Recommended: Human impacts on ecosystems
They say that we leave with us steps in the Earth. Reminders to others that there once was life here and there is a strong imprint to show for it. Animals leave prints in the sand on beaches and in the tender soil of land. We,as humankind,leave prints of destruction. Destruction? How could that be? Is what you may ask yourself,but think about it. Daily we do not think about all the small choices we make that could possibly be harming our wildlife and their environment. We leave our imprint of destroyed beach dunes and dug up coral reefs. We leave our trash to rot in fields and we don 't think anything of it. We do not think about the harmful effects we are having on our planet and the animals whom share it with us. We must start making a change …show more content…
In order to talk about the ways we can prevent our wildlife and there homes from being disrupted. We must first address the main causes at hand. These main causes would be: The destruction of habitat,hunting,and pollution. Firstly we should address the destruction of habitats. Since we,as living things,grow and populate,we eventually need more space to spread out. In order to make more room for us we must cultivate to different areas and ultimately disrupt the all ready existent ecosystem there. Taking out a vast amount of wildlife without even realizing it. Loral Wilkonson,states in her article,How we Save Endangered Species,that "scientists estimate that up to one-third of U.S. species are at increased risk of extinction, and more than 1,300 U.S. plants and animals already have been federally listed as threatened or endangered." ( Wilkonson,para.3,reference 1.) This …show more content…
Pollution is the main offender in the disruption of several animal and plant ecosystems. We are the base problem for the pollution that is taking away from our wildlife and plant life. We burn heaps of garbage that is dumped out at sites, with machines that run on fossil fuels. These fuels are tainting the air and having a national effect on the world around us. This effect being,global warming. With temperatures at a rise from the constant burning of fossil fuels and the sickly gas puffing out of our mufflers,we are slowly killing wildlife across the globe. One example of an animal species that is being greatly impacted by global warming is the polar bear. Due to the rapidly changing climate temperature,sea ice platforms are breaking off and slowly drifting apart. This makes it very difficult for polar bears to hunt because they can only spend a short time submerged under the arctic waters before they have to reach land,in this case sea ice. Although the polar bear has not been placed on the endanger species list,researches say that they could be on there very soon. Another issues surrounding pollution and the safety of our wild life would be the contamination of soils. The contamination of soils has been cause to the tainting of vegetation that our wildlife ingests. This contamination is caused by metals and other things such as coal ash. Due to past use of
The effects of deforestation around my home and throughout my state are becoming more evident every day. When a deer or other wild game loses its home, they move into cities, urban areas, and parks; thus causing issues with the human population. Most people living in Illinois have hit or nearly killed a deer driving on Southern Illinois roadways. This common occurrence could be kept at bay or maybe even avoided if the deer and wild game had more space to reside. There are many points that coincide with this reality but the main issues are the small subtle ones that affect everyday life and are often overlooked. Picture the Illinois we will leave for our children. Do you see a lush green forest or miles and miles of concrete and steel?
The Zoological Society of London (ZSL) breeds Globally Endangered animals and then introduces them back into the wild. ZSL states that the main reasons of extinct species are: Poaching, Pollution, Climate change, and Over Population of the human race due to the need of homes, shops, hospitals and other amenities. The rain forest once encompassed four billion acres of Earth has now depleted to 2.5 billion acres of Earth within a few hundred years. Wetlands have also been destroyed and the provide drinking water for wildlife and humans. Maybe the solution to this problem is not locking away the animals that are endangered, but cracking down on the destruction of habitats. Maybe there should be places where property is restricted ...
Species are decreasing and becoming extinct over time due to climate warming. Animals and plants have developed and diversified from earlier forms to become more complex organisms. Not only have living organisms changed, but so has the Earth. Over time, the world itself has changed drastically, not just the climate but the way it looks as well. The ice on the arctic is melting, causing oceans to become more acidic, oceans became deserts and pollution from our everyday lives are affecting the ozone. It all adds up and changes the world negatively. When the world changes, so do the animals within it. Climate warming has been a big part of the change we see in the population of different species. The speed of climate change is excelling, which
There is no hesitation when it comes to whether humans impact the global environment. However, it is questioned in whether human’s ecological footprint is either negatively or positively impacting. In clear perspective, humans share from both sides and their ecological footprint is noted towards whether it will benefit or harm the environment around them. Topics such as overpopulation, pollution, biomagnification, and deforestation are all human impacted and can harm the environment, but some include benefits into helping the world around us with solutions to their problems.
Global warming has become a more prominent issue every decade since the mid 1900s. The increased temperatures are leading to substantial ice loss. This loss in ice is causing severe destruction to polar bear habitats and homes and is leading to their extinction. It also is affecting their food supply. Global warming is making it harder for polar bears to repopulate and is causing a decrease in the overall size of each bear. The chemicals associated with global warming are getting into the food chain and eventually into the polar bears themselves. Global warming is causing the extinction of polar bears in the arctic because it’s destroying their homes, decreasing their food supply, is affecting chemicals in the air and in their food, decreasing the average size of the bears, and contributes to a decrease in reproduction.

Many of these causes could be prevented fairly easily. If people today would just follow some simple rules, none of these would be as big as they are now.
ü AIR POLLUTION- Sulphur dioxide from burning fossil fuels leading to acid rain, carbon dioxide from burning of fossil fuels and methane from cattle and rice fields leading to greenhouse effect and global warming. ü LAND POLLUTION - pesticides, herbicides, and nitrates wash into rivers and lakes affecting food chains. Habitat reduction by Humans = ==
Global warming is one of the most serious problems that people all over the world are dealing with. In fact, however, many people may not realize that global warming also affects animals as badly as it does to human. All Americans should help protect animals from global warming because global warming changes animals’ habitats, decreases food supplies of animals, and even shortens animals’ lifespan.
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”). 2. And acid rain, which is created when water in the atmosphere mixes with chemicals, ravage through rain forests and can even kill fish. 3.
The effect of climate change is very high; it could cause animal life to become extinct. Climate change affects many kinds of animals. According to an article written on Climate and Weather, birds are highly affected by climate change. When the climate changes, birds lay their eggs earlier than usual They migrate into the nest earlier and in some countries, birds don’t even live anymore. (Climate Change effect on Animals and BirdLife). This shows how climate change, which is caused by excessive greenhouse gas in the air affects the animal
Many of the issues of biodiversity loss can be traced back to human interaction to the environment. One of the issues is alteration and loss of habitats. A lot of this issue is based on the destruction of habitats and for the land to be used for human consumption. The land is either used up for agricultural use or for neighborhoods. Destroying habitats and building them for our own use can have a positive impact on our way of living but a negative impact on the environment. We would gain land for building land for crops and communities to be built. The habitat for the animals would be destroyed and the species local to the land would either relocate or die. There are restrictions to deforesting land and there are organizations to help protect the land.
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.
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
Loss of biodiversity is an environmental issue that is causing a lot of global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth. There are measures that are being taken worldwide to prevent loss of biodiversity. Many wildlife sanctuaries have been built worldwide to preserve the lives of various endangered species. However, it is important to remember that every individual has a role in the protection of wildlife and biodiversity. Every human being should play his part of the role by following simple rules such as stopping others from the hunting of endangered species, preventing deforestation, encouraging reforestation and creating awareness among fellow human beings.
