This memoir describes how I, a young scientist who believed that

“applied science" was second-rate science, found myself -- by chance

and serendipity -- studying the ecological consequences of acid rain

and radioactive fallout, purely as fascinating phenomena and without

thought of mitigation. As I continued with their study and taught

students about them, I became more and more aware of their significance

for society, so that after twenty years -- and again by chance and

serendipity – I became an environmental activist. Since then I have

testified about environmental deterioration, attended scientific

committees and workshops, and advocated for pollution control in both

academic and societal settings.
