Hi Dasha,

That's an interesting question. The first person to discover food would have been the first person on Earth - because they needed to eat. The first people probably ate what they found - like fruits, berries, bird eggs and things they could catch like fish. No one knows who that was. A grain like wheat called Emmer was probably the first food humans grew - about 19,000 years ago. We don't know the exact person who discovered how to grow Emmer.

Why do hurricanes only come to the coast and not in the middle of the U.S.?

Hi Hope,

That's a good question. Hurricanes need warm water for energy to keep spinning. They can only be create and survive when over the water. When a hurricane hits land it starts to lose speed and slows down until it is just strong wind and rain. If winds do spin fast over the land they create a different shape and usually don't have lots of rain - we call that a Tornado.

What are the oldest living things (that are still alive today) in the world?

Hi Shaskia John,

The oldest living things still alive today are called Stromatolites (pronounced - stroh-MAT-toh-LITES). These are blue-green algae, little one-celled creatures, that live in the warm shallow ocean water along the west coast of Australia. They grow very slowly. The small mounds they for look a little like coral. Stromatolites are the most common thing scientists find amongst the Earth's oldest fossils from 3.5 million years ago.

What is Global Warming?

What is global warming?

GLOBIO Traveling Teacher says:

Hi Karan,

That's a very important question. Global warming means: an increase in the average temperature near the Earth's surface (ocean and land). Some of things that may make the temperature rise are caused by natural events like gases from volcanoes and other events are caused by humans, such as exhaust from vehicles and cutting of large areas of forest. If this warming continues every year then it creates Climate Change. Many people use the term Global Warming and Climate Change to mean the same thing - but they are not exactly the same. Climate Change means any changes in the climate - not always warmer, it could be colder, and it could mean more rain or storms like typhoons. Climate change has been going on since the beginning of the Earth

What Kind of Animals Live In Temperate Forests?

Perla from Puerto Rico wrote:
what are the kind of animal that live in the temperate forest because my class is doing a project with it can you please help me?

GLOBIO Traveling Teacher says:

Hi Perla,

That's a good question, but it has many answers. The answer depends on which temperate forest you want to know about - there are temperate forests on every continent. In North America you might find black bears, deer, squirrels and cougars, but if you travel to China you find giant pandas, red pandas, Asiatic black bears, and golden monkeys. So it really depends on which temperate forest you are curious about. Write us back and maybe we can help more.

GLOBIO Traveling Teacher says:

Hi Anaga,

Oranges grow in most tropical and sub-tropical countries where the days are hot and the night do not freeze - places like Brazil, Central America, Mexico, Italy, Morocco, Israel, Australia, Kenya, USA (Florida and
California) and south China. The orange fruit originally came from Southeast Asia.

How Old Is the Earth?

Ariana P. from the United States wrote:

when was earth born

GLOBIO Traveling Teacher says:

Hi Ariana,

Scientists testing rocks believe that Earth, and the rest of the solar system, began to form about 4.5 billion years ago in a giant cloud of dust and gas. Over time, dust particles began to clump together. It probably took the clump that became Earth tens of millions of years to reach its current size. The young Earth had no water, no atmosphere, and no life-forms.

A little over 3.5 million years ago life started to appear on the new Earth.
