Human Impacts
This type of species can be surveyed and used to determine conditions of an ecosystem.
What is an indicator species?
This is what's POPs stands for.
What is Persistent Organic Pollutants?
These are the 3 Rs.
What is Reduce, Reuse, Recycle?
A living organism that causes an infectious disease.
What is a pathogen?
This is a common way lead can enter the human body.
What is through water pipes and paint chips?
This is how humans disrupt coral reef ecosystems.
What is warming the ocean via greenhouse emissions, bleaching coral, or overfishing?
These POPs are additives in paint and plastics released into the aquatic ecosystems by industrial wastewater. Toxic to fish and causes reproductive failure and cancer in humans.
What are PCBs?
These are cons of recycling.
What is costly and requires significant energy?
These are reasons why a country may experience higher rates of infectious diseases.
What is being less developed, having less sanitary waste disposal, having less access to healthcare, having a lack of treatment for drinking water, and being in a tropical climate?
This is the interaction of two or more substances to cause an effect greater than each of them individually.
What is synergism?
This type of pollutant comes from deforestation via runoff and causes the water to become more turbid.
What is sediment?
Ways POPs travel long distances.
What is wind and water?
This method involves organic matter being decomposed under controlled conditions.
What is composting?
This is a disease commonly found in sub-saharan Africa and spread through this vector. Flu-like symptoms.
What is malaria and mosquito?
This cancerous tumor is caused by exposure to asbestos and effects the lining of the respiratory tract, heart, and abdominal cavity.
What is mesothelioma?
These are effects of oil spills on organisms and their ecosystems.
What is decreased visibility, decreased photosynthesis, oil sticking to bird feathers, death via ingestion or suffocation, or oil settling deep in root structures of different habitats?
These POPs were widely used as an insecticide before it was phased out by many developed nations. Persists in soils and sediments in aquatic ecosystems and builds up in food webs.
These are the benefits of composting.
What is reduces landfill volume, produces rich organic matter, or reduces the amount of methane released?
This bacterial infection is caused by drinking infected water.
What is cholera?
This air pollutant worsens respiratory conditions like asthma and bronchitis. It's caused by car exhaust and coal combustion. (Photochemical breakdown of NO2)
What is tropospheric ozone (O3)?
The amount of free, oxygen gas in a water source. The more of this, the more organisms it can support.
What is dissolved oxygen (DO)?
This POP is often found food containers and water bottles and is used in the production of plastics and epoxy resins. It has an endocrine-disrupting effect.
What is BPA?
Using a metal water bottle instead of plastic water bottles is an example of this R.
What is reduce?
This bacterial infection targets the lungs and is spread by breathing in fluids of an infected person. Leading cause of death by disease in the developing world.
What is tuberculosis?
What is the stratosphere?
