Question 6

Reforestation

Answer 6

A process of planting trees to replace trees that have been cut or burned down

Question 7

Reclamation

Answer 7

A process in which mined land is restored with soil and replanted with vegetation.

Question 8

Discovery of penicillin

Answer 8

this meant previously deadly illnesses could now be treated and more people survive to adulthood and have children

Question 9

Invention of vaccines

Answer 9

this meant many previously deadly illnesses could now be prevented entirely meaning more people survive to adulthood and have children.

Question 10

Invention of indoor plumbing and proper sanitation;

Answer 10

this prevented the spread of many diseases such as cholera, dysentery, typhoid, intestinal worms, and polio, causing less people to die.

Question 11

Increase in life expectancy

Answer 11

this means people are living longer and therefore using resources for longer.

Question 12

-More food is needed to feed the population, which means more land is needed for farming to produce this additional food.
-More land is needed for homes to house the population. This leads to areas of natural habitats such as forests and grasslands, being destroyed for human activities. An example of this is deforestation; where trees are cut down and the land is used for farming or building houses. This has led to a dramatic decrease in the amount of original forests remaining all over the world.

Answer 12

Destroying these forests has many impacts on the environment, not least to the animals that live in those forests. Taking away their habitats has pushed many species to the brink of extinction. Additionally when this land is then used for farming there are further impacts: the use of pesticides, the soil quality decreases, changes in biodiversity (the number of different species that live in an area), and a struggle for space.

Question 13

Pollution and Landfills:
As the human population increases, so does the amount of waste we produce. With humans using less and less reusable products and more and more disposable plastics, Landfills have become larger and larger as more waste is sent to them. About 60% of our garbage goes into landfills. Rainwater runoff from these landfills contains chemicals that can pollute the surrounding environment. This pollution can be devastating to many plant and animal species.

Answer 13

What can we do?

Reduce, reuse, recycle!
Reduce; limit your use of single use plastics (such as ziplock bags) in favor of reusable or compostable options.
Reuse; find another use for an item instead of just throwing it away.
Recycle; taking an item and repurposing it into something new.

Reforestation: planting trees to replace ones that have been removed. This allows us to bring the forests back and give the plant and animal life the chance to reclaim its habitat.
Reclamation: this is where land that has been mined is restored by returning lost soil, and replanting the plant life in the area.

Question 14

Drawing graphs:

Answer 14

1 point = Label axes with units
1 point = have a scale for the data on each axis
1 point = use a ruler to draw all lines
1 point = correctly plot the data points
1 point = make the graph large enough (do not draw a tiny graph)
