During photosynthesis, plants take in carbon dioxide and water. Sugar and oxygen are by-products of photosynthesis. Since humans need oxygen to live, plants are essential for producing oxygen therefore cutting down the rain forests would be a negative effect. Another would be that rain forests contain a very large amount of plant and animal species that are wiped out when the rain forest is cut down. Some of them are even beneficial for medicine. A third related to the first is that when there are less plants taking in carbon dioxide, there is a larger concentration in the atmosphere. There is a large debate going on over wheter this larger concentration of carbon dioxide is causing global increases in temperature, leading to adverse conditions in parts of the Earth that are at or below sea-level and flooded by the subsequent rise in sea-levels.

There are several human impacts on the environment that people are slowly beginning to realize are having a negative effect. Things such as coal plants, leaving appliances plugged in when not using them, and the exhaust that comes from cars are just a few examples of negative human impacts on the environment.
How can humans affect islands?
Humans can have both positive and negative impacts on islands. Positively, human activities such as sustainable tourism can contribute to the local economy and conservation efforts. However, negative human impacts can include habitat destruction, introduction of invasive species, pollution, and climate change, which can lead to loss of biodiversity and damage to island ecosystems. It is important for humans to minimize their negative impacts and promote sustainable practices to preserve and protect island environments.
How does the rainforest impact humans?
The rainforest impacts us because it takes in all the nasty carbon dioxide and gives out oxygen in the process of photosynthesis. The rainforests around the world are slowing down global warming and if they go we'll all die.
What negative impacts does pollen have on humans?
Normally all impacts are indirect but positive, as the means by which plants propagate; but it can affect individuals as an allergen giving the condition of irritated nose and eyes we call "hay fever".
