Bioindicators
Organisms that reflect the health of their environment.
What are bioindicators?
This is what bioindicators tell us about an ecosystem.
What is the health f the ecosystem?
Refers to long-term shifts in temperatures and weather patterns
What is climate change?
____are mainly responsible for global warming
What are humans?
Is a renewable power source that comes from the natural movement of water, including waves, tides and ocean currents.
What is renewable energy?
Bioindicators are compared to tiny detectives.
Why they provide clues about the state of the environment?
This is how top predators like eagles and wolves indicate the health of the food web.
What is by their population levels?
There are two natural causes of climate change.
What are changes in the sun’s activity or large volcanic eruptions?
Climate change can affect all these.
What is our health, ability to grow food, housing, safety and work?
It uses the movement of tides to generate electricity.
What is Tidal energy?
Indicates an abundance of algae in a lake.
What is an excess of nutrients from agricultural runoff?
Canaries are considered early warning systems.
What is they are highly sensitive to gases and would become sick or die before humans could detect them?
Human activities that have been the main driver of climate change since 1800s.
What is the burning of fossil fuels like coal, oil and gas?
The consequences of climate change now include, among others:
What are intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity?
It captures power from ocean waves to produce energy
What is wave energy?
This is how bioindicators species alert us of environmental problems.
What is by their presence, absence, or changes in population?
Bioindicators are considered cost-effective tools for environmental monitoring, because.
What is they providing a quick snapshot of environmental conditions?
It generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.
What is burning fossil fuels?
These are among the main sectors causing greenhouse gases.
What is energy, industry, transport, buildings, agriculture and land use?
Types of marine energy.
What is Tidal energy, Wave energy, Ocean thermal energy?
A decline in biodiversity is a sign of this.
What is a decline in ecosystem health?
This is how bioindicators can be used to monitor the effectiveness of conservation efforts.
What is by tracking changes in population of threatened species?
The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others. The six biggest emitters are.
What is China, the United States of America, India, the European Union, the Russian Federation, and Brazil?
We have global frameworks and agreements to guide progress, such as the Sustainable Development Goals, the UN Framework Convention on Climate Change and the Paris Agreement. Three broad categories of action are:
What are cutting emissions, adapting to climate impacts and financing required adjustments?
It is considered a predictable and clean source of energy, though it can be challenging to implement due to the harsh marine environment.
What is Wave energy?
