As the main body of renewable natural resources and terrestrial ecosystem, trees play an irreplaceable role in the history of human survival and development.
Conclusion: The crisis of trees is mainly caused by human beings. With the growth of population, agricultural land is expanding and a large number of trees are cut down. A lot of logging makes trees less and less. According to the statistics of FAO, at present, more than 20 hectares of forests are destroyed every minute on the earth, so many trees are destroyed. From 1950 to 1985, the forest area in the world has been reduced by half in just over 30 years. Environmental pollution caused by human activities has also brought disasters to plants. Therefore, protecting trees should be everyone's responsibility.
