Does the water availability change globally?
Yes, water availability does change globally due to various factors such as climate change, population growth, and land use changes. Some regions may experience increased water scarcity due to droughts and increased demand, while others may see changes in water availability due to melting glaciers and changing precipitation patterns. These changes in water availability can have significant impacts on ecosystems, agriculture, and human populations, making it important to monitor and manage water resources on a global scale.
-
Why is money only limited in availability?
Money is limited in availability because it is a medium of exchange that represents the value of goods and services in an economy. The amount of money in circulation is controlled by central banks and governments to maintain stability and prevent inflation. If there was an unlimited supply of money, it would lose its value and lead to economic instability. Therefore, money is limited in availability to ensure that it retains its value and serves as an effective means of exchange.
