Environment and it causes
- 1. ENVIRONMENT AND ITS HUMAN CAUSES SUBMITTED BY :- ANNU KUMARI CLASS :– M.COM. IST SEMESTER ROLL NO. :– 15 SESSION :- 2018-2020 DEPARTMENT OF APPLIED ECONIMICS AND COMMERCE
- 2. HUMAN IMPACT ON ENVIRONMENT
- 3. HUMAN IMPACT ON ENVIRONMENT MEANS OVER POPULATION POLLUTION Overpopulation has grown into an epidemic since mortality rates have decreased, medicine has improved, and methods of industrial farming were introduced, thus keeping humans alive for much longer and increasing the total population. Pollution is so bad that to date, 2.4 billion people do not have access to clean water sources. Humanity is continuously polluting indispensable resources like air, water, and soil which requires millions of years to replenish.
- 4. HUMAN IMPACT ON ENVIRONMENT MEANS GLOBAL WARMING CLIMATE CHANGE Global warming is arguably the greatest cause of impact to the environment. The largest of causes emanating through CO₂ levels from respiration to more detrimental causes like burning fossil fuels and deforestation. Climate change is closely connected to historical developement of industry and technology. As global temperatures increase, Earth's weather patterns will drastically change.
- 5. HUMAN IMPACT ON ENVIRONMENT MEANS GENETIC MODIFICATION OCEAN ACIDIFICATION GMO's are selected bred crops or crops that have had DNA directly implanted into it in order to give an advantage to the crop, whether that be to sustain colder temperatures, require less water, or yield more product. Ocean acidification is caused when CO₂ dissolves into the ocean bonding with sea water creating carbonic acid.
- 6. HUMAN IMPACT ON ENVIRONMENT MEANS WATER POLLUTION DEFORESTATION Every year over 8 millions tons of garbage dumped into the ocean. Not only is garbage introduced into the oceans, but also the excessive amounts of fertilizer that finds its way into the ocean through rains, floods, winds, or dumped in excess right into the largest producer of oxygen we have. With an exponential expansion in human beings, more food, materials, and shelter are being manufactured at stupendous rates, mostly stemming from forestry. Forests are cleared to make way for new humans, which in turn, makes more humans, you can see the problem.
- 7. HUMAN IMPACT ON ENVIRONMENT MEANS ACID RAIN OZONE DEPLETION When humans burn coal, sulphur dioxide and nitrogen oxides are released into the atmosphere where they rise up and accumulate in the clouds until the clouds become saturated and rain acid, causing havoc on the ground beneath. The ozone layer is renowned for its ability to absorb harmful UV rays that would otherwise be detrimental to the health of all walks of life. Without an ozone layer, walking outside would be unbearable.
