Progress in eradicating polio

The World Health Organization (WHO) began the Global Polio Eradication Initiative (GPEI) in 1988 with the goal of eradicating polio. The main tool used to eliminate polio was the oral polio vaccine. Use this dataset to explore what has happened in different locations around the world since the GPEI efforts began.

Green plants use light energy to produce their own food with photosynthesis You may have already learned that plants require water and carbon dioxide and light for photosynthesis and produce oxygen and glucose sugar in the process. If one of those three inputs (water, carbon dioxide, or light) is in short supply, then photosynthesis will slow down or even stop. How does light intensity affect the rate of photosynthesis?

What is the relationship between temperature change and mass extinction?

Climate change affects all life on earth. Predicting how a warming climate will affect species on earth is one of the biggest goals for climate researchers today. Despite the importance of this goal, a precise answer to the question of how climate change will affect species in the future is still being sought. One of the key places that scientists look for answers is in the past. Specifically they look to geologic data to provide insight into how past temperature changes and extinction rates have been correlated so that we can make predictions about the effect that our now warming climate may have on species currently living on our planet.
