Eggshell thinning

Definition

Eggshell thinning refers to the process where the shells of bird eggs become thinner due to exposure to certain chemicals or pollutants. This can lead to reduced hatching success and population decline in affected bird species.

Analogy

Think of eggshells as protective armor for baby birds inside their eggs. When eggshells become thin due to harmful substances like pesticides or pollutants, it's like having weakened armor that makes it easier for predators or external factors to harm them.
