改變原生動物棲地
Invasive plants are any species of plant that are intentionally or accidentally introduced into regions outside of their native habitats by human activities.
入侵植物是經由人類活動而被有意或意外地引入原生地以外地區的植物品種。
habitat (n.)棲息地；inhabit (v.)居住；habitant (n.)居民
As unwanted aliens, invasive plants can spread quickly in new areas and negatively impact native species as well as other aspects of the environment.
作為不受歡迎的外來者，入侵植物會在新地區快速蔓延並為當地物種和環境的其它層面帶來負面衝擊。
alien (n.)外來者、外國人impact (v.)影響、衝擊aspect (n.)層面、方面
First, invasive plants can affect biodiversity.
首先，入侵植物會影響生物多樣性。
diversity (n.)多樣性；cultural diversity 文化多樣性；racial diversity 種族多樣性
Not only can they displace native plants and prevent their growth, but they can also create monocultures, by greatly reducing the diversity of other plants.
它們不僅排擠原生植物的生存空間並妨礙生長，也會透過減少其它植物的多樣性，而形成單一物種區。
not only… but also… 不只……而且還……displace (v.)迫使離開原位monoculture (n.)單一種植（養殖）區
Additionally, the quality of water and soil can be damaged by alien species.
此外，水分和土壤的品質也會被外來物種破壞。
alien (adj.)外來的、外國的
The root systems of some plants can cause more soil erosion that leads directly to decreased water quality in the area.
有些植物的根莖系統比較會侵蝕土壤，直接導致該地區水質降低。
erosion (n.)侵蝕、腐蝕；erode (v.)侵蝕、腐蝕decrease (v.)減少、降低
In relation to farming, invasive plant species can also affect the cultivation of crops, leading to higher prices for food as more money is spent by farmers to control the invasion of non-native plants.
農業方面，入侵植物品種可能影響作物的耕作，因為農夫要花更多成本控制外來植物的入侵，導致糧食價格上漲。
in relation to sth. 關於agriculture (n.)農業lead to 導致
In any environment, the overall effects of invasive species can also reduce native animal populations by changing the quality of food and water sources as well as areas for shelter.
在任何環境中，入侵品種的整體影響也會減少原生動物的數量，這是因為糧食和水源品質以及棲息地的變化。
population (n.) （動植物）總量、人口
In some places, these negative impacts can even be extremely dangerous, creating conditions that increase the risk of wildfires, which has been of great concern to humans in recent years.
在某些地方，這些負面的衝擊甚至極為危險，創造使野火風險提高的條件，這在近幾年對人類來說是一大隱憂。
risk (n.)風險、危險；at risk 處於危險或風險中be of (great) concern 令人擔憂的、很重要的
