Using the Asteroid Zoo web site, you can contribute to the hunt for asteroids by simply applying your Mark II Eyeball and its Wetware computing processing which evolved over millions of years to spot patterns such as the visual differences caused by things that move. It was refined to help us spot things trying to eat us, things falling on us, and things we could eat, but it also makes us the optimal processing instrument for spotting planets, comets, meteors, and asteroids from sky survey photographic sequences. What makes spotting such objects useful and worth your time? The answer depends on whether you are an optimist or a pessimist. The pessimist will be looking for things trying to fall on us, alerting NASA, the ESA, and others so we can destroy or deflect them before they can impact and damage our world. The optimist will be looking for low flying rocks that we can capture and mine for resources such as metals and volatiles (fuel and food). Whatever your reason, it contributes to humanities knowledge and the protection of the world, so it is a good thing. Thanks to the folks at Planetary Resources for making it possible, and thank you if you contributed to the programs Kickstarter funding.
