Baikonur Cosmodrome [SEP] Environmental impact
Russian scientist Afanasiy Ilich Tobonov researched mass animal deaths in the 1990s and concluded that the mass deaths of birds and wildlife in the Sakha Republic were noted only along the flight paths of space rockets launched from the Baikonur cosmodrome. Dead wildlife and livestock were usually incinerated, and the participants in these incinerations, including Tobonov himself, his brothers and inhabitants of his native village of Eliptyan, commonly died from stroke or cancer. In 1997, the Ministry of Defense of the Russian Federation changed the flight path and removed the ejected rocket stages near Nyurbinsky District, Russia. Scientific literature collected data that indicated adverse effects of rockets on the environment and the health of the population.
