Seven record-breaking farming records to inspire you to change the world

12 April 2019

       This month, Guinness World Records has partnered with US-based youth organization 4-H to celebrate “farmfluencers" who are changing the future of agriculture.

       The farming industry has been around for 10,000 years, but every day bright young minds are finding new opportunities to innovate and change the face of agriculture around the world. 4-H is hosting a global video competition that invites and empowers young people to become more connected with farming.                                                          To join in the spirit, we’ve corralled together a list of seven record-breakers who can inspire you to learn more about farming.

Tallest living horse

       The tallest living horse is Big Jake, an 18-year-old Belgian Gelding horse, who measures 20 hands, 2.75 in (210.19 cm, 82.75 in), without shoes. The average height of a Belgian horse is usually between 16 and 17 hands. 

       Big Jake was first measured on January, 19 2010 at his home - Smokey Hollow Farms in Poynette, Wisconsin, US. He has since become quite the celebrity. Jerry Gilbert, his loving owner and farm manager, says that the mighty animal loves being the center of attention – and that getting belly rubs and his neck scratched are his favorite things.

III. Further reading

  Oceans cover 70 percent of the Earth's surface, yet even today, their depths remain largely unexplored. Scientists estimate that  90 to 95 percent of the deep sea remains a mystery. The deep sea is truly the planet's final frontier.

 

What is deep sea exploration

       The term "deep sea" doesn't have the same meaning to everyone. To fishermen, the deep sea is any part of the ocean beyond the relatively shallow continental shelf. To scientists, the deep sea is the lowest part of the ocean, below the thermocline (the layer where heating and cooling from sunlight ceases to have an effect) and above the sea floor. This is the part of the ocean that is deeper than 1,000 fathoms, or 1,800 meters.

                                                                           

       It's difficult to explore these depths because they are eternally dark, extremely cold (between 0 degrees C and 3 degrees C below 3,000 meters), and under high pressure (15,750 psi or over 1,000 times higher than standard atmospheric pressure at sea level). From the time of Pliny until the end of the 19th century, people believed the deep sea was a lifeless wasteland. Modern scientists recognize the deep sea as the largest habitat on the planet. Special tools have been developed to explore this cold, dark, pressurized environment.

  Deep sea exploration is a multi-disciplinary endeavor that includes oceanography, biology, geography, archaeology, and engineering.

  Like space exploration, deep sea exploration requires new instruments and technology. While space is a cold vacuum, the ocean depths are cold, but highly pressurized. The saltwater is corrosive and conductive. It's very dark.

 

1. Why is it difficult to explore the depths of the ocean?      

  Because the deep sea is eternally dark and under high pressure.

 

2. Is the deep sea a lifeless wasteland?

  No.

3. Compared to outer space, what kinds of conditions does the deep sea have?

  While space is a cold vacuum, the ocean depths are cold and highly pressurized. The saltwater is corrosive and conductive. It's very dark.

 

 

IV. Post reading

·Do some research on what life is like in the deep sea.

·Group activity - Design a poster to help people learn more about our oceans and raise awareness of the importance of protecting them.
