Answer:
Explanation:
Total population in our world is 753.04crore . So, we know that each human consumes oxygen which is equivalent to 5 medium sized trees hence the total amount of trees required to fulfil the need for oxygen for 7.7 billion population is immense.
Nearly 3765.2crore trees needs to be the supplier but the amount of increasing population size and reckless deforestation will eventually barren acres of forest and trees.
Accordingly after few decades there will be surge for oxygen and human population will decrease at a higher rate. Thus, we need to stop cutting trees and promote planting them.
Answer:
Approximately 38.5 billion trees are required for the world population to provide oxygen for their respiration. Tree gives us oxygen when they use energy of photon from the sunlight to make food glucose. In a year a human breath about 9.5 tonnes of air but the fact is oxygen is about 23% in that air. In past few years about trillions of trees are cut to provide a land for the industrial area. World population is increasing and the number of trees is decreasing and this will cause a serious problem in the future. In future there will be no sufficient amount of tress for the population to survive.
