The practice of fishing so much that the breeding population of fish becomes depleted, threatening marine ecosystem balance.
overfishing
15
The lack of sufficient available water resources to meet the demands of water usage within a region.
water scarcity
15
The removal of the top layer of soil by natural forces like wind and water, often accelerated by human activities like deforestation and improper land use.
soil erosion
15
The process by which fertile land becomes desert, typically caused by climate change, drought, deforestation, and unsustainable agricultural practices.
desertification
15
The process where coral loses its vibrant colors and turns white due to stress from changes in temperature, ocean acidification, or pollution.
coral reef bleaching
15
The process by which natural habitats are rendered functionally unable to support the species present, often through human intervention.
habitat destruction
15
The large-scale removal of forests, typically through human activities like logging, agriculture, and urban development, leading to habitat destruction and climate change.
deforestation
15
Gases that absorb and emit radiation within the thermal infrared range, including carbon dioxide, methane, nitrous oxide, and water vapor.
greenhouse gases
15
The release of carbon dioxide and other carbon compounds into the atmosphere, primarily through burning fossil fuels, industrial processes, and deforestation.
carbon emissions
15
The ongoing decrease in the pH of the Earth's oceans, caused by the absorption of excessive carbon dioxide, which threatens marine ecosystems and biodiversity.
ocean acidification
15
The process of ice sheets in the Arctic and Antarctic regions losing mass due to rising global temperatures, leading to sea level rise and ecosystem disruption.
polar ice cap melting
15
A term describing the urgent and potentially catastrophic changes in global climate patterns caused by human activities, requiring immediate and comprehensive action.
climate crisis
15
A critical threshold where a small change can push a system into a completely different state, often with dramatic and potentially irreversible consequences.
tipping point
15
The process by which green plants and other organisms convert sunlight into chemical energy stored in glucose or other sugars.
photosynthesis
15
Natural resources that cannot be readily replaced once consumed, such as fossil fuels, minerals, and metal ores.
non-renewable resources
15
Natural resources that can be replenished naturally within a human lifetime, such as solar energy, wind, water, and biomass.
