Section A

Q1) Why ecological significance of forest is more important in present day context? Explain.

The ecological significance of forests is increasingly important in the present day context for several reasons, as forests play a crucial role in maintaining the overall health of the planet. Here are some key reasons why the ecological significance of forests is particularly important today:

Biodiversity Conservation: Forests are home to a vast array of plant and animal species, many of which are not found anywhere else. The rich biodiversity in forests contributes to ecosystem stability and resilience. In the face of climate change and habitat destruction, preserving biodiversity becomes critical for the survival of various species, including those essential for maintaining ecosystem balance.

Climate Regulation: Forests act as carbon sinks, absorbing carbon dioxide during photosynthesis and storing carbon in trees and soil. This helps mitigate climate change by reducing the concentration of greenhouse gases in the atmosphere. Deforestation and forest degradation contribute significantly to the release of stored carbon, exacerbating global warming.

Water Cycle Regulation: Forests play a vital role in regulating the water cycle. Trees absorb water from the soil and release it through a process called transpiration. This contributes to the formation of clouds and precipitation. Deforestation disrupts this cycle, leading to altered rainfall patterns, increased runoff, and a higher risk of floods and droughts.

Soil Conservation: The roots of trees help bind soil particles together, preventing erosion. Forests act as natural barriers against soil degradation, maintaining soil fertility and preventing landslides. Deforestation can result in soil erosion, loss of topsoil, and increased vulnerability to natural disasters.

Human Livelihoods: Many communities around the world depend on forests for their livelihoods. Forests provide resources such as timber, non-timber forest products, and medicinal plants. Sustainable management of forests can support local economies and provide a source of income for communities.

Air Quality Improvement: Forests release oxygen as a byproduct of photosynthesis, contributing to cleaner air. The reduction of forested areas can lead to decreased oxygen production and increased air pollution, impacting human and animal health.

Cultural and Recreational Value: Forests have cultural significance for many communities and indigenous groups. They often hold spiritual and traditional value. Additionally, forests provide recreational opportunities and contribute to the overall well-being of people by offering spaces for outdoor activities.

Global Ecosystem Connectivity: Forests connect different ecosystems and provide corridors for the movement of species. This connectivity is crucial for maintaining genetic diversity and allowing species to adapt to changing environmental conditions.

In the present day, with growing concerns about climate change, loss of biodiversity, and the need for sustainable development, recognizing and preserving the ecological significance of forests is paramount. Global efforts are underway to promote responsible forestry practices, reforestation, and conservation initiatives to ensure the long-term health and resilience of forest ecosystems.

Q2) Answer the following questions in about 125 words each.

a) Explain the characteristics of Western Ghats for inclusion as Biodiversity hotspots.

d) What is Disposal of waste? Why segregation of waste is needed?

3) Explain the human-environment relationship by taking examples of biotic and abiotic components?

Q4) “As humans civilisation progressed, man started altering the environment in the pursuit of creating an economic, social and cultural environment of his own choice. This slowly resulted in the depletion of natural resources and degradation of environment.” Explain it in context of national legislations of water acts?

Q5) “Biosphere reserves are internationally recognised areas established to promote and demonstrate a balanced relationship between Humans and the Biosphere.” Elaborate this statement in the context of conservation of nature?
