What are three ways in which projected climate change could threaten aquatic biodiversity?

How does climate change threaten aquatic biodiversity quizlet?

How does climate change threaten aquatic biodiversity? Partly by causing sea levels to rise. Such a rise in sea level would destroy more coral reefs, swamp some low-lying island, drown many highly productive coastal wetlands, and put many coastal areas such as a large part of the U.S. Gulf Coast, under water.

What are the 3 general patterns for marine biodiversity?

Three patterns of marine biodiversity are: 1. The greatest marine biodiversity occurs in coral reefs, estuaries, and on the deep-sea ocean floor. 2. Biodiversity is higher near the coasts because of great variety of producers, habitats, and nursery areas.

What are the top three argued threats to marine systems?

Multiple causes of the oceans’ critical state. Be it overfishing, marine pollution, ocean warming or acidification – today the oceans and the ecosystem services they provide are under more serious threat than ever before.

What are two harmful effects on aquatic systems resulting from the increase in the human population in coastal areas?

What are two harmful effects on aquatic systems resulting from the increase in the human population in coastal areas? Oceans are becoming more crowded and noisier. Give two examples of how pollution is affecting aquatic systems. Chemicals such as DDT, PCBs, and mercury are polluting their habitat.

What are major threats to aquatic biodiversity?

Six threats affect aquatic biodiversity; climate change, overexploitation, water pollution, habitat degradation, flow modification and exotic species invasion. Biodiversity maintenance is considered one of the leading keys to ecosystem services retention.

What do you think are the three greatest threats to aquatic biodiversity and aquatic ecosystem services?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

How are coral reefs threatened?

The top threats to coral reefs — global climate change, unsustainable fishing and land-based pollution — are all due to human activities. These threats, combined with others such as tropical storms, disease outbreaks, vessel damage, marine debris and invasive species, exacerbate each other.

How can we help sustain aquatic biodiversity?

Sustaining the world’s aquatic biodiversity requires mapping it, protecting aquatic hotspots, creating large, fully protected marine reserves, protecting freshwater ecosystems, and carrying out ecological restoration of degraded coastal and inland wetlands.

Why are coral reefs getting destroyed?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

How do humans threaten aquatic habitats?

Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.

How have human activities affected the world’s terrestrial and aquatic ecosystems?

Human effects on aquatic ecosystems can result from pollution, changes to the landscape or hydrological systems, and larger-scale impacts such as global climate change. … Increasing our understanding of aquatic ecosystems can lead to better practices that minimize impacts on aquatic environments.

How does population growth affect the ocean?

They play a significant role as both the world’s largest habitat and its climate regulator. However, the world’s oceans have suffered a lot at the hands of humans and population growth has increasingly compounded the problem by pushing oceans to their limits and altering ecosystems beyond their natural state.
