What are 3 simple changes to your daily routine you can add to save water?
Any three of the following:
Less baths/more showers;
Check for leaks/water pressure;
Turn off water when not using it;
Checking for leaks;
Wash dishes and clothes manually if the dishwasher or washing machine are full.
Bob thinks that he shouldn’t conserve water because there are methods to convert salty water into drinkable water. Explain to him why his reasoning is wrong.
Because the majority of drinkable water still comes from resources (like rivers and lakes) with a limited amount of freshwater.
DAILY DOUBLE!
TRUE OR FALSE:
Water conservation does not impact global warming.
False.
DAILY DOUBLE!
Jake drinks 1 L of water a day, but he always takes a bath everyday and he never turns off sink water when he doesn’t use it.
Rob drinks 1.3 L of water a day, but he takes a shower four times a week and turns off sink water when he doesn’t use it.
Who saves the MOST amount of water?
Rob, because, although he drinks more water than Jake, his ways save more water than Jake’s do.
Which of the following is NOT a way to conserve water?
Taking more showers than baths;
Collecting rainwater to water plants;
Flushing the toilet every time you use it;
Monitoring leaks.
C (flushing the toilet every time you use it).
How will conserving water affect future generations? Positively or negatively? Why?
Positively, because they will have access to more potable water.
DAILY DOUBLE!
What % of water is the human body made of?
Around 60%.
Which type of irrigation saves the MOST amount of water?
Surface irrigation
Sprinkler irrigation
Center pivot irrigation
Drip irrigation
D (drip irrigation).
What are 3 ways to conserve water in agriculture?
Any three of the following:
Collecting rainwater to water plants;
Plant plants that don’t require too much water;
Use drip irrigation systems to water plants, as it is the most efficient type of irrigation for water conservation;
Reduce tillage frequency;
Give attention to soil quality, as a good soil can better hold moisture and can keep more water;
Give attention to soil quality, as a good soil can better hold moisture and can keep more water.
Why is water conservation important? Name three reasons.
Any three of the following:
Water is essential for the creation of human bodies;
Water is essential for the survival of all living organisms and for the welfare of ecosystems;
The amount of potable water is extremely limited, and therefore should be conserved as much as possible;
Conserving water lowers the carbon impact;
Conserving water keeps more in aquatic ecosystems filled with aquatic organisms, thus safeguarding their wellbeing and the one of their ecosystems.
Which of the following is not an appropriate way to conserve water?
Reusing non-potable water for industrial machines;
Using wastewater to clean industrial buildings;
Install systems that treat wastewater and convert it into water for toilet flushes;
Planting plants that do not require much water.
B (using wastewater to clean industrial buildings).
What is water conservation?
Water conservation is the action of saving water to reduce carbon footprint, to save energy and to assure a future for the generations to come.
In what ways is water used for energy?
Filter
Heat
Pump water
Explain why the water in lakes and rivers is being consumed more than the one in oceans and seas, and select which environments’ water should have the priority of being conserved.
Water in lakes and rivers are being consumed more because it is fresh and potable water, and therefore has more utility than salty water in oceans and seas. Because fresh water’s quantity is more limited and essential for all living organisms, it should have the priority to be conserved.
Choose the room of the house that uses the most amount of water, and name two reasons for your choice.
Bathroom, for:
Toilet flushes;
Baths and showers;
Washing machine;
Sink water.
There are three environments of three similar ecosystems.
Ecosystem A has access to 5600 L of water.
Ecosystem B has access to 3500 L of water.
Ecosystem C has access to 4000 L of water.
Suddenly, humans decide to take 10% of the water every year from these ecosystems for their use. After three years, however, they decided to reduce the water intake of the ecosystem with the lowest amount of water. In three years, which ecosystem should start to conserve its water? What do you think will happen to that ecosystem in three years?
Ecosystem B, as it has the lowest amount of water.
Due to the low amounts of water, the ecosystem will be less stable.
What are 3 ways to conserve water in industry?
Any three of the following:
Install water saving equipments for machines that use water;
Reuse and recycle water, as even non-drinkable water can be utilized for some industrial machines;
Install monitoring systems that daily check the water pressure meter and water flow meter in order to identify leaks;
Minimize usage of water in cleaning and use “dry” alternatives that don’t require water (like vacuuming or sweeping);
Use water-saving or “dry” equipment instead of technology that uses water;
Install sewage treatment plants to treat waste water and to recycle it for toilet flushes and cleaning.
There are two environments of two similar ecosystems, both of which are used by humans.
Ecosystem A currently has access to 5000 L of potable water, but every month 150 L are brought to cities for human use.
Ecosystem B currently has access to 7500 L of water, but every month 500 L are brought to cities for human use.
Both of these ecosystems’ water will neither increase nor be replenished.
Select the ecosystem that has more probability of survival and explain why.
Ecosystem A, because it is able to conserve more water, which keeps ecosystems healthy and stable.
There are two environments of two similar ecosystems.
Ecosystem A has access to 6000 L of freshwater.
Ecosystem B access to 3000 L of freshwater.
Suddenly, humans have decided to take 25% of the available water for their uses for two years.
Select the ecosystem which will be the MOST AFFECTED by water consumption, and select the ecosystem which, after two years, will have the LEAST AMOUNT of water.
Are both of these selected ecosystems negatively impacted? Should humans start to save water in these ecosystems? Why?
After two years, ecosystem A will be the MOST AFFECTED, as it has the largest difference between the initial and the final amount of water, while ecosystem B will be the one with the LEAST AMOUNT of water.
Both of these ecosystems are negatively impacted by water consumption and humans should start to save water from both ecosystems, as taking water from them renders them unstable and destroys the organisms living in them.
