Artknit Thornhill Articles: Subtopics on the Influence Of Settlements.

Air pollution:

Makes things dirty.
Pollutant-something things dirty.
In Europe, 90% of city dwellers breathe in polluted air.
As urban pollution increase, they produce more pollution.
When the place has more people, there will be more pollution.
Large cities produce more pollutants, overall than rural areas or neighbourhoods.
Sometimes, you will get less pollution in a city, province, or a country.

Water and soil pollution:

Wastewater needs to be treated, so pollutants are removed before it is returned to any waterways.
Solid waste or garbage also needs to be destroyed in a way that does not harm waterways or the land.
About 80% of sewage around the world is untreated, and flushed into waterways.
As more people migrate into cities with poor wastewater treatment, the problem gets worse.

Many waste materials, especially electronic waste such as computers and televisions, it contains poison pollution.
As the waste breaks down, pollutants can be released into the soil, and pass into waterways.

Light pollution:

Deforestation:

Forests near cities are often cut down, to make new factories and housing.
People may begin to protect their forests, instead of cutting down firewood.
Forests can cut down, and provide this land.
In South America, 70% of amazon forests have been cut down to provide land for grazing.

Loss Of Arable Land:

As the population increases, there is a greater stress on the soil.
As the soil becomes over farmed, it loses nutrients.
The soil dries out, and blows away.
Increasing desertification means that people must migrate to find new land for farming.
If they can’t find arable land, farmers may move to urban areas to find other work.
Nouakchott, Mauritania, is slowly being covered by desert sand.
As the land outside the city are being desertified, fewer people can survive there.
To fight against arable land, some cities and communities are trying to increase local food production by turning open spaces, including: backyards, parks, and evan rooftops.

Loss Of Habitat:

As cities grow, they can create gaps and barriers between one area of wildlife habitat and another.
When the habitat was destroyed, animals are forced to move.
The result is an increased number of species, becoming extinct (Animals have died).
Animals and plants that cannot adapt, are reduced in number or die
It is one of the threats.
Loss of biodiversity reduces the ability of all living things to survive.
Urban planners in many cities have created parks to provide habitat for wildlife and a place where people can connect with the natural world.

Less Land For Growing Food:

Increased Food Production:

Farmers are adding more nutrients to the soil.
They use water to supply land so, crops and plants will grow.
The increase in food production means the “lack of food” may not be a global problem.
Already in some areas, such as sub-Saharan Africa, food production is not keeping up with population growth.
People are going hungry because they cannot grow enough money to buy food.

Changing Land Use:

Overcrowding:

When people are close together, they could have many benefits.
People can share resources to solutions and problems.
It can create pollution and costs money.
It wastes people's time.
Some cities did not have much of good housing that means, they are becoming overcrowded.
The solution is to build running tracks, veggie gardens, and school playgrounds on city roofs.
And also, they have spread diseases to each other.

Lack of services:

Some cities also struggle to meet their growing population needs to clean water, medical care, and also schools.
They can afford to provide these services to all of their residents.
Some areas have better services than others, depending on the ability.
Some people don't get any medical care when they are sick.
As urban populations grow, poverty in cities is growing faster than in rural areas.

Change in rural areas:

In 2013, rural populations have decreased for the first time in the USA.
When people move away, businesses closed, and they have fewer jobs.
Most of the people who leave are young males, so the countryside or rural areas are made up mostly young females.
Fewer people work on farms.
Using modern technology helps rural farms.
60% of cell phones are used in farms in developing countries.

Land use conflict:

Increase Global Migration:

Sprawling cities:

Compact Cities:

More Settlements Along Costs:

Environmental damage:
