What are the five biggest environmental problems?
The negative impacts of anthropogenic activities on the biophysical environment can cause environmental concerns. Environmental challenges are addressed by environmentalism, a social and environmental movement, through advocacy, education, and activism.
The five megatrends pose huge worldwide risks to planet Earth, posing difficulties that must be addressed if the globe is to continue to be a safe haven for people and other animals. Environmental protection is the activity of safeguarding the natural environment on an individual, organisational, or governmental level, with the goal of benefiting both the environment and humans.
Five major issues of Environment
1: Air pollution: Carbon overloading of the atmosphere and ocean waters, warmer air, soils, and ocean surface waters arise from CO2 in the atmosphere absorbing and re-emitting infrared-wavelength radiation, which is good because the earth would otherwise be frozen solid. Unfortunately, the amount of carbon in the atmosphere is currently considerable.
CO2 levels in the atmosphere have risen from 280 parts per million (ppm) 200 years ago to roughly 400 ppm presently, mainly due to fossil fuel combustion, agricultural deforestation, and industrial activities. That's a new high in terms of both size and speed. As a consequence, the climate has been thrown into disarray. Carbon overloading is just one type of pollution created by coal, oil, gas, and wood combustion. According to the World Health Organization, one out of every nine deaths is caused by diseases induced by dirty air.
Solution for air pollution
Renewable energy should be used instead of fossil fuels. Start doing reforestation by reducing agricultural emissions. Industrial procedures must be altered. The good news is that clean energy is plentiful; all that is required is for it to be harvested. Many people believe that a world powered entirely by renewable energy is already possible with current technology.
The bad news is that, despite the fact that renewable energy infrastructure - solar panels, wind turbines, energy storage and distribution systems - is already widely available and getting cheaper and more efficient all the time, experts say we're not using it fast enough to avoid catastrophic climate change. Policy and financial barriers must yet be overcome.
2: Deforestation: Wild forests, particularly in the tropics, are being destroyed to make way for cattle ranching, soybean or palm oil plantations, or other agricultural monocultures.
Forests represent around 30% of the planet's surface area now, which is about half of what they were before agriculture began around 11,000 years ago. Around 7.3 million hectares (18 million acres) of forest are destroyed each year, mostly in the tropics. Tropical forests used to cover around 15% of the planet's land area; now they only cover about 6% or 7% of the planet's land area. Much of the remaining land has been devastated by logging and fire.
Natural forests are not only biodiversity reserves, but they also operate as carbon sinks, eliminating carbon from the atmosphere and oceans.
Solution for deforestation
Conserve what's left of natural forests and replant damaged regions with native tree species to rehabilitate degraded areas. This necessitates good governance, but many tropical countries are still developing, with growing populations, uneven rule of law, and pervasive cronyism and bribery in land allocation.
3: Species extinction:Wild animals are hunted to extinction on land for bushmeat, ivory, and "medicinal" items. Large commercial fishing vessels equipped with base trawling or nets sweep entire fish populations out to sea. Habitat devastation and loss are also major contributors to an unprecedented extinction event initiated by a single species: humans.
Solution for species extinction
To prevent additional biodiversity loss, concerted measures are required. One aspect of this is protecting and restoring habitats; another is preventing poaching and animal trading.
4: Soil Degradation: Overgrazing, monoculture planting, erosion, soil compaction, pollution exposure, and land-use conversion are just a few of the ways soils are harmed.
Solution: No-till agriculture, crop rotation, and water-retention through terrace-building are just a few of the soil conservation and restoration approaches available.
5: Over-Population:The human population is steadily expanding over the world. At the outset of the twentieth century, humanity totalled 1.6 billion people; we now number around 7.5 billion. By 2050, the world's population is predicted to be over 10 billion people. Global population growth, combined with increased income, is putting increasing pressure on key natural resources like water.
Solution for over population: The average number of births per woman lowers dramatically when women are allowed to choose their own reproduction and have access to education and basic social services.
All these matters are worthy to work upon because it is directly linked to our as well as our future generation survival. We already know the solutions. It just depends upon our will whether to work on them or not.
