1. It’s a shame that solar energy can’t be produced at night.
2. If we continue destroying animals’ habitats, more and more species will go extinct.
3. A hundred years ago these fields were so fertile that they could easily feed the whole village.
4. I wouldn’t call that hazardous waste, but you shouldn’t put it in the ordinary trash can either.
5. I installed these new solar panels on my roof. This should cut down my electricity bill.
6. The smell of sewage is terrible! I wish they would build these drains somewhere else.
7.–8. Instead of burning fossil fuels, we should move towards renewable energy.
9.–10. To my knowledge, the Vatican was the first carbon neutral country in the world. Finland should follow its example, since climate change is a serious matter.
