Question

Which of the following is a disadvantage of using biofuels?

(a) it is cost effective
(b) removal of vast areas of arable land.

(c) it causes pollution
(d) both (a) & (b)​

Answer 1

Explanation:

True, a plant-based fuel comes from a renewable source, while fossil fuels will eventually run out. ... Likewise, the fertilizer, water and land required to produce enough biofuel to reduce fossil fuel consumption significantly can create other problems, ranging from increased pollution to decreased access to food.

Answer 2

Answer :

The answer will be D - both a & b.

Explanation :

Disadvantages of using bio fuels are that they are cost effective as well as they result in the removal of vast area of arable land.

• What are bio fuels ?

Bio fuels are naturally obtained fuels made by the decomposition of organic matter under high pressure and temperature for a long period of time.

• Why are bio fuels are Cost Effective ?

These are the following reasons :

1. Used extensively in key industries, hence is a profitable business.
2. As it's easy to consume that is the reason it is in demand and the amount of these fuels is not unlimited so as to fulfil requirements of a large population.
3. As the bio fuels takes a lot of time to be produced, but are consumed daily on a large scale and hence, the amount is decreasing.
4. It is a tough task to mine out the fuels as it is usually found under sea and meters below the land. This raises the cost of labour and machine maintenance which further increases the selling prices.

• Why bio fuels result in Removal of vast areas of arable lands ?

This is due to following reasons :

1. They are found mainly in forests, hence in order to obtain the bio fuels the forests are deforested and turned into mining sights.
2. The areas where traces of bio fuels are examined those areas are put under the mining projects.
