Greenhouse Effect as a Consequence of Deforestation
Deforestation has severe consequences on the environment, one of which is the exacerbation of the greenhouse effect. This phenomenon is a result of the accumulation of greenhouse gases in the Earth's atmosphere, leading to the trapping of heat and causing global warming.

Impact of Deforestation on the Greenhouse Effect:
- Reduced Carbon Sequestration: Trees play a crucial role in absorbing carbon dioxide from the atmosphere through the process of photosynthesis. Deforestation leads to a decrease in the number of trees, resulting in less carbon dioxide being removed from the air.
- Increased Greenhouse Gas Emissions: When forests are cleared or burned, they release the stored carbon back into the atmosphere in the form of carbon dioxide. This contributes to the increasing levels of greenhouse gases in the atmosphere.
- Loss of Biodiversity: Deforestation not only reduces the number of trees that can absorb carbon dioxide but also destroys habitats for various plant and animal species. This loss of biodiversity can disrupt ecosystems and further contribute to the greenhouse effect.
- Altered Climate Patterns: The greenhouse effect caused by deforestation can lead to changes in climate patterns, such as rising temperatures, erratic weather conditions, and sea level rise. These changes have far-reaching impacts on both the environment and human populations.
- Feedback Loop: Deforestation and the resulting greenhouse effect create a dangerous feedback loop. As temperatures rise due to increased greenhouse gas emissions, forests become more vulnerable to wildfires and other destructive events, further accelerating deforestation.
In conclusion, deforestation significantly contributes to the greenhouse effect by reducing carbon sequestration, increasing greenhouse gas emissions, disrupting ecosystems, altering climate patterns, and creating a harmful feedback loop. It is essential to address deforestation to mitigate the impacts of the greenhouse effect and combat climate change.

Passage-1 ‘Desertification’ is a term used to explain a process of decline in the biological productivity of an ecosystem, leading to total loss of productivity. While this phenomenon is often linked to the arid, semi-arid and sub-humid ecosystems, even in the humid tropics, the impact could be most dramatic. Impoverishment of human-impacted terrestrial ecosystems may exhibit itself in a variety of ways : accelerated erosion as in the mountain regions of the country, salinization of land as in the semi-arid and arid ‘green revolution’ areas of the country, e.g., Haryana and western Uttar Pradesh, and site quality decline—a common phenomenon due to general decline in tree cover and monotonous monoculture of rice/wheat across the Indian plains. A major consequence of deforestation is that it relates to adverse alterations in the hydrology and related soil and nutrient losses. The consequences of deforestation invariably arise out of site degradation through erosive losses. Tropical Asia, Africa and South America have the highest levels of erosion. The already high rates for the tropics are increasing at an alarming rate (e.g., through the major river systems— Ganga and Brahmaputra, in thecontext), due to deforestation and land management practices subsequent to forest clearing. In the mountain context, the declining moisture retention of the mountain soils, drying up of the ‘underground springs and smaller rivers in the Himalayan could be attributed to drastic changes the forest cover. An indirect consequence is drastic alteration in the uplandlowland interaction, mediated through water. The current concern the tea planter of Assam has is about the damage to tea plantations due to frequent inundation along the flood-plains of Brahmaputra, and the damage to tea plantation and the consequent loss in tea productivity is due to rising level of the river bottom because of siltation and the changing course of the river system. The ultimate consequences of site desertification are soil degradation, alteration in available water’ and its quality, and the consequent decline in food, fodder and fuelwood yields essential for the economic wellbeing of rural communities.=>According to the passage, which of the following are the consequences of decline in forest cover?1. Loss of topsoil2. Loss of smaller rivers3. Adverse effect on production4. Declining of groundwater.Q. Select the correct answer using the code given below.
