Select the reasons why it is necessary to rethink the way we practice agriculture.
Currently agriculture contributes significantly to global warming
Current agricultural practices can produce more than enough food to feed the projected human population of 11 billion in 2050
Currently agriculture protects natural habitats
Currently agriculture is causing aquatic and terrestrial habitat destruction
It currently contributes significantly to water pollution
Which of the following is an undesirable impact of modern agriculture?
Increased mechanization
Increased food production
Erosion
Effective pest control
Reduced manual labour
Since agriculture contributes significantly to environmental degradation and climate change, agricultural practices need to be revisited. What are some requirements of agriculture in the future: (select all that apply).
Smaller areas of land used for farming
Increased food production
Monoculture farm expansion
Reduced livestock farming
Increased agrochemical use
The image was taken in the amazon rainforest of South America. The land is cleared for agricultural expansion. Which of the following are negative side effects of agricultural expansion?
Deforestation
Habitat destruction
Increased food production
Biodiversity loss
Source of income for the local population
Aquatic dead zones can be caused by
fertilizer in runoff
growing cover crops
agroforestry
conservation tillage
Which of the following are the benefits of precision indoor, vertical and greenhouse farming?
Water conservation
Increased food production on less land
Increased air pollution
Reduced transportation distance and time
Increased water pollution
David Attenborough taught us that carnivores require extensive areas of land each and so with the human population growing far beyond what the environment would normally sustain, humans need to change from being meat eaters. We need to source our animal protein from the water. However, fish farming, just like farming on land, needs to be sustainable. What are some of the potential impacts of aquaculture?
Decreased water oxygen content
Algal blooms and dead zones
Water purification
Accumulation of fish waste
Select the benefits associated with growing Kelp (Seaweed)
Require no inputs
Can be consumed with minimal processing
It is an excellent substitute for fish
It only requires a small area of land to grow
Fast growth rate
Even more advantages of seaweed farming?
Carbon sequestration
It can be practiced in only a few small areas of the ocean
Reduces ocean acidification
Prevents algal blooms
Weakens ocean ecosystems
What is the name of the gene editing tool used for genetically modifying foods?
CRIMPER (CAR 5)
CRISPR (CAS 9)
Gene Editor 9
Biotech 9
Select the practices that can help reduce food waste
Agroprocessing
Transporting produce in baskets
Transporting produce in plastic bags
Transporting produce during cooler parts of the day
Transporting produce during the hottest times of the day
Employing better handling and transportation practices ensures that
Consumers purchase more fruits and vegetables
The fruits and vegetable reach the consumer in good condition
The produce has a shorter shelf life
The health of the population improves
The produce has a longer shelf life
The problem of food security for all is not just a matter of food production but rather a matter of distribution of the food that is produced so that less is wasted and fewer people go hungry.
True
False
Fish farming in the open ocean reduces many of the harmful effects of fish farming and since the ocean represents the majority of the Earth's surface farming in the ocean may be more sustainable than farming on land.
True
False
Vertical farming does not maximize land space used for food production
True
False
