Discuss the effects of deforestation on the following environment

Deforestation Monitoring and Management Forests cover almost a third of all land area on Earth, yet at a current deforestation rate, in the nearest future we might lose most to all of it. Trees play an essential role in the carbon cycle, absorbing CO2 and giving off oxygen, thus keeping global temperatures from rising rapidly, and providing air to breathe for all living beings on the planet. Over two thirds of all land animals rely on forests as their habitats. The effects of deforestation on environment can be catastrophic, if humans do not take up sustainable management of forest resources and agriculture. Monitoring forests in near-real time is one of key solutions for deforestation. Forest fires Fire causes more deforestation annually than logging and agriculture combined. This is mostly due to human intervention in the natural fire cycle. While some forest ecosystems have evolved to use fire to their advantage, other areas are less adapted. When human activities cause fire in such unprepared forest areas, the results can be catastrophic. In addition, humanly-induced forest fires are usually more frequent and more intense than their natural counterpart. All of this leads to a significant increase in global forest loss each year. Pests & Diseases Pests and diseases are among the most inconspicuous causes of deforestation. Yet, in recent years, pest infestations and tree diseases have become more common due to increase in international plant trade. When trees encounter n...

(What happens due to deforestation) Increase in Temperature and Global Warming We know that Plants and trees consume carbon dioxide and give out oxygen during photosynthesis. If there are no trees, it will lead to more carbon dioxide in the atmosphere This Carbon Dioxide trap heat rays from sun. This will lead to increase in temperature of earth and can cause global warming Increase in Pollution We know that carbon dioxide is generated by industries and vehicles. Plants and trees consume this carbon dioxide and help in reducing pollution If we cut trees, it will increase carbon dioxide in the atmosphere Increase in Droughts Removal of trees also disturbs water cycle and cause droughts (less rainfall) Roots of tree suck water from earth’s surface This water goes to the leaves. Due to sun,this water gets evaporated and goes to clouds This later fall down as rain If there are less trees,less water will go up bringing less rain Desertification Roots of trees bind soil together Due to less trees,there will be more soil erosion(fertile soil is eroded by wind and water).Hence fertile lands will soon turn into deserts Animal and Plant Life is Affected Animals and Birds are dependent on plants and trees for their food. Natural Habitat (living area) of wild animals and plants is disturbed. In case of deforestation,there will be less forests,so these plants and animals will become extinct (die because of shortage of food ) Shortage of Food and Forest Produce Trees and plants in fores...

Effects of deforestation on the environment: Plants absorb CO 2from the atmosphere to perform photosynthesis. If plants are destroyed, then the level of CO 2in the atmosphere will rise. As a result, CO 2will trap more heat radiations, thereby adding to global warming. An increase in the temperature of the Earth will disturb the natural water cycle. As a result, there will be a change in the rainfall pattern. This could lead to floods or droughts

Activity : 2 hrs 30 mins Activity : 2 hrs 30 mins Local and Global Effects of Deforestation in the Amazon Rain Forest Local and Global Effects of Deforestation in the Amazon Rain Forest Students analyze a map to identify and describe multiple landscapes in the Amazon rain forest, the organisms that inhabit those landscapes, and the role of the forest in the water cycle and nutrient cycle. Then they construct a scientific argument for the effects of deforestation on the local ecosystem and the water and nutrient cycles. 1. Activate students’ prior knowledge about the local and global environmental effects of deforestation. Introduce the activity with a discussion about students’ local area and the organisms that live there. Ask students to brainstorm what roles trees might play in the forest. Then have students brainstorm consequences to the plants and animals that inhabit the local ecosystem if all the trees were removed. Introduce the term deforestation and share that deforestation is of major concern in the Amazon rain forest. Ask the guiding question: How does deforestation in the Amazon rain forest affect the water cycle, nutrient cycle, and plant and animal life? Facilitate a whole-class discussion around the Habitat Loss inset map with a focus on Deforestation on the Amazonia: The Human Impact side of the map. Explain to students that they will explore the layers of forest and different organisms that live there along with the role trees play in the nutrient and wate...

Deforestation has important global consequences. Forests see see In addition, most of the planet’s valuable On a more local scale, the effects of In the tropics, much of the deforested land exists in the form of steep mountain hillsides. The combination of steep slopes, high rainfall, and the lack of tree roots to bind the Although forests may regrow after being cleared and then abandoned, this is not always the case, especially if the remaining forests are highly fragmented. Such habitat fragmentation isolates populations of plant and animal species from each other, making it difficult to reproduce without genetic bottlenecks, and the fragments may be too small to support large or territorial animals. Furthermore, deforested lands that are planted with commercially important

Forests cover 31% of the land area on our planet. They help people thrive and survive by, for example, purifying water and air and providing people with jobs; some 13.2 million people across the world have a job in the forest sector and another 41 million have a job that is related to the sector. Many animals also rely on forests. Forests are home to more than three-quarters of the world’s life on land. Forests also play a critical role in mitigating climate change because they act as a carbon sink—soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns. But forests around the world are under threat, jeopardizing these benefits. The threats manifest themselves in the form of deforestation and forest degradation. The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging. In 2019, the tropics lost close to 30 soccer fields' worth of trees every single minute. Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world’s biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. Deforestation in this region is particularly rampant near more populated areas, roads and rivers, but even remote areas have been encroached upon when valuable mahogany, g...
