Question

Explain why a society usually would not determine that a degree of 0 per cent air cleanliness is optimal.

Short answer

The socially ideal degree of contamination or level of air tidiness happens where the marginal cost of contamination decrease is equivalent to the marginal cost of contamination reduction.

Step-by-step solution

Introduction

At points lower than that the marginal benefit from clean air increments than the marginal benefit from cleaning the air. The socially helpful degree of contamination or clear air is given where the marginal benefit is equivalent to the marginal cost. As it is difficult to live in a too grimy climate, having a too perfect environment is likewise unrealistic.

Explanation

Contamination can never be headed to anything. A $100\%$ level of air tidiness would suggest no level of contamination. On the off chance that we attempt to accomplish a $100\%$level of air tidiness, this would imply that the cost of this decrease in contamination surpasses the benefit from this decrease. Consequently, it isn't doable to have a $100\%$ level of air tidiness. Besides, our regular framework has the ability to absorb some level of contamination. Consequently, some level of contamination is consistently ideal.
