There are lots of things you could talk about here. Try to sit down and make a plan based around the following ideas:
Cars have an environmental impact, they are extremely damaging due to the fumes that they give off. This can have subsequent effects on nature and humans alike.
Cars cost taxpayers money because of the need to renew and build roads. If less cars use the roads then one can presume there would less damage to repair and indeed less roads required for society as a whole.
Cars can cause health problems if people breathe in noxious exhaust fumes. Thousands of people die every year due to air pollution. Cars and traffic have a massive impact on the air that we breathe every day.
Cars can be very dangerous and cause deaths every year. Car accidents account for a large number of fatalities around the world. Limiting car use would presumably lead to less deaths and less injuries to humans everywhere.
Yes, it is necessary to have a commitment for all the responsible parts of a society of ministers (in this case a Church Council), each one of them has responsibilities and rights so it’s very important to define which are the objectives to complete for each part and which is the decision level that they have inside of the organization, power is the most harmful tool in any organization so it’s very important to define the mean reason, why they are organizing a society, why they have people that wants to see them organized and what do they want to make, this will help to secure perpetual guardianship between each other’s and also will help to show to the follower people that they have convictions, strong and will help to develop a good connection.
For example, a Church Council has the role to administer the church according with the doctrine that they have and a doctrine has a connection between the spiritual and the actions that followers have to develop according with what is written by the ancestress, for example, The Bible, it’s not a contract but says what do you have to do and believe, if not, you can profess your religion according with your own doctrines and you can deviate the focus point of the church.
What speech? You need to be a bit more specific
