apex environmental science

The answer is; B

Increasing human population put enormous pressure on natural resources of the planet. This is because increasing human population is directly proportional to increasing energy demands and food. Therefore meeting these needs become more and more  difficult and requires innovations. Space also becomes inadequate.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
