Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
Why is it important to protect marine ecosystems?
Marine protected areas help protect important habitats and representative samples of marine life and can assist in restoring the productivity of the oceans and avoid further degradation. They are also sites for scientific study and can generate income through tourism and sustainable fishing.
What is the most important marine ecosystem?
The most important marine ecosystems for marine life are estuaries and coral reefs. These two marine ecosystems are important because the estuaries are breeding territories for many marine animals, because it is easy for young-lings to survive there, since there are no known predators that live in that region.
What does the marine ecosystem provide?
The ocean supports economic activity, including jobs, fisheries, food, marine transportation, trade, fuel, and energy. The ocean supports nutrient cycling and primary production. species that can be supported indefinitely in a defined habitat without permanently impairing the productivity of that habitat.
Are oceans important to us?
The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
Why are marine mammals important?
Marine mammals play important ecological roles as both predator (many hunt for fish) and as prey, both for sharks and other, larger marine mammals. Humans have also long hunted marine mammals for food and fur.
Why are freshwater and marine ecosystems important?
The ecosystems in rivers and streams, for example, bring salts and nutrients from the mountains to lakes, ponds, and wetlands at lower elevations, and eventually they bring those nutrients to the ocean.
Why species diversity is important for the health of marine ecosystem?
A high biodiversity, including species richness, may enhance ecosystem processes and promote long-term stability by buffering, or insuring, against environmental fluctuations (Yachi and Loreau, 1999; Loreau, 2000).
Why is it so important to explore the ocean?
Exploration is key to increasing our understanding of the ocean, so we can more effectively manage, conserve, regulate, and use ocean resources that are vital to our economy and to all of our lives. … Ocean exploration is about making discoveries, searching for things that are unusual and unexpected.
How important is the ocean to our economy?
In addition to its crucial role for regulating the climate and weather, the ocean is vital to the world’s economy, with more than 90% of trade using sea routes and as a source of jobs for millions of people.
Why is the ocean important essay?
More than 90 percent of the trade between countries is carried by ships. Fish supplies from the sea and oceans are the world’s greatest protein supply to the humans. Around more than 3.5 billion depends on oceans for their primary food. 70% of the oxygen that humans breathe are produced by oceans.
