use bicycle save Petrol

Dear friends,
petrolium prises are rising day by day. but no. of vehicles are also rising rapidly but no one cares about petrol prises while increasing no. of vehicle increased air pollution and sound pollution as well. which is also responsible for global warming.
its also effects national economy.

so, friends its my request to all of you please use bicycle instead of motorised vehicle for your nearby works and try to use public conveyence for other works.

thanks
