why the sun have umlimited power

the energy of sun is due to hydrogen atom reaction. the sun is like hydrogen bobm. what we receive is very less in comparation to what is emerged out of thoes chemical reactions. further our atmospheric layer protects us from uv light and so we are safe.

since this layer is reducing due to pollution, we afe facing global warming and it will keep increasing if no proper measures is taken.

Nuclear fusion, the same as one massive, continuous hydrogen bomb. The sun is so massive, that matter compresses and fuses in a fusion reaction. That's the reason for the heat and light.

i have saw a movie talk about the sun going die and the earth absolute iced,no any choice,human ride ship to bomb her and finally success,it seems the sun was consuming by self too sharp,human maybe should do think a lot about the energy which will be dead someday,the energy die and we all will die .

for me,i love the sun in case i have any outdoor activity like playing football,but indoor i can not bear the spicy hotting as i living in south too,the weather is really not befit people .

but recently 2 years,i feel it's got cooler than before,usually should be much hotter due to the greenhouse effect but i really feel it being cooler,maybe there in something rung about the greenhouse effect theory? maybe not hotter just cooler if the CO2 complete flood whole the world?
