Pros and Cons to the Ways Humans Impact the Environment

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

In contrast, the natural environment and wild animals were negatively impacted by human activities. Burning forests in untouched land made low nutritional soil. As a result of this, erosion took many areas and made empty fields. Also, wild animals lost their habitat because forests were disappearing and people changed landscapes. People were looking only at benefits to improve their lives, and therefore wild animals would not be considered.

However, the author of “Earth has lost half of its wildlife in the past 40 years,” states, “We have lost half of the animal population and knowing this is driven by human consumption, this is clearly a call to arms and we must act now… The earth must be protected from development and deforestation, while food and energy have to be produced sustainably” (Damian Carrington). The population of animals has decreased for many reasons that all point back to favoring industries rather

Leopold discusses conservation as homo sapien involvement to respect, love, and care for the ecosystem. That we need to step back at certain times to appreciate the environment, but also harvest from the landscape and bear fruit. So conservation involves both human and non human involvement. Understanding this concept further we need to understand how we do not care and respect the environment. We need to learn what our communities problem

Our lives involve the emission of theses dangerous greenhouse gases (Bushnell 25). Carbon dioxide has increased to

In conclusion, conserving wildlife is crucial to the survival of humans and the ability to produce medicines and other important materials. Animals don’t have a voice of their own, they need help before it’s too late. As you realize animals are essential in everything we do and if they leave we will quickly follow. Conservation of wildlife is extremely important because the future generations depends on it. If you decide to take no action, you are not only letting animals down, but you are letting mankind down. Don’t make animals

Humans have the ability to have a great impact on ecosystems. Living organisms are a significant

Since the Industrial Revolution we have practiced deforestation, burned fossil fuels, and as a result we have disrupted stable ecosystems. Advances in medicine and technology have given humans the ability to increase their carrying capacity. While increasing our carrying capacity we have also decreased biodiversity around the world. We have introduced different species in new environments to help ourselves

There are several threats to biodiversity that Carolan discusses, and many of these issues could be less destructive if there were a change in human behavior. One cause is energy production and mining, with oil and gas

An encroachment in the wildlife areas such as national parks has often led to the wild animals escaping from the parks and straying into the areas where human beings stay (Paul, 1986). The resultant effect is that the wild animals end up eating the domestic animals and at times leaving injuries on the human beings they meet on their way. Poaching on wild animals has also had a negative effect on the balance of the ecosystem. Most of the poached animals sooner or later become extinct from the universe thereby creating a problem of natural balancing in the ecosystem (Namara et al.

The population on Earth is expanding rapidly which goes hand in hand in the degradation of the environment at large measures. The human’s appetites for needs are disarranging the environments natural equilibrium. Our production industries are venting smoke and discharging chemicals that are polluting our water. The smoke that is emitted into the atmosphere holds unappealing gases such as carbon monoxide and sulfur dioxide. The high

Deforestation for agricultural purposes and the expansion of human habitats is happening around the world. This

Earth is the only place in the universe that can support human life. It is very important that we realize this fact and take very good care of it. Various human activities cause the destruction of earth. Human beings can live a few days without food and water however humans can last only a few seconds without oxygen. Various human activities lead to the aggravation of the quality of air. Gases produced by human activities mainly due to exploitation of resources and industrialization cause air pollution. Green house gases mainly chlorofluorocarbons; carbon
