Humans need to maintain enough space and resources to increase the earth's capacity for all species. They have to make sure that they and other people have enough to survive.
This is known as the carrying capacity, which is the maximum population size that an environment can sustain indefinitely with the available resources. When a population stabilizes and consumes just enough resources to keep the population steady, it has reached the carrying capacity of its environment.
Wastage does not kill you. Not having enough to survive does. Those organisms that overproduce in normal times will produce barely enough in less fortunate times; those that can only produce enough in normal times will not produce enough in lesser times, and die off.
there are enough resources for each new member of the population to use
Many people worked all the time and barely made enough money to survive
Many people worked all the time and made barely enough money to survive. Apex :)
Not enough food or water or other resources to care for the population. Too much use of oil and all resources to create homes and everything else to maintain a population.

The barley was barely dry enough to harvest.
Yes, it is. It means scarcely or narrowly (only just sufficient) and modifies adjectives and adverbs. In "there was barely enough time" barely modifies enough, an adjective modifying the noun time.
Malthus proposed that human populations grow exponentially while resources grow arithmetically, leading to competition for limited resources. He argued that this competition would result in a struggle for survival, with only the fittest individuals able to access enough resources to survive and reproduce. Malthus's theory influenced the development of evolutionary thought and population studies.
A population's carrying capacity is the amount of organisms a certain environment can sustain. If the number of organisms exceeds carrying capacity the resources in the environment will be depleted resulting in a carrying capacity drop followed by a drop in the population of organisms.
