Bilal Haq was born in the foothills of Himalayas (Gorakhpur) where his father Mohammad Fazl-i-Haq was a senior ICS officer in the British Indian government.

[10] He was seconded to the World Bank in Washington, DC in their Environment Department, where already in 1994 he produced a special report on the effects of climate change and sea-level rise on the economies of developing maritime nations.

Among Bilal's many services to the scientific community was his rescue of a prolific fossil site in the Shandong province of China (Confucius' birthplace) through an international appeal,[15] (now a National Geopark).

He also conceived and helped create a paleontological Geopark (together with the Chinese biologist and academician, Zheng Shouyi) consisting of giant sculptures based on fossil micro-organisms (Foraminifera) in Zhongshan City in Guangdong Province.

In the past his focus was on documenting sea-level changes along the world's continental margins and interior basins for the last 550 million years of Earth history (the complete Phanerozoic Eon).

His international appeal saved a prolific fossil site from destruction (that was later declared a National Geopark) in Shandong Province in China and he helped create two Foraminiferal sculpture parks in Guangzhou and Qingdao.
