MST Flashcards
is the art and science of cultivating the soil, growing crops and raising livestock.
Agriculture
provides most of the world’s food and fabrics.
Agriculture
under this more than 800 million people currently do not get enough food to meet their nutritional needs every day.
food and water
Provides wood for construction and paper products
Agriculture
It includes the preparation of plant and animal products for people to use and their distribution to markets.
Agriculture
The UN currently projects that we will need this percentage of more food by 2050
70%
currently this percentage of extinction threats to mammals and birds are due to agriculture.
80%
Two of the most significant threats to biodiversity.
Habitats
is an absolute basic human necessity, and each person adds to demand threats to this.
Water
The United Nations has calculated that water shortages as a result of climate change could displace hundreds of millions of people by this year
2030
refers to atmospheric conditions that occur locally over short periods of time—from minutes to hours or days.
Weather
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.
Climate
is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates.
Climate change
is 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.
Water quality
are essential for life as we know it, in cultivated farmland, sustainability, human consumption, economic development, and environmental systems.
Water resources
contaminations (specifically in rivers and streams) are mainly due to urbanization, agriculture, and manufacturing discharge.
Surface water
released by agriculture activities include metals, pesticides, pathogens, nutrients, and salts that inlfluence surface water
Pollutants
When this is polluted with toxic chemical compounds through human activities it can become unsuitable for several years.
Ground water
Non-carbon-based materials are referred to as inorganic pollutants.
Inorganic Substances
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.
Global Warming
refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities.
Deforestation
Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.
Deforestation
include natural forest fires or parasite-caused diseases which can result in deforestation. Nevertheless, human activities are among the main causes of global deforestation.
Natural Factors
definition is an area or region’s population growing to such an extent that it becomes unsustainable given the available resources
Overpopulation
If humans were rare or an endangered species, then overpopulation would never become a problem
Overpopulation
is an activity that results in a serious reduction of a species’ population or harm to wildlife.
Fish and other aquatic species
means harvesting species from the wild at rates faster than natural populations can recover.
Overexploitation
are both types of overexploitation.
Overfishing and overhunting
Overhunting
is as real and scary as it truly sounds.
measures the date on which humanity’s cumulative use of resources each given year surpasses the planet’s natural capacity (or biological capital).
Earth Overshoot Day
