of tropical forests are mostly impacted by the worsening trend. In the case of the Amazon rainforest, research shows that at least 80% of its trees would be needed in order to keep the hydrological cycle going. Eroded topsoil can be transported by wind or water into streams and other waterways. DeSantis backed the plan and recently penned a letter to Trump, alongside Florida senators Scott and Marco Rubio, to ask for funding. Typically, the land produces for only a few years and then must be abandoned and new patches of forest burned. Some of the carbon dioxide released into the atmosphere comes from dead vegetation that decomposes in the ground. Can we bring a species back from the brink? Through land erosion, the soil is depleted of its nutrients, a huge source of nourishment for animals and plants. One last major effect of deforestation is its impact on food security through the loss of biodiversity. To answer the question of how deforestation affects the environment, it is important to look at why humans need forests in the first place. Updates? Heres why each season begins twice. To reduce climate change pollution produced by our current dependence on fossil fuels, renewable energy is our only economic long-term option. Deforestation alters not only nearby ecosystems -- communities of interacting organisms and their environments -- but also the atmosphere on a global level, with devastating results. 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. However, deforestation is turning these sinks into huge net emitters, something that can have huge implications for slowing the pace of climate change and contributing to a steep rise in global temperatures. Additional human activities that contribute to tropical deforestation include commercial logging and land clearing for cattle ranches and plantations of rubber trees, oil palm, and other economically valuable trees. Aggressive efforts to rewild and reforest are already showing success. Less certain are the humid tropical forests and some drier tropical woodlands that have been cleared for grazing. Obviously, Florida's native Price said this accelerating climate trend, driven by the melting of glaciers and expanding sea water, will see the Everglades retreat further north. Changing temperatures can alter which organisms can survive in an ecosystem. An iceberg melts in the waters off Antarctica. Forests around the world are home to more than, 80% of all terrestrial animal, plant, and insect species. 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. , Water. Deforestations effects reach far beyond the people and animals where trees are cut.
