The Amazon River

The Amazon River, which flows through Brazil, is the largest liver in the world by the quantity of water, and its drainage basin is almost as large as Australia. Although some people think the river is the longest in the world, the Nail River is the longest river, so the Amazon is the second longest river.
Above all, the Amazon is famous for many kinds of life that range there. For example, piranhas, pythons and sharks that live in fresh water. Because the river was formed about 5 hundred million years ago, there are fishes that have been changeless since then, and they are sometimes called living fossil. In addition, there are rare plants and birds there, such as carnivorous and birds that prey on monkeys. However, it is said that many kinds of life are not found yet, and many explorers look hard for them.
I want to visit there and see them someday.

The Sahara

The Sahara, which covers most of Northern Africa, is the largest desert in the world, and accordingly it is one of the most famous deserts. However, few plants or animals thrive in the desert, so it is hard for people to live there. In addition, there are many sand dunes, and sandstorm rises frequently.
Five hundred thousand years ago, it was a damp climate there, and people who live there prospered in trade, yet the pace of desertification there is the most rapid in the world now. Regardless of the surroundings, they still have original culture and they are managing well, and furthermore, marathon races and rallies take place there. Then, many people visit there, and it is said that they are all surprised at the vast reach of desert.
Therefore I want to visit there in order to know the present condition.
