You are probably scratching your head upon reading the title. How does an industry that thrives on taking down trees actually help the environment? It does not seem possible. Logging destroys forests, it does not help them or the environment.
The reality is much different. Logging is a business just like any other. If they were to remove all of their resources, they would go under in a short period of time. This is economics 101. A business must have something to sell in order to make money. A logging company cannot keep taking out trees at an unchecked rate and hope that there will be something to harvest down the road. Instead they use conservation techniques to keep their business alive.
It starts when a stand of trees is cut down. There is now nothing to hold the soil from eroding, which in turn creates problems such as mudslides. It also becomes more difficult for plants to gain a foothold as a rainfall can cause the soil to be washed away. To stop this from happening, private industries and government agencies employ re-foresters. These employees go into a harvested area and plant seedlings to prevent the soil from eroding. It also restores the habitat of the animals that was lost by logging. Over time these trees will be harvested again, but the cycle will always stay steady.
Villifying the logging industry is very easy to do. After all, they have an material tht is in constant demand, requiring a steady stream of trees. But the industry works with conservation efforts of all kinds, ensuring that habitats are there to stay for good. Loggers are most aware of the impact they have on the environment.
