Asteroids are large space objects made of rock and ice. There are hundreds of thousands of asteroids in our solar system. Though we often hear ideas about establishing colonies of humans to live and work on our Moon or our neighboring planet, Mars, some think that sending people to an asteroid would actually be the best colonization option for a number of reasons.
Low Gravity
To begin with, asteroids are often much smaller than planets, so they have lower gravity. When landing a spaceship, the craft would not be pulled as strongly or as forcefully toward the asteroid's surface, making the landing safer than landing on the Moon or Mars; it would also allow a spacecraft to carry much more equipment needed to set up the colony. It would also be easier for the spacecraft to take off again, so the spaceship would need to carry considerably less fuel for the trip back to Earth.
Mining Valuable Metals
Next, some asteroids are rich in valuable elements and precious metals that are relatively rare on Earth, such as gold and platinum. An asteroid colony would be extremely profitable and a good source of these raw materials. The colonists or businesses sponsoring them could more than pay for the cost of their support by mining minerals and sending them back to Earth.
Easy to Reach
Humans have long been fascinated by elephants, the largest land animal in the modern world. Social animals that live in herds, elephants are native to both Africa and Asia. Their large ears, long trunk, and long life span have made elephants one of the most captivating creatures on Earth. Our long-standing interest in elephants has led to several beliefs about surprising elephant behaviors.
Elephants Are Aware of Approaching Death
One of the popular beliefs is that when elephants become old and weak, they know that they are nearing the end of their lives. They demonstrate this by breaking away from their herds and going off alone to certain locations often found near bodies of water - so-called "elephant graveyards" - to die alone. The idea that old elephants seem aware that they will die soon is supported by the discovery of many sites containing bones exclusively of elderly elephants.
Representing Objects through Art
Additionally, elephants seem to have artistic ability. Elephants can be taught to hold a paintbrush in their trunk and use it to paint on a canvas. Some elephants have been known to paint drawings that represent recognizable things: flowers, other elephants, even themselves. This talent makes elephants the only animal other than humans to produce art representing the world around them.
Fear of Mice
Finally, it has long been believed that elephants have a fear of mice. In 77 C.E., the Roman philosopher and scientist Pliny the Elder wrote that elephants are more afraid of mice, small mammals that can do elephants no harm, than of the much more dangerous animals with which elephants normally share an environment, such as lions or tigers. In a recent scientific experiment in which a herd of elephants was confronted with several mice, the elephants backed away from the mice and left the area to avoid them.
The lecture and the article are both about the features in the elephants that seperate them as a intelligent and fascinating animals. The author mentions three features of elephants that are unique. On the other hand, the lecturer disagrees with the reading by refuting the existense of these features in them.
First, the reading states that elephants are extraordinarily aware of the end of their lifes. They will go somewhere near the rivers and isolate themselves to prepare for dying. The lecturer denies this behavior in the elephants. He mentions that when the elephants become older their teeth lose their intial abillity to grinde rough vegetables, as a result, they leave the herd and look for the area that soft plants grow which almost in the vicinity of the rivers.
Second, the author mentions that the elephants have some amazing abillity to paint unlike the other mammals. He states that they are able to hold the paintbrush by their trunks and paint some recognizable and real things. The lecturer opposes this assertion too. He says that they don't consciously and solely draw the paintings, but they forced by the humans to draw the lines and the shapes in order to create a picture of the real things. The author adds that the ears of them are very sensitive and trainers use its ears in order to force them to paint a particular paintings.
Finally, the reading states that elephants are frightening from the mice. He points out that they have fear to face the mice more than dangerous animals that able to hurt them. The lecturer refutes this behavior too. He mentions that some elephants which are kept in the zoo don't show this behavior because they are familiar with mice, so he believes that the reason of this fear is that the elephants are unfamiliar with the mice in their habitats.
