The environment plays a significant role in life. It provides indispensible necessities to humans, animal life and plant life, such as water, food, shelter, and air resources. Meanwhile, human everyday actions and decisions are negatively impacting the environment, causing pollution, deforestation, overfishing. As the human population increases, it is understood that the environment will change; scenic roads become busy interstates, livestock pastures transform into shopping centers, peaceful forests are destroyed to make room for waste. It appears that the earth is being led to a dim future. As mere visitors of the earth, humans need to recognize the issues facing the environment and take action.
In the Environmental Health Science (EHS) program, students learn to access, prevent, and control factors in the environment that can potentially affect health. Its overall goal is to prepare students for careers as environmental and occupational health specialists. Specialists apply knowledge, research, enforce, and write legislation, and lobby on behalf of the environment.
1. NEGATIVE IMPACTS
1.1 AIR POLLUTION
One negative impact seen across the globe is air pollution. The United States Environmental Protection Agency (EPA) defines it as “the presence of contaminants or pollutant substances in the air that interfere with human health or welfare, or produce other harmful environmental effects.” It wasn’t until approximately the 1960s that people began to notice and draw attention to the diminishing quality of the environment. Congress responded by passing the National Environmental Policy Act (NEPA) in 1969, a movement by the federal government towards environmental stewardship. NEPA established a United States national pol...

As small mobile groups of hunter-gatherers adopted a sedentary lifestyle, they mastered both agriculture and animal domestication. These small settled groups quickly evolved into cities and towns that encompassed the entire globe. Today the estimated population of the world is over 6.2 million people.1 As the population has grown, it has had several deleterious effects on the Earth. These include climate changes, the spread of diseases, declining food production, deforestation, and environment pollution (particularly air pollution). As people have become more conscious of these harmful effects, they have begun to devise strategies to combat this problem. Among the suggested responses include a switch to renewable energy, a call for zero population growth, and adopting sustainable agricultural practices.

Non-native species is a term commonly used to refer to plants and animals introduced to a foreign environment mostly by humanity either intentionally or accidentally.. Such exotic invaders die because they cannot adjust to the introduced ecosystem, which implies they entail domestication. However, some thrive to the extent of dominating their new ecosystem by spreading quickly and widely. These kinds of invaders do not have their native predators and with time take over the ecosystem from native species (David and Sweeney 53). The term invasive can refer to introduced species and diseases as well. Approximately 50,000 non-native species have been introduced in the US up to date. Non -native species can be referred to as invasive if it poses danger to the ecological systems. Introduced species that need to be taken care of by humans in order to thrive are known as ornamental plants. Other than human activities, non-native species can be introduced through climatic change due to natural selection whereby new organisms that can survive are established. Continental drift is another factor known to contribute to the presence of non-native species. However, these are slow processes and the most common is human activity. During past centuries, immigration has taken place globally man relocating to extremely far destinations whereby his movements yielded to the transportation of plants as well as other organisms to completely new environments away from their native ecosystem. To protect these ecosystems, native species and the economy of US, respective authorities have devised regulatory measures meant to control the introduction of new foreign species by humans. Invasive species encounter extremely strict measures imposed on them despite...
Societies found throughout the globe are interconnected through our ecosystem. Over the years, our ability to think of climate change on a global scale has improved, but we are still far from solving our environmental issues. While on our quest for improving quality of life and fulfilling our dive to expand, we as a combined human race are the cause of deforestation, pollution of our
At our current rate, humankind is speeding towards a frightening and destructive inevitability. Endangered species and biodiversity are sacrificed to line the pockets of billionaires; urban sprawls are favoured over natural land; new coal mines are opening; and indigenous cultures are being drowned in cement. Our environmental ecosystem is fragile to begin with, and we are steadily and masochistically doing more and more irreversible damage.
Nowadays, as our world develops with a dazzling speed, there are also a lot of environmental
Natural environment changes are increasingly threatening environmental sustainability. An environment is said to be every object that is found on earth whether living or non-living. We human use resources of the environment (water, land and air) for our own benefits. The more we use the resources of the environment the more we apply or cause pressure on the environment. When there is much pressure on the environment in such a way that the carrying capacity of the environment is over exceeded and can no longer repair itself, this may harm the environment is a big way. Some of the environmental resources such as ground water are non-renewable so if we over use them we lose them forever. Therefore it is important for us to know that our environment is important to all of us so it is important for us to take care of it by protecting it and it is also important to raise awareness on how to protect our environment. It is important for us to use resources with much care and it is our responsibility to protect the environment, it is not a duty for the government only but it is a
According to the internet human behavior has a very big affect on the environment. Environmental settings such as air pollution, oceans, energy, or noise are all sources that can negatively impact the environmental quality and conditions. Our daily routines have a huge impact on the environment and we do not realize it. New laws that are passing and educating people will help a lot. People are being educated on how to use less water, use our cars less, how to use less energy, and even taking reusable bags when going grocery shopping because plastic bags are very bad for the environment. There are simple solutions that can help in getting started with these efforts. Every little step and effort we make in our daily routines count.
All of the above environmental issues clearly indicate that the natural assets that humans take for granted are in grave danger. Most of the damage on the environment caused by human expansion is long-lasting and in some cases permanent. There is no doubt that the human population will continue increasing and the condition of the environment will exacerbate. Therefore, only a sustainable approach toward conserving what currently exists as natural resources could counteract the detrimental effects of overpopulation on the natural world.
Many people assume that the environment is not in danger. They believe that as technology advances, we do not need to worry about renewing natural resources, recycling, and finding new ways to produce energy. They state that one person in the world does not make a large difference. In reality, each individual's contribution greatly affects our environment. Our natural resources are slowly disappearing, and we must work together to save them and the Earth from ruin.
Human interaction with the environment is changing constantly. In recent years, the environment being highly valued by most, is used and altered by diverse community of the people for different interests and values.
The environment around us gives us the habitat to live, is a condition for our existence and development so that protecting environment which is one of today’s most serious issues means protecting our lives. But almost every day we hear a new problem badly affecting the environment. The list of the new difficulties seems to be endless. We are all aware of these concerns and can admit that we caused them. Now, environmental protection is not the work of a single individual as it is the responsibility of the whole community, of every single person exists on this planet. The measures range from each citizen to the government.
The environment today is not in a good condition, Climate change is evident, and oceans are getting polluted. Rainforrest's are decreasing in size due to deforestation and illegal logging. Animals are getting extinct due to the destruction of their habitats. Natural resources are being consumed at very large amounts, and get wasted. There are different ways these problems can be addressed, one option is environmental management. Environmental management focuses on conservation of natural resources, protection of habitats, and impact of humans on the environment. Conservation of natural resources is the smart use of the world's resources by humans, through this waste production is limited, and there will be less garbage in the world. By conserving
On this earth we have so many problems. There is a leak in the ozone layer, we are running out of oxygen, there is not going to be any more clean water soon, et cetera.
“Only when the last fish is gone, the last river poisoned, the last tree cut down...will mankind realize they cannot eat money” Greenpeace. Every person in this world are working hard and earning much money to make their future sustainable. Most of people dream of a happy family in a beautiful house, but we did not imagine about environment in those days. Industries and vehicles are releasing carbon dioxide, which damage our environment. While we are dreaming about our bright future, our earth has been raped by our activities since humans are exist. When people realize about environmental problem, they push their responsibility to solve and protect our planet to the large organizations. Instead of blaming governments and factories, people should join individual hands and make our future come true. Everybody nowadays is busy in his or her daily life, there is three ways to protect environment, which can matched up with our life style.
