A modern dynamic person cannot imagine his life without traveling by plane. Being one of the fastest and safest transports they provide travelers with a possibility to reach destinations in extremely short time with the maximum of safety and convenient. However, the increase amount of aircrafts in the sky leads to serious pollution and spending of fuel resources, which are supposed to be resolved by restriction of air travel. Personally, I strongly believe, that these issues could be resolved by investment in energy efficiency and state regulation of fuel resources.
