Habitat destruction additionally poses a major risk, as coastal improvement and air pollution degrade their most well-liked searching grounds and breeding areas. Local weather change can be rising as a possible risk, altering ocean temperatures and disrupting their prey populations.
Fortunately, conservation efforts are underway to guard nice white sharks. Many international locations have applied fishing rules to restrict or prohibit the seize of those sharks. Marine protected areas have been established in key habitats to safeguard their feeding grounds and breeding websites.
