Environmental Impact of Bottom Trawling

Play an AI-generated podcast conversation about this lesson

Match the following researchers with their opinions on the carbon impact of trawling:

Trisha Atwood = Believes around 55% of CO2 released by trawling ends up in the atmosphere Peck = Advocates for reducing trawling to protect marine ecosystems Gareth Cunningham = Calls for urgent measures to reduce the carbon impact of bottom-towed fishing gear Jan Geert Hiddink = Is sceptical about the estimates of CO2 released by trawling

Match the following percentages with their corresponding global emissions contributors in 2023:

0.8% = Trawling 2.8% = Aviation and shipping Unknown % = Carbon released from hard-to-break-down forms in seabed

Match the following statements with their corresponding assertions:

Atwood's team estimate = Based on actual measurements from studies on CO2 release from trawled seabeds Hiddink's argument = Claims that much of the carbon on seafloor is in hard-to-break-down forms, not released by trawling Conservationists' stance = Supports reducing trawling to protect marine habitats and ecosystems Cunningham's call = Urges for a ban on trawling in marine protected areas to reduce carbon impact

Match the following terms with their meanings as used in the text:

Just transition = Transition to reduce environmental impact while ensuring social justice Marine protected areas = Designated areas where fishing activities are restricted or banned Seafloor sediments = Materials settled at the bottom of the ocean floor Bottom-towed fishing gear = Fishing equipment that is dragged along the seafloor Signup and view all the answers

Match the following organizations with their advocacy related to trawling:

Global Fishing Watch = Provides data on the extent of trawling worldwide Marine Conservation Society = Calls for a ban on trawling in marine protected areas around the UK Utah State University = Conducted studies on CO2 release during trawling Bangor University = Expresses skepticism about estimates of CO2 release by trawling Signup and view all the answers

Match the following terms with their corresponding descriptions:

Bottom trawling = Involves dragging weighted nets across the seafloor to catch bottom-dwelling fish and shellfish CO2 emissions from bottom trawling = Release around 340 million tonnes of carbon dioxide into the atmosphere each year Impact of bottom trawling on marine habitats = Destroys habitats that can take many years to re-establish and recover Role of sediments in bottom trawling = Provide oxygen for microbes to break down organic matter into carbon dioxide Signup and view all the answers

Match the following consequences with their causes:

Damage to cold water reefs = Caused by the fishing gear used in bottom trawling Stirring up sediments = Provides oxygen for microbes, leading to the release of carbon dioxide Preservation of organic matter in sediments = Due to low-oxygen conditions preventing decomposition Effective locking away of carbon = Prevented by stirring up sediments during bottom trawling Signup and view all the answers

Match the following statements with their related facts:

Global impact of bottom trawling emissions = Nearly 1 per cent of all global CO2 emissions Duration for marine habitats to recover after bottom trawling = Many years Expert opinion on bottom trawling's destructiveness = 'Bottom trawling is an extremely destructive form of fishing' - Mika Peck Alternative fate of sediments if not stirred up = Continuing to build up for many millennia Signup and view all the answers

Match the following terms with their associated effects:

Controversy surrounding bottom trawling = Due to its damaging effects on seafloor environments Contribution of sediments to carbon dioxide release = Sediments provide oxygen for microbes to break down organic matter Role of fishing gear in marine habitat destruction = Damages habitats like cold water reefs during bottom trawling Locked away carbon due to low-oxygen conditions = Prevents organic matter decomposition in sediments Signup and view all the answers

Match the following descriptions with their corresponding practices:

Widely used fishing practice involving nets and weights = Bottom trawling Technique involving dragging nets across seafloor for fishing = Bottom trawling Destructive fishing method impacting marine ecosystems = Bottom trawling Practice releasing significant CO2 emissions annually = Bottom trawling Signup and view all the answers
