Revise what have you already learned about There is and There are!
To talk about how transport affects the environment, you need to know the right words. Read the example and learn some new vocabulary:
There are many options for transport, but some are better for the environment than others. Cars and buses use fuel and produce gas, which creates pollution. This can have a bad effect on the air and on nature. Walking and riding a bike are very eco-friendly and nature-friendly. They do not produce gas and help reduce pollution. Trains are also a good option because they use less fuel and have a smaller effect on the environment. If people choose eco-friendly transport, we can reduce pollution and protect the environment. Every small choice makes a difference.
