Recommended: Effects on the environment from loss of biodiversity
The study, by 1,360 experts in 95 nations, said a rising human population had polluted or over-exploited two thirds of the ecological systems on which life depends, ranging from clean air to fresh water, in the past 50 years.
"At the heart of this assessment is a stark warning," said the 45-member board of the Millennium Ecosystem Assessment.
"Human activity is putting such strain on the natural functions of Earth that the ability of the planet's ecosystems to sustain future generations can no longer be taken for granted," it said.
Ten to 30 percent of mammal, bird and amphibian species were already threatened with extinction, according to the assessment, the biggest review of the planet's life support systems.
"Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fibre and fuel," the report said.
"This has resulted in a substantial and largely irreversible loss in the diversity of life on earth," it added. More land was changed to cropland since 1945, for instance, than in the 18th and 19th centuries combined.
Getting worse
"The harmful consequences of this degradation could grow significantly worse in the next 50 years," it said. The report was compiled by experts, including from U.N. agencies and international scientific and development organizations.
U.N. Secretary-General Kofi Annan said the study "shows how human activities are causing environmental damage on a massive scale throughout the world, and how biodiversity -- the very basis for life on earth -- is declining at an alarming rate."
The report said there was evidence that strains on nature could trigger abrupt changes like the collapse of cod fisheries off Newfoundland in Canada in 1992 after years of over-fishing.
Future changes could bring sudden outbreaks of disease. Warming of the Great Lakes in Africa due to climate change, for instance, could create conditions for a spread of cholera.
And a build-up of nitrogen from fertilizers washed off farmland into seas could spur abrupt blooms of algae that choke fish or create oxygen-depleted "dead zones" along coasts.
It said deforestation often led to less rainfall. And at some point, lack of rain could suddenly undermine growing conditions for remaining forests in a region.
The report said that in 100 years, global warming widely blamed on burning of fossil fuels in cars, factories and power plants, might take over as the main source of damage.
Humans can not be the only thing that is hurting the Earth. When you really think about it, Earth goes through a lot of natural disasters, which cannot be controlled. According to an activist, Tim Haering, “Tsunamis, floods, volcanoes, earthquakes, tornadoes, wildfires, disease nature kills more than we kill each other.” Earth throws in all of these natural ...
Humans have played major roles in destroying and protecting a variety of ecosystems. Currently there are many people involved in changing others views on protective earth practices and aware of their impact on changing environments. This is best seen in climate change, conservation movements, and hunting and fishing practices and policies. However, there are already major impacts from climate change, particularly in northern areas, the future impact of a changing climate is rarely considered when determining land-use, including environmental assessments. With expanding resource removal behaviours, the impact of a changing climate and human activities on vulnerable wild life and ecosystems is a big problem. Adding to the problem is a lack of
and is existing surely because of humans themselves- overpopulation. “Overpopulation is the problem” and causes other externalities such as pollution, deforestation, and a greater handful of biodiversity losses. In addition, overpopulation causes economic and political factors such as more consumption per person and the reduction of resources that can be provided per person. This contributes to the strain on ecological systems and the economic and population growth. With overpopulation, many resources become finite and an umpteen amount of ecosystems are being destroyed. Overpopulation relates to the impact of humans on pollution. Obviously with more human life, there is more necessity for jobs such as factories that give off fumes, automobiles, and the use for burning fossil fuels. In greater extent, this leads to an environmental factor in that it accumulates chemicals in food chains such as mercury, arsenic, and copper. It can lead to political problems as well, when trying to interact with other countries and stop the problem of global pollution and eventually endin...
Animal threatening to extinction is not a myth, is real and is happening. As the world becomes more interconnected and globalized, trading and economic issues has been the most important agenda to most countries, where animals and the environment has been ignored, and whatever benefits us even if harming the latter is not considered wrong. In my opinion, despite knowing the impact to us human beings behind animal extinction, we should not let animals that have lived for millions of years to go extinct solely because of us and our selfishness. We have to start thinking about the earth as a whole where we share with all the animals, and not human beings as the dominant group.
Climate and change and habitat destruction has left animals extinct and many more endangered. Continuing this pattern of carnage could leave no more plants, animals, or environment left to talk and write about. Hopefully for years to come, our national and unique environment will continue to be a large component of American
Consumption of resources is currently the highest it has ever been: “Humans have fundamentally modified the terrestrial landscape and marine environment in which ecosystems develop, with some 50% of the land surface being modified for agriculture (about 36%), urban, and other human-dominated purposes” (citation-footnote). Not only have humans consumed a great deal of materials and therefore demand a large energy production, but has also generated waste that has been inputted into the environment. “As a result of hyper-fertilization, the amount of reactive nitrogen at the Earth’s surface has approximately doubled by means of the Haber-Bosch process, a perturbation of the nitrogen cycle that may be the greatest since Proterozoic times…”(citation). Thus, the Anthropocene is unlike other epochs, as the sheer amount of consumption and waste production is the highest it has ever
There is no doubt that human activity is having a significant impact on our environment. These environmental impacts include depleting our natural resources, air and water pollution, climate change, destruction of habitats, and loss of biodiversity. Because of these growing concerns, we need to learn how to live sustainably. Living sustainably will allow us to conserve our limited resources more wisely so they will be available for future generations (Withgott & Brennan, 2011, Chapter 1).
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
It is unfortunate that within the past 100 years our worlds' economy has driven itself into a deep hole with the reliance on a "black gold" called oil. Since its discovery, it has been purified to produce many different forms of energy such as light, gasoline and more. Since technology has enabled mankind to discover more capable methods of transportation, mankind has exploited its power over nature and produced machines such as the combustion engine. In combustion engine's, oil explodes to move machinery, and emits a very toxic byproduct called CO2. Carbon is incredibly dangerous to the earth's atmosphere, and erodes huge holes in the ozone layer of our earth. This erosion causes global warming and climate change that is permanent and irreversible. The impact of global warming will not only ...
Jacques-Yves Cousteau once said, “Overconsumption and overpopulation underlie every environmental problem we face today” (“Population,” Internet). With the current statistics, Jacques could not be more accurate. Every second, 4.2 people are born and 1.8 people die, which would be a net gain of 2.4 people per second (“Population,” Internet). At this steady rate, the environmental health is spiraling downwards, and it is safe to assume humans are responsible for this. As the population increases, harmful effects on the land, water, and air also do.
Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.
Everyday, alarming amounts of toxins are released into the atmosphere. Over the recent years global climate change, better known as “global warming” has become a worldwide problem facing our planet, and as the world becomes continuously warmer, the effects that climate change will pose to our planet and to the people who live on this earth, will be detrimental.
Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution, or contamination, of the environment. Much of the world's air, water, and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. As a result of these developments, governments have passed laws to limit or reverse the threat of environmental pollution.
Social ecology observes humans as the main cause of the destroyed earth, by overpopulating it. The world is made up of numerous people, with different races and religions, it’s because of the bad habits men and women have created which have lead to a polluted earth (Carlson, Felton, 2001). Mur...
The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
