Land Pollution Flashcards
It also refers to an activity that lessens the quality and/or productivity of the land as an ideal place for agriculture, forestation, construction, etc.
LAND POLLUTION
It is often caused by human activities and the misuse of land resources which could lead to undesirable changes in land, like soil erosion.
LAND POLLUTION
The deterioration of Earth’s land features and soil, directly or indirectly.
LAND POLLUTION
It is carried out to create drylands is one of the major concerns.
Deforestation and Soil Erosion
alteration or modification of original properties of land to make it use-worthy for a specific purpose, is another major cause.
Land conversion
Land that is once converted into dry or barren land can never be made fertile again.
Deforestation and Soil Erosion
in search of more land, potent land is hunted, and its indigenous state is compromised.
Deforestation and Soil Erosion
Also, there is a constant waste of land. Unused available land over the years turns barren; this land then cannot be used.
Deforestation and Soil Erosion
In agricultural activities, overuse of these chemicals, they result in _____
contamination and poisoning of soil.
Farmers often use toxic fertilizers and pesticides to get rid of insects, fungi, and bacteria from their crops.
Agricultural Activities
Items that cannot be recycled become a part of landfills that hamper the beauty of the city and cause land pollution.
Overcrowded Landfills
Garbage like aluminum, plastic, paper, cloth, wood, is collected and sent to the local recycling unit.
Overcrowded Landfills
Several land spaces are created beneath the surface.
Mining Activities
Research and development paved the way for modern fertilizers and chemicals that were highly toxic and led to soil contamination.
Industrialization
Due to an increased demand for food, shelter, and house, more goods are produced. This resulted in the creation of more waste that needs to be disposed of.
Industrialization
Marks a significant change to the landscape that can cause land pollution in a variety of subtle and not-so-subtle ways.
Urbanization
Many of us may not classify human settlements as “land pollution
Urbanization
Due to urbanization, a large number of construction activities are taking place, which has resulted in huge waste articles like wood, metal, bricks, and plastic that can be seen by naked eyes outside any building or office which is under construction.
Construction Activities
The leftover radioactive material contains harmful and toxic chemicals that can affect human health. They are dumped beneath the earth to avoid any casualty.
Nuclear Waste
The leftover material is then sent to the landfill site, which ends up polluting the environment.
Sewage Treatment
A large amount of solid waste is leftover once the sewage has been treated.
Sewage Treatment
People just throw their garbage on the ground without caring about the adverse effects on the environment.
Littering
Another form of land pollution, where the upper layer of soil or the topsoil’s composition is damaged or altered. This is caused by the overuse of chemical fertilizers, soil erosion triggered by running water and other pest control measures, leading to loss of fertile land for agriculture, forest cover, fodder patches for grazing, etc.
Soil Pollution
When harmful substances from industrial processes like chemicals are improperly disposed on the land or in illegal landfills or storages, the chemicals and other substances could end up in the groundwater system.
Groundwater Poisoning
Highly affected by land pollution. Nearly _____ of the world’s population does not have access to safe drinking water, and each year water-based diseases cause up to ______ deaths.
Drinking Water Problem
When deforestation is committed, the tree cover is compromised. This leads to a steep imbalance in the rain cycle.
Environmental Impact
The effects of land pollution are very hazardous and can lead to the loss of ecosystems. When land is polluted, it directly or indirectly affects the climate pattern.
Change in Climate Patterns
The land, when contaminated with toxic chemicals and pesticides, lead to potentially fatal problems like skin cancer and the human respiratory ailments in particular.
Effect on Human Health
The city loses its attraction as a tourist destination as landfills do not look good when you move around the city. It leads to a loss of revenue for the state government.
Distraction for Tourists
Landfills across the city keep on growing due to an increase in waste and are later burned, which leads to air pollution. They become home for rodents, mice,etc., which in turn transmit diseases.
Causes Air Pollution
The constant human activity on land is leaving it polluted, forcing these species to move further away and adapt to new regions or die trying to adjust. Several species are also pushed to the verge extinction, due to no homeland.
Effect on Wildlife
They face a serious threat with regards to the loss of habitat and natural environment.
Effect on Wildlife
The dry conditions created by pollutants in the soil create the perfect environment for wildfires and increases the probability of wildfires dramatically.
Wildfires
Chemicals that are frequently used on agricultural farms, such as nitrogen, end up benefitting the crops only in a small proportion. The rest ends up in water populated by fish, algae, and other lifeforms.
Water Nutrient Enrichment
produced by mines, farms
or agriculture, and industries that supply
people with goods and services
Industrial Waste
all the wastes arising from
human and animal activities that are normally
solid and are discarded as useless or
unwanted.
Solid wastes
Wastes that are generated from living households,
generally contain non-hazardous solid wastes;
kitchen waste, found usually at home.
Residential
often called garbage
or trash, which consists of the combined solid
waste produced by homes, institutions, small
businesses, and workplaces other than
factories.
Municipal Solid Waste
Wastes generated from business establishments:
food establishments, shops, etc., that generate
generally non-hazardous waste such as paper,
cardboard, wood, metals and plastic.
Commercial
These are solid wastes due to agricultural
activities: food residues, animal dung, crop
residues, etc.
Agricultural
Generated from public and government
institutions: offices, religious institutes, schools,
universities, etc.; generally, not hazardous.
Institutional Solid Waste
It is from various types of industrial processes. The
nature of the waste depends on the type of
industry and kind of raw material involved. There
may be toxic and hazardous wastes that have
adverse effects to the environment.
Industrial Waste
Discarded, unwanted solid wastes from hospitals.
It consists of both non-hazardous and hazardous
waste.
Hospital Solid Waste
Open Dumping: Considerations in selection and locating sites for open
dumping (4)
• Sources of water supply and distance from it
• Direction of wind
• Distance from nearest residents, nearby farm areas
and main land.
• Distance that flies can travel from disposal site to
living quarters as well as the distance that the
rodents can travel from disposal areas and living
quarters
It differs in ordinary dumping in that the material
are placed in a trench or other prepared area,
adequately compacted, and covered with earth
at the end of the working day.
Controlled Tipping/Burial Sanitary Landfill System
Steps in Controlled Tipping (5)
• Choosing a suitable site, usually wasteland, to be
reclaimed within reasonable distance from habitation.
• Transporting the generated wastes to the site by
appropriately designed vehicles.
• Laying the wastes in appropriate heap to a
predetermined height
• Compacting the layer mechanically.
• Covering the compacted layer with a thin layer of earth
22 cm depth at the end of each work day. The same
steps are repeated for each work period
a process of burning the combustible
components of garbage at temperatures high
enough to destroy contaminants. It red a process of burning the combustible
components of garbage at temperatures high
enough to destroy contaminants. It reduces volume
of waste by 20-30% of original volume.
Incineration
Usually have high economic
value and are particularly useful to mankind. Examples of these products are metals like
copper, gold, and zinc as well as gems like
rubies, sapphires, and diamonds.
Mining products
Is the extraction of valuable minerals or
geological materials from the surface or under
the surface of the Earth.
Mining
Some of the environmental impacts of mining
include:
•Soil erosion
•Sinkholes
•Loss of biodiversity
•Contamination of soil, groundwater, and
surface water
•Increase in carbon emissions
It can drastically alter the conditions
in a particular area in just a short
period of time, especially if the
sustainability measures are not
observed.
Environmental Impacts
It is worth noting that the law recognizes the rights of
indigenous people (IP) to their ancestral domains,
mandating royalty payments to the IP communities
should be given for the minerals in their areas were to
be utilized.
Republic Act No. 7942
The Philippines, being the fifth most mineral-rich
countries in the world have a huge potential to be
developed if our mineral resources are conserved and
utilized properly.
Republic Act No. 7942
This
law aims to promote proper exploration,
development, utilization, and conservation of our
mineral resources through the combined efforts of the
government and the private sector.
Republic Act No. 7942
Also known as the Philippine Mining Act of 1995
Republic Act No. 7942
This act is also known as the People’s Small-scale Mining
Act of 1991.
Republic Act No. 7076
Its main objective is to promote small-scale mining
activities and give access and more opportunities for
small-scale miners to partake in the land’s natural
resources.
