The greatest ecosystem that can be studied and partially comprehended is that of planet Earth. A system’s overall function and nourishment are provided by a combination of all living and nonliving organisms and habitats, which is known as an “ecosystem.” This comprises all living things found therein as well as all land, soil, water, and air. The totality of human actions and habits that have an impact on the delicate ecosystem of the Earth’s surface, both positively and negatively, is known as the “human impact on the environment.”

Activities of Humans that Impact the Environment

Agriculture is the human activity that most negatively affects the environment. The construction of new towns and dams, oil spills, commercial ocean fishing, and reliance on fossil fuels are additional activities that have an influence. Furthermore, emissions from companies, mines, automobiles, and landfills all have an effect on the ecosystem. The impact of these activities is increasing along with the human population.

Humans’ negative effects on the environment

Because of our ignorance of the detrimental effects that human activity has on the environment, human activities are changing the temperature of the planet. The majority of these effects are a result of both rising human populations and agriculture. The increasing population makes environmental problems like global warming, deforestation, pollution, rising sea levels, and overharvesting worse. These activities will make the Earth inhabitable if they are not reduced or regulated.

Worldwide Warming

Nitrogen and oxygen make up the majority of the gases that builds the Earth’s atmosphere. A greenhouse effect is produced by these gases in addition to lower amounts of other greenhouse gases such water vapor, carbon dioxide (CO2), nitrous oxide, and methane. In order to maintain the Earth’s temperature as it revolves around the sun, the greenhouse effect provides a worldwide insulator that lets in and stores just enough heat from the sun.

Deforestation

Another human activity that has contributed to damaging global warming is deforestation. Through a process known as photosynthesis, trees and other plants use CO2 to produce energy and oxygen (O2). Through this well-balanced process, the areas of the Earth with forests supported the environment. However, deforestation has been further accelerated by human activities, particularly agriculture.

Humans have been poisoning and abusing the ecosystem that supports them for decades. However, the magnitude of environmental concerns can leave individuals feeling helpless and unsure of how to make a difference.
There is a long list of problems plaguing our planet, but three dominate: climate change and global warming; water pollution and ocean acidification; and biodiversity loss. To protect the only planet we know where life can thrive, we must address these three concerns immediately and proactively. Plus, concentrating on these three key areas will have a trickle-down effect on other environmental concerns, such as ineffective recycling systems and food waste.

 

Let’s take a look at three pressing ecological problems and the approaches that can be taken to address them.

Problems with Climate Change and Global Warming

Global warming and climate change are a worldwide threat that are largely caused by human activity.An increase in global average temperatures, extreme weather events, rising sea levels, and other negative changes have been attributed to the increasing levels of carbon dioxide and other greenhouse gases. All forms of life are being affected by these shifts. One of the leading causes of these environmental problems is pollution of air, land, and water caused by excessive deforestation, industrialization, and overfilling of landfills, all of which release CO2 and contribute to greenhouse gas emissions. Some good ways to deal with these issues are listed below.

  • Foster the development and production of environmentally friendly tools.
  • Every type of building, from offices to homes, should strive for zero waste and zero emissions.
  • Smart technology, such as stationary compactors, can be used to increase waste compaction in landfills, making more room for more useful activities. It’s available in a variety of sizes and shapes to accommodate any amount of garbage.
  • To lower atmospheric CO2 levels, we must increase forest cover, restore seagrasses, and increase the use of agricultural cover crops.

 

Ocean acidification and water pollution

Some of the leading causes of water pollution include rapid urbanization, improper sewage disposal by industries, oil spills, the disposal of chemical or radioactive wastes, and plastic pollution. Many countries around the world are currently facing a serious threat to human survival due to water scarcity and pollution.
Somewhere in the neighborhood of 30 percent of all atmospheric carbon dioxide emissions are taken up by the world’s oceans. When seawater absorbs CO2, it undergoes a series of chemical reactions that increase the concentration of hydrogen ions, making the seawater more acidic and contributing to ocean acidification. As a result, it becomes more challenging for mollusks, deep-sea corals, oysters, and other marine organisms to produce and maintain their shells and other calcium carbonate structures because there are fewer carbonate ions in the seawater.

 Improve existing marine protections

  • Biodiversity is important because it keeps ecosystems stable and provides us with food and other life-sustaining resources. Humans are wreaking havoc on biodiversity in many ways. These include the destruction of habitats, changes in climate, pollution, secondary extinctions, and the introduction of new species. Several strategies exist to combat the extinction of species.
  • The government should enact stricter laws and policies to protect biodiversity.
  • Stop the destruction of habitats and promote their restoration.
  • Incorporate eco-friendly practices into your daily routine.
  • Get rid of unwanted pests.
  • Improve biodiversity conservation efforts through knowledge dissemination.
  • The most important step in protecting this gift we call home is gaining an appreciation for it. Those of us who care about the health of the planet for future generations have a responsibility to do what we can to mitigate the effects of environmental degradation.

cars-environment

 

Not surprisingly, cars, car services (like Recovery car London), car transportations, and roads play an important role in air pollution and global warming. Today, cars mobilize 83% of all passenger transport, 9% by train and 5% by bus. Between 1990 and 2012, passenger traffic increased from 744 to 9.83 billion kilometers, an annual increase of 1.3%.

Positive Point

For 45 years, automobiles have used 4% less energy. Although the number of vehicles in circulation is increasing, technological advances and reduced average mileage by manufacturers have a positive impact on fuel consumption and emissions.

 

CO2

The major greenhouse gas accounts for 35% of the world’s emissions, but the transport sector is France’s largest carbon dioxide emission (CO2), with emissions of 110.7 billion between 1990 and 2011.

It increased from tons to 120.4 billion tons. Although not directly harmful to health, CO2 creates a greenhouse effect that enhances the atmosphere’s ability to retain heat from the sun.

Air pollutants

In addition to CO2, cars emit other substances, some of which are especially harmful to health. Particulate matter is one of the air pollutants.
In French soil, Ademe (Environmental Energy Management Agency) reports that exposure to PM2.5 particles (less than 2.5 microns in diameter) reduces life expectancy by 8.2 months.

According to the WHO (World Health Organization), PM10 particles (less than 10 microns in diameter) cause 6% of premature deaths in France. Half of these particles are due to road traffic. In addition to respiratory and cardiovascular disease, studies have shown their detrimental effects on reproduction and fetal and neurological development.

Public Health Issues

Another pollutant emitted from exhaust fumes is nitrogen oxides (NOx), which are composed of nitrogen oxides (NO) and nitrogen dioxide (NO2). Not only do they affect global warming, but nitrogen dioxide (NO2) is present in the form of irritating gases that can penetrate deep into the lungs. In France, road transport accounts for 56% of NOx emissions.

Ozone (O3)

This is also an aggressive gas that causes severe eye and respiratory irritation. Carbon monoxide (CO) is a cardiopulmonary toxin. At low doses, the oxygen supply capacity of the brain, heart, and muscles is reduced. Volatile organic compounds (VOCs) have little direct effect, but sulfates (SO2) cause dyspnea, coughing attacks, and asthma attacks.

 

According to WHO,

Air pollutants kill 3 million people each year in France. But thanks to advances in the automotive industry, even if the oldest cars continue to cause damage, the latest cars have better environmental records which is an important factor why we should protect the environment. But it’s still a long way off.

A little more numbers?

Today, private cars account for 60% of the consumption of petroleum products in the transportation sector, which in itself accounts for 32% of France’s energy consumption. The share of roads in the total CO2 emissions of the transport sector has been stable since 1990, but it accounts for the largest share at 95.2%. Cars account for 56% of CO2 emissions from road transport.
