A river is very strong. It takes water from the mountains to the ocean, and it's always pushing forward. A river is full of power!
河流的力量很強，可以把水從山上一路帶到海裡。
How can people use that power? On many rivers, people build a dam. A dam is a wall across the river. The dam can hold back the water, and use the river's power to make electricity for people.
人們會在河川上蓋水壩，把水攔住，用河流的力量發電。
More dams make more power, and more electricity for us to use. That sounds good… but actually, people have decided to remove the dams from a river in California.
越多水壩，就有越多電，聽起來不錯吧？但最近，加州的人決定把他們一條河上的水壩都拆掉。
That's because people are not the only ones who use the river. Fish also need to live there.
因為不只是人類需要河流，魚類也需要生活空間。
For the salmon, the river is like a road. Every year, the salmon swim up the river to lay their eggs.
對鮭魚來說，河流就像一條路。鮭魚每一年都會逆流而上去產卵。
When the eggs hatch, the baby salmon swim back down the river to reach the ocean. It's the circle of life.
卵孵化之後，鮭魚寶寶會順流而下游回大海。
But those fish can't swim up and down the river if there is a dam! To help the salmon live, people in California will take the dams away.
但如果有水壩擋路，那些魚就不能在河裡游上游下，所以人們決定把水壩拆掉。
Even though dams are useful, they also harm the environment. Let's respect the fish and take those dams down!
