Climate Change
This effect happens when greenhouse gases trap heat in Earth’s atmosphere and warm the planet.
What is the greenhouse effect?
This material is commonly used once and thrown away, making it a major source of pollution.
What is plastic?
This type of energy comes from sources that naturally replenish, like sunlight and wind.
What is renewable energy?
This part of a sporting event often creates the most waste due to food packaging, cups, and utensils.
What is game day concessions?
This instrument has 88 keys.
What is the piano?
This gas is the main greenhouse gas emitted by human activities and is measured in “ppm.”
What is carbon dioxide (CO₂)?
This term describes waste that can be reused or processed into new products instead of being sent to a landfill.
What is recycling?
This renewable energy source currently produces the most electricity worldwide.
What is hydropower?
This game-day item is a major source of waste at sporting events and is often single-use.
What are plastic cups and bottles?
California Memorial Stadium is uniquely built directly on this major geological fault.
What is the Hayward Fault?
Climate change increases the frequency and intensity of these events by raising global average temperatures.
What are heat waves?
Only about this percentage of plastic waste is recycled globally.
What is about 9 percent?
Improving energy efficiency reduces emissions mainly because it lowers demand for this.
What is energy from fossil fuels?
Team travel contributes to emissions mainly because most professional and college teams rely on this mode of transportation.
What is air travel?
This ocean is the largest on Earth by surface area.
What is the Pacific Ocean?
Since the early 1900s, global mean sea level has risen by about this amount? (in meters or centimeters)
What is about 0.20 meters (20 cm)?
This process causes harmful chemicals from landfills or waste sites to seep into soil and groundwater.
What is leaching?
This tradeoff occurs when renewable energy projects reduce emissions but disrupt local ecosystems or communities.
What is a land-use tradeoff?
Installing LED stadium lighting reduces environmental impact primarily because it lowers this.
What is energy use and electricity demand?
Octopuses have this many hearts.
What is three?
In the United States, this sector is the largest source of direct greenhouse gas emissions.
What is transportation?
When waste decomposes in landfills without oxygen, it produces this potent greenhouse gas.
What is methane?
Extracting fossil fuels and minerals can permanently damage ecosystems through this process, which removes vegetation and topsoil.
What is strip mining?
This tradeoff occurs when building new stadiums improves efficiency but increases emissions from construction materials like concrete and steel.
What is embodied carbon?
California Memorial Stadium officially opened in this year.
What is 1923?
