Module 6-10

Agriculture

is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets.

Kenneth Boulding

“Anyone who believes in indefinite growth of anything physical on a physically finite planet is either a madman or an economist.”

Weather

refers to atmospheric conditions that occur locally over short periods of time—from minutes to hours or days.

Climate

refers to the long-term (usually at least 30 years) regional or even global average of temperature, humidity, and rainfall patterns over seasons, years, or decades.

Global Warming

is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. This term is not interchangeable with the term "climate change."

Climate Change

is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.

Water quality degradation

happened through the natural processes that influence the surface water and groundwater quality by various sources such as climate changes, natural disasters, geological factors, soil-matrix, and hyporheic exchange.

Anthropogenic Pollutants

are substances caused by human actions, mostly resulting from land-use practices.

Air Pollution

Soil Pollution

Noise Pollution

Water Pollution

Types of Pollution

Surface Water Contaminatons

are mainly due to urbanization, agriculture, and manufacturing discharge. In addition, environmental physical factors can also cause contamination, whereas the temperature of an aquatic environment can fluctuate with heated water discharged from power plants.

Overpopulation

an area or region's population growing to such an extent that it becomes unsustainable given the available resources. These resources can include food, water, physical land, and other natural resources.

Population Momentum

This type of growth is caused by a large number of people of reproductive age, even if fertility rates are lower. This is due to high fertility rates in the past.

Sparsely Populated Areas

Even areas with little ability to sustain life can be overpopulated. For example, a desert can be overpopulated if it doesn't have the resources to support the population.

Overhunting

an activity that results in a serious reduction of a species’ population or harm to wildlife. It is otherwise defined as the relentless chase for wild or game animals to kill or catch them for economic reasons, personal gains or food.

Overpopulation

The increase of human populations across the world has significantly increased, thereby leading to a high number of people encroaching into wild areas that have extensively resulted in poaching and mass hunting.
