Answer:
Dear people of London,
I am concerned greatly for our safety and would like to spread public awareness. Industrial development has been filling our rivers with toxic wastes that danger health for all. Mining activities have been leading to oil spills; furthermore, our sewage and waste water spills into the river as well as that oil. To prevent our river from being polluted, we need to take action by treating the wastes before discharging them. It is the only way we, as a community, can sleep sound and say, ¨Our water is pure and our health is content.¨
