In the Book Thresholds:The Environment by Bill Harris, he talks about changes in the world. Harris talks about how the earth can be considered a single organism just like people and trees. He also talks about how earth can be independent too. The main thing Harris talks about that is changing the world is the collapse of fisheries all over the world, people destroying the primary food sources and iron.
According to Harris Collapse is “worm and his co-authors define collapse as being when a part of the ocean where a particular fish species once plentiful and fished from has hit about 10 percent of its natural original population” (24). This quote means that collapse is when the fish species has about 10% of its original population, showing that when there are only 10% left of natural fish population fish are at there collapse. This has a huge affect on the world because fish in the water are dying and if fish continue to die less food will go around the world to eat. A Hole in the World
Another way that the world is changing is that people are destroying their primary source of food. This means that people are getting rid of their own sources of food by destroying the world. According to Harris “While changes in our atmosphere . . . may well, in and of themselves, make much of the planet hostile to human life, at the same time we are destroying the primary source of our food” (22). This quote means that even though the earth's atmosphere is making the planet hostile to human life, humans are also causing problems to the earth. People are not using the right about of nutrients when people first came to the world nutrient use was better, but as it excelled things changed through the world such as, fertilizer growth, iron use. The human body needs iron people according to Harris “become lethargic, don't sleep well, become depressed and tired, often gain weight, and are vulnerable to a wide variety of diseases”. (22). This quote shows that without iron life itself will be harder to survive in.

The movie The 11th Hour
In the movie The 11th Hour by Leonardo DiCaprio, economist, scientist, biologist and advocates discuss what is happening to the natural environment. The natural environment is earth and these people discuss what has been happening to it over the last hundred years. They go through many different things that can be the caused to why the earth has changed so much, but there are a few things that have changed the world to a great extent. Two main keywords that can be used for the world changing are deforestation, isolation and nature.
Deforestation is when forest are being cleared of the trees that are inside of it. Deforestation has had a huge affect on the world. 90% of the world's forest have deforested over the last hundred years. That means that out of 100% only 10% natural trees are still alive. That affects the world by a great amount because the life forms living on earth need trees for oxygen without any trees it is harder to breathe. If every tree in the world dies out people will also die because of lack of oxygen.
Another problem that affects the world a lot is isolation. Isolation is when something or someone separates their selves from others is something else. People live on earth, but even though they live on earth they isolate themselves from it. People don't realize that earth and nature was here before people were. People take advantage of the world that is in front of them and just change it into what they want. Instead of co-existing with nature people separate themselves from it and try to control it. Nature does twice as much work for free then the ecosystems do, but people still isolate themselves from it and try to ignore it. If people continue to isolate their selves from nature then they will worsen the world because they are not learning from it.
The last problem is nature. Nature is the trees, grass and bushes that are in forest and around the world. The main problem with nature being around is that people don't seem to realize it exist. People are not realizing that nature should be treated fairly too. Nature is taken advantaged of and stead of people respecting nature they use it and do what ever they want with it.
