Biodiversity and Conservation: common misconceptions

If your child says… “Biodiversity means counting species.”

Ask together

Would listing rice once record the inherited differences between its varieties?

What’s true

Species counts miss genetic and ecosystem variety, and appearance alone cannot establish genetic differences.

If your child says… “A bigger area means fewer species.”

Ask together

Which direction does the species–area curve go as area increases?

What’s true

The species–area model describes a broad trend, not a guarantee for every comparison between sites.

If your child says… “Every species does the same job.”

Ask together

Could any other species automatically replace a lost pollinator?

What’s true

Species have different roles, although some can partly compensate for others.

If your child says… “The recorded list includes every extinction.”

Ask together

How would a list include a species nobody had discovered?

What’s true

Species can disappear before discovery or without anyone recording their loss.

If your child says… “Species can suffer coextinction without depending on each other.”

Ask together

What could the parasite survive on after its only host species vanished?

What’s true

Coextinction involves dependence on a species that disappears.

If your child says… “Every species-rich forest is a hotspot.”

Ask together

What must we also know about unique species and habitat loss?

What’s true

Many species alone do not establish hotspot status.

If your child says… “Seed banks can save every species.”

Ask together

What if a plant's seeds cannot survive drying and cold storage?

What’s true

Other species need living collections, frozen reproductive material or managed breeding.

If your child says… “A Red List category saves the species.”

Ask together

What changes in a forest just because its threatened species receives a category?

What’s true

A risk category alone cannot protect habitats or rebuild populations.
