Daily human activities impact the ecosystem in innumerable ways. Human activities that pollute or disrupt the environment and the ecosystem are most common such as driving a car, or using a chemical product that pollutes the environment, throwing a way trash, littering etc. Humans also can interact with the ecosystem in positive ways by learning and engaging with nature in a way that leaves no harm such as observing birds or going on a hike. In addition humans can impact the ecosystem around them by hunting or killing animal species or plant life in the areas surrounding them which generally has a negative impact on the ecosystem. 

humans manufacture fake sugar that's low in calories and use it as a sugar substitute. Our bodies don't absorb most of these sugar substitutes. We excrete them through urine and feces, which pass into the water. The marine plants and animals that live in these waters consume the sugar substitutes,which may affect their growth.
