We need to use fossil fuel to drive a car. And when we use fossil fuel, CO2 is emitted, which causes global warming by increasing the greenhouse effect. Also, to make a road for cars we sometimes cut the trees. It decreases the number of trees that can change CO2 to oxygen. The habitat for animals, plants and insects is also limited. And it decreases the number of organisms and they can even be extincted weakening the eco system. It decreases the resilience of earth for global warming. So I think there is a relationship between global warming and cars.

Hello, Seong Eun!

Thanks for writing your homework.
Good points you shared. Great work! ^^ 
See you tomorrow~

We need to use fossil fuel to drive a car. And when we use fossil fuel, CO2 is emitted, which causes global warming by increasing the greenhouse effect.

>> Correct!

OR: We must use fossil fuels to drive our cars. And using fossil fuels emits CO2, which contributes to global warming by increasing the greenhouse effect.

Also, to make a road for cars we sometimes cut the trees. It decreases the number of trees that can change CO2 to oxygen. 

>> Correct!

OR: We also cut trees to make roads for cars. It reduces the number of trees that convert CO2 to oxygen. 

The habitat for animals, plants and insects is also limited. 

>> Correct!

OR: There is a limited amount of habitat for plants, animals, and insects. 
And it decreases the number of organisms and they can even be extincted weakening the eco system. It decreases the resilience of earth for global warming. 

>> Correct!

OR: It also reduces the number of organisms and may even cause them to become extinct, weakening the ecosystem. It weakens the earth's capacity to global warming. 

So I think there is a relationship between global warming and cars.

>> Correct!

OR: So, I believe there is a link between global warming and cars.
