GM Crops
GM crops are preferred for their higher __________.
What are yields?
The layer providing the most nutrients for plants is _________.
what is the topsoil?
This process moves crops or alternates crops to preserve soil health and fertility
What is crop rotation?
These are major causes of the Dust Bowl issue in the 1930s.
what is overgrazing by domesticated cattle (no more buffalo), removal of native grasses for farming, loosened soil from farming and drought?
this is a product of livestock that can help enrich soil and help plants grow.
what is manure?
this is the term we use when city expansion becomes uncontrolled.
what is urban sprawl?
some pollution types have a single, identifiable source.
what is point-source pollution?
These are a few of the main concerns opposers of genetic modification of plants for human consumption.
What are allergic reactions and dietary restrictions possibly being an issue because GM foods don't REQUIRE a label? (other answers may be accepted)
This is typically the primary case of degradation on farmland.
What is erosion?
This is the practice of using a predator to eat a pest on a farm.
What is biological pest control?
Fertilizer runoff, typically from nonpoint-source pollution, can contribute to this issue (like it does in the Gulf of Mexico).
What is eutrophication?
these are other products provided by livestock to humans.
what is meat, leather, milk, cheese, manure, gelatin, bone meal.
data-based tools to assist in land use planning along with maps
what is GIS (geographic information system)?
toxins can accumulate through the food web through biomagnification because each trophic level only absorbs 10% of the energy from the previous level requiring the animal to _______________.
what is eat more to be satiated or consume more food?
GM crops pose an ecological concern because they may outcompete native crops and non-GM crops causing this...
what is loss of biodiversity?
This process, learned when we covered alternative farming methods, helped to improve soil quality by adding organic matter (food waste or manure).
What is composting?
Composting revives the soil's ________.
what are nutrients?
Overgrazing has these 2 major initial effects on land.
What is loss of vegetation and increased erosion?
these are several ecological services grasslands provide
urban surfaces can raise local temperatures and we call it this
what is a heat island or heat island effect?
excessive pesticide use can cause hazards such as
what is contaminate water sources?
GM crops can help reduce pesticide use and possibly water contamination by run off due to this.
Overgrazing may impact soil and cause this.
What is erosion?
desertification is also ok.
This harmful effect is usually the result of irrigation when groundwater has a certain mineral. The crops grown in the soil that has been negatively affected by crop yields being lower.
what is salination? (or salinization)
THIS practice helps control erosion and will help absorb and cycle carbon in areas where trees had previously been removed (deforestation).
what is reforestation?
these are the negative effects of overgrazing
what is erosion and degradation of soil
name at least 5 things we consider infrastructure
what are road systems, highways, bridges, water treatment systems and pipes, electricity generation and distribution, landfills and other utilities; school systems, markets, technology, manufacturing, shipping systems, trains and subways?
what is a recharge zone or what is natural water filtration?
When creating GM crops in the lab __________ is modified in the process.
what is genetic material?
Fertile land can become arid in this process (and no longer be able to support plant life).
This way of using plants can help both erosion and evaporation around crops.
This is the process where toxins accumulate through the food chain.
what is biomagnification?
what is smaller herds, replanting native grasses, giving areas a break from livestock grazing to allow the area to recover? (you must have named at least 2 of these or another qualifying answer --per Ms. Hendricks)
proper land management would aim to do this.
what is limiting urban sprawl (growth of urban areas) and preserve enough green space (rural area) to support the population?
what is balancing urban and rural land use to sustainably support a population?
thermal pollution disrupts aquatic systems when this gas is affected by temperature change.
what is reducing dissolved oxygen levels in the water and making water uninhabitable?
