a: As the sea level rises,
the forest near the coast
becomes salty and dry.

Pair work
Describe one of the pictures about global warming.
Then talk about how animals or plants could be affected.
What can you see in picture d?
I see a wildfire in the forest. The trees are on fire. The smoke is covering the sky, and it’s hard to see clearly. The animals and plants in the forest are in trouble because of this fire. Global warming is making the Earth hotter.

Then talk about how animals or plants could be affected.
What can you see in picture a?
I see a desolate landscape with dead trees and a barren ground. The area is experiencing extreme heat or drought conditions, both of which are consequences of climate change. The lack of water and nutrients can lead to the death of vegetation, which in turn affects the food chain.

Then talk about how animals or plants could be affected.
What can you see in picture b?
I see a group of fish swimming in the ocean under sunlight. Global warming can lead to rising sea temperatures, which can affect marine life. Changes in ocean currents and temperature can disrupt migration patterns of animals like these fish, affecting their ability to find food and navigate their habitat.

What can you see in picture c?
I see a snowy landscape with a tree branch covered in snow and a lovely white rabbit. If there is no snow, the white rabbit would be easily spotted by its predators, which may cause the extinction of this species.

Then talk about how animals or plants could be affected.
What can you see in picture e?
I see a close-up of a bee on a red flower. It is engaged in the act of pollination by collecting nectar from the flower's petals. However, its tongue is too short to perform this action. The bee would die out because they could not get enough honey for food. What’s more, these kinds of flowers would also be rare because they won’t have helpers to spread their genetic material to other flowers.
Homework
Look for some information about global warming in China.
Think about some good ways to stop global warming for the whole Earth.
