Tropical rainforests are sometimes cleared to make crops. These crops include plants that produce vegetable oils, such as palm oil. However, deforestation leads to great loss of biodiversity. A group of concerned scientists devised two possible solutions to the problem. The best solution will spare additional rainforests from clear-cutting and still provide local communities with a source of income.

Solution 1: Businesses buy oils only from certified deforestation-free areas. Oil producers use better management practices on non-forest land to increase crop yields.

Solution 2: Businesses switch to other types of vegetable oils that do not cause deforestation. For example, plants, such as corn and sunflowers, are grown in a grassland ecosystem.

Identify the best solution, and explain why the solution meets the criteria of the problem.
