Our burning of fossil fuels for energy poses several different problems. Describe what is generally considered the biggest problem and the main reason for using alternatives. PLEASE HELP!!

Pollution! Those fossil fuel that are being burned to turns the smoke into the atmosphere that begins to affect the quality of air…in huge industries in China many of the people have to suffer pollution because of the big factories in creating all their manufactured materials. Different alternative they could consider is filtration of the smoke that goes in the air. A filter on the pipe that release the smokes so it brings out clean air instead

Remember, a pH of 7.0 is neutral. Anything above that (7–14) is basic, and anything below that (0–6) is acidic. pH of hand soap is in the range 9-10, but as natural pH of skin is slightly acidic (around pH 5) such soap lefts skin dry and rough, thus more and more soap producers modify their recipes to lower soap pH.milk has a pH of around 6.5 to 6.7, which makes it slightly acidic. Some sources cite milk as being neutral since it is so close to the neutral pH of 7.0. However, milk contains lactic acid, which is a hydrogen donor or proton donor.Saliva has a pH normal range of 6.2-7.6 with 6.7 being the average pH. Resting pH of mouth does not fall below 6.3. In the oral cavity, the pH is maintained near neutrality (6.7-7.3) by saliva.The pH level of 0.25L of chicken soup is 5.80.
