There are growing fears that within 100 years, pollution will destroy the world's biggest collection of rock art.
Scientists around Australia believe the findings of a new report claiming industrial pollution has no effect on ancient rock art, are patently wrong and could have disastrous ramifications.
Rock conservationists Ian MacLeod and Warren Fish recently published a paper which suggests there is no adverse impact on the engraved rock art of Murujuga from industrial pollution.
Murujuga contains the highest concentration of ancient rock engravings in the world and captures more than 50,000 years of Indigenous knowledge and spiritual beliefs.
