Very detailed and helpful, uglified take on QR codes.

Step out into the everyday world as an average American and you will witness an entanglement of varied body size, my writer did a great job and helped me get an A.

Species become endangered every day and so far, it hasn’t affected humans. Plus humans aren’t responsible for the extinction of animals, or are they? Humans have a responsibility to help save endangered species because we are the top reason for endangerment because we clear these creatures’ habitats by deforestation, mining, or expanding and most of these animals, plants, or insects are at risk because of human activity like pollution from cars or factories. There are still people who highly believe that endangered animals shouldn’t be conserved. Many would argue that the cost on saving these animals is too high and outweighs the possible benefits. Sure the Earth is changing, but animals have to adapt to it if they want to survive, just like humans.

Also, most animals don’t contribute anything to humanity, right? In my opinion many of these people are just making up excuses out of selfishness. Humans choose to ignore these problems because they don’t have an immediate effect on us. They choose ignorance over responsibility because it’s the easier route. Think of an ecosystem like a game of Jenga. The players are humans and natural selection.

Each block supports one another and each time you remove a block you risk the entire tower falling. Humans carelessly remove blocks without much thought to them while natural selection carefully chooses each block and makes sure that other blocks are only slightly affected. Eventually, humans are going to remove a block that will send the entire tower tumbling down and along with it, each individual block. Just like the blocks, animals depend on one another, and at one point one species will disappear and it’ll cause a chain reaction. For example, let’s say that a certain plant species goes extinct.

Other animals depended on that plant for food and without it, the whole food chain is messed up. Humans are largely responsible for extinction. We clear forests and other lands to build houses or mine on, by doing so we are taking away an animal’s home. We destroy a creature’s habitat and now, they have nowhere to live. Things like pollution and global warming can also contribute to the loss of habitat or extinction. For example, polar bears rely on the arctic sea to hunt and live.

Anything and everything — one is that they look like robot barf. She does not have any real life experience. With whatever phone numbers, mostly it’s weeded out by filters so we don’t even see it. In 2012’s exam, read our guide to learn what MLA is and how to make properly formatted citations.

The melting of the ice only means that polar bears will have less access to food, mating, and become extinct. 3 of the world’s polar bears could disappear by the end of the century. Humans help global warming by burning fossil fuels like coal and oil into the atmosphere. These gases only add on to the amount of greenhouse gases in the atmosphere and help higher temperatures. Also, trees help remove CO2 from the atmosphere and deforestation slows down this process. Lastly, many animals provide knowledge that help in science and biological sciences.

A loss of biodiversity can mean the loss of possible discovery of treatments for diseases or health problems. For example, a flower type called Rosy Periwinkle almost went extinct due to deforestation in Madagascar. The flower was later found to have a substance that fights and cures Leukemia and Hodgkin’s disease. If this flower had gone extinct, humans may have never discovered this and it would’ve had a very different effect in the medical field.
