The world has a big problem. The water in our oceans is very hot now. Scientists look at the water every day. They say the temperature is higher than before. This is not good for the Earth or the animals in the sea.
Why is the water so hot? There are two main reasons. First, the air is getting warmer because of people. We use cars and factories. These things make the air hot. The oceans take this heat from the air. Second, there is a natural event called El Nino. El Nino happens every few years. It makes the water in the Pacific Ocean very warm. When this happens, the whole world feels the heat.
Hot water is bad for fish and plants. Many small fish cannot live in very warm water. When small fish die, big fish do not have food. Also, coral reefs are in danger. Coral reefs are beautiful homes for sea animals. When the water stays hot, the coral turns white and dies. This is a sad thing for the ocean.
Warm oceans also change the weather. They can make big storms and a lot of rain. Some places have too much water, and other places are very dry. This makes it hard for farmers to grow food for us to eat.
We need to help the oceans. We can walk more and drive cars less. We can use less energy at home. If we take care of the air, we take care of the water too. Scientists say we must act now. The oceans are very important for our life. We want the fish and the sea to be healthy for a long time. We must learn about the earth and help our blue planet. Learning about the environment is a good way to start. It is important to help the world today.
