(A) List some of the main human activities that contribute to Species extinction. (b) Do you think such activities can be justified?

Main human activities contributing to species extinction include habitat destruction through deforestation and urbanization, pollution, overfishing, and climate change caused by greenhouse gas emissions. While some activities, like agriculture and industry, are essential for human survival, their environmental impact often outweighs the benefits, leading to irreversible damage to ecosystems. Justifying these activities is complex; sustainable practices can mitigate harm, but prioritizing short-term economic gain frequently leads to long-term ecological consequences. Ultimately, a balance must be struck between human needs and the preservation of biodiversity.
