Read the following excerpt from a newspaper article about the effects of humans on wild animals.
Humans are driving mammals including deer, tigers and bears to hide under the cover of darkness, jeopardising the health of the creatures that are only supposed to be active by day, new research his found. The presence of people can instil strong feelings of fear in animals and as human activities now cover 75 per cent of the land, we are becoming increasingly harder to avoid. Unable to escape during the day, mammals are forced to emerge during the night.
A team led by Kaitlyn Gaynor at the University of California, Berkeley arrived at this conclusion after analysing nearly 80 studies from six continents that monitored the activity of various mammals using GPS trackers and motion-activated cameras. The scientists used this data to assess the night time antics of the animals during periods of low and high human disturbance.
Such disturbances ranged from relatively harmless activities like hiking to overtly destructive ones like hunting, as well as larger scale problems like farming and road construction. Overall, the researchers concluded that from beavers to lions, there was an increase in nocturnal behaviour when humans were in the vicinity.
