The overall issue in which this game aims to explore and educate kids about is the water quality of New Zealands Rivers and streams. The concern being that kids and families can no longer swim in and enjoy them due to the pollution caused by cattle and cattle farms.
"Our rivers and lakes are central to our natural environment, economy and way of life in New Zealand. Freshwater supports the health of our native flora and fauna. It underpins much of the New Zealand economy – it is used to irrigate crops and pastures, dispose of or dilute trade wastes and sewage, produce hydro-electric energy, and is a tourist attraction." (http://www.mfe.govt.nz/fresh-water/about-fresh-water/fresh-water-new-zealand; Importance of fresh water)
The bolded text is the key issue in which we would like the kids to consider. Do we want to swim in poo?
"For Māori, fresh water is a taonga. All iwi and hapū have strong connections with local lakes and rivers, reflected in their whakapapa and history. This relationship with water is recognised under the Treaty of Waitangi. Healthy fresh water also provides mahinga kai (customary food and resource gathering)."(http://www.mfe.govt.nz/fresh-water/about-fresh-water/fresh-water-new-zealand; Importance of fresh water)
-Population growth and the 150 years of changing land use is putting pressure on our water.
-We have 145 million litres of fresh water per person per year. Although in some areas we do not have a good enough quality of water or enough of it.
-"This affects our native biodiversity and the extent water can provide for our needs, such as recreation, cultural wellbeing, tourism and economic production."
-There is a wide variety of needs for water that needs to be balanced.
-The aim is to have 90% of New Zealands water clean and swimmable by 2040.

"New Zealand’s dairy industry has a significant detrimental effect on our environment. The 2015 Environment Aotearoa report recorded a 28 per cent surge in the land area used for dairy farming over the last 10 years. This increase in the national dairy herd is causing a corresponding increase in compaction of land (at around 80 per cent of dairy farms), pollution of waterways and greenhouse gas emissions." (http://safe.org.nz/dirty-dairy; Safe for Animals: Dirty Dairy. )
-Animal excrement is the main source of pollution.
-A cow poos 15x more than a human.
-There is 6.7 million cows = 100million people worth of manure.
-60% of NZ waterways not fit to swim in. 2013 Ministry for the Environment figure.
-There is a correlation of the worst waterways being in dairy farm areas.
"Such is the scale of the problem that Massey University freshwater ecologist Mike Joy has said that if New Zealand's ecosystem continues to decline at the same rate as over the past 40 years, the country will have no native fish by 2050." http://safe.org.nz/dirty-dairy; Safe for Animals: Dirty Dairy. )
-Some farmers (not all) allow the cows direct access to streams or overflow of lagoons into the waterways.
-Even fencing them off the nutrients leach into the water. Like fertiliser and nitrogen. "The nutrient enrichment caused by dairy farming leads to loss of species, algal blooms and undrinkable water."
-Cows also contribute to our greenhouse gas emissions. through methane release in burping, excrement, and urine.
