The passage discusses the vast and diverse marine ecosystem, highlighting its complexity and the challenges in studying it. It mentions the diverse biodiversity in the sea, with many species still unknown. The passage points out that while we've explored much of the Earth's surface, the depths of the ocean remain largely uncharted. It also mentions the problem of overfishing and other human impacts on the marine environment. The passage concludes by emphasizing the importance of environmental conservation and the role of the younger generation in addressing these issues.
1. The sea is more diverse and abundant than what we see on land. The marine geography, mountains, and sea depths are bigger and deeper than anything we find on land.
2. Biodiversity in the sea is much more diverse and abundant than what we see on land. There are many more species in the ocean than on land, with many still undiscovered.
3. The Earth's surface has been completely explored, probably for most land areas. However, the bottom of the sea remains largely unknown.
4. The ocean floor needs to be scanned to figure out what happened in incidents like the disappearance of Malaysia Airlines Flight 370.
5. Many parts of the ocean are very deep, making it expensive and challenging to study.
6. The oceans cover 70% of the globe or more.
7. The oceans have very interesting and diverse parts that are difficult to access, such as Antarctica.
8. The ocean has a wide variety of organisms, including animals that look like plants and worms that look like flowers.
9. All the biodiversity in the oceans is concentrated in specific places, such as coral reefs and mangroves.
10. There are some marine ecosystems that do not depend on sunlight, such as fumaroles, which are places where magma coincides with the sea floor.
11. The oceans have many different environments, ranging from shallow seas of warm water to deep seas of cold water.
12. The oceans are under a lot of stress from pollution and global fishing.
13. The impact of humans is much greater in shallow waters, causing stress to the environment.
14. Global fishing has been a major problem for several years, leading to concerns about how long the ocean can support current activities.
15. The modern generation is more environmentally conscious than previous generations, leading to increased awareness of the needs of the ocean.
