What are two primary ways the transport sector contributes to climate change?
What are two primary ways the transport sector contributes to climate change?
The transport sector contributes to climate change through air pollution from fossil fuel combustion and habitat fragmentation that disrupts ecosystems.
How does habitat fragmentation affect wildlife, and what are two characteristics of vulnerable species?
How does habitat fragmentation affect wildlife, and what are two characteristics of vulnerable species?
Habitat fragmentation affects wildlife by converting natural habitats into pavement, making it harder for species to thrive. Vulnerable species may have larger area needs and low reproductive rates.
Explain how road construction can create both benefits and harms for wildlife populations.
Explain how road construction can create both benefits and harms for wildlife populations.
Road construction can benefit edge-dwelling species by creating new habitats but harms interior species by reducing available habitat and increasing edge effects.

Study Notes
Transport Sector Impacts
- Impacts include air pollution, habitat fragmentation, noise pollution, water pollution, and climate change.
Air Pollution
- Transport contributes to air pollution due to incomplete combustion in internal combustion engines.
- Imperfect combustion of fossil fuels in cars produces air contaminants.
- Emission levels depend on vehicle characteristics, driving habits (e.g., speed, congestion), and atmospheric conditions (e.g., weather).
- Though primary pollutant emissions have decreased due to fuel-efficient vehicles.
Habitat Fragmentation
- Road construction and expansion fragment habitats by converting natural areas to pavement and clearing roadside vegetation.
- Wildlife with larger habitat needs, low densities, low reproductive rates, and wide-ranging movements are particularly vulnerable.
- Fragmentation creates forest edges, which can benefit edge-dwelling species but harm interior species by reducing available habitat.
- Habitat fragmentation strategies exist, including avoidance, mitigation, and compensation.
Water Pollution
- Impermeable surfaces in transport infrastructure (e.g., roads) lead to increased runoff and pollution entering waterways and sewage systems.
- Runoff carries pollutants from oil, rubber, and other sources.
Climate Change
- Transport plays a role in climate change through mitigation (reducing emissions) and adaptation (building resilient infrastructure).
