impact is vast and impossible to cover in one article but I will attempt to cover a basic overview. For 200 years we’ve been conquering Nature. Now we’re beating it to death. ~ Tom McMillan Water Pollution Perhaps the most obvious examples of a negative human impact on the environment is water pollution. It’s obvious we need water to survive but few people realize how much we need and just how much is available. Consider these facts from the United Nations Environment Programme: * Of all the

GEOGRAPHICAL ISSUE Introduction The quality of the air we breathe directly affects our general health and well being. The regular monitoring and maintenance of air quality is‚ therefore‚ extremely important for our overall quality of life. A key environmental issue which Australia currently faces is reversing the degradation of our ambient (outside) and indoor air quality. Aside from affecting human health‚ the presence of air pollutants in high levels can also adversely impact upon wildlife and

The water of the UHigh Creek is excellent‚ however some creeks have been polluted and overall have a worse water quality. There are a few different ways a pond or creek can become polluted. One type of pollution caused by humans is Eutrophication‚ which starts when farmers put fertilizers on their crops. The fertilizer can be washed off from the rain and can carry it to a nearby stream or lake. The nitrates and phosphates that are being put in the water fertilize algae and cause its population to

Air pollution in Hong Kong is often so bad that it is impossible to see across Victoria Harbor due to all the haze and smog. The government did endeavor to modify the air quality but‚ sadly‚ it still deteriorates continually. Even worse‚ the Air Pollution Index recently hit a record high‚ which suggests that the air quality in Hong Kong is far lower than the international standard. It all shows that air pollution is just a growing problem and I’m writing to raise several concerns about air pollution
