really very excellent art of toys.you showing difference kinds colour of toys ovviously its very mindblowing art post..i am appreciating your post... the impact of the transport sector on the environment needs to be controlled by looking at all aspects of the transportation system, from transportation system planning, transportation model, means, traffic flow patterns, types of vehicle engines and fuel used.The negative impact of this transportation system problem is the high levels of pollutants due to emissions discharges from motor vehicle fumes. This can be a serious threat if left alone, not only for the environment we live in, further this could lead to a decrease in public health status by outbreaks of respiratory diseases caused by air pollution.thanks to sharing for your great post of art..very well done.take care yourself and best of luck of your great work..may god bless you..my dear friend.. @velimir
