🌾 Green Revolution
What is the Green Revolution?
A time around 1950 when humans became better at growing crops using new farming practices.
What is a feedlot or CAFO?
A large facility where many livestock are kept crowded together and fed grain
What is overfishing?
Catching fish faster than they can reproduce, which depletes fish populations
What is deforestation?
Clearing Earth's forests on a large scale
Name ONE sustainable farming practice.
Free-range grazing, organic farming, IPM, hydroponic gardening, vertical farming, community gardens, or aquaponics (accept any one)
Name ONE farming practice introduced during the Green Revolution.
Chemical fertilizers, synthetic pesticides, herbicides, high-yield crops, or increased machinery
What gas do cows release through their burps and farts?
Methane
What is bycatch?
The accidental capture of non-targeted animals during fishing
What is the biggest reason forests are being cut down?
Agriculture (crop farming and livestock grazing)
What does IPM stand for?
Integrated Pest Management
Why did the world need the Green Revolution in 1950?
The human population was growing and we needed more food to feed more people
Why do cows in feedlots produce so much methane?
They are fed grain instead of grass, which their stomachs are not designed to digest
What is aquaculture?
Fish farming — raising fish in controlled environments like ponds or tanks
What is biodiversity?
The variety of all living things and where they live
What is hydroponic gardening or vertical farming?
Growing plants without soil in controlled environments (greenhouses or stacked trays) using less water and land
The Green Revolution helped produce more food, but what was ONE environmental problem it caused?
Soil erosion, water pollution, air pollution, habitat loss, or biodiversity loss
Is industrial farming better or worse for the environment than sustainable farming? Why?
Worse (it causes more pollution and uses more chemicals)
What is aquaponics?
A system where fish and plants grow together — fish waste fertilizes plants, and plants purify water for fish
How does deforestation affect biodiversity?
It destroys habitat and threatens species with extinction
What is a community garden?
A shared piece of land where a group of people grow fruits and vegetables together
Name TWO farming practices from the Green Revolution.
chemical fertilizers, synthetic pesticides/herbicides, high-yield crops, increased machinery
Give ONE reason why industrial farming is used even though it causes environmental problems.
It's economically efficient, keeps food prices low, or allows us to meet high meat demand
Is aquaculture a good solution to overfishing? Give ONE reason why or why not.
Yes — reduces pressure on wild fish, provides protein efficiently. OR No — can contaminate water, escaped fish compete with wild populations (accept either with reasoning)
Why are tropical rainforests important to protect for biodiversity?
They are home to much of the world's biodiversity; 70% of Earth's land animals and plants live in forests
Is sustainable farming better for the environment? Give ONE reason why.
Yes — uses no synthetic chemicals, uses less water, is more humane to animals, doesn't deplete soil (accept any reason)
