Climate change alters temperature, precipitation patterns, and seasonal cycles, affecting plant growth and reproduction. It can shift habitats, making them unsuitable for some plants, and increase the frequency of extreme weather events that can further stress plant populations.

气候变化会改变温度、降水模式和季节周期，从而影响植物的生长和繁殖。它可能会改变栖息地，使其对某些植物变得不适合，并增加极端天气事件的频率，这会进一步给植物种群带来压力。 

Plants are crucial for the environment because they produce oxygen through photosynthesis, which is essential for most life forms. They also help regulate climate, support biodiversity, prevent soil erosion, and provide habitats and food for wildlife.

植物对环境至关重要，因为它们通过光合作用产生氧气，这对大多数生命形式都是必需的。植物还帮助调节气候，支持生物多样性，防止土壤侵蚀，并为野生动物提供栖息地和食物。

Pollution, such as air and water pollution, can harm plants by contaminating their soil and water sources. Pollutants can interfere with plant growth, reproduction, and overall health, and may lead to the decline of entire plant populations.

污染，如空气和水污染，可以通过污染土壤和水源来危害植物。污染物可能会干扰植物的生长、繁殖和整体健康，可能导致整个植物种群的衰退。

Botanical gardens and seed banks play a crucial role in plant conservation by preserving plant species through cultivation and seed storage. They also conduct research on plant species and their needs, provide education on plant conservation, and often participate in reintroduction efforts for endangered plants.

植物园和种子库在植物保护中扮演着至关重要的角色，它们通过栽培和储存种子来保护植物物种。它们还进行植物物种及其需求的研究，提供植物保护方面的教育，并经常参与濒危植物的重新引入工作。
