The Wonders of the Ocean
The ocean is one of the most wonderful ecosystems on earth. It covers around 71% of the earth's surface and is home to millions of species. From tiny fish to huge whales, the ocean is full of life.
The ocean produces about 70% of the earth's oxygen. Plants in the ocean, like algae, take in carbon dioxide and give out oxygen. This is very important for all living things on earth.
The ocean also helps control the earth's climate. It stores heat from the sun and moves it around the world. This helps keep the climate balanced.
But the ocean is in danger. Pollution, such as plastic waste and wastewater, is harming sea life. Overfishing is also a problem, as it reduces the number of fish in the ocean. We need to take action to protect the ocean, such as cleaning up beaches and using less plastic.

The Importance of Wetlands
Wetlands are important ecosystems on earth. They cover about 6% of the earth's land area, but they are home to about 40% of the world's plants and animals. Wetlands can be found in many places, from small ponds to large areas near rivers and lakes.
One of the most important jobs of wetlands is to clean water. Plants in wetlands help get rid of pollution and make the water clean. Wetlands can also help prevent floods. During heavy rains, wetlands store water like giant sponges. This helps reduce the risk of floods in nearby areas.
Wetlands are also home to many rare and endangered species. For example, the red-crowned crane lives in wetlands. Without wetlands, these animals would have no place to live and could die out.
However, wetlands are facing many problems. People are using wetland land for farms and buildings, which reduces the size of wetlands. Pollution from factories and homes also harms wetlands. We need to protect wetlands to keep our environment healthy.
(1)、What percent of the earth's land area do wetlands cover?A、About 6%. B、About 40%. C、About 71%. D、About 70%.(2)、What can wetlands do to help during heavy rains?A、Cause floods. B、Store water.
