deforestation.pptx measures and its causes

Afforestation has both positive and negative environmental impacts. While it increases oxygen production through photosynthesis, it can also harm animal habitats. Some scientists have found that afforestation disrupts vital biotic and abiotic factors that many species depend on, such as water, carbon dioxide, and nitrogen. However, trees do play an important role in sequestering carbon and reducing greenhouse gases. The full impacts of afforestation programs over the past century require more research to fully understand their costs and benefits.

The document discusses environmental issues related to natural resources like forests and water. It provides definitions of environment and discusses the scope of environmental science. It then describes the major uses and ecological importance of forests, as well as causes and impacts of deforestation such as loss of biodiversity and soil erosion. Specific case studies on desertification and disappearing tea gardens are mentioned. Impacts of mining, dams, and water resources are also summarized. The document stresses the need for public awareness and participation to properly address environmental problems.

Forests and Minerals are important part of natural resources. Their uses and conservation must be taught at many levels of education.

The document discusses several key environmental issues: 1) Sustainable development aims to meet present needs without compromising the future, while ecological footprints measure countries' impacts on resources. 2) Fresh water scarcity is exacerbated by overuse polluting rivers and draining aquifers, though solutions like water restrictions aim to conserve supplies. 3) The ozone layer is depleted by chemicals like CFCs, though the Montreal Protocol phased them out, while the greenhouse effect from CO2 emissions is exacerbated by fossil fuel use and deforestation contributes to global warming and biodiversity loss.

The document discusses deforestation, including its causes, effects, extent in India, and methods for control. It defines deforestation as the removal of forests and notes its main drivers are shifting agriculture, commercial logging, mining and dams. Deforestation leads to soil erosion, decreased rainfall, loss of biodiversity and plants used in medicine. India has lost over 3 million hectares since 1951 mainly due to population growth, development and dependency on forests. Reforestation efforts, legislation, wildlife sanctuaries and sustainable forest management can help control deforestation.

Forests play an important role in carbon storage and climate change. While deforestation reduces carbon sinks, sustainable forest management and reforestation can increase carbon sequestration. However, deforestation continues due to logging and land conversion for agriculture. The paper industry both contributes to deforestation but also promotes certification and sustainable practices to reduce its environmental impact. Debate exists around whether certain forestry and paper production methods can be considered carbon neutral.

This document defines and discusses deforestation. It begins by noting that forests cover 31% of land and provide vital benefits like oxygen, habitat, food, water and medicine for over 1.6 billion people. Deforestation is then defined as the removal of forests to convert land to non-forest use, like agriculture. The main causes of deforestation are clearing land for housing and agriculture as well as logging, mining and dams. The effects include increased erosion, disrupted water cycles, reduced biodiversity, economic impacts and climate change through greenhouse gas emissions. Solutions proposed are policies limiting deforestation, reforestation, supporting anti-deforestation groups, reducing paper usage and educating others.

Deforestation, clearance or clearing is the removal of a forest. • Examples of deforestation include conversion of forestland to farms, ranches, or urban use. By, Ariful Islam (arif) 5th semester Botany department Goalpara College,Goalpara

Global warming is being driven by human activities that release greenhouse gases like carbon dioxide and methane into the atmosphere. The top causes are burning fossil fuels for energy, deforestation, and industrial processes. This is leading to rising global temperatures which cause extreme weather, melting ice and sea level rise, and disrupted ecosystems. To address it, we must transition to renewable energy, plant more trees, use sustainable agriculture, and cooperate internationally on emissions reductions and adaptation efforts. Urgent action is needed to curb emissions and build resilience to the climate changes already underway.

Deforestation has several negative effects: 1) It contributes to climate change and global warming by reducing forests that absorb carbon dioxide. 2) It increases greenhouse gas emissions as trees are cut down and no longer absorbing emissions. 3) It causes soil erosion as tree roots no longer hold soil in place, exposing it to runoff into waterways.
