If more people used the public transport would it be better for the environment or worse?

It would be better for the environment because a normal car can only fit 5 passengers but on the otherside, a bus can fit about 50 passengers.
You will usually get different answers from different people depending on what they believe to be true and whether or not they believe what politicians have been telling them.

It has been discovered on more than one occasion and as recent as 2010 that scientists that were appointed to investigate whether or not human pollution has any impact on our global environment have altered their data from the truth to make it appear that humans are damaging the environment.

What I and many others believe is that based on the true data of the appointed scientists that global warming and other environmental impacts is a natural occurrence in nature and not caused by humans or their machines. The Earth has warm periods and cool periods and this what their data truly shows but certain politicians have an agenda to raise money for the government by using scare tactics that humans are responsible for damaging our environment through CO2 gases and other pollutants in order to charge taxes or impose restrictions on certain industries and even exploit other industrial countries.
