温暖化が進んだら地球に住む事は難しくなるかもって英語でなんて言うの？

"If global warming continues it will be difficult to live on earth." This explains that living on the earth will become difficult if global warming continues. "Living on earth will become difficult if global warming continues." This is another way of explaining that global warming will make living here difficult in the future.

The above are three different ways of saying the same thing and are interchangeable.

If something is difficult to do we also say it is 'hard' to do so you could say 'If global warming continues it might be difficult/hard to live on Earth' another way of saying this is 'It might be difficult/hard to live on Earth if global warming continues' these are both great ways to describe this

By saying 'eventually', it is made clear that I am talking about the future and the possibility of global warming continuing. However, I leave this as a possibility meaning that it may not continue. To make a claim that may or may not happen, it is not always necessary to say the word 'if', it just depends on how you say it.

The two sentences you see provided above are great ways to express to your listener that you believe it will be difficult to live on Earth if global warming continues. In the second sentence you will see the term go on. This means to continue. This is a term that we use in our everyday conversation and it would make a great addition to your vocabulary.

If something 'signals the end' then it means it is a precursor to a final event or end result. 'The defeat of the enemy in the air signalled the end of their dream of world supremacy.'

if global warming continues earth could be unable to sustain life or we may have an uninhabitable planet if the temperatures continue to rise due to global warming
