Environmental issues
The set of challenges and problems facing Earth and its natural systems. From global warming and pollution to overpopulation and food waste, these issues are complex and interconnected.

Global Warming
Global warming is the long-term warming of the planet’s overall temperature. Though this warming trend has been going on for a long time, its pace has significantly increased in the last hundred years due to the burning of fossil fuels. As the human population has increased, so has the volume of fossil fuels burned. Fossil fuels include coal, oil, and natural gas, and burning them causes what is known as the “greenhouse effect” in Earth’s atmosphere.
+ INFO
Biodiversity Loss
Biodiversity loss is described as the loss of life on Earth at various levels, ranging from reductions in the genetic diversity to the collapse of entire ecosystems. In addition to its intrinsic value, biodiversity underpins ecosystem services, providing the backbone of the global economy.
+ INFO
Food Waste
Food waste is food that is intended for human consumption that is wasted and lost, and refers not only to food that consumers don’t finish at restaurants and are thrown out at home, but also raw materials and produce that are lost in the farming stage, harvesting processes, during transportation, and storage. Food waste can occur anywhere throughout the entire supply chain.
+ INFO
Plastic Pollution
Plastic pollution is the accumulation of plastic objects and particles in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastic pollution can afflict land, waterways and oceans.
+ INFO
Deforestation
Deforestation refers to the cutting, clearing, and removal of forest or related ecosystems into less bio-diverse ecosystems such as pasture, cropland, or plantations. Such a loss can only be caused and maintained by a continued human-induced or natural perturbation.
+ INFO
Air Pollution
Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.
+ INFO
Melting Ice Caps and Sea Level Rise
Since the early 1900s, many glaciers around the world have been rapidly melting. Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.
+ INFO
Food and Water Insecurity
Food insecurity is when a person is without reliable access to enough affordable, nutritious, healthy food. Famine is the most severe phase of food insecurity and means a complete lack of access to food and other basic needs. Water insecurity is the lack of adequate and safe water for a healthy and productive life.
+ INFO
Fast Fashion and Textile Waste
Fast fashion is a true menace on both the environment and society. This phenomenon refers to the overconsumption of clothes and the rapid renewal of fashion collections. Of the 100 billion garments produced each year, 92 million tonnes end up in landfills.
+ INFO
Overpopulation
Overpopulation is the human population rises to an extent exceeding the carrying capacity of the ecological setting. The numbers of people might be more than the available essential materials for survival such as transport, water, shelter, food or social amenities. This regularly contributes to environmental deterioration, worsening in the quality of life, or even the disintegration of the population.
