<br/><br/> Many ecosystems are in danger. When animals start dying in a certain ecosystem, the food chain is altered and more animals die. Things like pollution can also cause problems. To understand why a certain part of an ecosystem's population is dying, you have to collect data. When you collect data, you can make predictions and turn your predictions into solutions.
