Which practice is harmful to the land? a. using animal waste as fertilizer b. composting with peels from commercial fruit c. throwing paint cans in the garbage d. cutting the lawn with a gas-powered mower

C. throwing paint cans in the garbage

Explanation:

Throwing paint cans in the garbage may result in the content leaking out if not handled properly.

However cutting the lawn will help in providing the soil with more organic matter while the gas powered mower may release gas which will pollute the air but not the land.

Composting and use of animal waste is also useful.
