Question

drag the tiles to the correct boxes to complete the pairs. four examples of the effects of environmental change are given. match each one with the type of environmental change it demonstrates. natural disasters disease human exploitation climate change african forest elephants have been hunted to near extinction levels to obtain ivory. the eruption of mount saint helens destroyed some populations of conifers. increasing global temperatures have altered migration patterns of humpback whales. an infection with a fungus reduced the population of north american elm trees.

Explanation:

• "African forest elephants have been hunted to near extinction levels to obtain ivory" is an example of human exploitation as humans are over - harvesting elephants for their tusks.
• "The eruption of Mount Saint Helens destroyed some populations of conifers" is a natural disaster as it is a geological event causing destruction.
• "Increasing global temperatures have altered migration patterns of humpback whales" is a result of climate change as the change in temperature (a climate - related factor) affects the whales' behavior.
• "An infection with a fungus reduced the population of North American elm trees" is a disease - related environmental change as a fungal pathogen is the cause of the population decline.

Answer:

• African forest elephants have been hunted to near extinction levels to obtain ivory: human exploitation
• The eruption of Mount Saint Helens destroyed some populations of conifers: natural disasters
• Increasing global temperatures have altered migration patterns of humpback whales: climate change
• An infection with a fungus reduced the population of North American elm trees: disease
