People today are increasingly aware of the impact vast factory farms have on the environment, and seek to return to smaller farms and even urban gardens. As “eating local” rises in popularity, urban land is being reclaimed for traditional agriculture and the environment . And as consumers we can lessen our human impact on the environment by demanding better quality products, environmentally ethical practices from industries and a shift toward sustainable energy. Air Pollution. One bit of good news about our human impact on the environment is that air pollution is lowering and air quality is increasing. Climate and Environment. Human impact on the oceans is growing — and climate change is the biggest culprit The researchers used global-scale data to map the cumulative impacts of human Author: Chelsea Harvey.


Humans – the real threat to life on Earth | Environment | The Guardian


Take a look at 10 ways humans have left a footprint that has forever changed the environment and the planet. We as humans have become dependent on luxuries such as cars, houses, and even our cell phones. But what does our love for manufactured metallic and human impact on the environment article goods do to the environment? Human activity can be directly attributed to the cause of hundreds of extinctions in the last two centuries, versus the millions of years that extinctions naturally occur.

Human impact on the environment has become one of the main topics for university staff all over the world. While they search for the answer, the public needs to do its part. At least, you need to be aware of all the factors that contribute to this state and share the knowledge.

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, human impact on the environment article, 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. Humans require space, and lots of it whether it is for farmland, or industries which also takes up tons of space. Another issue is our dependency on coal and fossil fuels for energy, the larger the population, the more fossil fuels will be used. Although processed materials are necessary to power the cities, the previous assessment tells us that the planet can only sustain so much damage until it will begin to damage us.

Pollution is everywhere. Pollution is so bad that to date, 2. 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 million metric tons of air pollution each year alone. People thought human impact on the environment article were under foreign attack as the smog burned their eyes and left an odor of bleach in the air.

That is when the devastating effect of aerosols was discovered. While air quality in the US has slightly improved, the quality in developing countries continues to plummet as smog continuously blocks out the sun in human impact on the environment article dense shroud of pollution.

This is just one of the issues we have to tackle in near future. Global warming is arguably the greatest cause of impact to the environment. As the Temperature increases, arctic land ice and glaciers melt which causes the ocean levels to rise at a rate of 3. 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 rates in humans. Genetically modified organisms GMOs have been a major contributor to the survival and prosperity of humans.

GMO's are selected bred crops or crops that have had DNA directly implanted into it human impact on the environment article order to give an advantage to the crop, whether that be to sustain colder temperatures, require less water, or yield more product.

But GMO's are not always intentional. However, just as humans have a learning immune system, certain weeds have developed a resistance to 22 of 25 known herbicides, with species of weeds completely immune according to the latest scientific report. One of the only solutions is to till the land, turning over the soil to kill the weeds and give an early advantage to the planted crops.

The disadvantage of tilling, however, human impact on the environment article, is that it causes the soil to dry faster and kills off good bacteria, making its fertile lifespan significantly shorter. To replenish the depleted soil, fertilizer is used, which introduces a whole new set of problems to the environment and can be disastrous for local agriculture in the long run.

The acidity depletes the calcium concentrations, making it difficult for crustaceans to build their shell, leaving them vulnerable without their armor. However, acidification is not the only watery threat as there are other human activities causing severe changes. Not only is garbage introduced into the oceans, but also the excessive amounts of fertilizer that finds its way into the ocean through rains, floods, winds, or dumped in excess right into the largest producer of oxygen we have.

Phytoplankton and algae thrive off human impact on the environment article nitrogen, causing excessive growth in what is known as " red tides" or "brown tides" in areas with high concentrations of nitrogen.

The brown tide is caused by human impact on the environment article rapid growth of billions of algae, which deplete water bodies of oxygen and cause poison to accumulate in all life that consumes it, including fish and birds. But water pollution does not end there. Year after year, millions of tons of garbage is dumped into the ocean. Since the garbage mainly consists of plastics, it is largely indissoluble.

The garbage accumulates in large vortexes across the ocean. Marine life, including the loggerhead sea turtles, are tricked into thinking they are eating food when really it is only a floating plastic bag or other poisonous plastic that will cause starvation or suffocation to any unfortunate animal that mistakenly ingests it, human impact on the environment article. Pollution is the number one threat to all aquatic life and is lead cause of reduced biodiversity.

This is really sad given that water and water life-forms are some of the most important natural resources at our disposal. With an exponential expansion in human beings, more food, materials, and shelter are being manufactured at stupendous rates, human impact on the environment article, mostly stemming from forestry. Forests are cleared to make way for new humans, which in turn, makes more humans, human impact on the environment article can see the problem.

With trees being one of the largest producers of oxygen, clearly that is not a good thing for humans- and especially not for the animals that call the forest home. With millions of different species that live in forests, deforestation is a major threat to their survival and a big conservation issue.

It also increases the greenhouse gases within the atmosphere which leads to further global warming. Such human activities need to stop if we wish to survive. When the rain falls, it accumulates in water bodies which are especially harmful to lakes and small bodies of water. The ground surrounding the water soaks up the acid, depleting the soil of essential nutrients. Trees that absorb the acid accumulate toxins that damage leaves and slowly human impact on the environment article large areas of forest.

Acid rain has also been known to completely eliminate entire species of fish, causing a snowball effect of damage to the ecosystem that relies on diverse organisms to sustain the environment. The ozone layer is renowned for its ability to absorb harmful UV rays that would otherwise be detrimental to the health of all walks of life, human impact on the environment article. Without an ozone layer, walking outside would be unbearable. Ozone is made up of three bonded oxygen's that float up to the stratosphere where they absorb a substantial amount of UV radiation, protecting all life down below.

The human impact is devastating for plants that are extremely sensitive to UV light including wheat and barleytwo indispensable crops to humans. Until then, slap on that sunscreen and be safe out there. It is imperative that we support the earth that we live on, but no matter what, the earth will live on.

Human impacts the natural habitat in so many ways and we need to be aware of our personal environmental input. Whether we live with it or not solely depends on the decisions and actions we make next. Mother nature is an unrelenting, unforgiving force, human impact on the environment article, so it is probably best if we treat her well, and maybe, just maybe we can make up for the damage that has already been dealt.

The best time to act, was yesterday, the best we can do is today, but if we wait for tomorrow, it may just be too late. Society needs to help itself in order to survive. Asian Development Bank.
