Are shark attacks becoming more common?
Long-term trends in the prevalence of shark-human interactions are directly correlated to human population and interest in marine recreation. Because more humans are spending more time in the ocean, the number of shark-human interactions and other marine-related injuries is generally increasing. Increased media coverage and scientific interest has also led to an increase in the number of shark-human interactions that are recorded. Sharp declines in shark populations during recent decades in many areas of the world as a result of over-fishing and habitat loss are reducing the potential for shark-human interactions. Local year-to-year variations in economic and social factors, weather, and ocean conditions significantly influence the abundance of sharks and humans in the water. As a result, short-term changes in the number of shark attacks—up or down—must be viewed with caution. Scientists prefer to view trends over longer periods of time (e.g., by decade) rather than trying to assign un
