Unit Two

Question 1

Biodegradable

Answer 1

That it has the ability to decompose naturally and harmlessly. So-called biodegradable packaging helps limit the number of harmful chemicals that are released into the atmosphere.

Question 2

Biodiversity

Answer 2

The number and variety of plant and animal species that exist in a particular environmental area or in the world in general, or the problem of preserving and protecting it.

Question 3

Climate change

Answer 3

Changes to long standing climate patterns due to increasing average global temperatures

Question 4

Deforestation

Answer 4

The felling of trees in a large area; destruction of forests by people. Deforestation is destroying large areas of rainforest.

Question 5

Desertification

Answer 5

The process by which the land becomes desert.

Question 6

Natural resources

Answer 6

Things like minerals, forests, coal, etc. that exist in a place and can be used by people. Some natural resources, such as natural gas and fossil fuels, cannot be replaced.

Question 7

Nonrenewable energy

Answer 7

sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.

Question 8

Renewable energy

Answer 8

It describes a form of energy that can be produced as quickly as it is used. Renewable energy sources such as wind and wave energy.Na

Question 9

Sustainable development

Answer 9

A development that is causing little or no harm to the environment and can therefore continue for a long time.

Question 10

Carbon footprint

Answer 10

a measurement of the amount of carbon-dioxide a person adds to the atmosphere

Question 11

Toxic

Answer 11

an adjective used to describe the environment that is contaminated with pollutants and other hazardous substances. This could include a polluted river, a contaminated lake, or a toxic waste site.

Question 12

Ecosystem

Answer 12

a biological community of interacting organisms and their physical environment.

Question 13

Species

Answer 13

1. : a class of things of the same kind and with the same name : kind. 2. : a category of living things that ranks below a genus, is made up of related individuals able to produce fertile offspring, and is identified by a two-part scientific name.

Question 14

Pollution

Answer 14

the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects.

Question 15

Sustainability

Answer 15

Sustainability

Question 16

Light pollution significantly impacts the environment, affecting biodiversity and disrupting ecosystems. Excessive artificial lighting can interfere with the natural behaviors of species, such as nesting patterns of birds and mating rituals of insects, thereby threatening their survival. This type of pollution also contributes to the larger issue of climate change, as the energy used in unnecessary lighting often comes from nonrenewable energy sources, increasing the carbon footprint. To address these issues, promoting sustainable development practices that incorporate energy-efficient lighting solutions and reduce toxic emissions is crucial. By focusing on reducing light pollution, we can support biodiversity, enhance sustainability, and mitigate the broader environmental impacts associated with our energy consumption.

Question 17

1. According to the paragraph, how does light pollution contribute to climate change?

Answer 17

By using energy from nonrenewable sources (correct answer)
By reducing the carbon footprint
By increasing the natural behaviors of species
By enhancing biodiversity
