As much as these resources are renewable, it may take tens to hundreds of years to replace them. The renewable raw materials that come from living things namely animals and trees are termed as organic renewable resources while those that come from non-living things such as sun, water and win...
Terms like "reef-safe" or "reef-friendly" are typically used to identify sunscreens that do not contain oxybenzone and octinoxate, two common UV-blocking chemicals, that studies have shown can cause coral bleaching. When coral bleaches (turns white), it's still alive, but it's under severe...
We can see bright areas, which look a little bit like under water islands. These areas are coral reefs. Why are these features able to be imaged by satellites? It's difficult for satellites to see through water, but because there is so much coral close to the surface of the water we ...
