How Many Rats Are Left in the World?
WouterThe question of how many rats are left in the world is a difficult one to answer. Although there are no exact numbers, rodent experts can give estimates based on data from surveys. Rats can reproduce rapidly, and under ideal conditions, they can produce up to 15,000 offspring in a single year. However, as the population grows, breeding rates begin to decrease dramatically.
The number of rats in the world has been estimated at around seven billion animals worldwide. In Britain alone, there are approximately 1.0 to 1.5 billion rats. These animals are very social and have important roles in the family system. It is also estimated that as of 1950, there were 2,000 rats per square kilometer in the sewers.
In Canada, authorities have taken several steps to combat the problem. Preventative measures include geo-tagging property, focusing on structural integrity and educating city employees. They also warn residents to look out for signs of the creatures. In some places, authorities have imposed a controversial plan aimed at curtailing rat populations.
Rats can be found throughout the world, although they tend to be most commonly found in sewers and homes. They have numerous predators, including cats and snakes. Birds of prey also target rodents. They can also cannibalize other rats, causing their numbers to decrease.
