How Overground and Underground Transportation Impact Environment
Transportation is a major contributor to environmental pollution. Every mode of transportation has its own impact on the environment. Both overground and underground transportation have their own advantages and disadvantages when it comes to environmental impact.
- Noise pollution: Overground transportation creates noise pollution which can be harmful to human health and also disturbs the local wildlife. Underground transportation, on the other hand, creates less noise pollution. Due to the nature of the environment, the sound generated in underground trains is absorbed and does not travel far.
- Air pollution: Overground transportation creates more air pollution due to the emissions from the vehicles. Underground transportation, on the other hand, is electric and produces zero emissions.
- Land usage: Overground transportation requires more land for construction of the tracks and stations. This can lead to deforestation and loss of natural habitats. Conversely, underground transportation requires less land, and any land that is used can be restored back to its natural state after construction.
When comparing overground and underground transportation, it is important to consider the environmental impact of both modes of transportation. While underground transportation seems to have advantages in terms of noise and air pollution, it may not be the best option in terms of cost and construction. It is up to policymakers to weigh the benefits against the costs and choose a mode of transportation that is most suitable for their specific city or region.
Carbon Footprint
One of the most significant ways overground and underground transportation impact the environment is through their carbon footprint. Overground transportation is responsible for around 15% of global CO2 emissions. The use of diesel and gasoline engines in overground transportation leads to a significant carbon footprint. Underground transportation, on the other hand, has zero emissions, making it a more environmentally friendly option.
Comparison Table of Environmental Impact
| Environmental Impact | Overground Transportation | Underground Transportation |
