Will human beings' selfish acts bring about the Earth's doom?
Yes. At the current speed of carbon dioxide being released into the air, humans' acts will bring about Earth's doom.
Nowadays, more and more cars are coming onto the road. As cars give out carbon dioxide, more of it will be released into the environment. As the factories are also burning lots of fossil fuels, voluminous amounts of carbon dioxide would then be produced, contributing to the carbon dioxide in the atmosphere. Moreover, more trees are still getting chopped down. In some events, the forest would have a fire. This would then produce a large amount of carbon dioxide. Like this, the earth's temperature would start to rise. As the temperature rises, the ice in the north and south pole would start to melt, changing from solid to liquid state. This would then cause the water level in the sea to rise. At this rate, the whole earth would be buried under water in no time. Is it really that important to have your own car and using the fossil fuels to harm the Earth? Sometimes, I ask myself why are humans' so selfish? Why cant human just lead a simple life ?
What we can we do to save the Earth?
We can start conserving water. If possible, someone should invent machines that are able to get rid of the carbon dioxide in the air. More people should start taking public transport bus services as it reduces a lot of carbon dioxide given out compared to the cars. Scientists should find out ways to reduce the damage done to the Earth. Furthermore, we could also use the 3"R"s to keep the earth keep from pollution.
