Why is climate change an important issue? 3 reasons why? Please hurry!!

Climate Change is a massive product of 21st century humanity, as we as a species pollute more then ever before. There are many ways in which we pollute, however that is not important as your question requests why it is an important issue. The byproducts of internal combustion (Vehicular burning), and factory pollution not only pollutes the atmosphere with extra co2, but also with unnecessary heat. Our planet Earth is based off a delicate balance between man, plant life, animals, and the atmosphere. Ever since the 1750's we have begun polluting more and more. This causes many problems, the co2 makes less oxygen in the atmosphere meaning while plantlife will flourish, Earth's wildlife and mankind will go on the road to extinction. Another byproduct is heat, which can melt the polar ice caps. This will cause heavy damage to manmade infrastructure, and inevitably wipe out 1/5 of earths population (If not evacuated). Finally, Agriculture, while intense co2 might allow agriculture to flourish, the heat will not allow it to cool down to the specific temperature ratio for the crop to successfully provide a bountiful harvest. This is why we have things like "Strawberry Season" which grows a specific type of crop at a specific point in the year.

Hope the above was useful!

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
