Imagine a world without any animals just humans. It's scary isn't it? This could happen on Earth if we don’t change our lifestyles according to scientist and non-profit organizations called save our seas and world wildlife. Earth is rapidly being destroyed by mankind in ways like overfishing, deforestation, and not recycling plastic properly. These things are then leading to a loss in bio-diversity, contamination in water, and ultimately killing our planet. Everyday things that we do like driving a car, flying in a plane, or even taking a train are greatly impacting the Earth too. We are impacting our Earth in such a negative way that eventually we could lose all of our resources and end up killing ourselves due to the lack of resources and population if we don't make changes in the oceans.
One reason Earth is rapidly being destroyed by mankind is because of overfishing. Overfishing is causing a major loss of bio-diversity in the ocean as stated by a non-profit organization called save our seas. Each year the sea food industry halls in about eighty million tons of seafood which is approximately two trillion marine animals. Forty percent of these animals caught are caught as bycatch which means they are thrown back into the ocean as waste, most of them dead or wounded. Scientist predict that by the year 2050 all fish populations will be gone from our oceans if the fish industry continues to fish at their current rate.
Since the 1950s, ninety percent of our large fishes have disappeared from our oceans this includes about three hundred million whales, dolphins, porpoises, and sea turtles. According to Pavan Sukhdev "We are in the situation where forty years down the line we effectively, are out of fish"(Save our seas 1). The most...

...e the most targeted places such as Brazil, Indonesia, and Thailand. Deforestation is typically done to make more land available for housing and urbanization, timber, large scale cash crops such as soy and palm oil, and cattle ranching. Effects of deforestation include loss in bio-diversity, carbon emissions, and soil erosion.
The topic of how human life is impacting the environment doesn’t only personally impact me but everyone on this planet. We need to come together are start realizing that we are taking advantage of our resources and fifty year down the line we might not have anything left. This is a result of us not thinking clearly on what we are doing and overfishing the ocean, not recycling our trash correctly, and demolishing the forests. We cannot take back what we have already done but we can help prevent the destruction of our planet in the coming years.
The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
Simply, overfishing depletes fish stocks. The consumer demand for fish has risen dramatically over the past decade or so, so much that fisheries are designing new and innovate ways to catch more fish, and at a faster rate to meet consumer demands. What fisheries do not realize, though, is that their removal of fish from the oceans is too great and far too fast for new fish stocks to be made. So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)
Rupert Murray’s The End of the Line focuses on the depletion of the oceans fisheries and the devastating effects it has already begun to have on ecosystems and less affluent populations. The film opens with a description of the tribulations of Newfoundland. Once possessing waters so populous with cod that one could “walk across their backs in the water,” improved technology and larger fishing vessels began to deplete the fish stocks. Despite placing a moratorium on fishing in 1992, the fisheries had already been depleted to the point of complete collapse. Similar processes are occurring around the world, as only .6% of the ocean is restricted to fishing vessels. According to the film, much of the ocean’s catch has declined by 90%; the continuation of current trends if continue, stocks will collapse by 2048.
Alina Bradford from Live Science, explained in her article about deforestation and how there are different causes of deforestation such as, selling trees for products such as paper, homes, house hold furniture, and other house products. She also states that other causes of deforestation are making room for agriculture purposes, and to create room for cattle ranching as well. On the downfall though there are disadvantages of deforestation as well too as she explains. One of them in fact is deforestation is contributing to climate change and also the greenhouse effect too as well by emitting a great amount of carbon dioxide (CO2) into the earth’s atmosphere. The effect from that happening is carbon dioxide is a greenhouse which absorbs heat from the sun and doesn’t let it escape into space. As that doing so, the Earth is heating up each year due to deforestation. From that, it will cause global warming and climate change too. There are causes and different purposes for deforestation but there are significant effects that could end up due to deforestation based on Alina Bradford’s
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 ...
Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .
By definition, deforestation is the permanent destruction of forests in order to make the land available for other uses. Such as the conversion of forestland to farms, ranches, and urban use. Food and Agriculture Organization of the United Nations has reported that an estimated 18 million acres of forest are lost each year and about half of the world's tropical forests have been cleared. Also, according to Bastien Sachet, “…tropical deforestation is responsible for approximately 20% of world greenhouse gas emission…Every year, 13 million hectares of the world’...
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 dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
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.
“Earth is losing mammal species 20 to 100 times the rate of the past. Extinctions are happening so fast, they could rival the event that killed the dinosaurs in as little as 250 years,” says sarah Kaplan of the Washington Post. Scientists are in agreement, we are teetering on the sixth mass extinction and humans are the cause of this round. Due to the destruction of forests, pollution of the ocean and freshwater sources alike, over hunting, over fishing, and mass amounts of CO2 produced by the human population we are destroying the earth that sustains us.
Humans are destructive. Not a lot of us think about how what we do affects the world around us. We almost act like we are the only ones on this planet. We go around polluting and destroying our world with no regard for our actions. The things that live out in the wild are paying the price for it. Every day that passes there is another animal or plant that is placed on an endangered list. This is happening at an alarming rate. Because of man’s desire to expand and conquer their surroundings, there are animals and plants that are on the brink of extinction that will not be around for our kids and future generations to enjoy if something is not done about it now. This problem has been going on for hundreds of years. There are animals and plants that can only been seen in paintings or early photography. It is because of our early ancestors that we have this problem today and we have to do more to prevent more animals and plants from disappearing forever.
General Information: First off, deforestation is the clearing of forests or areas with trees to be converted into something else after. There are a few different ways forests are cleared. Clear cutting is simply removing everything in sight. Patch cutting is the removal of trees in specified patches. Strip cutting is removing trees in selected strips. The most environmentally friendly method is known as selective cutting. This is the removal of only selected trees, leaving the others un-harmed. The technique used most during deforestation is the slash and burn technique. This uses the basic cutting method of clear cutting, but afterwards everything that remains is burned to ash.
Human Impact on the Environment Introduction = == == == ==
People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
Deforestation is the elimination of existing trees from the earth; attributable factors include urbanization, logging, ranching, and farming and to some extent land speculation. Land speculation can be included as cleared land is more valuable than forested land. Deforestation, done in the name of progress, and the long-term, devastating effects of it, is killing our planet.
