Biodiversity is very important for ecological balance.Not only does biodiversity support stable ecosys- tems,but also it provides resources like clean water and food for human survival.Every species,no matter how small,plays a role in the ecosystem.If one species disappears,it may break the balance. However,human activities like deforestation that threaten natur al habitats are harmful to ecolog- ical balance.When people cut down too many trees or pollute rivers,many animals lose their natural habitat.This can even lead to the extinction of some species. It is crucial for the Earth to maintain ecological balance,as it ensures the survival of all species. Compared with a disturbed ecosystem,a balanced one can better sustain life and resist natural disasters.So we must take measures to protect our environment. Although ecological balance is delicate,we can restore it by taking effective measures.We can plant more trees,stop polluting and protect endangered species.What matters most for environmental protection is to keep the balance between human needs and nature,living in harmony with the planet.Let's work together to keep the ecological balance for a better future. 5
