Impacts on the Enviroment

Question 1

Farming

Answer 1

The chemicals in fertilisers don’t stay in fields
This leads to pollution of nearby land, rivers or wetlands
Agricultural processes are responsible for 14% of global greenhouse gas emissions
The livestock sector is responsible for 18% of all greenhouse gas production

Question 2

Deforestation

Answer 2

Fewer forests means more greenhouse gases being released into the environment
Trees help preserve the water cycle
Without them desertification may occur more quickly

Question 3

Mining

Answer 3

Impact vegetation on the surface
Extraction causes erosion, dust and noise
Reforestation has begun in areas damaged by mining
Pollution and disruption to the environment

Question 4

Oil and gas drilling

Answer 4

Heavy oils affect organisms ability to respire and feed
Phytochemicals are absorbed into organs and cells which have lethal toxic effects
Loss of habitats can alter ecosystems dynamics
Acid rain weakens plant life
Water quality degraded
Light pollution can change migration patterns

Question 5

Oceanic pollution

Answer 5

Half of all ocean pollution comes from activities on land
Out of the 100 million tons we produce of plastic, 10 million ends up in the ocean
Oceans absorbing CO2 makes them more acidic

Question 6

How can we stop oceanic pollution?

Answer 6

Reduce, reuse, recycle
Proper disposal of plastic bags
Biodegradable packaging

Question 7

Atmospheric pollution

Answer 7

Use of electricity, fuels and transportation
Hazardous to public health
Lakes and waterways contaminated
