Like many other marine animals, sea turtles mistake plastic waste for a viable food source, sometimes causing blockages in their digestive system. Though the declining sea turtle populations in the oceans are due to a variety of factors (most all of which involve human exploitation), plastic pollution plays a significant role.

Robotic systems perform many functions such as repetitive tasks performed in research. These range from the multiple repetitive tasks made by gene samplers and sequencers, to systems which can almost replace the scientist in designing and running experiments, analysing data and even forming hypotheses. The ADAM at the University of Aberystwyth in Wales can “[make] logical assumptions based on information programmed into it about yeast metabolism and the way proteins and genes work in other species. It then set about proving that its predictions were correct.”
Autonomous scientific robots perform tasks which humans would find difficult or impossible, from the deep sea to outer space. The Woods Hole Sentry can descend to 4,500 metres and allows a higher payload as it does not need a support ship or the oxygen and other facilities demanded by human piloted vessels. Robots in space include the Mars rovers which could carry out sampling and photography in the harsh environment of the atmosphere on Mars
