Air pollution is a mixture of solid particles and gases that are detrimental to human health and the planet. We compiled a list of the main causes of air pollution in general:
China generates the most pollution and is the major contributor to the increase of CO2 levels with 28% of the world’s CO2 emissions (or 10.06 GT). Up next we have the United States with 15% (or 5.41GT) and India with 7% (or 2.65GT)
Both short-term and long-term exposure to high levels of air pollution increases the risk of respiratory infections, heart diseases and lung cancer in humans but also has a major impact on the process of plant evolution by preventing photosynthesis and, in many cases, with serious consequences on the purification of the air we breathe. It also contributes to the depletion of the ozone layer, global warming, the greenhouse effect and acid rains.
Water pollution is when a lake, river, ocean, stream, aquifer, or any body of water is contaminated by harmful substances, degrading the quality of the water. Some of the causes are:
Contaminated waters caused 1.8 million deaths in 2015 majorly due to waterborne pathogens, which come from illegal releases from sewage facilities
Water pollution can reduce the levels of oxygen in the water, suffocating the local wildlife and can reduce an organism's life span
Climate change is a global phenomenon described by the shifting of the usual climate of the planet that is mostly caused by human activities, such as temperature, rain and wind changes, mainly caused by the "greenhouse effect".
Gases that contribute include: Water vapor, CO2, Methane, Nitrous Oxide and Chlorofluorocarbons.
Climate change can put 20-30% of all species in risk by destroying their natural habitats and ecosystems
The melting of several ice sheets, increasing the global sea level rise.
The increase of the concentration of carbon dioxide, making the water more acidic and the increase of the temperature, killing 70-100% of coral reefs.
Wildfires, which can destroy communities and release a lot of carbon dioxide into the atmosphere, causing high levels of extinction
