Natural resources are used to develop housing as building houses require materials such as concrete and steel. Concrete is used to build as it is strong and durable. Steel is also used as it can withstand many elements. This resource is used to build formal housing as it is considered a high-quality building material.

Some human activities that happen due to housing development in cities are deforestation, habitat loss, and the pollution of freshwater rivers. These human activities pollute the land as they destroy the environment and cause animals to lose their homes. These activities also pollute rivers, causing fish and plants to die due to the lack of clean water.

# data[].attributes.body
Some human activities that cause water pollution are the companies that dump their waste into the surrounding rivers. Tanneries produce a lot of toxic waste and if not properly disposed of, the waste can cause the water to be contaminated. This causes the water to be unclean and can harm the animals and plants living around there as well as the people who use the river for water as well as their livelihood.

Expansion of housing developments in cities can increase land pollution if proper environmental safeguards and waste management practices are not implemented. Soil contamination is caused by improper storage, handling and disposal of chemicals used in housing development. These chemicals can include paints, solvents, and pesticides which would impact both humans and the environment when soil and groundwater is contaminated.

When it rains, surface runoff transport contaminants into waterways. Factories dumping of untreated waste discharge from factories into water bodies and the polluted water ends up into waterways drains and river systems which will destroy the aquatic waterways , impact human lives and will limit the amount of of clean water available . The polluteted water may also percolate the ground and reach the groundwater which will also impact the amount of freshwateer.

Natural resources are employed in the development of homes since steel and concrete are needed to build a dwelling. Because it is robust and long-lasting, concrete is utilized in construction. Due of its resistance to various elements, steel is also utilized. Since it is regarded as a premium building material, this resource is utilized to construct formal homes.

If appropriate waste management techniques and environmental safeguards are not put in place, the expansion of housing complexes in cities may lead to an increase in land contamination. Chemicals utilized in house development are improperly handled, stored, and disposed of, which results in soil contamination. When soil and groundwater are contaminated, these chemicals—which can include paints, solvents, and pesticides—have an adverse effect on both people and the environment.

Surface runoff introduces pollutants into streams during rainy seasons. Untreated sewage discharged by factories into water bodies ends up in river systems, sewers, and waterways, destroying aquatic environments, endangering human health, and reducing the amount of clean water accessible. The quantity of freshwater may be impacted if the contaminated water seeps through the ground and reaches the groundwater.

Wood is a primary natural resource used in construction. Wood-based materials like plywood are common in the construction of walls and roofs. Natural stones, such as granite or limestone, are used for building foundations. It is also used as a durable material for decorative purposes in the construction of walls and roofs.

Improper disposal of construction waste in landfills can lead to soil contamination. Harmful substances from waste may leach into the soil, posing a threat to groundwater quality.

Clearing land for housing development often involves deforestation and removal of vegetation. Loss of vegetation leads to soil erosion, reducing the soil's ability to retain nutrients. The removal of trees also diminishes the natural filtration of pollutants.

Paved surfaces, such as roads, sidewalks, and parking lots, prevent natural water infiltration, leading to increased surface runoff. Runoff carries pollutants like oil, heavy metals, and chemicals from urban surfaces into storm drains and eventually into rivers and streams, contaminating water.

Industries in urban areas often release wastewater containing pollutants into water bodies. Industrial discharges may contain heavy metals, toxins, and chemicals that can harm aquatic ecosystems and compromise water quality.

One example of how natural resources are being used is that many natural habitats are destroyed as the land being occupied by the forest is used to build housing. Another reason is that as the population is growing, the amount and demand of natural resources are on an increase. The recources used like wood are used to build the housing and furnitures,oils and fuels are used for cooking.

The humans living in theses places can pollute these places by littering, harming the animals and the plant in that area. When building houses, there can be impact from mining and other forms of industry when building houses and when the population increases,there will be lesser space for proper garbage disposal leading to land pollution

In a city near a water body, there could be surface run off from the streets carries oil,rubber,heavy metals, and other contaminants from vehicles. The untreated sewage waters can also pollute the water bodies as it is low in dissolved oxygen and high in pollutants which can harm the animals and plants in the water bodies. The water can also be contaminated my sources such like garbage dumps, toxic waste,chemical storage and use areas like near industrial sites.

With more people residing in a concentrated area, there's often an increase in household waste generation. Improper waste management practices, such as illegal dumping or inadequate waste disposal facilities, can result in land pollution.

# data[].attributes.body
One human activity in urban area can be the dumping of untreated waste discharged from factories into water bodies. Industrial facilities in urban areas often release pollutants such as heavy metals, chemicals, and toxins into nearby water bodies through improper disposal practices or accidental spills.

An urban city, surface run-off from the streets carries oil, rubber, heavy metals and other contaminants from vehicles. Groundwater and surface water can be contaminated from many sources such as garbage dumps, toxic waste, chemical storage and use areas, leaking fuel storage tanks and intentional dumping of hazardous substances.

# data[].attributes.body
Resources used in the development of housing are extracted from the environment, from either forest resources or from mining. Wood is extracted from the forest which is usually used to make the furniture in our homes. Steel that reinforces our homes is acquired through mining.

# data[].attributes.body
As more houses are being built, there will be fewer land left to build landfills for our waste materials. Humans will then dispose their waste materials inappropriately, like for example on the streets, which will eventually lead to land pollution as it piles up. This will then cause soil contamination and many harmful effects on plants, animals and humans.

# data[].attributes.body
Water sources can be polluted when surface run-off from the streets which carries many contaminants enter the water. This will result the water to be high in pollutants and low in dissolved oxygen, which may be harmful to humans when consumed as it may still contain harmful substances despite being treated. Water can also be polluted when toxic waste, garbage dumps and leaking fuel storage is released into the water.

Natural resources are essential in the development of housing, specifically steel and wood. Wood is a common material when it comes to construction, and is also considered a renewable resource. Steel is known for being durable and strong, helping to strengthen the structure of the house, making the house able to withstand elements. Concrete is also used to help make the structure of the houses.
