Marigi worked deep in a forest in Nigeria，a country on the western coast of Africa.He is a logger who cuts down trees using a knife.The forest where he worked is in the Ondo State in Southwest Nigeria.But many trees in that forest have been lost to too much logging.
   The 61 -year-old father of two said that he could cut down over 15 trees anywhere in the forest，but he would be lucky to find only two now."During the time of my father，we had big trees but sadly what we have now are just small trees and we don't even allow them to grow tall enough before we cut them，" Marigi said.
   After cutting down the trees，Marigi puts markers on them to let other loggers know that he is the owner.The cut-down trees，or logs，are then transported（運(yùn)輸） by waterways and rivers to Nigeria's biggest city，Lagos.
   Trees in Nigeria are cut down to open land for farming or to feed the energy need of a growing population.From 2001 to 2021，Nigeria has lost 1.14 million hectares of tree cover.
   Months after cutting down the trees，Marigi returned to the forest to tie his 40 logs together so they could be transported.With other loggers，he paid for a boat to pull the logs through waterways from Ondo State to Lagos.
   They built simple houses on top of the logs to help protect themselves from the weather.Food was shared and they sang traditional songs to cheer themselves up.They did not sleep at night to make sure that the logs would not get away from the boat.The boat stopped at several places to pick up more loggers and their logs.A single boat can transport thousands of such logs.
   Marigi' s trip ended in Lagos where logs from Ondo State and other parts of the country came togejye.air.The logs were then cut and sold to users.
