Air pollution is the presence of harmful substances in the atmosphere, primarily from vehicle emissions, industrial discharges, and burning fossil fuels.
What is the impact of water pollution on ecosystems?
Water pollution affects ecosystems by introducing toxins, decreasing oxygen levels, and disrupting the balance, harming aquatic life and spreading diseases.
How does plastic waste affect the environment?
Plastic waste contributes to pollution, harms wildlife through ingestion and entanglement, and takes centuries to decompose, persisting in ecosystems.
What are the consequences of soil erosion?
Soil erosion leads to loss of fertile land, reduced agricultural productivity, sedimentation in waterways, and destruction of habitats.
What is overfishing and its impact on marine ecosystems?
Overfishing is the depletion of fish stocks beyond sustainable levels, leading to the collapse of fish populations and disruption of marine ecosystems.
What are fossil fuels, and why are they unsustainable?
Fossil fuels, such as coal, oil, and natural gas, are unsustainable because they are non-renewable and their combustion releases large amounts of greenhouse gases.
How does mining impact the environment?
Mining impacts the environment through habitat destruction, soil and water pollution, and increased erosion.
How is noise pollution problematic for both humans and wildlife?
Noise pollution can lead to stress and hearing loss in humans, disrupt communication in wildlife, and interfere with natural behaviors.
What are non-renewable resources, and why are they at risk?
Non-renewable resources, like fossil fuels and minerals, are at risk of depletion because they take millions of years to form and are being rapidly consumed.
How does excessive groundwater extraction affect the environment?
Excessive groundwater extraction can lead to land subsidence, reduced water availability, and degradation of ecosystems dependent on water tables.
What is meant by 'The Tragedy of the Commons' in environmental science?
'The Tragedy of the Commons' describes how individuals, acting in their own interest, deplete common resources, leading to their eventual destruction.
Why is reducing consumption important for the environment?
Reducing consumption is important to conserve resources, reduce waste and pollution, and minimize environmental impact.
How can reducing meat consumption benefit the environment?
Reducing meat consumption decreases greenhouse gas emissions, conserves water and land, and reduces biodiversity loss from agriculture expansion.
What are alternative energy sources to fossil fuels?
Alternative energy sources like solar, wind, hydroelectric, and geothermal energy provide renewable, low-emission alternatives to fossil fuels.
Why is water conservation crucial in modern times?
Water conservation is crucial to ensure available supply for future needs, protect ecosystems, and reduce energy use in treatment processes.
