Dear sir,
DEFORESTATION IN OSOSA VILLAGE
Through your esteemed newspaper, I would like to express my concern about the rapid deforestation in my community. It was estimated by the Nigeria Forestry Department that about 100,000 trees had been cut illegally cut without any replacement from the forest reserve in Ososa this year. This alarming thrend needs to be urgently curtail to avoid further effects of global climate change in our community and the country at large. This preliminary effect of this practice is well captured in the UN July report of places prone to flooding, which rank Ososa among the first 50 places in the world with high tendency of flooding.
I humbly request you use your good position to give this issue a wider coverage considering the brutal effect it will have on the economic and social development of our society if not immediately curtailed.
Yours faithfully,
(your name).
