Prompt Describe the connection between human activity and environmental changes that occurred from 1900 to the present.

Explanation:

There are so many environmental changes that have occurred from 1900 to present. This is due to the fact that, human race wants to make everything available for themselves.

The changes include

* Loss of biodiversity

* Depletion of ozone layer resulting to global warming

* Land degradation

* Urbanization

The connection between human activity and environmental changes is very apparent when you look at climate change and how the Earth’s terrain has changed in the past 100 years. People cut down an average of 15 billion trees per year (from an article on time.com), which amounts to about 1,815,000,000,000 trees cut down since 1900. This is as a result of technological advancement by humans, and human activity has affected many other facets of the environment. For example, as a result of the increased use of fossil fuels to power machinery, the increased process of extracting natural resources to the point of near scarcity, and the destroying of environments to satisfy human needs, the environment has been suffering greatly. One prime instance of this environmental damage is climate change, which is when the climate changes as a result of pollutants in the atmosphere. These pollutants are a direct result of the increased human activity in the machinery and technology industries, as the burning of fossil fuels and the operating of machinery release carbon dioxide into the atmosphere, damaging the atmosphere. The use of machinery and fossil fuels really began to pick up steam in the 1900’s. So, as a result of increased human activity in environmental affairs since 1900, the environment has suffered greatly, increasing the global climate, decreasing oxygen levels, and increasing the risk of UV ray damage to living organisms.

I got a 90% on this, enjoy :)

12.4%

Step-by-step explanation:

The results from the random sample counts 124 from a total of 1000 people that wear contact lenses. This means is the percentageof the people in the sample that wear contact lenses.Because it is a random sample, it is suppose to reflect the behavior of the total population. Then we can expect or predict  similar percentage of Americans wearing contact lenses (12.4%).
