My name's......... nhập tên của mình.  Animal and plant extinction can ruin the ecosystem and reduce biodiversity. All creatures are part of an ecosystem. They all help humans in some way. For example, over 50% of the medicines currently in use are derived from natural products made from animals or plants. By losing biodiversity, we are losing the chance to discover new medicines that could save the lives of millions of people each year. What's more, nature is beautiful, and that's the best reason to preserve it. Walking in a rainforest or going scuba-diving over a coral reef helps us to relax and feel at peace.Hello everyone.thank you for listening.goodbye
