加劇全球暖化的重大問題
Wildfires are a type of natural disaster in which fires that are not planned and not able to be controlled spread through natural areas.
野火是一種自然災害，指的是沒有計劃、無法控制的火災在自然地區蔓延。
fire作「火」的意思時，為不可數名詞，作「火災」的意思時，則為可數名詞natural(adj.)自然的nature(n.)自然disaster(n.)災害disastrous(adj.)災害的、災難性的、悲慘的be able to可以uncontrolled, uncontrollable(adj.)不被控制的spread(v.)伸展、散布、傳播through(prep.)遍及
These unpredictable fires are not only dangerous to humans, animals, wild plants and crops but also to the Earth’s climate.
這些不可預知的火災不僅對人類、動物、野生植物和農作物造成危險，也對地球氣候造成危害。
unpredictable(adj.)無法預測的predict(v.)預言、預料e.g. He predicted that an earthquake was imminent.他預言即將發生地震prediction(n.)預言predictable(adj.)可預測的
For wildfires to start, there need to be three things: heat, oxygen and fuel.
野火發生需要三個條件：熱、氧氣和燃料。
heat(n.)熱能、高溫fuel(n.)燃料(v.)對…供給燃料、給…加油、刺激
In some cases, the causes of a fire are completely natural, like lightning striking, a volcano erupting or falling rocks creating sparks.
在某些情況下，火災的起因完全是自然的，比如閃電擊中、火山爆發或落石擦出火花。
ignite(v.)點燃、使燃燒erupt(v.)(火山等的)爆發eruption(n.)爆發spark(n.)火花、微量、絲毫e.g. He showed not a spark of interest in the plan.他對這個計畫一點不感興趣spark(v.)發出火花、閃耀
However, humans can also start wildfires accidentally with sparks from equipment, power lines, campfires, fireworks or cigarettes or intentionally by lighting fires to burn old crops or simply to destroy things.
然而，人類也可能意外地引發野火，如設備、電線、營火、煙火或香菸產生的火花，或者故意點火燒舊的作物或單純燒毀物品。
by accident意外地intentionally(adv.)故意地、蓄意地=purposely, deliberately, on purposeintention(n.)意圖
Once started, these fires can spread quickly by burning fuel, which can be dry or dead plants.
一旦起火，這些火會透過燒燃料（可能是乾燥或枯死的植物）迅速蔓延。
once(conj.)一旦
Windy and hot weather can also aid in spreading wildfires.
多風、炎熱的天氣也會助長野火的擴散。
aid(v.)幫助=help, assist
Because of this, drier conditions and higher temperatures caused by climate change in some areas have increased the danger of fires.
因此，氣候變遷在某些地區造成更乾燥的天氣條件和較高的溫度增加了火災的危險性。
consequently(adv.)因此
As for the effects, wildfires can kill animals, plants and people, destroy homes and businesses and create higher levels of air pollution.
至於影響方面，野火可能造成動物、植物和人類的喪生，摧毀住家和商家，並造成更嚴重的空氣污染。
as for至於regarding(prep.)關於effect(n.)影響
In fact, the amount of greenhouse gases produced by wildfires can also contribute to climate change.
事實上，野火產生的溫室氣體量也會導致氣候變遷。
in fact事實上=as a matter of factcontribute to貢獻、促成、導致result in導致
This not only makes such fires a huge problem for adding to global warming but also increases the risk of similar disasters.
這不僅使野火成為加劇全球暖化的重大問題，也提高了類似災害的風險。
risk(n.)風險risky(adj.)危險的、有風險的
