Increase in Travel: We travel more and also unnecessarily sometimes. By this we contribute to air pollution directly. We go on tours round the world and even on long drives. This is was done even previously when the technology was low. But then the chances of pollution was meager. We relied on horses, camels and bulls for travel by road. By seas we relied on large boats and vessels. These methods of travel are time consuming but are less polluting. But current technology is so advanced that we travel from one part of the world to another in short time. This is great but has greater risk for human life and environment.
The pollution generated from these travels is huge. It is in the form of air, water and even noise pollution types. These pollutions poses health hazards.
Also there is lack of exercise and we develop sedentary habits.
