Study Notes
Environmental Impacts of Road Development
- Clearing natural vegetation for road construction leads to soil erosion, increasing sedimentation in streams and rivers, and raising water levels, which can cause flooding.
- Road development fragments forests, reducing animal habitats and restricting animal movement, resulting in roadkill when animals attempt to cross busy roads.
- Alterations to landforms, such as levelling mountains and diverting river channels, occur during road construction.
Contribution to Climate Change
- The transport system, which relies on energy sources like electricity, petroleum, or biofuel, produces carbon dioxide and other greenhouse gases when petrol is burned.
- These emissions contribute to the increase in the Earth's temperature.
Environmental Impacts of Road Development
- Natural vegetation clearance for road construction leads to soil erosion, causing sediments to enter streams and rivers, increasing water levels and flooding risks.
- Road development fragments forests, reducing animal habitats and restricting animal movement, leading to roadkill when animals attempt to cross roads.
- Fragmentation of forests also results in population isolation, inbreeding, and reduced biodiversity.
Changes to Topography and Terrain
- Road construction involves modifying landforms, such as levelling mountains and diverting river channels.
- These changes alter the natural landscape, potentially disrupting natural ecosystems and habitats.
Contribution to Climate Change
- The transport system relies on energy sources like electricity, petroleum, or biofuel, which produce carbon dioxide and other greenhouse gases when burned.
- The combustion of petrol specifically contributes to the increase in the Earth's temperature, exacerbating climate change.
- The overall carbon footprint of road development and transportation contributes to global warming.
