Answer:
Explanation:
a. ozone-depleting chemical production and use: Ozone depletion chemicals are Chlorofluorocarbons (CFCs), chlorine,hydrochlorofluorocarbons (HCFCs), carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform. etc. This chlorofurocarbon is responsible most for ozone depleting chemical production and use. This gas is used in the refrigerator,A.c and others. Those chemicals deplete the ozone layer of the atmosphere which absorbed the radiation of ultra violet rays. The ozone depleting gas mainly comes from the factories, car and other human productions. This damage human health ,plants animals health and other. Thus the ozone-depleting chemical production and use by human being make changes to the environment.
b. acid deposition: Deposition of acid on earth can present in either wet or dry form. Emission of polluted substance , mainly sulfur dioxide and nitrogen oxide using in car,factories,huge industries and power plant which are important human creation get out by human activities and mix with the air. Then it comes back on the earth by the form of acid rain and deposit on the earth. This affects environment, plant, animals and human body also. Thus human caused acid deposition or acid rain makes changes on environment.
c. climate change: Climate change also happen by human activities. Emission of gases from industrial factories, car etc which are the human creation increase global warming. Greenhouse effect also occurred by human activities. This global warming mainly caused by different economic system which put a risk on environment. Climate change impacts on agriculture, human health, food chain, biodiversity , rainfall, which cause changes on economic system by low growth of food grain, low production,human creativity etc.
Thus these three make changes on the earth environment. and affects on economic system by human activities.
