Answer key — Ecology Quiz
- B. Paris AgreementThe Paris Agreement, signed in 2015, is an international treaty aimed at limiting global warming to well below 2°C, ideally to 1.5°C.
- A. Ozone layerThe ozone layer, located in the stratosphere, absorbs much of the UV radiation emitted by the sun, thereby protecting life on Earth.
- B. Anaerobic digestion (methanization)Anaerobic digestion is the process of breaking down organic waste in the absence of oxygen, producing biogas.
- A. Threat to marine lifePlastic waste in the oceans threatens marine life by entangling or poisoning it.
- B. Global warmingGlobal warming refers to the increase in average temperatures at Earth's surface, mainly caused by greenhouse gas emissions.
- A. Ocean Thermal Energy Conversion (OTEC)Ocean Thermal Energy Conversion harnesses the thermal gradient between warm surface water and cold deep water.
- C. Favor durable natural fiber clothing (linen, hemp)Natural fibers like linen or hemp have a much lower environmental impact than synthetic fibers.
- B. ThailandThailand is a leader in producing bioplastics from sugarcane and other renewable resources.
- A. Water filtration and biodiversityWetlands act as natural water filters and are home to a great diversity of species.
- A. Storm protection and biodiversityMangroves protect coastlines from storms and are home to a wide variety of marine and terrestrial species.
- C. Methane (CH₄)The sabotage of the Nord Stream pipelines released about 250,000 tons of methane, a greenhouse gas 28 times more powerful than CO₂ over 100 years.
- C. RussiaRussia has sharply increased its energy-intensive production of weapons and ammunition to sustain its war effort in Ukraine.
- D. ElectricIn France, thanks to a low-carbon energy mix (nuclear, renewables), electric vehicles emit less CO₂ per km.
- B. 3.5 tonsA diesel car emits about 2.6 kg of CO₂ per litre.
- A. The weight of the vehicleThe weight of the vehicle is the second most influential factor on fuel consumption, after driving style.
- C. Decreases consumption by 15 to 25%Good aerodynamics reduces air resistance, which can decrease fuel consumption by 15 to 25% at high speed.
- B. Metal and rubber particles, not filteredMetal particles (from brakes) and rubber particles (from tires) are not filtered by modern systems like the particulate filter (DPF), which only targets soot.
- A. Rising water temperatureWhen the water becomes too warm, coral expels the symbiotic algae (zooxanthellae) that give it its colour and most of its energy.
