32 Ecology, Biodiversity, Sustainability, Ecological impacts of human activities terms
Ecology is the study of the relationships between living organisms and their environment, and it is an important field of study because it helps us to understand how human activities can impact the natural world. By understanding the impacts of our actions on the environment, we can make informed decisions about how to use natural resources sustainably and protect the Earth's ecosystems.
Abiotic

Conserve
Verb
To use resources wisely and without waste.
Example: By turning off lights when we leave a room and using energy-efficient appliances, we can conserve energy and reduce our carbon footprint.
fr: Conserver
Deforestation
Noun
The removal of forests, which can contribute to climate change through the release of stored carbon and the reduction of carbon sequestration.
Example: Deforestation can contribute to climate change by releasing stored carbon and reducing the ability of forests to absorb carbon dioxide from the atmosphere.
fr: Déforestation
Eco-friendly
Adjective
Designed or produced in a way that is environmentally friendly or sustainable.
Example: The eco-friendly packaging of the product is made from recycled materials and is fully recyclable
fr: Respectueux de l'environnement
Ecosystem
Noun
A community of living organisms and their physical environment, functioning as a unit.
Example: The grassland ecosystem is characterized by grasses and other herbaceous plants, as well as a variety of animal species.
fr: Écosystème
Environmental
Adjective
Relating to or concerned with the protection of the natural world and the impact of human activities on it.
Example: The environmental impact of burning fossil fuels is a major concern, as it contributes to climate change and air pollution.
fr: Environnement
Extreme weather
Noun
Unusually severe or unusual weather events, such as heatwaves, droughts, and storms, which may be more frequent or intense as a result of climate change.
Example: Extreme weather events, such as heatwaves and droughts, can have serious consequences for human health and the environment, and climate change may increase the frequency and intensity of these events.
fr: Temps extrême
Fossil fuels
Noun
Non-renewable energy sources, such as coal, oil, and natural gas, that release greenhouse gases when burned.
Example: Fossil fuels are a major contributor to global warming, as the burning of these energy sources releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere.
fr: Les combustibles fossiles
Green
Adjective
Relating to the protection of the natural environment and the promotion of sustainable practices.
Example: The company's green initiatives, such as reducing energy use and recycling waste, demonstrate their commitment to protecting the environment.
fr: Vert
Greenhouse effect
Noun
The process by which the Earth's atmosphere traps heat, causing the planet to warm.
Example: The greenhouse effect is a natural process that helps to keep the Earth's surface warm, but an increase in greenhouse gases such as carbon dioxide can lead to an increase in global temperatures.
fr: Effet de serre
Habitat
Noun
The place where an organism or community of organisms lives.
Example: The habitat of the orangutan is the tropical rainforest, where it can find food, shelter, and the resources it needs to survive.
fr: Habitat
Ocean acidification
Noun
The process by which the oceans become more acidic as they absorb increasing amounts of carbon dioxide from the atmosphere.
Example: Ocean acidification can have negative impacts on marine life, as the increased acidity of the water can disrupt the ability of some species to grow and reproduce.
fr: Acidification des océans
Organic
Adjective
Relating to or derived from living matter, such as plants or animals.
Example: The organic produce at the farmers market is grown without the use of synthetic pesticides or fertilizers.
fr: Biologique
Overconsumption
Noun
The excessive use of natural resources, often leading to waste and environmental degradation.
Example: Overconsumption is a major contributor to environmental degradation, as it can lead to the depletion of natural resources and the generation of large amounts of waste.
fr: Surconsommation
Ozone layer
Noun
A layer of gas in the Earth's atmosphere that protects the planet from harmful ultraviolet radiation.
