avoid bumping into blind cheetahs

“Namibia is under invasion by multiplying armies of thorny trees and bushes, which are spreading across its landscape and smothering its grasslands. Conservationists have found starving cheetahs that lost their sight after streaking through bush encroached habitats in pursuit of fleet footed food

….an emerging body of science indicates that rapidly increasing atmospheric carbon dioxide may be boosting the onrushing waves of woody vegetation. Are blind, starving cheetahs useful symbols of climate change? You decide.”
