This gas, released by burning fossil fuels, is the main contributor to global warming.
What is carbon dioxide (CO2)?
This pollutant was banned by the Montreal Protocol to protect the ozone layer.
What are chlorofluorocarbons (CFCs)?
As atmospheric CO₂ increases, the pH of the oceans does this.
What is decrease (becomes more acidic)?
This is the term for the variety of life in an area.
What is biodiversity?
This global process is driven by industrialization, agriculture, and urban expansion.
What is globalization?
This protocol signed, signed in 1997, aimed to reduce global greenhouse gas emissions.
What is the Kyoto Protocol?
This layer of the atmosphere contains the ozone layer.
What is the stratosphere?
Ocean acidification threatens marine organisms that rely on this mineral for their shells.
What is calcium carbonate?
This is one of the leading causes of habitat loss and species extinction.
What is deforestation / land use change?
Overfishing leads to a collapse of this.
What is fish populations / fisheries?
Melting permafrost released this potent greenhouse gas
What is methane (CH4)?
This environmental issue results from thinning of the ozone layer.
What is increased UV radiation exposure / skin cancer?
Coral bleaching is primarily caused by this environmental change.
What is rising ocean temperatures?
The Endangered Species Act was passed in this country.
What is the United States?
This type of farming leads to the most habitat destruction globally.
What is industrial agriculture?
Name one human activity that increases atmospheric CO2 levels
What is deforestation/burning fossil fuels?
Unlike stratospheric ozone, ground-level ozone is considered this.
What is a pollutant?
This term describes the decrease in dissolved oxygen levels in aquatic ecosystems.
What is hypoxia?
This term refers to the disappearance of a species from a particular area, even though it still exists elsewhere.
What is local extinction?
This is the term for species transported and established outside their native range.
What are invasive species?
This effect is the natural process by which greenhouse gases trap heat in Earth's atmosphere.
What is the greenhouse effect?
Ozone depletion is most severe over this region.
What is Antarctica?
This is the term for species like lionfish or zebra mussels that disrupt ocean ecosystems.
What are invasive species?
This theory explains why larger habitats support more species.
What is island biogeography theory?
This describes the increase in human populations moving into wild areas, reducing biodiversity.
What is habitat fragmentation?
