One Kilometre Walk to School

Why don't we walk to school instead of driving our car and drop our child right in front of school's gate?
We contribute to the climate change, global warming, green house effect, air pollution, traffic jam, disturbing people, block pedestrian, double parking and many more.
If our house about one kilometre from school, we can walk. In new urban housing areas, the distance from school and house is near compared to rural areas. Why we must joint the traffic jam, burn petrol, release poisonous smoke, heated school area and wasting our time. May be in certain area 200-300 m from school walking is faster than using cars.
IF YOUR HOUSE IS ONE KILOMETRE FROM SCHOOL PLEASE WALK. LOCAL AUTHORITY PLEASE PROVIDE NECESSARY FACILITIES TO SUPPORT ONE KILOMETRE WALK TO SCHOOL CAMPAIGN.
Remember! Do you have two trees which their trunks are as big as your body to supply your own oxygen. If not, please realise that you are sharing oxygen with others or stealing others.
