The Earth was formed about 4,540,000,000 years ago. In the beginning, the Earth’s atmosphere contained very little oxygen (less than 1% oxygen pressure). Early plants started to develop more than 2 billion years ago, probably about 2,700,000,000. Through photosynthesis, plants uptake carbon dioxide into the biosphere as organic matter, and release oxygen as a byproduct. [...]
Global Warming is a dramatically urgent and serious problem. We don’t need to wait for governments to find a solution for this problem: each individual can bring an important help adopting a more responsible lifestyle: starting from little, everyday things. It’s the only reasonable way to save our planet, before it is too late.
The greenhouse effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth’s natural processes. It is the result of heat absorption by certain gases in the atmosphere (called greenhouse gases because they effectively ‘trap’ heat in the lower atmosphere) and [...]
People are doing many things to try to stop global warming. One thing people are doing is carpooling. Carpooling is driving with someone to a place that you are both going to.
