Air Pollution
What are two major sources of air pollution caused by human activities?
burning fossil fuels and industrial emissions
Name two common sources of water pollution caused by human activities.
industrial waste and agricultural runoff
How does deforestation contribute to climate change?
reducing the number of trees that absorb carbon dioxide
What is the primary greenhouse gas responsible for climate change?
carbon dioxide (CO₂)
Name one renewable energy source that can replace fossil fuels.
solar energy, wind power, or hydroelectric power
What is the main gas responsible for the greenhouse effect
carbon dioxide (CO₂)
What is the name of the process where excess nutrients in water bodies lead to algae overgrowth and oxygen depletion?
eutrophication
What is the term for the long-term removal of trees for farming, urbanization, or logging?
deforestation
What is the largest human-caused source of air pollution?
he burning of fossil fuels for energy production (coal, oil, and gas power plants)
What are two ways individuals can reduce their plastic waste
using reusable bags and water bottles, and avoiding single-use plastics
What is the name for a type of rain that results from pollutants like sulfur dioxide and nitrogen oxides mixing with water in the atmosphere?
acid rain
This term describes the contamination of land by hazardous chemicals, pesticides, and improper waste disposal.
soil pollution
What is a major negative effect of soil pollution on human health?
contaminated crops that can lead to food poisoning and long-term health issues
What is a primary reason deforestation occurs in the Amazon rainforest?
clearing land for agriculture, cattle ranching, and logging
What is one method cities can use to reduce air pollution from transportation?
investing in public transportation, bike lanes, or electric vehicle incentives
Which type of pollution occurs when city lights prevent people from seeing stars at night?
light pollution
What are two negative impacts of overuse of pesticides in farming?
pollution of soil and water, and harm to beneficial insects and wildlife
Which farming practices contribute to soil erosion and pollution?
deforestation, excessive pesticide use, and overgrazing
Which industry is the largest contributor to ocean plastic pollution?
the fishing industry (due to discarded nets and plastic waste)
What is an international agreement aimed at reducing carbon emissions to fight climate change
Paris Agreement
Name three major health effects of air pollution on humans.
lung diseases (such as asthma or bronchitis), heart disease, and increased risk of strokes
What is the primary cause of ocean acidification, and what are two consequences for marine life?
increased carbon dioxide (CO₂) emissions dissolving into seawater
Consequences: coral bleaching and weaker shells in marine animals like clams and corals
Name two types of pollutants that contribute to soil degradation and their sources.
pesticides from agriculture and heavy metals from industrial waste
What is the connection between industrial pollution and acid rain?
industrial emissions release sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), which react with water in the atmosphere to form acid rain
What are three policies or actions governments can implement to reduce pollution?
carbon taxes, stricter environmental regulations on industries, and investment in renewable energy
