Exemplar Problems
Question:
Find out how much cellulose is made by all the plants in the biosphere and compare it with how much of paper is manufactured by man and hence what is the consumption of plant material by man annually. What a loss of vegetation!
Answer:
Estimating the total amount of cellulose produced by all plants in the biosphere is a complex task, as it varies widely depending on factors such as plant species, geographic location, climate, and environmental conditions. However, we can provide a rough estimate based on available data.
- Cellulose Production by Plants:
- Cellulose is the primary structural component of plant cell walls, providing rigidity and support to plant structures.
- The estimated annual cellulose production by all plants on Earth is in the range of 10 to 20 billion metric tons (10^10 to 2 x 10^10 metric tons). This includes cellulose from trees, shrubs, grasses, and other vegetation.
- Paper Production by Humans:
- Paper production by humans is a significant industry worldwide, and it contributes to deforestation and the consumption of plant material.
- The global paper and paperboard production in recent years has been around 400 to 450 million metric tons per year (4 x 10^8 to 4.5 x 10^8 metric tons).
- Consumption of Plant Material by Humans:
- To estimate the annual consumption of plant material by humans, we need to consider not only paper but also other products like wood, textiles, food, and more.
- The total consumption of plant material by humans, including wood, paper, food, and other products, is estimated to be several billion metric tons per year.
