CONCEPT Environmentalism 17 “Threats of an epidemic haunt citizens as the number of unvaccinated children continue to grow. People are frightened of the implications and angry that a few have placed so many at risk.” Choose the most likely source for this quotation. ● A politician, because the statements are general and may be biased ● The media, because the language is controversial and sensationalistic ● A scientist, because the language is non-technical so that others will understand ● A scientific journal, because it has been peer-reviewed and verified CONCEPT Scientific Literacy 18 Ecosystems provide many benefits to humans, which are termed "ecosystem services."Visiting the Grand Canyon on a school field trip is an example of a __________ service that ecosystems can provide. ● supporting ● provisioning ● cultural ● regulating CONCEPT Biodiversity 19 Choose the statement that does NOT accurately describe the environmental impacts of population growth. ● More energy is needed, which leads to over-reliance on freshwater systems, which leads to water pollution. ● More land is needed, which leads to habitat damage, which leads to loss of ecosystems. ● More energy is needed, which leads to burning of non-renewable natural resources, which leads to their depletion. ● More land is needed, which leads to deforestation, which leads to less oxygen in the atmosphere.
