Nowadays, the earth becomes warm and warm due to emitting of greenhouse gases, pollution in air, water and others and deforestation. That's because we use energy without thinking that leads to unsustainable development. The effects will impact not only on our generation but also on next generations causing them not able to continue living anymore.
Since the past few centuries, people have been inviting new things to comfort our everyday lives. E.g. producing new models of cars. Rich people are competing each others and they will buy every new car. On another aspect, they are using more oil and causing air pollution and it will lead to increasing scarcity of oil. Next up, have u noticed that we use paper everyday in schools, homes and works? Paper is made from trees and I've read that " one sheet of paper is made from 10 trees". I don't know that is a true fact or not. Next, population is growing all over the world and to cover all people's starvation, agriculture has to be risen up and forest needs to be wiped out in order to get space. Again, it causes deforestation. Less trees means less carbon dioxide, one of the greenhouse gases, is taken and the rest is released to the atmosphere.
I don't want to say " don't invite new things" but it is necessary to use renewable energy like wind energy, solar energy, water and other alternatives fuel that will help us with scarcity of resources. Let's make our next generations able to inherit the beautiful world with full of resources from us.
