Biodiversity refers to the variety of living organisms, including plants, animals, and microorganisms, as well as the ecosystems in which they exist. Biodiversity plays a critical role in supporting sustainable development for several reasons:
Biodiversity provides essential ecosystem services that contribute to human well-being. These services include the provision of food, clean water, air purification, climate regulation, pollination, nutrient cycling, and soil fertility. These services are vital for sustaining human life and economic activities.
Biodiversity forms the basis of many economic sectors, including agriculture, forestry, fisheries, and tourism. These sectors rely on healthy ecosystems and diverse species to provide resources and economic opportunities. Biodiversity loss can have significant negative impacts on these sectors and local communities' livelihoods.
Biodiversity enhances the resilience of ecosystems and communities to environmental changes and shocks. Diverse ecosystems are more resilient to disturbances such as climate change, disease outbreaks, and natural disasters. Protecting and restoring biodiversity can help communities adapt to environmental challenges and maintain their well-being. Biodiversity is an integral part of cultural heritage and provides aesthetic and recreational benefits. Many cultures have strong connections to their local biodiversity and traditional knowledge systems associated with nature. Biodiversity also enhances the beauty and enjoyment of natural spaces, contributing to people's quality of life.
Therefore, the reason provided correctly explains why biodiversity conservation is crucial for sustainable development. Biodiversity's contribution to ecosystem services and human well-being highlights the importance of protecting and conserving biodiversity to achieve sustainable development goals.
Question : Assertion: Forest conservation is essential for maintaining ecological balance and supporting sustainable development.
Reason: Forests provide numerous ecosystem services, such as carbon sequestration, water regulation, and biodiversity conservation.
Question : Assertion: Forest conservation plays a crucial role in sustainable development as forests provide numerous ecosystem services, including carbon sequestration and biodiversity preservation.
Reason: Deforestation leads to environmental degradation, loss of biodiversity, and contributes to climate change.
Question : Assertion: Biodiversity conservation is essential for sustainable development as it ensures the stability and resilience of ecosystems.
Reason: Biodiversity loss can disrupt ecosystem functions, negatively impacting human well-being and the environment.
Question : Assertion: Ecosystem restoration is vital for sustainable development as it helps to revive degraded ecosystems and enhance their capacity to provide essential services.
Reason: Degraded ecosystems are less resilient and less capable of supporting biodiversity and providing ecosystem services.
Question : Assertion: Land degradation is a significant environmental challenge that hinders sustainable development.
Reason: Land degradation reduces agricultural productivity, biodiversity, and ecosystem services.
