Recommended: Human impact on the ecosystem
In the past 50 years, we have drastically changed the environment to meet our growing demands. These alterations are causing major problems in several ecosystems. Living unsustainably, changing natural order, and reversing the degradation of ecosystems are the three main problems we face.
Our ecosystem provides free services like water supply, waste treatment and detoxification, water purification, natural hazard protection, regulation of air quality, regulation of regional and local climate, regulation of erosion, spiritual fulfillment, and aesthetic enjoyment. We live off of these services and often use them at a rate too high for replenishing. The usage of fisheries and fresh water has reached a stage that surpasses sustainability. Fisheries are being overharvested to meet the demands of the growing population and we’re overdrafting the groundwater supplies. The main idea is that if we continue to use our resources at such high rates, soon we will have nothing left for future generations.
Another main idea is when we unnaturally increase one ecosystem service it will cause the degradation of another. This is also known as disrupting an ecosystem. When you change, enhance, or modify the order of anything, everything gets affected. Human

Some of the goals include hunger, child mortality, and providing clean drinking water to those in poverty, but in order for that to happen, we would have to stop most ecosystem services from being degraded. Most problems arise from undernutrition and disease. Some sickness comes from people drinking unsanitary water. The other ailments are strongly influenced by ecosystem like malaria, schistosomiasis, and lymphatic filariasis. The goals are attainable, but these involve serious changes in policies, institutions, and practices that aren’t currently under
There is no such thing as just changing something from one part and not having its effects distribute throughout the entire ecosystem. As an ecosystem continues changing and evolving, so will the organisms living around or in it. We must adapt to the environment or we will become extinct, unable to adapt into the rapidly changing environment we live in. Althout human impact on an environment may benefit us, it can also be harmful to nature. By taking care of what we do to the environment, we can prevent future negative changes in the environment and preserve earth’s natural state.
...uring the age of discovery, it is that environments and ecosystems are fragile and can be easily altered with devastating results. Therefore, as humans continue to discover exciting new worlds, either in the darkest depths of the ocean or on the surface of a strange new planet, it is important that we as humans consider the ecological impacts that may result from those discoveries.
With a coastline of over 202,000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around $5 billion a year, being one of the world’s most valuable. However, the coasts have not been treated with respect; overfishing, over consumption, and wasteful practices have deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries is projected for 2048.
The ecosystems around the world are vital aspects of our everyday lives. Without the many resources and materials we harvest or use, life as we know it would be drastically different. In modern society, money is prioritized over essential benefits from nature. Due to this unfortunate truth, the stability of the environment has decreased on a global scale. Several of these issues include pollution, destruction of habitats, and causing species to go extinct due to events such as overfishing. Another human-caused problem is deforestation, particularly in the Amazon Rainforest.
This would be food chains. Food chains are a key part in any wildlife around the world. They are a system that shows what eats what from the plant-small prey-Large predators. In our lakes smaller fish eat aquatic plants , the smaller fish are eaten by larger predators and so on. But if one part of the food chain is messed up, like if all of the large predatory fish were fished out, there would be nothing to eat the small prey fish. This would cause the small prey fish to overpopulate and more mouths to feed. This would cause the aquatic plant population to decline. Now you see how one slight change of a part of a food chain can screw everything up. Which brings us to our next
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
“We are consuming the Earth’s natural resources beyond its sustainable capacity of renewal” said by Herman Daly, Beyond Growth, Boston 1996, 61[1] .
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
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
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
The world today is vastly different from what it was before urbanisation and industrialisation had taken its toll on the world. Since the turn of the new millennium the issue of the environment has suddenly evolved into a widespread issue which is greatly discussed throughout the world. No longer are humans living in a world where the environment is serene or stable but much rather becoming unrecognisable and diminishing before our eyes. The plants, trees and flowers are life forms which God has created for us to enjoy its beauty but it is now solely up to us and many other organisations to protect preserve and respect how fragile our environment really is.
Sustainability Revolution: Earth, the planet we call home, is a complex system made of interdependent parts and pieces of life that are constantly changing. Earth’s planetary system has maintained a balance of dynamic equilibrium—it has been sustainable— since its beginnings about 4.5 billion years ago. This balance, however, has been progressively disrupted by us—humans— especially during the last few decades. Mother Nature has provided us with natural resources and the habitat for all species to sustain life on our planet. Since the industrial revolution, we have maintained a belief that these resources are infinite, and that economic growth and our attempts to improve our standards of living can continue forever. All forms of human economic
Some main causes of Endangerment are habitat loss, pollution, hunting, competition from non-native plants and animals, plant collecting, logging, clearing forests, and trading animal parts. The growing population also causes some effect because man cause most problems. Diseases or viruses are al...
Agenda 21 is not just about making improvements in “nature”. It also includes plans of action regarding poverty, hunger, ill health, illiteracy, as well as the continuing deterioration of the ecosystems. The success of Agenda 21 is contingent upon integration of environmental and developmental concerns and greater attention to them. It is also dependant upon the fulfillment of basic needs, improved living standards for all, and better protected and managed ecosystems. Only if this is accomplished can we be assured a safer, more prosperous future. No nation can achieve this alone, however; if all nations
