Activities such as using water balloons, parties at parks or beaches, driving, and boats.
Explanation:
Water balloons harm the environment, as well as gatherings at places such as parks and beaches because of the waste and trash that is left. This can effect the animals as well as the environment. Boats because of the oil and chemicals it releases into the water. Lastly, driving releases gases and chemicals that are harmful not only to the environment but to humans.
