All of that happen because of the Ozone layer is getting thin and has hole. Which make the sunlight go directly to the earth. The ice in North Pole and South Pole is melted and become water. That makes the sea level up and many islands are under the water. If that continue happening, can you imagine, where we going to live?
Ozone layer is protecting us from the danger of sunlight. Sunlight is very important to support our life. Without it, there is no plant, no animal and no life. We need sunlight to grow our plant and animal. Plant and animal are our food sources. We need water too. Without evaporation of river and sea water, there is no rain. And sunlight plays important role. But if we get sunlight directly, we will get burn, the ice melted and the plant dry. The dry plant can create fire in the jungle. And burn everything.
For human being, sunlight is good for our body to feel better and healthy. Sunlight helps bone growth. But too much of sunlight, we can get skin cancer. It can damage the skin. So Ozone layer is important layer in the sky to protect us from direct sunlight.
