Environmental Science and Sustainability MCQs (Part-3)
What is the primary cause of water scarcity?
A Excessive rainfall
B Overuse and pollution of water resources
C High water conservation efforts
D Natural water purification
Water scarcity is primarily caused by overuse and pollution of water resources. Factors like population growth, agricultural demands, industrial activities, and climate change exacerbate the problem, leading to reduced availability of clean water.
Which of the following is a key principle of sustainable agriculture?
A Monoculture farming
B Heavy use of chemical fertilizers
C Crop rotation and organic practices
D Ignoring soil health
Sustainable agriculture emphasizes crop rotation, organic practices, and soil health to maintain long-term productivity. It reduces reliance on chemical inputs, promotes biodiversity, and ensures environmental sustainability while meeting food demands.
What is the primary purpose of renewable energy?
A To deplete natural resources
B To ignore energy efficiency
C To increase pollution
D To reduce dependence on fossil fuels
Renewable energy aims to reduce dependence on fossil fuels by harnessing inexhaustible sources like solar, wind, and hydro power. It helps mitigate climate change, reduce pollution, and promote sustainable energy systems.
Which of the following is a major impact of climate change?
A Rising sea levels
B Stable weather patterns
C Decreased global temperatures
D Reduced carbon emissions
Climate change leads to rising sea levels due to the melting of polar ice caps and glaciers. It also causes extreme weather events, shifts in ecosystems, and threats to biodiversity, making it a critical global issue.
What is the primary purpose of waste segregation?
A To mix all types of waste
B To increase landfill use
C To facilitate recycling and proper disposal
D To ignore waste management
Waste segregation involves separating waste into categories like recyclables, organic, and hazardous materials. It facilitates recycling, reduces landfill use, and ensures proper disposal, contributing to efficient waste management.
Which of the following is a key principle of eco-friendly transportation?
A Using fossil fuel-powered vehicles
B Ignoring air quality
C Increasing traffic congestion
D Promoting public transportation and cycling
Eco-friendly transportation focuses on promoting public transportation, cycling, and electric vehicles to reduce emissions, traffic congestion, and reliance on fossil fuels. It aims to create sustainable and efficient mobility systems.
What is the primary cause of groundwater contamination?
A Natural filtration
B Rainwater harvesting
C Industrial and agricultural pollutants
D Soil conservation
Groundwater contamination is primarily caused by industrial and agricultural pollutants, such as chemicals, pesticides, and heavy metals. These contaminants seep into the ground, making groundwater unsafe for drinking and irrigation.
Which of the following is a key principle of sustainable tourism?
A Overcrowding tourist destinations
B Minimizing environmental impact
C Ignoring local cultures
D Increasing pollution
Sustainable tourism focuses on minimizing environmental impact, preserving local cultures, and supporting community development. It promotes responsible travel practices that benefit both the environment and local populations.
What is the primary purpose of environmental education?
A To raise awareness and promote sustainable practices
B To ignore environmental issues
C To increase pollution
D To deplete natural resources
Environmental education aims to raise awareness about environmental issues and promote sustainable practices. It empowers individuals and communities to take action for environmental conservation and sustainable development.
Which of the following is a major cause of air pollution in urban areas?
A Vehicle emissions
B Tree planting
C Renewable energy
D Water conservation
Vehicle emissions are a major cause of air pollution in urban areas, releasing pollutants like nitrogen oxides, carbon monoxide, and particulate matter. These emissions contribute to smog, respiratory diseases, and climate change.
What is the primary purpose of a carbon footprint assessment?
A To increase carbon emissions
B To measure and reduce greenhouse gas emissions
C To ignore climate change
D To promote fossil fuel use
A carbon footprint assessment measures the total greenhouse gas emissions caused by an individual, organization, or product. It helps identify opportunities to reduce emissions and mitigate climate change impacts.
Which of the following is a key principle of sustainable water management?
A Over-extraction of groundwater
B Efficient use and conservation of water resources
C Ignoring water pollution
D Increasing water wastage
Sustainable water management focuses on the efficient use and conservation of water resources to ensure long-term availability. It includes practices like rainwater harvesting, reducing water wastage, and treating wastewater to minimize environmental impact.
What is the primary cause of soil degradation?
A Overuse of chemical fertilizers
B Crop rotation
C Organic farming
D Soil conservation
Soil degradation is primarily caused by the overuse of chemical fertilizers, pesticides, and poor agricultural practices. These practices deplete soil nutrients, reduce fertility, and lead to erosion, making it difficult to sustain agricultural productivity.
Which of the following is a key principle of green building design?
A High energy consumption
B Use of non-renewable materials
C Energy efficiency and sustainability
D Ignoring water conservation
Green building design emphasizes energy efficiency, sustainability, and the use of renewable materials. It aims to reduce the environmental impact of buildings by incorporating features like solar panels, efficient insulation, and water-saving technologies.
What is the primary purpose of an environmental audit?
A To ignore environmental regulations
B To deplete natural resources
C To increase pollution
D To assess and improve environmental performance
An environmental audit is a systematic evaluation of an organization’s environmental performance. It identifies areas for improvement, ensures compliance with environmental regulations, and promotes sustainable practices to reduce environmental impact.
