Environmental problem

I am going to have an examination tomorrow and environmental protection is a big topic today.

So I think the question of the composition may be something about environmental problem.

Therefore, I intend to to memorise the article below that I get from the internet.

However, I don't know whether the article is grammartically right. Could anybody check it for me?

Many thanks in advance.

Driving a car or using electricity is not wrong. We just have to be smart about it.Some people use less energy by carpooling. For example, four people can ride together in one car instead of driving four cars to work.

Bike, Bus, and Walk
You can save energy by sometimes taking the bus, riding a bike, or walking



Plant Trees
Planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air.


Recycle
Recycle cans, bottles, plastic bags, and newspapers. When you recycle, you send less trash to the landfill and you help save natural resources, like trees, oil, and elements such as aluminum

.Save Electricity
Whenever we use electricity, we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot.
