Hint: The burning of fossil fuels, the release of chemicals into the environment, the reduction of forest cover and the rapid growth of agriculture, construction and industrial activities release carbon dioxide into the atmosphere and change the equilibrium of the climate system.

Complete answer:
By causing changes in the Earth's atmosphere in the form of greenhouse gases, aerosols, etc., human activities lead to climate change. Greenhouse gases and aerosols impact the atmosphere by altering incoming solar radiation and outgoing infrared (thermal) radiation that is part of the energy balance of the Earth.
Human actions that have the biggest effect on global warming are the combustion of fossil fuels such as coal, oil and natural gas to produce vast quantities of electricity.
Deforestation has a direct impact on habitats and endangered species for homes, livestock, and industry. Trees consume environmental carbon dioxide emissions and accumulated carbon is also emitted into the atmosphere as vast areas are cleared by deforestation.
Growing sea levels over the last century, increasing global temperatures, warming seas, declining Greenland and Antarctic ice sheets, diminishing Arctic sea ice, glacial retreat, extreme high-temperature events, acidification of the oceans, and reduced snow cover are evidence of climate change.
Biological magnification also refers to the mechanism by which such contaminants, such as chemicals or heavy metals, travel up the food chain, enter rivers or lakes and are ingested by aquatic species, such as fish, which are eaten by large birds, animals or humans in turn. When they pass up the chain, the substances become concentrated in tissues or internal organs.
A deep layer in the stratosphere is the ozone layer. Encircling the Earth with massive concentrations of ozone in it. The membrane protects the whole of the Planet from much of the sun's harmful ultraviolet radiation.
Then more UV rays will enter the earth if this ozone becomes exhausted. It has detrimental effects on farming, plant life on the land, natural habitats, etc. It also causes marine life to be harmed.

Global warming can indirectly cause rises in a variety of adverse health effects, including malnutrition, diarrhoea, accidents, cardiovascular and respiratory disorders, and water-borne and insect-transmitted diseases, etc., along with consequent changes in food and water supplies.
