Based on the information in this table, the daily waste remained the same but the total waste has steadily increased. What are some possible explanations for this?

Hint: Think about population growth and its effects on the planet.

Answers

Answer:

With the growth of the population, the amount of waste produced rises. These two factors are correlated because despite the average amount of waste per day being produced per day stays the same, there are more people to create this waste, thus causing more waste per year. For example, if you had 4 friends and 20 candies between you, then the total candies is 20, and the average person gets 5 pieces. If you had 5 friends and 25 candies the next day, then the total amount of candies you have increases, but the average amount each person gets stays the same (5).

The daily waste remained the same but the total waste has steadily increased due to an increase in the population.

From the information that's given in the graph, we can infer that the increase in the population led to an increase in the total waste. In this case, the total waste in millions of tons per year will increase.

Despite that, the daily waste which is the pounds per day per person can still be the same. For example, let's say the population before was 100 people and the total waste was 2000 tons. Then the waste per person will be:

= 2000/100 = 20 tons per person.

Now let's say the population increases to 110 people and the total waste then increases to 2200 tons, then the waste per person will be:

= 2200/110

= 2 tons per person.

The above shows that despite the fact that there's an increase in total waste, the daily waste is still the same.
