HC & Plastic Pollution
What is the impact of human activity on public health (or environmental impact)?
Human actions like waste disposal and industrial processes can negatively influence both ecosystems and human well-being.
What is agricultural runoff?
This process occurs when rainwater carries fertilizers and chemicals from farms into nearby water systems.
What is coral bleaching?
Corals expel the organisms that give them color and essential nutrients due to stress from changing conditions.
What are microplastics?
Tiny plastic particles are found in ocean water, seafood, and even drinking water
What is biodiversity?
The variety of life in ecosystems
What is oil dumping (or oil spills)?
An activity that introduces petroleum into marine environments, where it can coat organisms, disrupt oxygen exchange, and damage entire aquatic ecosystems.
Marine organisms abandon a region where oxygen levels have dropped so low that survival is nearly impossible is known as?
A dead zone
What happens if corals die?
Marine life loses habitat
A small fish absorbs pollutants from its environment, which remain stored in its body over time rather than being broken down or excreted. Also known as?
bioaccumulation
This irreversible process occurs when a species can no longer survive in its environment due to factors like habitat destruction and climate change. Is known as?
species extinction
What is plastic pollution (or improper plastic disposal)?
An environmental issue that involves materials that resist decomposition, often breaking into smaller particles that can be ingested by marine life and enter the food chain.
What is cover cropping?
Farmer plants crops during the off-season not to harvest them, but to improve soil quality and reduce the need for chemical inputs
What is one way we can prevent coral bleaching?
Reduce greenhouse gas emissions
A top predator contains significantly higher concentrations of toxins than the smaller organisms it consumes, due to repeated transfer through the food chain. Also known as?
biomagnification
What is climate change?
Rising global temperatures and shifting environmental conditions contribute to this large-scale driver of biodiversity loss.
What are the three plastic waste solutions?
Reduce single use plastic
Three R’s
Reduce, Reuse, Recycle
Speaking out
Fish in a coastal area begin to die off after a thick green layer spreads across the water’s surface, blocking sunlight and altering oxygen levels. What is this called?
What is an algal bloom
What are the names of the minerals we should use instead in our facial products?
zinc oxide / titanium dioxide
What can happen if a human digests toxins?
Death, contamination, e coli
Apart from reproduction, what else does pollution affect?
Survival
Food
etc
What is environmental responsibility
Responsibility calls for both individuals and industries to reduce harmful practices like oil dumping, plastic waste, and chemical pollution in order to protect ecosystems and human health.
How does it affect human health?
Food Chains get contaminated
Coral bleaching is mainly caused by?
Rising sea temperature levels
What age groups are more at risk of contracting E. Coli?
Young children
Seniors
People with compromised immune systems
What is Habitat Loss?
is the reduction or elimination of the natural environment where species live, reproduce, and thrive, primarily caused by human activities.
