a. Ben: Oh, sorry. I will just take a photo instead.

b. Lucy: Please don't! We should leave nature as we found it.

c. Ben: Look at those beautiful wild orchids! I want to pick one.

a. Ryan: Oh, I didn't know that, I will keep my food in my bag then.

b. Ryan: Look at those cute monkeys, can I give them some of my snacks?

c. Emma: No, feeding wild animals is strictly forbidden in this eco-park.

a. Alex: There are no bins around here. What should I do with this wrapper?

b. Alex: Good point. We shouldn't litter in the national park.

c. Chloe: Just keep it in your backpack until we get back to town.

a. Paul: You are right. I need to be more careful too.

b. Susan: To save water, of course. Every drop counts in this dry area.

c. Paul: Why are you turning off the tap while brushing your teeth?

a. Jack: Planting trees was the best part of our trip, wasn't it?

b. Jill: Absolutely! It felt great to give something back to nature.

c. Jack: I agree. Let's join another eco-tour next summer.

a. Chloe: Because respecting their traditions helps us build a better relationship with the community.

b. Sam: Why is it important to learn about local customs before we travel?

c. Sam: You are right, I will read a book about their culture tonight.

a. David: Let's rent bicycles to explore the national park instead of taking a taxi.

b. David: Exactly, and we can also stop anywhere we want to take photos.

c. Sarah: That is a great idea, it will help us enjoy the fresh air and reduce pollution.

a. Olivia: Yes, that's why tourists should always bring their own reusable water bottles.

b. Jack: I completely agree, small actions like that can save the environment.

c. Jack: It is very sad to see plastic bottles floating in this beautiful lake.

a. Leo: What eco-friendly items are you packing for our jungle trek?

b. Leo: Great choices, I will pack the same things to minimize our impact.

c. Grace: I am bringing a solar charger, a reusable straw, and some natural soap.

a. Mary: Let's visit the elephant rescue center to see them naturally.

b. John: Should we go on the elephant riding tour?

c. John: Really? Then what should we do instead?

d. John: That sounds much better. Let's book that one.

e. Mary: No, I heard those tours can be harmful to the animals.

a. Peter: This butterfly specimen looks so beautiful. I want to buy it.

b. Peter: I didn't think about that. I just wanted a nice souvenir.

c. Mary: Please don't. Buying insect specimens encourages catching wild ones.

d. Peter: That is a great alternative. I will do that.

e. Mary: You can buy a painting of a butterfly from a local artist instead.

a. Jack: Wow, thanks for telling me. I will keep my hands to myself.

b. Jack: I thought they were just colorful rocks under the sea.

c. Jack: Can I touch the coral reefs while we are snorkeling?

d. Jill: No, and touching them can actually kill them.

e. Jill: Absolutely not. Corals are very sensitive living animals.

a. Lucy: We really shouldn't step off the marked trail.

b. Ben: Let's take a shortcut through these bushes to reach the lake.

c. Ben: But it will save us at least twenty minutes!

d. Ben: Fair enough. We will stick to the main path then.

e. Lucy: Yes, but we might step on rare plants or disturb insect homes.

a. Alex: Oh dear. I will keep the bread for my lunch instead.

b. Alex: Why not? Bread is harmless, isn't it?

c. Chloe: The guide said we shouldn't feed them any human food.

d. Alex: I brought some bread to feed the fish in the pond.

e. Chloe: It actually pollutes the water and makes the fish sick.

a. Mark: Let me see. Oh, it says "reef-safe" right here!

b. Lisa: Is your sunscreen safe for the coral reefs?

c. Mark: I am not sure. I just bought it from the supermarket.

d. Lisa: Check the label. Normal ones have chemicals that damage corals.

e. Mark: I need to put on some sunscreen before we go into the sea.

a. Tom: That is a fair point. I should probably pack mine too.

b. Tom: But carrying it around all day seems a bit inconvenient.

c. Anna: It is my reusable water bottle to avoid buying plastic ones.

d. Anna: It might be, but it saves money and protects the environment.

e. Tom: Why are you packing that heavy metal bottle for our trip?

a. Lisa: We shouldn't do that. A responsible eco-tourist always stays on the path.

b. Lisa: Because stepping on the plants can damage the delicate soil and insects.

c. Mark: Let's walk into that beautiful flower field to take some pictures.

d. Mark: I didn't think about that. Let's just take photos from here.

e. Mark: Why is it so strict? It is just a quick photo.

a. Chloe: It cools down quickly. Eco-tourists should always save electricity in hotels.

b. Jack: Why did you turn off the air conditioner before we left?

c. Jack: But the room will be so hot when we come back later.

d. Jack: That makes sense. I will double-check the lights next time too.

e. Chloe: Because leaving it on while we are out wastes a lot of energy.
