***********************************
Kanji Nishi used to catch many big bluefin tuna near Iki Island. But now, there are almost none left. In 2005, fishermen there caught 358 tons of tuna. In 2014, they only caught 23 tons. Many young fishermen have quit. Experts say overfishing is the main reason. Most tuna are caught before they can grow up and have babies. This is hurting the population.

Japan made some fishing rules, but experts say they are not strong enough. The rules are based on old data, and many fish are still being caught in spawning areas. Some people and companies want to fish more sustainably, but the government has close ties with big fishing businesses. This makes it hard to change.

Some local fishermen started a self-ban in summer to protect the fish. But real change needs stronger government action. If nothing is done, future generations may never see bluefin tuna in the sea.

******************************
In the vast Ténéré Desert of Niger, an African country, there once stood a tree like no other. It was the only tree for 400 kilometers in every direction—completely alone in the barren landscape.

Why was this tree so isolated? Long ago, it was part of a forest, but as the land became dry, all the other trees perished. This lone tree survived by drawing water from deep underground.

The Tuareg people revered the tree, considering it a symbol of hope. Even European maps from the 1930s marked it as a landmark for travelers.

However, in 1973, tragedy struck. A drunk driver crashed into the tree, toppling it. People around the world were shocked by its loss.

Today, the tree’s remains are preserved in the Niger National Museum, and a metal sculpture now stands in its place.
