How humans impact on Earth?

The main purpose of video is showing species of organisms on Earth and how our specie influence environment. In spite of the fact that humans are only 0,01% of all life on Earth, we have major impact on our planet. For example, we alter landscapes and literally move mountains. However, terrifying is fact that we are responsible for trampled out 84% of animals and more than 50% of plants. Other point of video is explanation of term "biomas". It's the mass of living biological organisms.


Literally - In this film, main character literally goes back in time.

Impact- Social media have bad impact on teenagers.

trample - Someone trampled my roses!

Wonderfull and Deadly Glowing Sand

Obraz
Will Ho, a marrine biology photographer from Taiwan, captured amazing images of glowing blue sand, on the beach in the Maledives. As a matter of fact, this glow was caused by living creatures, which are actually a type of bioluminescent plankton called Lingulodinium polyedrum. Typically, these creatures float around the ocean undetected. They don't glow all of the time. It takes energy to make the chemicals that allow them to glow. However, when they are under stress, whether from strong current or crashing wave, they emit beautiful light. This marvelous phenomenon was used by director Ang Lee in the film  "Life of Pi". Nevertheless, this phenomenom is not a good think. It's also know as a "red tide", what is common term used for harmful algal bloom. Some of these tiny organisms produce toxins that kill marine animals, make shellfish dangerous to eat and have harmful effects for human. National Ocean Service have been monitoring and studying this phenome

Christmas Island Red Crab Migration

Obraz
Adult red crabs begin their breeding migration to the sea as soon as the wet season starts and can last up to 18 days. This proces is fixed around the phases of the moon. If there isn't enough time for individual parts  of their migration, they will delay the start. Female Red Crabs release eggs into the sea precisely at the turn of the high tide during the last quarter of the moon. The eggs hatch immediately on contact with the sea water. After about a month in the ocean, "Crab babies" gather  and leave the water. Numerous humans activities contribute to increased mortality among Red Crabs. The most common cause is crushing by vehicles .  For these reasons, "crab crossing" are being constructed on roads which cross main crab migrations. Chief Ranger Muller and his team are currently helping 50 million crabs on their annual migration. They have spent months for preparing more than 20 kilometres of plastic barriers, 31 crab underpasses and five metre-h

Peacock and computer screen

The main topics in this podcast are peacocks and colors. Lector tells some basic information about peacocks and their behavior, how work human receptors and what is the difference between normal color and color on peacock's tail named structural color. And how people could use structural color in technology.  I think that it's great idea to save energy. If we could make colors through complex structures instead of normal screens, we would in some way relieve to our planet. Nowadays, people use a lot of electronic devices. Everybody need some of them to life in our society. New screen with structural colors could be a really valuable invention. https://www.bbc.co.uk/sounds/play/p07phxzq
