I left out the following sentences. Could you please check them?

1) Colin decided to try to become a real eco-warrior and reduce his family's impact on the environment (I need a synonym for impact).
2) For one year in his familiy there wasn't a TV or a fridge, they used one electric light to save electricity.
3) They didn't buy any factory-made bottles of shampoo, rolls of toilet paper or bars of soap. They either made them or used alternatives instead.
4) They also tried to create less rubbish and use less fuel. They travelled by bicycle and bought second-hand things for their apartment.
5) They carried food in baskets instead of (rather than??) plastic bags. They avoided takeaway food so they didn't didn't have to throw away all the containers that it comes (came in?).
6) Though the experiment was tough, when they finished it they were fitter, happier and a little bit wiser.

1) Colin decided to try to become a real eco-warrior and reduce his family's impact on the environment (I need a synonym for impact).

- To find a synonym for "impact," you can use the term "effect" or "influence" instead. So the revised sentence would be: "Colin decided to try to become a real eco-warrior and reduce his family's effect on the environment."

2) For one year in his family, there wasn't a TV or a fridge, they used one electric light to save electricity.
- The sentence is grammatically correct, but if you want to enhance clarity, you could add "they" before "didn't" in the second part. So, the modified sentence would be: "For one year in his family, they didn't have a TV or a fridge; they used only one electric light to save electricity."

3) They didn't buy any factory-made bottles of shampoo, rolls of toilet paper, or bars of soap. They either made them or used alternatives instead.
- The sentence is accurate, and no changes are necessary.

4) They also tried to create less rubbish and use less fuel. They traveled by bicycle and bought second-hand things for their apartment.
- The sentence is grammatically correct.

5) They carried food in baskets instead of (rather than??) plastic bags. They avoided takeaway food so they didn't have to throw away all the containers that it comes (came in?).
- "Rather than" is an appropriate alternative to "instead of." In the second part, you can use "came" instead of "comes" since it refers to the past tense. The revised sentence would be: "They carried food in baskets rather than plastic bags. They avoided takeaway food so they didn't have to throw away all the containers that it came in."

6) Though the experiment was tough, when they finished it they were fitter, happier, and a little bit wiser.
- The sentence is accurate, and no changes are necessary.
