The Sun's warmth reaches it just two minutes before it touches us. In size and composition, Venus is very like Earth, but the small difference in orbital distance made all the difference to (3)how it turned out. It appears that during the early years of the solar system Venus was only slightly warmer than Earth and probably had oceans. But those few degrees of extra 20 warmth meant that Venus could not hold on to its surface water, with disastrous consequences for its climate. As its water evaporated, the hydrogen atoms escaped into space, and the oxygen atoms combined with carbon to form a dense atmosphere of the greenhouse gas CO2. Venus became stifling. Although people of my age will recall a time when astrononmers hoped that Venus might harbor life beneath its padded 25 clouds, possibly even a kind of tropical vegetation, we now know that it is much too fierce an environment for any kind of life that we can reasonably conceive of. Its surface temperature is a roasting 470 degrees centigrade (roughly 900 degrees Fahrenheit), which is hot enough to melt lead, and the atmospheric pressure at the surface is ninety times that of Earth, or more than any human body could withstand We lack the technology to make suits or even spaceships that would allow us to visit Our knowledge of Venus's surface is based on distant radar imagery and som。 disturbing noise from an unmanned Soviet probe that was dropped hopefully into the

On July, a Japanese friend named Toshi and I decided to climb Kitadake, who is Japan's second highest mountain. Knowing this wouldn't be easy 1I started training. I went jogging and swimming regularly to trying and prepare and was feeling fit and ready at the end of July. At the beginning of August, the number of Corona cases was increasing so unfortunately we had to change our plans. Toshi doesn't want to catch the bus from Kofu to the Suothern Alps because of the risk of Corona infection, so we stayed in Shizuoka prefecture. Yanbushi was a mountain, 2014 meters high. It is not far from Umegashima, which is famous for it's hot springs. Instead of Kitadake, we climbed Yanbushi. In August 10, we woke up early and drove to the starting point. It was the day after a typhoon had passed and a beautifull, clear morning in Shizuoka city. However when we arrived, it was very cloudy and it was raining lightly. After a three and a half hour climb we arrived at the summit. It rained most of the way but it wasn't so bad under the trees and actually kept us cool. It was a challenging and rewarding experience. Ithink exploring nature is a fun, healthy and interesting way to spent your free time. T have included a photo of my climb.

When Ogasawara people go to Tbkyo, they have to take a ferryboat for 24 hours because there is no airport. Ogasawara Islands are far from the main islands, so there are many kinds of *unique plants and animals.They are called *endemic species. Thirty - six percent of the plants on the islands'are endemic species. We can see those plants only in Ogasawara Islands. Because only plants and animals that have *adapted to Ogasawara *environment could *survive, unique *ecosystems were developed.

Animal doctors and volunteers took care of them and looked for their new fanmilies. From 2008 to 2018, about 800 stray cats were sent to Tokyo to start their new ife.
