Is the sun renewable source?

Today,in Environmental class we have learned about renewable source and non-renewable source. I had a lot of questions so I decided to read my text book.While I was reading chapter 1 in Environmental Science text book, I was wondering why is the sun renewable source. I had been watching so many news or articles claiming that the sun is dying quite rapidly from elementary school and until now. I was not sure if sun is renewable source or nonrenewable source, so here I am writing 1 reason why it is considered as renewable source and 1 counter reason why it can be also called as nonrenewable source.

First of all, students should know the definition of renewable source. According to the dictionary, renewable source means natural resource which replenishes to overcome resource depletion caused by usage and consumption, either through biological reproduction or other naturally recurring processes in a finite amount of time in a human time scale. The sun is resource that human can use for long and long time. This is due to the fact that sun is sustainable until we, as our generation becomes non living thing. Therefore, "Is the sun renewable source or nonrenewable source?" is question that our future generation to consider, while our generation can use the solar energy without any worries.

On the other hand, the Sun can also be nonrenewable source because it is not the source that it replenish itself which goes against the definition of renewable source. According to the research, it claims that the sun will eventually extinct. This is due to the fact that the sun uses hydrogen to combine into helium which then can make heat; but, the sun has used up about approximately half of its hydrogen fuel. If the sun is out of hydrogen fuel, it will eventually extinct. We will never know about the future.

In my opinion, I think that the Sun can be renewable source and nonrenewable source. I personally think that Scientist should add more detail on definition of renewable source, saying that renewable source is source that people can rely on without any worries on their generation.

The planet's temperature is rising: Global Warming

Today we learnt about pollution in our environmental class and I learnt that weather is relevant with pollution. I feel like weather is getting worse every single year. During summer, I feel like it's getting hotter and during winter, I feel like it's getting shorter. According to the research, global warming is the main cause of this. Then why does it occur? How can people stop it? What will happen if this keep goes on? I had a lot of questions that popped out in my brain and I decided to write these questions' answers on my blog. I read an article which helps my answer.

First of all, according to an article, global warming causes mainly by carbon dioxide. This is due to the fact that carbon dioxide consume reflected heat from the surface of Earth, which means that the heat from Earth will not be able to move on to the space because carbon dioxide is consuming all the heat, that will heat the Earth. What can people do to stop making carbon dioxide?  According to an article, carbon dioxide is made when we burn fossil fuels such as oil, coal, and natural gas that is basically for electricity, vehicles, heat and etc.. Basically, it will be quite hard for people to stop global warming.

On the other hand, if the global warming keep continues, people will be in trouble by increase of sea level, extreme storms rise in some areas, more droughts and etc... which will ultimately cause extinction of living things. In order to stop that, people should stop making carbon dioxide. Therefore, scientist nowadays are making substitution that makes people to stop burning fossil fuels. I strongly believe that people should care more about how serious is global warming.
