What are the negative effects of transportation?
The potential negative impacts of transportation on environment can be listed as degradation of air quality, greenhouse gas emissions, increased threat of global climate change, degradation of water resources, noise and habitat loss and fragmentation.
Why public transport is better than private transport?
Using public transport is much less taxing on the environment compared to private vehicles. Since a lot of people can ride the same vehicle, the carbon emissions per head are largely reduced. Electrically powered transportation like the LRTs and KTMs are also friendlier to the environment than gas-guzzlers.
Why cars are bad for the environment?
Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States’ total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
