Humans are negative for these reasons: space debris, pollution of the electromagnetic spectrum, liter, deforestation causing lower amounts of oxygen being produced, urban development possibly threatening animal and plant life, polluting the environment, destroying natural beauty, destroying farm land, and even affecting the humans that live there, and could spell extinction for nearly 1,200 species of plants and animals. CO2 emissions … list goes on .. try googling "negative effects of humans on earth" or something similar …
Positive effects of Plants: Actually, there are many benefits to having plants around us. As plants take in the air around them, they actually remove some of the airborne toxins and replenish the environment with oxygen. Peace lilies, bamboo, palms, and spider plants are thought to be especially effective at clearing the air of unpleasant toxic chemicals. In addition, studies have shown that plants also have a positive physiological effect on us, by providing relief from anxiety, lowering blood pressure, and adding to a general sense of well-being. Trees have a tremendous effect on air quality. Through the pores of leaf surfaces, trees absorb harmful pollutants produced by humans, including nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), carbon monoxide (CO). Small particulate matter—such as pollen, dust, smoke and ash—are trapped and filtered by leaves and branches. Some estimates conclude that 100 trees remove up to five tons of CO2, 400 pounds of ozone, and 300 pounds of small particulate matter. Trees keep us cooler, which means that less energy is used.
Try also googling "Positive effects of Plants/Trees" something along those lines!
