what are the harmful effects of developmental activities by humans on various spheres.
Answers
1. Overpopulation
Survival used to mean repopulating. That, however, is quickly becoming true for the opposite as we reach the maximum carrying capacity that our planet can sustain.
Overpopulation has grown into an epidemic since mortality rates have decreased, medicine has improved, and methods of industrial farming were introduced, thus keeping humans alive for much longer and increasing the total population.
The effects of overpopulation are quite severe, with one of the most severe being the degradation of the environment.
2. Pollution
Pollution is everywhere. From the trash thrown out on the freeway, to the millions of metric tons of pollution pumped into the atmosphere every year- it's obvious, pollution and waste are inescapable.
Pollution is so bad that to date, 2.4 billion people do not have access to clean watersources. Humanity is continuously polluting indispensable resources like air, water, and soil which requires millions of years to replenish.
Air is arguably the most polluted with the US producing 147 million metric tons of air pollution each year alone.
In 1950, smog was so bad in LA that the ground level ozone (atmospheric gas that is great in the atmosphere, not so much on the ground) surpassed 500 parts per billion volume (ppbv)- well above the National Ambient Air Quality Standard of 75 ppbv .
3. Global Warming
Global warming is arguably the greatest cause of impact to the environment. The largest of causes emanating through CO₂ levels from respiration to more detrimental causes like burning fossil fuels and deforestation.
At any rate, humans are consistently increasing CO₂ levels globally- every year. The highest level of CO₂ in recorded history before 1950 was about 300 parts per million. However, current measurements of CO₂ levels have exceeded above 400 PPM, abolishing every record dating back 400,000 years.
The increase of CO₂ emissions has contributed to the planet's average temperature increasingalmost a whole degree.
4. Climate Change
Climate change is closely connected to historical developement of industry and technology. As global temperatures increase, Earth's weather patterns will drastically change. While some areas will experience longer growing seasons, others will become barren wastelands as water will deplete in vast areas, turning once floral regions into deserts.
The increase will impact weather patterns, promising more intense hurricanes in both size and frequency, as well as intensifying and prolonging droughts and heat waves. But air pollution does not just affect the environment.
The evidence is mounting that poor air quality and rising temperatures are ruining delicate ecosystems, even leading to increased asthma and cancer.
5. Genetic Modification
Genetically modified organisms (GMOs) have been a major contributor to the survival and prosperity of humans.
But GMO's are not always intentional. For years humans have used glyphosate, a herbicide designed to eliminate weeds - the biggest threat to any plant. However, just as humans have a learning immune system, certain weeds have developed a resistance to 22 of 25 known herbicides, with 249 species of weeds completely immune according to
