Cutting down trees will increase the carbon dioxide in the air since no trees would absorb the CO2. Cutting down trees will also make several animals extinct because with no trees the animals will have no home. Dynamite fishing will destroy coral reefs and kill many fishes. With many fishes gone, people will have less food sources. This is the same with oil spills. The water at the location of the oil spill will poison the organisms in there and will poison the people who will consume the water We can protect our natural resources by planting many trees, avoid illegal logging, dynamite fishing, and many other activities that can cause pollution.
