英文小作文：

Defoliation is a natural process that occurs when plants lose their leaves due to various reasons such as weather conditions or pests. However, human activities can also cause defoliation, such as using chemicals to defoliate crops or using machinery to clear forests and grassland for development or construction purposes.

Defoliation can have negative impacts on ecosystems and biodiversity, leading to changes in habitats and reducing biodiversity. Therefore, it is important to take measures to minimize defoliation and protect ecosystems and biodiversity.

In conclusion, defoliation is a natural process that occurs in nature, but it can also be caused by human activities. Defoliation can have negative impacts on ecosystems and biodiversity, so it is important to take measures to minimize its occurrence and protect our environment and biodiversity.
