Pollution
What is air pollution?
This type of pollution is caused by the release of harmful substances into the air, often from vehicles or industrial processes.
What is carbon dioxide (CO₂)?
This gas, primarily produced by burning fossil fuels, is the most abundant greenhouse gas emitted by human activities.
What are safety goggles?
This type of personal protective equipment (PPE) is commonly worn to protect the eyes from flying debris, chemicals, or bright lights.
What is coal?
This non-renewable resource is primarily used for energy production and is often extracted through mining, leading to concerns over its depletion.
What is LED lighting?
This energy-efficient lighting source, commonly used in homes and businesses, uses less power than traditional incandescent bulbs and lasts longer.
What are contaminants?
This toxic substance, often associated with water pollution, is found in heavy metals like lead and mercury, and can affect aquatic life and human health.
What is photosynthesis?
This natural process, through which plants and trees absorb carbon dioxide, is critical for regulating carbon emissions in the atmosphere.
What is high-visibility clothing?
This safety measure, commonly used in construction, involves workers wearing bright clothing or vests to ensure they are visible to others, especially in low-light conditions.
What is overfishing?
The process by which overfishing leads to the depletion of fish populations, threatening marine ecosystems and global food security.
What is an electric vehicle (EV)?
This alternative form of transportation reduces emissions and is powered by electricity rather than fossil fuels.
What is microplastic?
This plastic waste, which takes hundreds of years to break down, is commonly found in marine environments, harming marine life.
What are greenhouse gases?
These gases, including methane and nitrous oxide, are much more effective at trapping heat in the atmosphere than carbon dioxide, even though they are present in smaller quantities.
What is safety culture?
This concept refers to creating a workplace culture where health and safety are prioritized by both employers and employees, often through regular training and open communication.
What is lithium?
This resource, used to manufacture products like electronics and batteries, is at risk of depletion due to high demand and limited global supplies.
What is solar energy?
This renewable energy source harnesses the power of sunlight to generate electricity, often using panels installed on rooftops or in solar farms.
What is water pollution?
This term refers to the accumulation of harmful substances like oil, sewage, and chemicals in bodies of water, particularly affecting aquatic ecosystems.
What is wind energy?
This renewable energy source produces no direct emissions and is often used to generate electricity through wind turbines.
What is hazard prevention and control?
This approach to workplace safety involves identifying and addressing hazards before they cause harm, often through proactive inspections, risk assessments, and employee training.
What is peak oil?
This term refers to the exhaustion of oil reserves, which could lead to global supply issues and higher prices in the coming decades.
What is bioplastic?
This biodegradable material, derived from plants like corn or sugarcane, is often used as an alternative to petroleum-based plastics.
What is smog?
The term for the harmful combination of dust, smoke, and other pollutants in the air, often seen in urban environments, especially in cities like Beijing or Los Angeles.
What is global warming?
This phenomenon, caused by the accumulation of greenhouse gases in the atmosphere, leads to global temperature rise and is a major driver of climate change.
What is OSHA (Occupational Safety and Health Administration)?
This organization, established in 1971, sets and enforces workplace safety standards in the United States.
What is timber (or forest resources)?
This renewable resource, although technically replenishable, is at risk of depletion when it is consumed faster than it can regenerate, particularly in the context of forests.
What is sustainable agriculture?
This farming method involves rotating crops and using organic materials to enrich the soil, reducing the need for synthetic fertilizers and promoting long-term soil health.
