The natural cycle of life and death helps maintain genetic diversity and a strong gene pool. Trapping is indiscriminate. Trapped mothers are killed, leaving litters to die. Many traps are set on or in creeks to kill by drowning, and some animals suffer for up to 20 minutes under water. Young animals are killed. Old or sick animals may survive instead of young and healthy, since the healthier animals spend more time foraging and thus cover more ground and are more like to encounter a trap. Trapping does not balance nature; it upsets the balance. There is nothing humane about trapping.
