I think your answer would be biomass. If the earth uses too much of it, it will take too long to replenish. Hope this helped could I possibly get brainliest?
Answer:
Age is a problem for both types of countries, here's why
Explanation:
In developing countries age is a problem because this state has to provide jobs and care for growing children, and providing education for them is expensive and time consuming, not to mention basic needs like housing and food. It's hard for developed countries too because these countries have to deal with an older population that is declining in health. The state needs to provide assisted living and care for this part of the population.
The hypothesis of continental drift came up in 1910 by German scientist Alfred Wegener. The idea is that when you look at a map south America and Africa seem to fit perfectly together. this would have made one super Continent called Pangaea. so in order for it to get to where it is today something must have happened that is where the idea of floating continents came in. this theory is no longer relevant as now scientists found they would have to adjust to fit the size if both continents. I hope this helps.
