How to Save The Earth.

The human race cannot claim to have created (did not create) nature, yet, sadly, we feel we have the right to use it and abuse it in whatever way we see fit. (manner we like.) That said, it is not all gloom and doom. There seems, at last, to be a worldwide recognition of the damage we are doing to our planet and concerted efforts are being made to improve our environment. So,what can be done? (Currently, we are regret what we have done and try to make the situation better.) Well, firstly, although we cannot repair the damage done to the ozone layer, (glue the ozone back together,) we can at least reduce greenhouse gases by planting more trees. The benefits to be gained (of trees) would include reducing (your) air-conditioning costs by providing shade, reducing the incidence of  (pulling) carbon dioxide in (out of) our environment and, thus, creating oxygen. Secondly, we should walk more and drive less. For instance, walking or cycling (,) are both considered to be (are) good for our (your) health and the environment. Every time (Everytime) you avoid taking the car, (using cars), you are contributing to lessening (the) air pollution. Last, but not least, we can (Third,) save energy (,) by turning off electrical devices, helping to protect the environment by switching them off completely when not in use. (using them.) By working together, little by little, we can save our planet!

Good work and another intersting topic, with lots of good ideas knitted into your article. I felt the article would benefit from a stronger opening, prior to introducing the measures we should take, so have suggested adding a few extra sentences.

The human race did not create nature, yet we feel we have the right to use it in whatever manner we like. Currently, we are regretful of what we have done and are trying to make the situation better. First, although we cannot glue the ozone back together, we can reduce greenhouse gases by planting more trees.

For instance, walking or cycling, both are good for your health and the environment. Everytime you avoid using cars, you are contributing to lessening the air pollution. Third, save energy, turn off electrical devices, help to protect the environment by switching them off completely when not using them. Together, we can save our planet!
