The Magnetic Wand That Cleans Oil Spills: Upgrade. CORAL REEFS - POLYPS IN PERIL. Overfishing Intro - Revolution. Discover the threats, causes and impacts, and how you can help. Fishing for Answers Inspired from the movie Revolution and narrated by Rob Stewart, our Educational Video gives you more content on Overfishing. Fish are the first vertebrates on Earth and evolved into the diverse array of vertebrates you see today. Look back in your family tree, about 530 billion years ago, and there will be a prehistoric fish.[1. About.com fish Evolution.] Jawless fishes filled oceans, lakes and waterways 490 million years ago kickstarting vertebrate evolution.
Prehistoric sharks appeared 400 million years ago – followed shortly thereafter by the ray-finned fishes that evolved into 96 percent of all freshwater and marine fish species[2. Sharks are overfished for their fins Just recently census scientists increased the number of known marine species to about 250,000. From larval forms of fish, or zooplankton, right on up to the apex predators like tuna and sharks, it’s eat or be eaten in the world of fish.
Coral Reefs - Infographic animation. Ocean Acidification Intro - Revolution. Discover the threats, causes and impacts, and how you can help. The New Threat to Our Oceans The ocean is the most important part of humanity’s life support system. Oceans regulate climate, atmospheric and ocean chemistry, carbon, food supply and oxygen. Without the ocean, the evolution of life on Earth would not have begun 3.5 billion years ago. Inspired from the movie Revolution and narrated by Rob Stewart, our Educational Video gives you more content on Ocean Acidification. Ocean Acidification has emerged to become one of the biggest threats to our oceans, and now our life support system is in jeopardy. Carbon emissions that are released into our atmosphere from transportation, factories, and from heating and cooling are being absorbed by the ocean. As the chemistry of our oceans changes faster than animals can evolve to adapt, we could lose entire species and ecosystems, (including plankton).
Phytoplankton have declined approximately 40 percent since 1950. Phytoplankton ? Why are coral reefs so important? | Natural History Museum. Coral Reefs: Unraveling the Web. Conserving our spectacular, vulnerable coral reefs - Joshua Drew. Coral reefs prepare for warmer waters. The Persian Gulf's coral reefs are not the biggest. They are not the prettiest, either. They do not even have as many plants and animals as some other reefs. But they have become a favorite spot for scientists to study. The water in this area is very warm. Persian Gulf corals can handle water that is up to 36 degrees Celsius (97 degrees Fahrenheit). Other coral reefs can only handle water as warm as 29 degrees C (84 degrees F). It might only sound like a few degrees difference, but it's a big deal for the corals. Coral And Algae Work Together Corals live together with the algae.
John Burt is a marine biologist. Burt has been studying the Persian Gulf corals for the last three years. Burt did not work alone in the Persian Gulf. Burt and his team believe the new algae is what makes the Persian Gulf corals so much better at living in warm water. Many Things Have Hurt Reefs Coral reefs have been in danger for many years. The scientists want to move some algae to other reefs to protect them. Ways to Help Coral Reefs. 10 Easy Steps to Help Protect Coral Reefs Do you want to make a difference every day? Want to learn about simple, effective actions you can take to help save coral reefs and the fish, animals, and plants that depend on them? You've come to the right place!
