Answer 1

Answer:

A. 1 & 2

• Correct Answer: Option A) 1 & 2

• One way to control pollution is by legally banning harmful substances.

• This statement is correct. Legal frameworks and regulations are essential tools in pollution control. Many countries have implemented laws that ban or restrict the use of harmful substances like certain pesticides, chlorofluorocarbons (CFCs), lead in gasoline, and various toxic chemicals. These legal bans have proven effective in reducing pollution.

• Alternatives to pollutants can help in pollution mitigation.

• This statement is also correct. Finding and implementing alternatives to polluting substances or processes is a key strategy in pollution control. Examples include replacing fossil fuels with renewable energy, using biodegradable materials instead of plastics, and developing cleaner production technologies.

• There is no way to control pollution once it has started.

• This statement is incorrect. There are numerous methods to control and remediate pollution after it has occurred, including waste treatment, environmental cleanup operations, air scrubbers, water filtration systems, and bioremediation techniques. While prevention is preferable, remediation and control of existing pollution are possible and practiced worldwide.
