The Impact of Man on the Environment Man has had many far-reaching effects on the environment over the years. Global warming, pollution and the damage to the ozone layer are a few of the major things that can be heard about in the news. Man has damaged the earth gradually over the years and this damage is next to impossible to be reversed, we are now trying to stop more damage being caused to the environment. For example, hedgerows have been destroyed but now people have realised what effects this has on the environment, the government are paying farmers to replant them instead of just fencing. Not all of man's effects on the environment are harmful some are beneficial. Conservation work is going on across the country and this is helping to preserve the wildlife and countryside that we have left. The expanding human population has placed a huge demand on the food production of the country. The resources are limited but the population is increasing quite rapidly so the problems are growing. The demand for food means that crops need to be perfect so the use of fertilisers and herbicides is increasing too. Phosphates are products formed by the replacement of some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary, or tertiary phosphate. Also known as trisodium phosphate, tertiary sodium phosphate is used as a detergent and water softener. Primary and secondary phosphates contain hydrogen and are acid salts. Phosphates are important to metabolism in both plants and animals. Primary calcium phosphate, Ca(H2PO4)2, i... ... middle of paper ... ... becoming more popular with the consumer, the demand for organic produce is increasing. Organic food tends to be more expensive as the entire crop isn't perfect but it is environmentally friendly. Man's effects on the environment are many but the effects are being slowed down and where possible reversed. The consequences of many years of abuse to the earth are being realised and people are trying to do something about it. Tillage operations that prepare the soil for planting and control weeds expose bare soil to possible erosion by wind and water. Global warming is being reduced as much as possible by the reduction of toxic emissions and wastewater is being recycled instead of pumped into rivers and seas. Man is trying to reverse and slow down the effects on the environment although some things cannot be reversed.

...crimination against people all over the globe. This misinterpretation and glorification of violence has been one of the major issues as to why inequality still exist.
Unfortunately, while all of these questions are flowing through the ears of the government, other problems are discombobulating the current situation. The recent gun control controversies, rambunctious political parties, the flawed education system, and the misleading media are among the intricate quandaries the United States needs to fix before the first world nation turns into rubble.
· Problems: Employment discrimination, arrests, political conservatism, economic entrenchment, and lack of attention to sexism and racism.
There is no hesitation when it comes to whether humans impact the global environment. However, it is questioned in whether human’s ecological footprint is either negatively or positively impacting. In clear perspective, humans share from both sides and their ecological footprint is noted towards whether it will benefit or harm the environment around them. Topics such as overpopulation, pollution, biomagnification, and deforestation are all human impacted and can harm the environment, but some include benefits into helping the world around us with solutions to their problems.
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
The land now known as America has changed dramatically since the area was taken from the Native Americans. While the Native Americans respected the land and natural resources, the eventual take over from the Americans brought devastating impact to the environment. Rapid population increases, as well as the Industrial Revolution brought forth many negative impacts to the land, air, and ecosystem. The rise of the environmental movement that occurred during the 1960s and 1970s represented a significant shift in thinking in regards to protecting our environment. The impact of the environmental movement has positively impacted our contemporary culture.
I believe overconsumption of resources is the most significant impact that human population size and growth have on the environment. As population size gets bigger, people's need of food, water and services also increases. Forests are being destroyed because of human's need of wood, different kinds of animals are getting killed because human's need of goods and food and fossil fuels are being used because of human's need for electricity and transportation. As a result, many habitats and species are lost, which impacts ecosystem a lot.
Human Impact on the Environment Introduction = == == == ==
Humans rely on nutrients as a source to survive. With crops being a vital part of society, both economically and the importance of the well being of humans, changing the way crops are grown is a concern. It is no surprise farmers are using annual seeds, all while turning a blind eye to an issue bigger than the success of their yearly crop. As farmers continue to practice conventional farming, these conventions are being passed down generation to generation. Hence the problem society is a part of.
Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre.

Long time ago, before the Second Agricultural Revolution, people produced food only enough to feed themselves and their family members. After a series of agricultural revolutions, mankind earned the ability to produce massive amount of food due to the advancement of technology and science. However, this advancement brought the Industrial Revolution. As a result of the Industrial Revolution, the amount of workers that are working in the agricultural field decreased significantly. Due to the advancement of technology, we need less people to produce food, and more people in factories. The decrease of the agricultural worker was not really a problem because they could produce more food with less people due to machines. Therefore, nowadays, not
